* Homing Missile can catch and single out retreating Meepos, making them an easy kill.
Monkey King
[wiki] rating: 2.0 (winrate: 50% pickrate: 16%)Chaos Knight
* 
Wukong's Command and 
Boundless Strike combo can easily cause havoc on Chaos Knight by destroying all of his powerful illusions.
* Chaos Knight without Phantasm cannot deal with 
Jingu Mastery at all.
Meepo
* Monkey King can gain Jingu Mastery stacks on Meepo’s clones from 
Divided We Stand.

Winter Wyvern
[wiki] rating: 2.0 (winrate: 49% pickrate: 7%)Chaos Knight
* 
Cold Embrace protects targets of Reality Rift.
* 
Winter's Curse turns Phantasm illusions against Chaos Knight or a teammate.
* 
Splinter Blast deals decent area damage to Phantasm illusions.
* 
Arctic Burn's percentage-based damage quickly wears down Chaos Knight's health.
Additional:
* Winter Wyvern can make Chaos Knight's illusions attack the real one, provided the player knows who it is.
* Alternatively, Winter's Curse can make Chaos Knight and all his illusions attack one of his allies.
* Cold Embrace protects ally who is focused by Chaos Knight.
* Splinter Blast deals decent area damage to Chaos Knight's illusions.
Meepo
* Winter's Curse in late game is pretty much the end for Meepo or any of his nearby allies. Natural counter for Winter's Curse like 
Linken's Sphere or 
Lotus Orb is meaningless to her if she can land it on one of your clones.
Additional:
* Meepo's clones usually gets grouped in teamfight making any of them ideal target for Winter's Curse, forcing Meepo to literally kill himself. Also unlike another hero he cannot protect himself with Linken's Sphere.
Earthshaker
[wiki] rating: 2.0 (winrate: 49% pickrate: 12%)Chaos Knight
* Echo Slam's damage potential increases due to Chaos Knight's 
Phantasm illusions.
Additional:
*

Aftershock will always slow down your illusions, since they can't have spell immunity.
Meepo
* Echo Slam's damage potential increases due to Meepo's clones.
* Eathshaker's AoE stuns can interrupt Meepo's 
Poof cast animation.
Additional:
* Echo Slam deals catastrophic damage against a cluster of Meepos and anyone nearby.
* He can potentially stunlock any number of Meepos for a fairly long duration, often enough to finish one off.
Lich
[wiki] rating: 2.0 (winrate: 48% pickrate: 10%)Chaos Knight
* Chain Frost can eliminate Chaos Knight's Phantasm army, especially after he clumped up using 
Reality Rift.
* Frost Shield will heavily reduce his army's effectiveness.
Additional:
* Lich's 
Chain Frost, especially after obtaining its respective talent that provides unlimited bounces, can take out all of Chaos Knight's illusions quickly.
* An 
Aghanim's Scepter-upgraded 
Sinister Gaze can hypnotize Chaos Knight and his illusions while also draining his already low mana pool.
Meepo
* Poof combo puts all of the Meepos very close together, making them vulnerable to Frost Blast's AoE slow and multiple bounces from Chain Frost.
Timbersaw
[wiki] rating: 2.0 (winrate: 48% pickrate: 8%)Chaos Knight
* 
Reactive Armor helps Timbersaw to endure the damage from 
Chaos Bolt and Reality Rift combo.
* Timbersaw's large amount of pure damage AoE nukes clears Chaos Knight's illusions quickly, drastically reducing his damage.
Additional:
* Strong area damage, particularly from 
Whirling Death and 
Chakram, lets Timbersaw clear out illusions quickly.
* Whirling Death directly reduces Strength from both Chaos Knight and his Phantasm illusions, reducing both the damage output and raw health that the hero relies on.
* Reactive Armor quickly builds stacks against Phantasm illusions, making Timbersaw hard to kill.
* 
Timber Chain allows Timbersaw to escape while surrounded.
Meepo
* Because multiple Meepos tend to clump up, they present an easy target for Timbersaw's many area abilities.
* Although be careful since Timbersaw cannot use Timber Chain to escape if rooted from 
Earthbind.
Bristleback
[wiki] rating: 2.0 (winrate: 46% pickrate: 8%)Chaos Knight
* Quill Spray quickly destroys Chaos Knight's Phantasms.
Meepo

Kunkka
[wiki] rating: 2.0 (winrate: 44% pickrate: 3%)Chaos Knight
* Tidebringer, Torrent and Ghostship destroys Chaos Knight's Phantasm army all through the game.
Meepo
* X Marks the Spot is good to prevent a single meepo from escaping from a deadly situation.
* Tidebringer, Torrent and Ghostship destroys Meepo's clones.
Additional:
* 
Tidebringer's cleave damage can wear down Meepo's clones quickly. It can also give Meepo problems in the lane, due to his melee range and initially low health pool.
* 
Ghostship and 
Torrent can effectively disable Meepo while dealing heavy damage.
* 
X Marks the Spot prevents attempts to escape using Poof.
Sven
[wiki] rating: 2.0 (winrate: 43% pickrate: 1%)Chaos Knight
* Great Cleave is very effective against Chaos Knight's illusions.
* Storm Hammer's radius can catch all of Chaos Knight's illusions at once, especially after Reality Rift.
* Warcry shields Sven and his teammates against Chaos Knight's burst physical damage.
Additional:
* 
Storm Hammer's faster projectile speed and cast time allows Sven to stun Chaos Knight and his illusions before he can cast Chaos Bolt.
* 
Warcry's armor bonus counteracts Reality Rift's debuff and reduces Chaos Knight's damage output.
* 
Great Cleave and 
God's Strength devastates Phantasm illusions.
Meepo
* Great Cleave will devastate Meepo's clones. Against a closely packed group, Sven does not even need to target the clone with the lowest health.
Additional:
* Great Cleave and God's Strength can take down Meepo and his clones very quickly.
* The lack of spell immunity for Meepo's clones makes them vulnerable to Storm Hammer.
Enigma
[wiki] rating: 1.6 (winrate: 55% pickrate: 8%)Chaos Knight
* The area of effect damage from Midnight Pulse and Black Hole help deal with 
Chaos Knight's illusions.
Additional:
* 
Black Hole usually catches Chaos Knight with all his illusions.
* 
Midnight Pulse deals damage based on max health, quickly killing Phantasm illusions.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as 
Enigma, 
Invoker, 
Magnus, 
Puck, and 
Sand King.
Puck
[wiki] rating: 1.6 (winrate: 52% pickrate: 17%)Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Chaos Knight
* Puck's area of effect nukes in the form of 
Illusory Orb and 
Waning Rift clears Phantasm illusions from the early game to mid game.
* 
Phase Shift can be used to disjoint Chaos Bolt.
Dark Seer
[wiki] rating: 1.6 (winrate: 51% pickrate: 3%)Meepo
* Dark Seer can take great advantage of Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable them for him and his teammates to take out.
Chaos Knight
* Heroes that rely on illusions will suffer against Ion Shell, which kills them very quickly: 
Phantom Lancer, Chaos Knight, 
Naga Siren, 
Meepo.
* Heroes that rely on illusions typically spawn very strong illusions inside your Wall of Replica that you should use against them or their team.
Sand King
[wiki] rating: 1.6 (winrate: 51% pickrate: 10%)Chaos Knight
* Because of his massive AoE damage, Sand King is very effective against illusion heroes: Chaos Knight, Phantom Lancer, 
Terrorblade,...
Additional:
* Sand King's massive area damage output, particularly 
Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* He can apply 
Caustic Finale to illusions with attacks for extra damage.
Meepo
* Burrowstrike can stun multiple Meepos, making them vulnerable targets.
* Epicenter and Sand Storm's AoE damage ensures all Meepo clones get damaged, making it hard for Meepo to choose which one to flee as all are taking damage at the same rate.
* Just be aware when using Sand Storm to escape, as Meepo has good AoE damage and disables, which, as explained in the "Bad Against" section, works well against an invisible Sand King.
Tidehunter
[wiki] rating: 1.6 (winrate: 50% pickrate: 10%)Meepo
* Heroes who can stun multiple units at once: 
Dark Willow, 
Spirit Breaker, 
Slardar, Invoker, and 
Tidehunter.
Chaos Knight
* 
Ravage damages and disables Chaos Knight's army.
* 
Anchor Smash deals respectable area damage at early levels and lowers Chaos Knight's damage.
* 
Kraken Shell dispels Chaos Bolt and Reality Rift while providing protection from damage.
Lion
[wiki] rating: 1.6 (winrate: 50% pickrate: 17%)Meepo
* 
Finger of Death's burst damage can kill him due to his low health pool, and 
Ethereal Blade only makes it worse. If Lion purchased an Aghanim's Scepter, the situation only grows worse.
* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for 
Earth Spike & AoE 
Hex from his level 25 talent.
Chaos Knight
* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.
* Mana Drain and Hex instantly kill any illusions. Finger of Death upgraded with Aghanim's Scepter also shreds most illusions.
* One of Lion's level 20 talents lets Mana Drain affect 2 secondary targets. This can make things difficult for heroes like Phantom Lancer, Chaos Knight, and Terrorblade who rely on illusion armies.
Additional:
* 
Mana Drain is a real problem to Chaos Knight in the early game, considering his already low mana pool.
* Aghanim's Scepter upgraded Finger of Death is an AoE ability, which can deal a tremendous amount of damage to his illusions.
* Lion has two abilities that can instantly kill illusions. Provided that he does not get stunned by Chaos Bolt first, Lion can render Phantasm near-useless.
Axe
[wiki] rating: 1.6 (winrate: 47% pickrate: 8%)Meepo
* Melee heroes who rely on summons, illusions or clones will trigger Counter Helix more often, thus taking more damage: Meepo, 
Lycan, Chaos Knight, Phantom Lancer
Additional:
* The combination of 
Counter Helix and 
Berserker's Call can disable multiple Meepos and deal heavy area damage.
* Axe's natural high survivability makes it difficult to burst him down with Poof or chip away at his health with Ransack.
Chaos Knight
* Berserker's Call and Counter Helix makes short work of Chaos Knight's Phantasms.
Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions.
* Counter Helix combined with 
Blade Mail clears illusions out in no time.
Tiny
[wiki] rating: 1.6 (winrate: 45% pickrate: 5%)Chaos Knight
* Melee carries will have a hard time against Tiny's Craggy Exterior: 
Phantom Assassin, Chaos Knight, 
Juggernaut.
Meepo
* Avalanche and Toss prevents Meepo's Poof escape or using town portal scroll.
* He doesn't need to aim the weakest clone while he is grabbing tree.
Magnus
[wiki] rating: 1.6 (winrate: 44% pickrate: 4%)Chaos Knight
* Using Reality Rift sets up a 
Reverse Polarity on Chaos Knight and his illusions.
* 
Shockwave and 
Skewer kill Phantasm's illusions quickly, as can 
Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's Phantasm illusions.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Additional:
* Meepo is vulnerable to area damage and disables from Magnus himself as well as his team through Empower.
Ember Spirit
[wiki] rating: 1.4 (winrate: 47% pickrate: 9%)Meepo
* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to 
Battle Fury's cleave on multiple Meepos.
Additional:
* 
Sleight of Fist boosted by Battle Fury and 
Daedalus makes quick work of Meepo if clones are crowded around each other.
* 
Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Chaos Knight
* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.
Meepo
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, 
Ember Spirit, 
Storm Spirit, 
Nature's Prophet, Phantom Assassin, 
Riki, 
Anti-Mage, 
Weaver.
* See items and abilities disabled by roots
Dark Willow
[wiki] rating: 1.0 (winrate: 52% pickrate: 7%)Meepo
* Casting Bramble Maze on top of Meepo guarantees a root, as it is nearly impossible to leave the thorns with all of Meepo's clones.
* Terrorize and Cursed Crown offer great disables against the grouped Meepos and can prevent them from using Poof to escape.
Abaddon
[wiki] rating: 1.0 (winrate: 52% pickrate: 5%)Chaos Knight
* Abaddon could punish Chaos Knight for using his Phantasm and Reality Rift combo on him with 
Aphotic Shield. Additionally, it provides extra protection against Chaos Knight's potential to take Abaddon down quickly.
* Furthermore, Abaddon's 
Borrowed Time makes it utterly impossible to burst Abaddon down, effectively reducing the amount of targets Chaos Knight can threaten by 1 for the entire game.
Io
[wiki] rating: 1.0 (winrate: 51% pickrate: 7%)Meepo
* Tether helps Io escape from Earthbind even if Meepo has Blink Dagger.
* Io's Spirits can pressure Meepo while laning and will usually hit at least one of his clones.
Leshrac
[wiki] rating: 1.0 (winrate: 51% pickrate: 3%)Meepo
* Pulse Nova deals an insane amount of damage in an area around him, which can quickly wear down Meepo clones.
* Leshrac can catch multiple Meepos in Split Earth and follow up with the rest of his area damage spells making meepo unable to get close to leshrac.
* Diabolic Edict is a strong ability that can wear down a lone Meepo clone quickly.
Venomancer
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)Meepo
* Aggressively Poofing and Earthbinding is not going to end well against Venomancer, as he will be an easy target for 
Poison Nova.
* Venomancer's constant slows greatly reduce Meepo's mobility.
Brewmaster
[wiki] rating: 1.0 (winrate: 50% pickrate: 1%)Chaos Knight
* Storm's Dispel Magic combined with Thunder Clap deals high damage against Chaos Knight's illusions even in the late game.
* Chaos Knight's reliance on physical damage is easily hindered by Drunken Brawler.
* Chaos Knight's lack of area effect and mobility makes him easily overwhelmed by Primal Split.
Additional:
* 
Dispel Magic from {U:Storm} can instantly kill the Phantasm army early on, and can still deal a lot of damage to them late game, revealing the real Chaos Knight.
Elder Titan
[wiki] rating: 1.0 (winrate: 49% pickrate: 1%)Meepo
* Meepo lacks the disengages to escape a well-timed Echo Stomp, in particular if Elder Titan is his current target.
* Clones are counted as heroes, increasing massively the power of 
Astral Spirit's buffs, including Aghanim's Scepter's spell immunity buff.
* Meepo relies heavily on high agility and his mediocre strength gain makes him a very prized target for Natural Order.
* Meepo and his clones like to group up to hunt and kill in teamfights or ganks and can be easily disabled together with Echo Stomp.
Additional:
* 
Echo Stomp can completely disable multiple Meepos for 5 seconds.
* Astral Spirit will affect Meepo clones, as they don’t count as illusions. Elder Titan can receive a massive amount of damage, armor and movement speed from each Meepo.
* With 
Natural Order, Elder Titan’s mere existence causes Meepo to be disadvantaged, due to the aura that completely negates his base armor and magic resistance. Combining Astral Spirit with Natural Order allows Elder Titan to easily kill any Meepo within a second, depending on how much damage he gains from Astral Spirit.
* 
Earth Splitter deals over 30%/40%/50% of each Meepo’s max hp, and is even stronger if the Meepos are near Elder Titan due to Natural Order.
Pangolier
[wiki] rating: 1.0 (winrate: 49% pickrate: 12%)Chaos Knight
* Heroes who are illusion based, or even heroes who frequently build Manta Style can be cleared quickly by Pangolier's high damage, or lose their damage ouput because of Lucky Shot: Chaos Knight, Naga Siren
Meepo
* Shield Crash gains its damage reduction bonus from all Meepo clones, and can be used even when rooted, allowing Pangolier to gain a massive amount of damage reduction (even more than 100%).
* With too many clone running around during combat, it is almost impossible for Meepo to avoid Rolling Thunder or Swashbuckle.
* Still, remember that a lone Pangolier can never escape from a ganking Meepo.
Additional:
* Pangolier's arsenal deals heavy damage in a wide area, make him deadly even for a Meepo with a high magic resistance.
* 
Shield Crash can easily give him a ridiculous 90% damage resistance, resulting in a near unkillable Pangolier in a short amount of time.
* 
Rolling Thunder disrupts Meepo's initiation or escaping.
* 
Swashbuckle can hit all of Meepo clones.
* 
Lucky Shot can disarm Meepo's clones.
Meepo
* Heroes with powerful rooting abilities will disable most of Pangolier's skill, a bonus point if it pierce spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: 
Treant Protector, Meepo, 
Crystal Maiden, Dark Willow, 
Underlord, Naga Siren
Dragon Knight
[wiki] rating: 1.0 (winrate: 48% pickrate: 4%)Chaos Knight
* 
Dragon Blood's armor bonus greatly reduces the damage dealt by Phantasm.
* 
Breathe Fire and 
Elder Dragon Form's splash damage quickly destroy illusions and reduces their damage output.
Mars
[wiki] rating: 1.0 (winrate: 48% pickrate: 16%)Meepo
* 
Bulwark blocks the attack from Meepo and his clones.
* 
Spear of Mars & 
God's Rebuke prevents Meepo and his clones from initiation or escaping.
Omniknight
[wiki] rating: 1.0 (winrate: 47% pickrate: 1%)Chaos Knight
* Phantasms can be easily killed with Purification.
* Heavenly Grace dispels the stun from Chaos Bolt and the armor reduction from Reality Rift.
* Guardian Angel works well against Chaos Knight's overwhelming reliance on physical burst damage.
Additional:
* 
Purification heals a teammate targeted by Reality Rift and heavily damages Chaos Knight and his illusions in the process.
* 
Guardian Angel blocks all of Chaos Knight's damage for a duration.
Witch Doctor
[wiki] rating: 1.0 (winrate: 47% pickrate: 13%)Chaos Knight
* 
Maledict cannot be dispelled by Phantasm, and can be used to tag the real Chaos Knight hiding within his illusions.
* If Witch Doctor has an Aghanim's Scepter, 
Death Ward will bounce between Chaos Knight's illusions, destroying them quickly.
* However, Death Ward is easily interrupted by Chaos Bolt until Witch Doctor buys 
Glimmer Cape or 
Black King Bar.
Shadow Fiend
[wiki] rating: 1.0 (winrate: 46% pickrate: 18%)Meepo
* Shadow Fiend can easily focus down and kill one of the Meepos.
* The amount of damage from Shadow Fiend's AoE spells makes Meepo vulnerable in every aspect.
Lina
[wiki] rating: 1.0 (winrate: 46% pickrate: 9%)Meepo
* Light Strike Array catches Meepo and his clones if he tried to gank Lina with Earthbind & Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
Medusa
[wiki] rating: 1.0 (winrate: 45% pickrate: 2%)Meepo
* Poof won't damage Medusa and he can Gaze an entire flock of Meepos.
* Mystic Snake will easily become the bane of Meepo early game.
Outworld Destroyer
[wiki] rating: 0.6 (winrate: 51% pickrate: 13%)Chaos Knight
* Illusion based heroes (like Chaos Knight and Terrorblade) can't use their illusion beneficially against Sanity's Eclipse's high AoE burst damage.
Underlord
[wiki] rating: 0.6 (winrate: 51% pickrate: 7%)Meepo
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: 
Sven, 
Tiny, 
Wraith King, 
Dragon Knight, Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.
Windranger
[wiki] rating: 0.6 (winrate: 51% pickrate: 16%)Chaos Knight
* As long as Windranger is able to identify the real hero among the illusions, heroes relying on them can be easily tagged with Focus Fire: Chaos Knight, Terrorblade, Phantom Lancer, Naga Siren.
Invoker
[wiki] rating: 0.6 (winrate: 50% pickrate: 16%)Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Centaur Warrunner
[wiki] rating: 0.6 (winrate: 48% pickrate: 3%)Chaos Knight
* Heroes who are reliant on illusions: Chaos Knight, Phantom Lancer, Naga Siren.
Grimstroke
[wiki] rating: 0.6 (winrate: 47% pickrate: 12%)Chaos Knight
* Heroes who are reliant on illusions or summons: Chaos Knight, 
Broodmother, Naga Siren.
Batrider
[wiki] rating: 0.6 (winrate: 47% pickrate: 1%)Meepo
* 
Batrider's Flaming Lasso can become annoying when Batrider has a team nearby to kill the disabled Meepo. His Firefly is also good AoE damage, which when stacked with sticky napalm (which is AoE too and can hit all Meepos), he becomes a very formidable target.
Additional:
* Flaming Lasso is the perfect tool to isolate a single Meepo and focus him.
Pugna
[wiki] rating: 0.4 (winrate: 53% pickrate: 4%)Chaos Knight
* 
Decrepify turns the target ethereal, protecting them from Chaos Knight's and his illusions' attacks.
* 
Life Drain instantly destroys illusions. It can effectively negate Phantasm when upgraded with Aghanim's Scepter.
* 
Nether Blast quickly clears out illusions and can harass Chaos Knight in lane.
Meepo
* 
Pugna's Nether Ward doesn't really hurt Meepo since he usually buys attribute items to tank up and can be killed very quickly by 4 clones. Decrepify can amplify Poof's damage should Pugna use it to avoid Meepo's right clicking.
Bloodseeker
[wiki] rating: 0.4 (winrate: 51% pickrate: 4%)Meepo
* Every Meepo clone adds to Thirst's bonuses.
* Bloodseeker can chase down retreating clones when Meepo tries to cycle weaker clones away from combat.
Chaos Knight
* Heroes with illusion and clone abilities may confuse Bloodseeker, causing him to waste time in fights: Phantom Lancer, Chaos Knight, 
Arc Warden
Warlock
[wiki] rating: 0.4 (winrate: 50% pickrate: 4%)Meepo
* 
Fatal Bonds links the Meepos together.
Chaos Knight
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through your allies and deal with you, preventing you from doing your job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and some others.
Vengeful Spirit
[wiki] rating: 0.4 (winrate: 45% pickrate: 3%)Meepo
* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's Poof, preventing isolated Meepos from fleeing.
Chaos Knight
* Heroes who relies on illusions and summons (
Beastmaster, Chaos Knight, etc.).
Zeus
[wiki] rating: -2.0 (winrate: 46% pickrate: 8%)Chaos Knight
* Chaos Knight's high health pool makes him resistant to Zeus' burst damage. Phantasm can dispel 
Veil of Discord, a typical item purchased by Zeus.
* Zeus is easily overwhelmed by Chaos Knight's strong illusions, as Arc Lightning is not enough to kill them fast enough to have any impact.
* Zeus' low base armor makes him extremely vulnerable to Chaos Knight's high damage output and armor reduction.
Meepo
* Thundergod's Wrath strikes only the first Meepo.
* Zeus has low mobilty so consecutive Earthbinds are easy to hit and he'll quickly die from Poofs.
Ogre Magi
[wiki] rating: -2.0 (winrate: 51% pickrate: 14%)Meepo
* Ogre Magi has single-targeted magical-only damage and disables and is less effective against Meepo's clones.
Chaos Knight
* Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.
Shadow Demon
[wiki] rating: -1.6 (winrate: 47% pickrate: 2%)Chaos Knight
* Chaos Knight, 
Lone Druid, Meepo and Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Meepo
* Poof will destroy Shadow Demon's illusions created by 
Disruption and quickly escapes from 
Shadow Poison & 
Demonic Purge.
Slark
[wiki] rating: -1.6 (winrate: 48% pickrate: 13%)Chaos Knight
* 
Dark Pact is minimally effective against Phantasm illusions, and Slark lacks area damage otherwise.
* 
Pounce can be counteracted by Reality Rift.
* Slark is naturally frail and dies quickly to Chaos Knight's burst damage before he can build 
Essence Shift stacks.
* Be aware, however, that 
Shadow Dance can make Slark hard to kill as he can't be targeted during its duration.
Additional:
* Phantasms have enough health to survive Dark Pact, and Slark has no other source of AoE damage to deal with them.
Meepo
* 
Slark's Dark Pact and Pounce can deny only one Earthbind and Poof can penetrate Shadow Dance if he doesn't build Black King Bar.
Additional:
* Earthbind and Poof will still hit Slark in Shadow Dance.
* Dark Pact can only remove one Earthbind.
* 
Ransack will still affect Slark, even if he has a Black King Bar.
Wraith King
[wiki] rating: -1.6 (winrate: 51% pickrate: 17%)Chaos Knight
* Wraith King has no form of AoE to clear Chaos Knight's illusions from Phantasm.
* Wraith King is very vulnerable if he reincarnates in the middle of his illusions.
Meepo
* Meepo has a better advantage in farm with Divided We Stand, as well as having a higher attack speed due to his tendency to build items that give attributes. In addition, Wraithfire Blast stuns only one target, and choosing to engage one Meepo will most certainly mean engaging them all.
Luna
[wiki] rating: -1.6 (winrate: 51% pickrate: 7%)Meepo
* Meepo can tank Eclipse because of his clones.
* Earthbind takes away Luna's mobility advantage.
* Meepo can shutdown Luna's split-push ability with his global presence.
Chaos Knight
* Heroes that create illusions (such as 
Spectre, 
Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, 
Chen, 
Enchantress and the aforementioned Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. (However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse).
Juggernaut
[wiki] rating: -1.6 (winrate: 52% pickrate: 19%)Meepo
* Juggernaut's Omnislash is meaningless for Meepo who can share the damage across clones to save other allies.
Chaos Knight
* While Blade Fury is on cooldown, Juggernaut can easily killed by a standard Chaos Bolt & Reality Rift combo.
* Phantasm illusions can tank 
Omnislash.
Night Stalker
[wiki] rating: -1.6 (winrate: 52% pickrate: 5%)Meepo
* 
Night Stalker's most skills are single targeted which allows other Meepos to Poof, Earthbind and kill him.
Chaos Knight
* Reality Rift pulls out Night Stalker while he tries to escape or chase.
* Night Stalker doesn't have a lot of ways to deal with multiple targets, which makes him vulnerable to Phantasm illusions from early to mid game, until Night Stalker buys Aghanim's Scepter.
Arc Warden
[wiki] rating: -1.6 (winrate: 54% pickrate: 4%)Chaos Knight
* Chaos Knight can dispel Flux with Phantasm.
* Chaos Knight can use Reality Rift to pull Arc Warden out of Magnetic Field.
* Once Chaos Knight jumps on Arc Warden with Reality Rift, Arc Warden struggles to escape due to low mobility.
Meepo
* Arc Warden's Flux is meaningless against Meepo who loves to group up. Meepo is also a very good gap closer, so Arc Warden's Magnetic Field becomes useless.
Additional:
* Flux is severely impaired against Meepo because of Divided We Stand.
* Meepo's farming speed and early powerspikes allows him to pressure Arc Warden before he is capable of fighting effectively.
* Without Black King Bar, Earthbind and Poof can finish Arc Warden quickly before he has time to do much.
Skywrath Mage
[wiki] rating: -1.2 (winrate: 50% pickrate: 6%)Chaos Knight
* Skywrath mage also has a terrible time fighting against anything that isn't a hero. As Mystic Flare only affects heroes, his skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Meepo
* 
Skywrath Mage's abilities are single targeted and he can't use Mystic Flare to its fullest potential, since all Meepos spread the damage between them. He also has no disables to prevent Meepo from Poofing to another one (unless he can get 
Ancient Seal off first).
Undying
[wiki] rating: -1.2 (winrate: 50% pickrate: 4%)Meepo
* Meepo can quickly destroy Tombstone thanks to Divided We Stand.
Chaos Knight
* Chaos Knight's multiple illusions from Phantasm can destroy Undying, as Soul Rip can't offset the damage from the high amount of damage from his illusions.
Templar Assassin
[wiki] rating: -1.2 (winrate: 51% pickrate: 5%)Meepo
* Multiple attackers thanks to summoned units or clones: Meepo, 
Witch Doctor, Lycan, Enigma, 
Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, 
Gyrocopter, 
Queen of Pain, Shadow Shaman (
Shackles), Pugna
Chaos Knight
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.

Visage
[wiki] rating: -1.2 (winrate: 54% pickrate: 1%)Chaos Knight
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.
Meepo
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.
Nature's Prophet
[wiki] rating: -1.0 (winrate: 44% pickrate: 5%)Meepo
* Meepo can net Nature's Prophet's treants with Earthbind and then Poof them, putting an end to his pushing.
* Skilled Meepos can rival and even exceed Nature's Prophet's global presence by combining Poof with 
Boots of Travel, meaning that he can not only stop his push, but also can kill him if he is not careful.
Lone Druid
[wiki] rating: -1.0 (winrate: 46% pickrate: 1%)Chaos Knight
* Reality Rift lets Chaos Knight bypass the Spirit Bear and jump onto Lone Druid.
* The Spirit Bear's lack of scaling means it dies quickly to Chaos Knight during the late-game.
Rubick
[wiki] rating: -1.0 (winrate: 46% pickrate: 16%)Chaos Knight
* While Chaos Knight can land far away from Rubick due to 
Telekinesis, it can be counteracted by Reality Rift.
* Phantasm dispels 
Fade Bolt's damage reduction debuff.
* Rubick is fragile and can easily be killed by Chaos Knight and Phantasm's illusions, before he retaliates.
Morphling
[wiki] rating: -1.0 (winrate: 46% pickrate: 12%)Meepo
* Earthbind disables Waveform, effectively keeping Morphling in place for an extended period of time, allowing Meepo to deal considerable damage with Poof.
Queen of Pain
[wiki] rating: -1.0 (winrate: 47% pickrate: 9%)Meepo
* Meepo is the hard counter for Queen of Pain - chain of Earthbinds prevents her from using Blink for a long time, and without any other escape options, Queen of Pain cannot survive several Poofs and attacks.
* Meepo tends to build items with attributes, mitigating Queen of Pain's magical burst.
Additional:
* Chain of Earthbinds prevents her from using 
Blink, allowing Meepo to quickly kill her with Poof and attacks.
* Meepo tends to buy items with attributes, mitigating Queen of Pain's magical burst.
Spectre
[wiki] rating: -1.0 (winrate: 47% pickrate: 3%)Meepo
* Poof combined with Earthbind can be used to easily lockdown and burst Spectre down.
* As Meepo's playstyle is often to come online early to mid game and take over the whole game, Meepo will often be much further ahead of Spectre in farming.
* Meepo's global map presence allows him to effectively hunt for Spectre and disrupt her farm.
* Spectre has no strong AOE abilities or way to control or lock down Meepo.
Drow Ranger
[wiki] rating: -1.0 (winrate: 47% pickrate: 4%)Chaos Knight
* Reality Rift will disable Drow Ranger's Marksmanship, along with Chaos Bolt he can keep her locked for enough time to be killed.
* Phantasm's illusions are hard for Drow Ranger to deal with as she lacks of AoE damage.
Riki
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Meepo
* Root is a deadly threat to Riki, disabling both Blink Strike and Tricks of the Trade while making him fully revealed, making Earthbind a good ability against him.
* Smoke Screen may not be able to silence all the Meepo clones.
* Riki has no true area damage, as Tricks of the Trade's damage is distributed between all Meepo clones, so he cannot effectively fight Meepo or deal with his strong ability to push.
Lifestealer
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Meepo
* 
Lifestealer is not affected by Earthbind or Poof during 
Rage, making him a difficult target to work around.
Meepo
* Lifestealer's Rage and Open wounds become useless when Meepo has 4 or more clones, as Ransack will heal Meepo too quickly for Lifestealer to take down.
Chaos Knight
* Chaos Knight's Level 20 Talent: Reality Rift Pierces Spell Immunity allows for quick bursting down of Lifestealer during his Rage.
* Phantasm dispels Open Wounds.
* Lifestealer has no way of dealing with Chaos Knight's illusions.
Storm Spirit
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Meepo
* Earthbind, like any root, inhibits usage of 
Ball Lightning, eliminating Storm Spirit's mobility.
Silencer
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Chaos Knight
* Casting Phantasm before a fight minimizes the disruption from 
Global Silence.
* Because Chaos Knight generally relies on attack damage, Silencer's spells won't be as effective against him.
Necrophos
[wiki] rating: -1.0 (winrate: 50% pickrate: 3%)Chaos Knight
* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like Chaos Knight, 
Centaur Warrunner or Magnus are good targets for his ultimate.
Meepo
* Necrophos struggles at clearing away durable illusions or summons. Meepo can overwhelm Necrophos with his many duplicates, especially in the later stages of the game, and his Earthbind will prevent Necrophos from getting away, even if he casts Ghost Shroud.
* Meepo's high burst damage from {Ability ID:Poof|Meepo} and {Item ID:Ethereal Blade} can make it difficult for to Necrophos to stay alive, and as Necrophos excels in extended fights, he will not be able to do as much damage as he intends to.
Chaos Knight
* Illusions make it difficult for Necrophos to target his Reaper's Scythe correctly, thus giving illusion heroes like Chaos Knight or Naga Siren an edge against Necrophos.
Mirana
[wiki] rating: -1.0 (winrate: 51% pickrate: 16%)Meepo
* Earthbind prevents Mirana from Leaping or going invisible with Moonlight Shadow. She can be easily killed by Poof and Ransack while disabled.
* Landing a Sacred Arrow on Meepo does not render him helpless, as all of the other Meepos can still fight back.
Bounty Hunter
[wiki] rating: -1.0 (winrate: 54% pickrate: 10%)Chaos Knight
* Phantasm dispels 
Track, and the illusions make it difficult to Track the real Chaos Knight.
* Bounty Hunter is fragile and can easily be killed by Chaos Knight and Phantasm's illusions.
Razor
[wiki] rating: -1.0 (winrate: 54% pickrate: 6%)Chaos Knight
* Razor has no way to deal with Chaos Knight's multiple illusions from Phantasm.
Keeper of the Light
[wiki] rating: -0.6 (winrate: 45% pickrate: 4%)Meepo
* Heroes that can jump and kill him: Meepo, 
Clinkz, 
Templar Assassin
Earth Spirit
[wiki] rating: -0.6 (winrate: 48% pickrate: 10%)Meepo
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: Earth Spirit, Ember Spirit, Storm Spirit, Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots
Disruptor
[wiki] rating: -0.6 (winrate: 49% pickrate: 9%)Chaos Knight
* Chaos Knight with Phantasm
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with 
Tricks of the Trade
* Phantom Lancer with 
Doppelganger
* Ember Spirit with Sleight of Fist and 
Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with 
Mirror Image
* 
Tusk with 
Snowball
* Juggernaut with Omnislash
* 
Brewmaster with 
Primal Split
* Lifestealer with 
Infest
* 
Phoenix with 
Supernova
Additional:
* Phantasm removes 
Glimpse and dispels 
Thunder Strike. Additionally, the Phantasm illusions make it difficult to use Glimpse and Thunder Strike on the real Chaos Knight.
* Disruptor's lack of mobility, combined with his lack of innate defense, sets him up for a Reality Rift and a beatdown by Chaos Knight and his illusions.
Weaver
[wiki] rating: -0.6 (winrate: 51% pickrate: 13%)Meepo
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: Earth Spirit, Ember Spirit, Storm Spirit, Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots
Ursa
[wiki] rating: -0.6 (winrate: 51% pickrate: 16%)Chaos Knight
* Ursa struggles against illusion heroes like Chaos Knight and Phantom Lancer.
Additional:
* Ursa cannot effectively fight against Phantasm's illusions with his single-target damage.
* Chaos Bolt's potentially long stun with Chaos Bolt gives Ursa little opportunity to 
Enrage.
Shadow Shaman
[wiki] rating: -0.6 (winrate: 52% pickrate: 16%)Chaos Knight
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: 
Bane, Beastmaster, 
Bloodseeker, 
Clockwerk, Doom, Shadow Shaman.
Chen
[wiki] rating: -0.6 (winrate: 52% pickrate: 0%)Chaos Knight
* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, 
Visage. However, Chen can convert enemy summons with Holy Persuasion, as long as they don't bunch up.
Huskar
[wiki] rating: -0.6 (winrate: 52% pickrate: 3%)Chaos Knight
* Heroes with illusions can overwhelm Huskar, as he has no AoE abilities: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Enchantress
[wiki] rating: -0.4 (winrate: 46% pickrate: 1%)Meepo
* Enchantress's 
Untouchable slows down Meepos attacks and 
Impetus can deal heavy pure damage to a single Meepo, however once Meepo has closed the gap she is an easy target for Poof.
Meepo
* Meepo can quickly kill Enchantress with a Poof combo, rendering Untouchable useless.
Pudge
[wiki] rating: -0.4 (winrate: 46% pickrate: 19%)Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, 
Pudge and Clockwerk.
Chaos Knight
* Phantasm's illusions make it difficult to land 
Meat Hook and 
Dismember.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Dismember.
* Chaos Strike's lifesteal offsets 
Rot's damage.
Legion Commander
[wiki] rating: -0.4 (winrate: 47% pickrate: 11%)Chaos Knight
* Heroes who rely on illusions will see them destroyed easily by Overwhelming Odds: Phantom Lancer, Chaos Knight, Terrorblade, Naga Siren
Meepo
* When Legion Commander uses 
Duel on one Meepo, he can use his other Meepos to kill her. If he wasn't dueled, he can help the teammate who was duelled to give the teammate the damage instead of Legion Commander.
* However, if Legion Commander picked up an Aghanim's Scepter and she duels one Meepo, that might be the end of Meepo if Legion managed to gather enough damage from previous duels.
Phoenix
[wiki] rating: -0.4 (winrate: 50% pickrate: 9%)Chaos Knight
* Illusion-based heroes such as Naga Siren or Chaos Knight are vulnerable to Phoenix's DPS and attack speed slow, as their illusions, no matter how many, will be unable to deal enough damage to actually be a threat, and they will all be completely useless against the Supernova.
Meepo
* Meepo is unlike any other multi-unit enemy Phoenix may face in the battlefield. Unlike illusion-based heroes like Phantom Lancer or Chaos Knight, Meepo's clones are not illusions, meaning they can deal full damage to the Phoenix Sun if all four (or five) are present.
Additional:
* Earthbind can prevent Phoenix from using 
Icarus Dive, the only escaping mechanism of this hero.
* Heavy burst damage from Poof can easily kill Phoenix even when it slows down all the Meepos with 
Fire Spirits.
* Meepo's clones destroy the Phoenix Sun from Supernova in no time, even when they are slowed down by Fire Spirits.
* Meepo's naturally high magic resistance gives Phoenix a hard time with bursting him down. He can even turn the tide if Icarus Dive is on cooldown.
Void Spirit
[wiki] rating: -0.4 (winrate: 50% pickrate: 13%)Meepo
* 
Void Spirit can dodge Earthbind with 
Dissimilate and 
Astral Step, giving him a good chance to escape. If he gets caught anyways, 
Resonant Pulse allows him to retaliate.
Meepo
* Meepo's Earthbind can easily lockdown Void Spirit.
* Meepo and his clones can easily burst Void Spirit's Resonant Pulse.
Slardar
[wiki] rating: -0.4 (winrate: 50% pickrate: 5%)Meepo
* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.
Meepo
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's Earthbind will root Slardar, making him unable to chase/escape for the time being. Also, Poof's low cooldown and high damage can burst Slardar down rather quickly.
Spirit Breaker
[wiki] rating: -0.4 (winrate: 51% pickrate: 8%)Meepo
* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.
Meepo
* Earthbind's root prevents/interrupts Charge of Darkness.
* As a single target focused hero without much damage output, Spirit Breaker is ineffective in general against Meepo. Consider upgrading Nether Strike with Aghanim's Scepter to spam AoE stuns against Meepo clones.
Additional:
* Spirit Breaker heavily relies on disabling one enemy at a time therefore rendering him useless against five Meepos at once.
Troll Warlord
[wiki] rating: -0.4 (winrate: 52% pickrate: 12%)Meepo
* 
Troll Warlord can root and deal a lot of damage to a single Meepo while lifestealing through the assault from the other Meepos. Meepo needs expensive items like Ethereal Blade or 
Heaven's Halberd to be able to fight him.
Chaos Knight
* Chaos Knight's tanky illusions easily take advantage of Troll Warlord's lack of AoE damage.
* Chaos Bolt can stun Troll for up to 4 seconds and Reality Rift prevents Troll Warlord from chasing down foes.
* Phantasm increases Chaos Knight's physical damage output up to 4 times and can easily kill Troll Warlord before he has a chance to use Battle Trance or a Black King Bar.
Broodmother
[wiki] rating: -0.4 (winrate: 53% pickrate: 2%)Chaos Knight
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother
Meepo
* Earthbind prevents Broodmother from escaping Meepo's attacks.
* Poof will quickly clear any nearby spiders.
* Broodmother wants to pick off single target heroes. With Meepo's Divided We Stand, it gets a lot harder once every Meepo Poofs in.
Phantom Assassin
[wiki] rating: -0.2 (winrate: 45% pickrate: 16%)Meepo
* 
Phantom Strike allows Phantom Assassin to jump on his clones.
* Meepo's low health pool can burst down by 
Coup de Grace critical strike.
Chaos Knight
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them: Broodmother, Phantom Lancer, Chaos Knight.
Meepo
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: Earth Spirit, Ember Spirit, Storm Spirit, Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, Weaver.
* See items and abilities disabled by roots
Tinker
[wiki] rating: -0.2 (winrate: 54% pickrate: 12%)Chaos Knight
* With Aghanim's Scepter, Tinker's Laser completely stops Chaos Knight's damage, forcing him to buy either a Black King Bar for his own survivability while leaving his illusions still vulnerable, or a Monkey King Bar leaving him still vulnerable to Tinker's nukes, though improving his damage.
* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.
Additional:
* Tinker's Aghanim's Scepter upgraded 
Laser can blind him and all of his Phantasm illusions.
Meepo
* 
Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
Chaos Knight
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, 
Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Doom
[wiki] rating: 0.0 (winrate: 44% pickrate: 2%)Meepo
* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for a prolonged 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Chaos Knight
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.
Snapfire
[wiki] rating: 0.0 (winrate: 46% pickrate: 5%)Chaos Knight
* Heroes reliant on illusions or summons: Broodmother, Chaos Knight, Naga Siren.
Meepo
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during 
Mortimer Kisses and dodge the projectiles easily due to their slow speed.
* Heroes with mobility spells (such as Queen of Pain's Blink and Clockwerk with 
Hookshot) can easily avoid 
Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
Viper
[wiki] rating: 0.0 (winrate: 47% pickrate: 6%)Meepo
* 
Nethertoxin prevents the lifesteal from Ransack. The silence from Viper's level 25 talent also prevents Meepo escaping with Poof.
* Meepo and his clones have a lack of magic resistance, so they're vulnerable to 
Poison Attack & 
Viper Strike directed onto one clone.
Chaos Knight
* Viper has no response to the standard initiation combo of Reality Rift into Chaos Bolt.
* Phantasm can eliminate Viper almost instantly with its damage output.
Additional:
* As Viper focuses on single-target damage, he has trouble fighting off Phantasm illusions.
* Reality Rift counteracts Viper's slows and reduces his durability.
Techies
[wiki] rating: 0.0 (winrate: 48% pickrate: 8%)Meepo
* Due to the nature of Divided We Stand and the playstyle of splitting up multiple Meepos across the map, Techies can limit Meepo's movement with mines forcing the Meepo player to either keep all Meepos together or be extra careful when moving each individual Meepo because clones cannot carry any True Sight-providing item.
* However, if a mine blast isn't enough to kill a Meepo, he can Poof to safety of another Meepo.
Additional:
* 
Stasis Trap can lock multiple Meepos in place and prevent them from Poofing.
* 
Proximity Mines, 
Remote Mines and 
Blast Off! can deal heavy magic damage to multiple Meepos.
Chaos Knight
* Phantasm's illusions can be used to push towers and force Techies to detonate Remote Mines.
* Phantasm's illusions can be used to sweep Proximity Mines and Stasis Traps.
* Chaos Knight can easily kill a lone Techies before they Blast Off!.
Anti-Mage
[wiki] rating: 0.0 (winrate: 49% pickrate: 13%)Chaos Knight
* Anti-Mage commonly builds Battle Fury, which can deal with Phantasm illusions easily.
* 
Counterspell, if timed right, will turn Chaos Bolt against the Knight, and can set up for a kill if he is not careful.
* Even if Counterspell is on cooldown, 
Blink can almost always dodge a Chaos Bolt because of its slow projectile.
* 
Mana Break will quickly drain Chaos Knight's mana.
Meepo
* Multiple Earthbinds allows Meepo to lock down Anti-Mage almost indefinitely.
* Meepo's clones can only use their mana for Poof, keeping their mana pool nearly full and thus making them a bad target for a Mana Void.
Additional:
* Earthbind can prevent Anti-Mage from using Blink, allowing Meepo to kill him with attacks and Ransack.
Crystal Maiden
[wiki] rating: 0.0 (winrate: 49% pickrate: 14%)Chaos Knight
* Heroes the make heavy use of illusions, like Chaos Knight, Phantom Lancer, or Spectre can suffer from Crystal Maiden, as Freezing Field can quickly kill off the entire horde if not stopped.
Chaos Knight
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: 
Drow Ranger, Bane, 
Necrophos, Crystal Maiden.
Phantom Lancer
[wiki] rating: 0.0 (winrate: 51% pickrate: 10%)Chaos Knight
* Chaos Knight's single target abilities are difficult to target against Phantom Lancer's illusions.
* Chaos Knight's lack of mobility makes him an easy target for Phantom Lancer to 
Phantom Rush and drain his already low mana pool.
Additional:
* 
Juxtapose allows Phantom Lancer to overwhelm Chaos Knight due to his single-target abilities.
* Doppelganger can be used to dodge Chaos Bolt.
* 
Spirit Lance can be used to harass Chaos Knight during the early game.
* Since Phantom Lancer builds 
Diffusal Blade often, it can quickly drain Chaos Knight of all his mana, leaving him unable to cast spells.
Meepo
* Poof from multiple Meepos will destroy illusions quickly.
* Earthbind's area root can catch Phantom Lancer in a group of illusions and prevent him from using Doppelganger for a long time.
Additional:
* Poof will destroy Phantom Lancer's illusions within a short time.
* Earthbind prevents Phantom Lancer from using Doppelganger.
Clockwerk
[wiki] rating: 0.0 (winrate: 52% pickrate: 7%)Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Chaos Knight
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.
Beastmaster
[wiki] rating: 0.0 (winrate: 53% pickrate: 6%)Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Chaos Knight
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, Beastmaster, Bloodseeker, Clockwerk, Doom, Shadow Shaman.
Naga Siren
[wiki] rating: 0.0 (winrate: 54% pickrate: 2%)Chaos Knight
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother
Meepo
* A good Meepo can mess up Naga Siren entirely: His Earthbind is AoE, which can bind her illusions, his Poof is a powerful AoE nuke and will clear her illusions. He is also 2/3/4 Meepos, not one, so her Ensnare will not work efficiently while escaping from him.
Bane
[wiki] rating: 0.0 (winrate: 54% pickrate: 3%)Meepo
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, 
Faceless Void, Gyrocopter, Juggernaut, 
Luna, Meepo, 
Mirana, 
Monkey King, 
Morphling, Phantom Assassin, Phantom Lancer, Riki, 
Shadow Fiend, Slark, 
Sniper, Terrorblade, Troll Warlord, Weaver.
Chaos Knight
* Heroes with illusions and summons can swarm Bane, who has no area abilities: Broodmother, Chaos Knight, Nature's Prophet, Phantom Lancer, Terrorblade
Additional:
* Phantasm's illusions make it difficult for Bane to target Chaos Knight with 
Nightmare, 
Brain Sap and 
Fiend's Grip.
* Chaos Bolt is a comparatively low cooldown tool to interrupt Fiend's Grip.
* Nightmare can be transferred by Phantasm illusions.
Meepo
* All of Jakiro's skills are Area of Effect, which can easily affect all Meepos in a targeted area.
Chaos Knight
* With his AoE damage, Jakiro can easily kill Chaos Knight's
Phantasm illusions.
Black King Bar, making him vulnerable to an Ice Path into Macropyre combination.
Ice Path and 
Macropyre punish Reality Rift with a long stun and heavy damage across all illusions.
* Chaos Knight usually doesn't buy a
Additional:
*
