* Venomancer's damage-over-time abilities do little damage against Counterspell.
* Blink helps Anti-Mage get away from Venomancer's slows.
Additional:
* Counterspell provides magic resistance, diminishing the effectiveness of Venomancer's spells.
* Venomancer's lack of hard disable allows Anti-Mage to use Blink, circumventing the slows Venomancer depends on.

* Enigma's Midnight Pulse damage can be substantially mitigated by Anti-Mage's high magic resistance thanks to Counterspell.
* In the early game, Anti-Mage's Mana Void can cancel a Black Hole until Enigma gets his Black King Bar.
* Should Anti-Mage survive a Black Hole combo, Enigma will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.

* 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.

* Borrowed Time & Aphotic Shield can dispel Venomous Gale and Poison Sting.

* Walrus PUNCH! interrupts Black Hole and it pierces spell immunity.

* Snowball can be used to save allies or him during Venomous Gale and Poison Nova.
* Venomancer has lack of mobility and low base health can killed by Warlus Punch.

* 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.

* While Reincarnation is off cooldown, Venomancer abilities can't kill Wraith King easier.
* Vampiric Aura can out-heal the slow {tooltip:DoT|Damage over Time} from Poison Sting.

* Everything Enigma has is something Rubick will like:
* Malefice helps with interrupting channeling spells in case Telekinesis is off cooldown.
* Demonic Conversion helps with pushing or counter-pushing a lane.
* Midnight Pulse is great for blocking off areas or just doing steady damage in teamfights.
* Black Hole is one of the best spells for teamfights, and could easily turn a losing one around.
* Black Hole also requires channeling, making it an easy steal for Rubick because he usually stays back in a teamfight, making it hard to catch him with Black Hole.
* Telekinesis can break Enigma's Black Hole fairly easily.
* Fade Bolt counters early push strategy of Enigma's waves of Eidolons.
* Spell Steal pierces spell immunity, so Enigma can't prevent Rubick from stealing Black Hole by activating Black King Bar.
Additional:
* Telekinesis has a longer range than the AoE of Black Hole for the purposes of cancelling it.
* All of Enigma's spells are useful to Spell Steal.
* Malefice is useful for interrupting channeling spells or long cast animations.
* Demonic Conversion can be used to push or counter-push a lane.
* Midnight Pulse is useful to block an area or for team fights.
* Black Hole is very easy to steal, as it is a channeled ability. It's also one of the best ultimate abilities for team fights, and it can easily turn the fight around for the enemy team.

* All of Venomancer's abilities are decent choices for Rubick's Spell Steal. Stealing Plague wards makes them apply Poison sting as well.

* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.

* 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.

* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.

* 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.

* 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.

* Venomancer has low health, which makes him vulnerable to Lina's heavy magic damage.
* Fiery Soul attack speed bonus removes Plague Wards easily in all stages of the game.

* Dark Pact can dispel Venomous Gale and Poison Sting.
* Shadow Dance allows Slark heightened regeneration when out of vision making DoTs effects less threatening.

* 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.

* 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.

* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.

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

* Heroes with damage-over-time abilities will not only proc Bristleback's passive continuously, they will also do little harm to him when he is facing away from the source: Venomancer, Arc Warden

* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.

* 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.

* 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.

* Deals damage over time: Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom
* The nature of some abilities turn them into an easy target for a turnover from Spiked Carapace:
* Slow-moving projectiles: Skywrath Mage, Tinker, Necrophos
* Large area-of-effect with delay or require channeling: Enigma, Crystal Maiden, Invoker, Shadow Fiend, Pugna, Keeper of the Light
* Deals damage over time: Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom

* Dark Rift allows Underlord to transport allies from poison damage-over-time to the fountain.
* Underlord usually buys Pipe of Insight that gives a magic resistance to allies, inhibiting the damage from Venomancer abilities.

* 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

* Venomancer is a low health hero and low range distance attack hero easily to harass putting Ion Shell in a distance creep enemy in early game .
* Venomancer depends entirely on all his slows poison skills to keep distance or chasing enemy heroes, but Surge ignores slows, so is nearly impossible hunt or run away of Dark Seer or his surged teammates.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* Reflection illusion will apply Poison Sting to you if hit.
* Conjure Image and Metamorphosis will make quick work of your Plague Wards.
* While ticking down from your poison, Terrorblade can wait until the last possible moment to Sunder a target, either friend or foe.

* 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.

* Voodoo Restoration heals to counter damage over time of Poison Nova and Poison Sting.

* 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.

* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.

* In the laning stage, making illusions of Venomancer will turn his Poison Sting back at him, making for an easy gank level one, and for later when your mid comes for ganks.

* Doom pierces spell immunity and can prevent Enigma from casting any spells or using items until the duration of the spell depletes, as well as damaging him over time. This can however, be blocked by a Linken's Sphere.
* An Enigma with a Helm of the Dominator can potentially feed his dominated creeps to Doom's Devour, giving Doom the abilities and benefits instead.

* Teleportation allows Natures Prophet to save himself from the damage over time of Venomous Gale, Poison Sting and Poison Nova.
* Plague Wards can be destroyed with Nature's Prophet's treants or Necronomicon.

* 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.

* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.

* 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 Devourer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* Slardar can attack through Plague Wards and gaining Bash of the Deep charges.

* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.

* 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.

* Fortune's End and False Promise easily dispel many crippling debuffs, such as Venomancer's Venomous Gale, or Skywrath Mage's Ancient Seal.

Additional:
* Fortune's End can dispel Venomous Gale and Poison Sting from allies.
* Fate's Edict grants 100% magic resistance to target, inhibiting the damage from Venomancer abilities.

* 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 abilities can mitigate Midnight Pulse's damage.

* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: Venomancer, Earth Spirit, Ogre Magi

Additional:
* Press the Attack dispels Venomous Gale and Poison Sting from Legion Commander or her teammates.

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

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