Slark
[wiki] rating: -2.0 (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.
Phantom Lancer
* Slark has no sustained AoE to fight off Phantom Lancer's illusions as they continually spawn.
* Spirit Lance can give vision of Slark by spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.

* Lifestealer has no way of dealing with Chaos Knight's illusions.
Silencer
[wiki] rating: -2.0 (winrate: 49% pickrate: 5%)Phantom Lancer
* Due to Phantom Rush and Juxtapose being passives and not affected by silence, a Phantom Lancer with a Diffusal Blade can easily kill Silencer.
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.

Night Stalker
[wiki] rating: -2.0 (winrate: 52% pickrate: 5%)Phantom Lancer
* Void's slow is dispelled by Doppelganger or counteracted by Phantom Rush.
* Spirit Lance's and Diffusal Blade's slow reduces Night Stalker's mobility and helps him or his ally escape if they're inflicted by Void or Crippling Fear.
* Night Stalker has no AoE abilites to take out Phantom Lancer's illusions. Even if Night Stalker gets an Aghanim's Scepter, there will be way too many illusions for Night Stalker to handle.
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.

[wiki] rating: -2.0 (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.
Phantom Lancer

* Phantom Lancer can also easily dodge an activated 
Spark Wraith, or use his illusions to trigger it safely.
* Phantom Rush allows Lancer to quickly close gap to get inside of Arc Warden's 
Magnetic Field.

Tempest Double will also be summoned without mana.
Additional:
* Doppelganger dispels Flux.

Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.

Beastmaster, Chaos Knight, etc.).

Undying
[wiki] rating: -1.6 (winrate: 50% pickrate: 4%)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.
Phantom Lancer
* Phantom Lancer's many illusions will easily destroy 
Tombstone, provided he has sufficient farm.
Templar Assassin
[wiki] rating: -1.6 (winrate: 51% pickrate: 5%)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.
* 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,

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).

* Battery Assault's damage is dispersed against Phantom Lancer's illusions.

Phantom Lancer
* Heroes with no AoE abilities will struggle against Phantom Lancer: 
Clinkz, Phantom Assassin, Broodmother
Skywrath Mage
[wiki] rating: -1.2 (winrate: 50% pickrate: 6%)Phantom Lancer
* 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.

Doom
[wiki] rating: -1.0 (winrate: 44% pickrate: 2%)Phantom Lancer
* Doom's Doom marks Phantom Lancer with a highly visible effect, and also silences him.

Phantom Lancer
* Phantom Lancer's illusions can make it difficult to Doom the original. Should Doom figure out the original hero, the illusions can make it difficult to cast any abilities, as their hitboxes can be used to body-block the Phantom Lancer.
* Phantom Lancer is an ideal Diffusal Blade carrier. With it, he can quite easily deplete Doom's already poor mana pool, potentially making him unable to cast his abilities to escape, retaliate or heal.
* Doom lacks any effective ability to clear waves of creeps and illusions, as the vast majority of his abilities are single-target. Without an answer, Doom may find it difficult to deal with Phantom Lancer's presence.
Medusa
[wiki] rating: -1.0 (winrate: 45% pickrate: 2%)Phantom Lancer
* Phantom Lancer with Diffusal Blade will very quickly burn Medusa's mana, making Mana Shield significantly less effective.
* Doppelganger's 1 second invulnerability can be used to dodge Medusa's petrification from Stone Gaze, as well as Mystic Snake.
* Phantom Lancer's illusions outnumber Medusa's targets from Split Shot, likely shielding your team in the process.
Lina
[wiki] rating: -1.0 (winrate: 46% pickrate: 9%)Phantom Lancer
* Doppelganger can be used to easily dodge Light Strike Array if timed correctly.
* Phantom Lancer can quickly deplete Lina's mana pool with his illusions and deal massive damage from it simultaneously since Phantom Lancer is a natural Diffusal Blade carrier.
Shadow Demon
[wiki] rating: -1.0 (winrate: 47% pickrate: 2%)Phantom Lancer
* Shadow Demon's Demonic Purge is undispellable.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:

Phantom Lancer
* Doppelganger dispels 
Soul Catcher and 
Shadow Poison.
* Demonic Purge slow is very ineffective against Phantom Rush.
* Beware that if Shadow Demon buys Aghanim's Scepter, Demonic Purge can disable Juxtapose, so check his inventory whenever possible.
* Phantom Lancer's illusions destroy 
Disruption's illusions very quickly.
Dazzle
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Phantom Lancer
* Juxtapose and Doppelganger conjures too many illusions for Dazzle to deal with, given he has no inherent movement- or AoE-abilities.
* Phantom Rush and Spirit Lance allow Phantom Lancer to trivially catch Dazzle even in the back line of a fight.
* Phantom Lancer has high base armor which counters Dazzle's physcial damage based spells in lane.
Sniper
[wiki] rating: -1.0 (winrate: 49% pickrate: 6%)Phantom Lancer
* Phantom Rush grants Phantom Lancer the mobility to close in the distance between Sniper.
* Phantom Lancer can dispel Sniper's Assassinate easily with Doppelganger and causes confusion to Sniper with the latter effect of creating an additional of 2 illusions.

Treant Protector
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Phantom Lancer
* Doppelganger can dispel Leech Seed. It can also destroy large amounts of trees, counteracting Nature's Guise and Eyes in the Forest.
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.
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.
Phantom Lancer
* Diffusal Blade is a core item on Phantom Lancer. Should it be purchased, combined with his numerous illusions, it allows him to rapidly deplete Necrophos' mana, rendering Necrophos incapable of casting anything.
* It can be difficult to single out the true Phantom Lancer among his army, giving Necrophos a hard time with aiming his ultimate.
* Even if his illusions are defeated, Phantom Lancer is capable of creating more at his disposal with almost no issues.
Tusk
[wiki] rating: -1.0 (winrate: 50% pickrate: 13%)Phantom Lancer
* Doppelganger allows Phantom Lancer to dodge an incoming snowball.
* Phantom Lancer usually buys a Diffusal Blade, which is very effective against Tusk's low mana pool.

Slardar
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)Phantom Lancer
* Phantom Lancer's Doppelganger has a low cooldown and applies a basic dispel on PL, making it hard to keep Corrosive Haze on him.
* Phantom Lancer usually purchases Manta Style which provides another basic dispel to remove Corrosive Haze with.
* Besides Slithereen Crush, Slardar does not have another way to deal with illusions and has a low mana pool, which allows Phantom Lancer with Diffusal Blade to quickly build up illusions while draining Slardar's mana.
* Phantom Rush outruns Guardian Sprint, forcing Slardar to Blink away or use Slithereen Crush defensively to avoid being killed.
Troll Warlord
[wiki] rating: -1.0 (winrate: 52% pickrate: 12%)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.

Wraith King
Warlock
[wiki] rating: -0.6 (winrate: 50% pickrate: 4%)Chaos Knight

Zeus
[wiki] rating: -0.4 (winrate: 46% pickrate: 8%)Phantom Lancer
* Heroes with global nukes will target and hit Phantom Lancer regardless of his illusions: 
Zeus
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.
Ancient Apparition
[wiki] rating: -0.4 (winrate: 52% pickrate: 10%)Phantom Lancer
* Ancient Apparition's Ice Blast will only debuff Phantom Lancer and not his illusions.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* Doom's Doom marks Phantom Lancer with a highly visible effect, and also silences him.
* Bloodseeker's Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's Ice Blast will only debuff Phantom Lancer and not his illusions.
* Grimstroke's Soulbind is undispellable.
* Shadow Demon's Demonic Purge is undispellable.
* Monkey King's Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Phantom Lancer
* Phantom Lancer can dispel or escape from Cold Feet with Doppelganger and Phantom Rush, respectively. Phantom Lancer also frequently builds a Manta Style which dispels Cold Feet.
* Ancient Apparition has trouble dealing with Phantom Lancer's illusions due to a lack of Area of Effect damage other than Ice Blast.
* Phantom Lancer tends to build a Diffusal Blade, which greatly amplifies his damage against Ancient Apparition due to Ancient Apparition's high mana pool.
* Ancient Apparition has no escape/mobility mechanisms, making him an easy target for Phantom Lancer at any stage of the game.
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.
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.

Storm Surge gives Razor's high mobility to chase down Phantom Lancer making Spirit Lance and Diffusal Blade slow useless.
* 
Eye of the Storm along with Aghanim's Scepter can quickly reduce Phantom Lancer's armor.
