* Black Hole requires channelling, making it easy to be interrupted with Hookshot.
* Enigma lacks mobility without a Blink Dagger and also is squishy, making him fall easily when ganked by Clockwerk.
Additional:
* Hookshot's stun pierces through spell immunity and Enigma's channeling can be easily cancelled from a safe distance, assuming none of his allies are in the way.
* Enigma lacks mobility without Blink Dagger or Force Staff. Clockwerk can stay atop Enigma using Battery Assault and isolate him with Power Cogs, and potentially track him down with Rocket Flare.

* Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
* Power Cogs and Battery Assault keep Drow Ranger from escaping.
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.
Additional:
* Getting trapped in Power Cogs usually means the end for Drow Ranger.

* Walrus PUNCH! can interrupt Black Hole and it can pierce spell immunity.
* In pretty much any phase of the game, Tusk's abilities can easily cancel Black Hole and disrupt Enigma's positioning.

* Snowball and Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.
* Tag Team allows Tusk to slow her down and land a killing blow on her.
* Walrus PUNCH! slows Drow Ranger and deals a huge amount of damage to her.

* Take Aim allows Sniper to outrange Drow Ranger and deal damage at her without much fear of retaliation
* Sniper can slow down Drow Ranger with Shrapnel, and both Shrapnel and Assassinate makes it easier for Sniper's team to track and take her down
Additional:
* Somewhat like Medusa, Drow Ranger is a fairly immobile hero that hopes to be able to attack without dying. Sniper should outrange her.
* Shrapnel and Assassinate provides vision over her, and slows her down, making it easier for you team to focus on taking her down
* Be careful however that if she starts attacking you, she packs a bigger punch than you thanks to Marksmanship.

* Sniper has a very long range, so it is rare that Enigma can catch him in a Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with the level 20 talent.
* Enigma's Eidolons from Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with Maelstrom/Mjollnir.
Additional:
* Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small Black Hole AoE. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation, assuming Enigma does not have Aeon Disk.

* Spectre can easily close the distance on Drow Ranger with Haunt and stick on her with Spectral Dagger, negating the bonus agility from Marksmanship.

* Haunt can ruin Enigma's initiation with Blink Dagger, no matter where he is on the map.
* Dispersion reflects the damage of Midnight Pulse and Black Hole inflicted back to Enigma.

* Nyx Assassin has a lot of burst damage from his Impale, Mana Burn, Dagon, and the bonus damage from Vendetta. All of this damage is enough to kill Drow Ranger.
* Nyx Assassin is usually invisible most of the time thanks to his ability Vendetta, which allows him to gank Drow Ranger easily.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Puck, Slark, Nyx Assassin, etc.

Additional:
* Enigma's uncontrollable damage from Malefice and Midnight Pulse make him easy to stun with Spiked Carapace.
* Black Hole can be easily interrupted by Impale or Spiked Carapace.

* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole.
* Fatal Bonds can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team.
* Warlock's Upheaval can interfere with Enigma's initiation and potential follow-ups thanks to its large AoE.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere Warlock will always be able to cancel channeling of Black Hole.
* Enemies often get clumped up around Black Hole giving Warlock a perfect opportunity to cast Fatal Bonds and Upheaval on multiple enemies.

* While heroes with strong mobility able to get close/flee or long range disables do well against him, heroes with no escaping abilities/lacking long disables will perish against Warlock. Once the {U:Warlock Golem} lands with its stun, its hardly possible to escape when he casts Upheaval. Just watch your pet burn the enemies as they try running away or blow their strongest abilities to stop your {U:Warlock Golem}. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.

* Lion's disables are also really effective against channeling Heroes, like Enigma or Crystal Maiden.

* Drow has a very low health pool, allowing Lion to burst her down.
* Drow has no innate escape mechanism, making her an easy target for Lion's disables.
* Lion should be wary of Drow's Gust however, as he has no natural means to deal with it.

* Blink Strike gets Riki close to Drow Ranger and disable Marksmanship.
* Smoke Screen makes Drow Ranger miss her attacks.
* Cloak and Dagger lets Riki stay close to Drow Ranger without her noticing, disabling Marksmanship.
Additional:
* With Blink Strike, Riki can get close to Drow Ranger and disable her Marksmanship, and Smoke Screen will prevent her from using Gust.

* Frail heroes who lacks mobility: Crystal Maiden, Enigma, Dark Willow, Vengeful Spirit.

Additional:
* Riki can potentially catch an Enigma out of position and prevent him from properly blinking and initiating, thanks to Cloak and Dagger used in tandem with Smoke Screen.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Puck, Slark, Nyx Assassin, etc.

* A well-timed Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* Pounce counteracts Frost Arrows' slow, letting Slark easily pin Drow Ranger down or flee.
Additional:
* Pounce and items like Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her Marksmanship bonus.
* Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.

* Heroes who build a Black King Bar (or having any sources of spell immunity) to channel abilities/items are still interrupted by Dismember: Enigma, Juggernaut, Pugna, Elder Titan.

Additional:
* Pudge can Meat Hook Enigma out of his Black Hole channeling and cancel it through Black King Bar when followed up with Dismember.
* Enigma is prone to ganks in the jungle or in the off-lane without proper vision. Pudge can take advantage of Enigma lack of mobility, assuming Enigma is not blocked by his Eidolons.
* Stacked magic resistance from his passive Flesh Heap ability can mitigate Midnight Pulse's damage.

* Meat Hook brings Drow Ranger to Pudge, disabling Marksmanship and dealing a huge amount of damage.
* Rot keeps Pudge close to Drow Ranger, continuously disabling Marksmanship.
Additional:
* Meat Hook can pull Drow Ranger to Pudge, disabling her Marksmanship.
* Following up with Dismember will prevent Drow Ranger from using Gust or Shadow Blade.

* Tidehunter's Anchor Smash decreases Drow Ranger's attack damage.

* Most summons and illusions can barely hurt Tidehunter at all, after their attacks get reduced by Anchor Smash and blocked by Kraken Shell: Nature's Prophet, Enigma
* Also Ravage's large area of effect and damage can easily damage all those units at once, or just straight up clear them.

Additional:
* Tide's Anchor Smash will cripple all of enigma's eidolons, and at a higher level tide will one shot the whole group for a boost of gold.
* Kraken Shell negates eidolons' damage and Enigma's auto attacks, making laning impossible.
* Ravage has an insane radius, and considering that you are waiting around for a blink BKB combo, the stun may catch you off guard and put blink on cooldown, limiting crucial team fight time.

* Heroes that wish to disrupt fights with spell combos or big ultimates are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* 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.

* Drow Ranger's lack of mobility makes her easy prey for Broodmother and her Spiderlings.

* Static Link zaps Drow Ranger high attack damage.
* Plasma Field & Storm Surge keeps Razor close to Drow Ranger, continuously disabling Marksmanship.

* Magnetic Field cause attacks from Drow Ranger outside to miss, forcing Drow Ranger to go inside the field, nullifying marksmanship.
Additional:
* Magnetic Field protects Arc Warden and allies from Drow Ranger's ranged attacks. She most likely will not enter the field since she will lose Marksmanship's bonus agility.
* Beware however, as Marksmanship procs will still hit since they have True Strike, so the most damaging arrows will still hit you inside Magnetic Field.

* Borrowed Time can give Abaddon a second chance after a Black Hole combo.
* Aphotic Shield can be used to save allies from a potential onslaught and dispel most negative debuffs.
* Abaddon can easily heal himself as well as his allies during a team fight.

* Like Abbadon's Borrowed Time, Reincarnation can bring Wraith King back to life, giving him a second chance to counter initiate or escape after a Black Hole combo.
* Enigma's Eidolons adds to Wraith King's Mortal Strike, increasing his Skeleton charges.

* Blood Rite can flush Enigma out of position and potentially force him to activate his spell immunity prematurely, before pulling off a Black Hole combo.
* Bloodseeker can find an Enigma out of position and Rupture him, making it difficult to initiate properly in a team fight, as it pierces through Black King Bar

* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Channeling Black Hole will render Enigma immobile, making him easy target for all of Pugna's abilities, especially Nether Blast, and Life Drain.

* Fissure does a great job at interrupting Black Hole immediately, especially with Blink Dagger and Aether Lens.
* Echo Slam's damage potential increases due to the eidolons created by Demonic Conversion.

* Phantom Rush lets Phantom Lancer get close quickly and disable Marksmanship.
* Juxtapose's illusions are hard for Drow Ranger to deal with as she has no AoE damage naturally.

* Winter's Curse, when directly targeted on Enigma, can go through Avatar, stopping Enigma's Black Hole channeling. It can also can turn his team against him, potentially killing him.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.

* Laser applies a blind debuff, making Drow Ranger miss her high damage attacks.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.

* Black Hole is a channeling ability and Earth Spirit has at least two possibilities which can interrupt these kind of spells. Enigma is exposed and cannot move while using Black Hole, thus making it easy for Earth Spirit to stop the feared ability with the huge range of Rolling Boulder and forcing Enigma to quickly rush a Black King Bar to prevent this.
* Enigma is level dependant, squishy and relativly defenseless in the early game and therefore vulnerable to aggressive roam maneuvers in this stage of the game. Earth Spirit excels at ganking, shutting down a jungling or otherwise solo farming Enigma.

* Using Ball Lightning with proper timing, Storm Spirit can protect himself from Malefice's instances, disjoint Demonic Conversion's attack projectiles, get out of Midnight Pulse's radius or even dodge a Black Hole.
* An isolated Enigma in the early game can be easily killed by Storm Spirit thanks his higher mobility and dueling potential. However, Storm Spirit can be killed when caught by Enigma's full combo, especially if Enigma has Black King Bar.
* Storm can kill all of Enigma's Eidolons relatively quickly without much risk, slowing down Enigma's farming speed, preventing him from split pushing, and giving Storm its considerable bounty, especially if Enigma chooses the Level 25 Talent that gives him more Eidelons.

* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.

* Often you can burst Drow Ranger down before she has a chance to try and Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.

* Morphling can use Waveform to close the gap between him and Drow Ranger, but should be careful of Gust and Frost Arrows.
* Morphling is a natural Manta Style carrier, which dispels the silence from Gust.

* Bristleback's tankiness can enable him to chase Enigma out of a teamfight, making it difficult to initiate with a Black Hole.

* Ezalor's Chakra Magic will drain Enigma's mana pool rather quickly and won't let him chase or initiate with Black Hole properly.
* Will-O-Wisp will disable any close caster like Enigma, forcing him have to keep his Eidolons at maximum count and keep a safe distance.
* Illuminate can wipe the pushing Eidolons in a lane with ease, diminishing Enigma's laning presence by a lot.

* Time Walk could be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void could lock down Drow Ranger with Chronosphere before she has the chance to retaliate due to her low health pool.

* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger

* Underlord can not only cancel Marksmanship's aura, but his Atrophy Aura also decreases Drow Ranger's attack damage.

Additional:
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies on agility.

* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.

* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.

* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.

* Enigma's left level 25 talent (increasing the Eidolon count from three to eleven) powers up Undying's Soul Rip.

* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

Additional:
* Vengeful Spirit can interrupt Black Hole's channeling through Black King Bar by using Nether Swap from a safe distance.
* Vengeful Spirit's Level 25 Talent can make her Magic Missile pierce spell immunity, giving her another option to use in conjunction with Nether Swap to cancel Enigma's Black Hole channeling through Black King Bar.

* Heroes with powerful channeling abilities are easily interrupted by Phantom's Embrace: Bane, Pudge, Witch Doctor, Crystal Maiden, Enigma.

* Heroes who produce many summons will have a hard time against Storm's Dispel Magic during teamfight: Broodmother, Enigma, Nature's Prophet.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Puck, Slark, Nyx Assassin, etc.

* Range-reliant heroes: Sniper, Drow Ranger

* Despite Clinkz's fragility, his harassment in the early game can be devastating; as he can kite Enigma and his Eidolons and claim their bounty.

* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.

* Without Black King Bar and if not caught in it, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons.
* If used in anticipation, Eclipse will often kill Enigma before he even gets a chance to use Black Hole to disable Luna.
* Luna has stronger laning presence than Enigma thanks to her Moon Glaives and low mana cost of her abilities, diminishing Enigma's laning presence by a lot.

* Zeus can break Blink Dagger with his long range abilities and global range ultimate, Thundergod's Wrath.
* Lightning Bolt has a long range and a mini-stun, providing a way for him to cancel Black Hole from safe distances, assuming Enigma doesn't have his Black King Bar.
* Zeus' Aghanim's Scepter upgraded ability Nimbus has a global range and mini-stun, making it an even more effective way to cancel Black Hole before Enigma initiates with Black King Bar.
* Zeus is typically able to position himself at a safe distance from the fight, making him a difficult target to capture in a Black Hole.

* Drow Ranger's low mobility and lack of defensive abilities makes her an easy gank target in the early to mid-game.
* A Dueling Drow Ranger will lose her precious Marksmanship, reduce her damage output significantly and will more likely lose that Duel.

* Silencer can easily ruin Enigma's initiation, as Global Silence cancels Black Hole, even through Black King Bar and Linken's Sphere.
Additional:
* Last Word can be cast from a long range to prevent Enigma's potential initiation.
* Global Silence can interrupt Enigma's Black Hole channeling through Black King Bar and Linken's Sphere.

* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating — and landing an effective Black Hole exceedingly difficult.
* Mystic Snake can be potentially detrimental to Enigma's initiation. Getting hit by the latter high-damage bounces (from standing behind his Eidolons or his teammates) can hinder his mana pool, preventing him from executing a strong initiation.
Additional:
* Mana Shield makes Medusa harder to kill with Enigma's Black Hole and Pulse combo.
* Medusa's Split Shot can kill Demonic Conversion creeps easier and Mystic Snake bounces off from them.
* Stone Gaze makes it hard for Enigma to approach Medusa for a Black Hole.
