* Riki can potentially catch an Enigma out of position and prevent him from properly blinking and initiating, thanks to Cloak and Dagger.
* Before Enigma gets his Black King Bar, Smoke Screen can be used to cancel Black Hole. After Enigma gets Black King Bar, Riki can also cancel Black Hole with Abyssal Blade, which is a common item built on him.
* Tricks of the Trade renders Riki hidden and invulnerable, which in combination with Abyssal Blade allows Riki to cancel Black Hole with little to no worries of getting caught in it.
* Enigma's fragility during all stages of the game makes him extremely prone to Riki's ganking.

* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot Enrage when in Smoke Screen (Black King Bar will help though).
* Even if Ursa gets vision over him, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid all Fury Swipes damage until Earthshock's slow is gone.
Additional:
* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot Enrage when caught in Smoke Screen and will miss his attacks (although Black King Bar will help with this issue).
* Even if Ursa gets vision over him and initiates with Earthshock, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.

* 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.
* Storm can zip through Black Hole stunning Enigma while he's channelling until Enigma buys Black King Bar.

* Storm Spirit can steal Aegis of the Immortal during Roshan attempts through the Pit, because of his Ball Lightning.
* Ursa has no way to catch a slippery Storm Spirit, as Earthshock's slow will do nothing to stop Storm Spirit from using Ball Lightning.

* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. But remember that Enigma can do the same to Broodmother's spiderlings with Demonic Conversion and Midnight Pulse.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, Monkey King Bar, Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Enigma, deal damage over time to Enigma and reveal Enigma if he unwittingly steps on them, disrupting his attempts to initiate with Black Hole, prevent him from using Blink Dagger, while also alerting Broodmother on his attempts to ambush her and her allies.
Additional:
* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. And Enigma can't use Demonic Summoning to instantly kill spiderlings at once.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, Monkey King Bar, Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Enigma, deal damage over time to Enigma and reveal Enigma if he unwittingly steps on them, disrupting his attempts to initiate with Black Hole, prevent him from using Blink Dagger, while also alerting Broodmother on his attempts to ambush her and her allies.

* With Aghanim's Scepter, Broodmother will gain access to Spinner's Snare, which will allow her to create invisible lines on her webs from Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, Bounty Hunter, Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, Magnus etc.

* Astral Imprisonment can save allies from a Black Hole combo. When upgraded with Aghanim's Scepter and Aghanim's Shard, it becomes exceedingly difficult for Enigma to land a good Black Hole against Outworld Destroyer and his team.
* Astral Imprisonment can also cancel Black Hole while Enigma does not have Black King Bar.
* Arcane Orb and Sanity's Eclipse can often make a short work out of Enigma and his Eidolons.

* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).

* Heroes that depend on disrupting fights with ability combos or big ultimate abilities 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.

* Bane can use Nightmare and Fiend's Grip to lock down Ursa early game and in team fights, forcing Ursa to buy a Black King Bar and making him very vulnerable to being kited once his Black King Bar is down to 6 seconds.
* Overall, Bane's potent disables force Ursa to build more defensive items and play more defensively in general.

* 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.

* Positioning-reliant heroes (Windranger, Tidehunter, Ursa...), since Earth Spirit can disrupt positioning with his Boulder Smash.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* The swarm beetle can waste Ursa's Overpower attacks.
* Ursa has no inherent way of disabling a slippery Weaver by preventing him from Shukuchiing or Time Lapseing away, as the slow from Earthshock is useless against Shukuchi's haste effect.
Additional:
* Earthshock's slow is ignored by Shukuchi.
* Ursa can be kited with Shukuchi and his burst damage will be negated with Time Lapse as long as Weaver survives it.
* The Swarm breaks Ursa's Blink Dagger, forcing him to deal with the beetles.

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

* If Ursa uses Enrage Brewmaster can use Cyclone to render him harmless during his ultimate.
* Brewmaster has two spells to slow down Ursa, allowing his team to kite around him easily.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Slark can detect early Roshan attempts due to Shadow Dance if he frequently checks the Pit.
* Enrage cannot restore attributes stolen by Essence Shift and will reduce his physical damage output.
* Even if Ursa initiates with Earthshock, Slark can Pounce away or use Dark Pact after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.

* 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, Luna, Puck, Slark, Nyx Assassin, etc.

* Lion has two low cast point disables (Hex and Earth Spike) to control Ursa before he buys a Black King Bar.
* Hex is one of the few abilities that cannot be dispelled even with an Aghanim's Scepter upgraded Enrage.
* Lion can control Ursa's low mana pool via Mana Drain.

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* Primal Roar and the slow from Boars makes kiting Ursa very easy.

* 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 cancelling a Black Hole.
* While Doom can be blocked by a Linken's Sphere, which is a common item on Enigma, Aghanim's Scepter upgraded Doom allows Doom to cast Doom on himself to affect enemies near him, and if Doom can combine this with Blink Dagger, he will be able to jump on Enigma while he is channeling Black Hole. Aghanim's Scepter upgraded Doom can also cancel Black Hole if any of Enigma's allies affected by Doom gets too close to him for it's duration, ignoring both, Black King Bar and Linken's Sphere.

* Doom makes Ursa less disruptive, and it cannot be dispelled with Enrage upgraded with Aghanim's Scepter.

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

* Heroes who rely heavily on melee attacks and lack early spell immunity are easily blocked and interrupted by Ink Swell: Lycan, Ursa, Troll Warlord.

* Laser can be cast on a initiating Ursa, normally causing him to waste multiple Overpower attacks, forcing him to either Black King's Bar, or Enrage to protect himself.
* Ursa will probably carry a Linken's Sphere to counter Tinker's Laser. Popping it with Scythe of Vyse is actually preferable, due to Laser's high Pure damage.
* While Ursa is a common Blink Dagger carrier, but he otherwise has no way to close the gap, Baiting him into using his Blink, then blinking away, allows Tinker to easily kite Ursa.
* Enrage is generally how Ursa disengages, Due to Tinker's high maneuverability, he can follow him until it runs out. then burst him down with high magic damage.

* Borrowed Time can give Abaddon a second chance after a Black Hole combo.
* Aphotic Shield can be used to save allies or Abaddon himself from Malefice.
* Abaddon can easily heal himself as well as his allies during a team fight, especially with Aghanim's Scepter upgraded Borrowed Time.

* 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. And since Enigma is not used to buy Diffusal Blade, this can be a very big problem for him.
* Without protection from Black King Bar, Wraith King can also cancel Black Hole with Wraithfire Blast that can also deal damage over time, putting Blink Dagger on cooldown.
* Vampiric Spirit can summon many skeleton warriors that can be used to deal with Enigma's Eidolons.

* 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 even through both, Black King Bar and Linken's Sphere.

* Blood Rite can potentially force him to activate Black King Bar 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.

* 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 with Burning Barrage and Tar Bomb.
* Clinkz often goes for a disabling item like Bloodthorn or Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar. Gleipnir can also root Enigma, preventing him from using Blink Dagger to escape from Clinkz.
* Even with Black King Bar, Clinkz can still easily kill Enigma as all of his abilities ingore spell immunity, and Enigma is a very easy target for Burning Barrage, which means Clinkz can solo Enigma at any stage of the game unless Clinkz is caught in Black Hole.

* 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.

* Ursa relies on the Blink-Earthshock combo to slow enemies to burst them, but Windranger can use Windrun to escape through Earthshock's duration.
* Windrun and Focus Fire can easily allow Windranger to kite Ursa and do good amounts of damage in the process.
Additional:
* Windranger can avoid Ursa's primary source of damage, Fury Swipes, by simply using Windrun. The slow from Earthshock is also rendered irrelevant by Windrun.
* Focus Fire and Windrun can be used to kite Ursa.

* Most of the of Jakiro's damage-over-time abilities put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.
Additional:
* Most of the of Jakiro's damage-over-time abilities put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
* Jakiro's Dual Breath, Liquid Fire, Macropyre and Liquid Frost from Aghanim's Shard can take out Enigma's Eidolons, reduce Enigma's attack speed and put Enigma's Blink Dagger on cooldown.
* Jakiro can easily cancel Black Hole with Ice Path as Enigma is a very easy target while channeling it.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.

* Plasma Field can spot an Ursa sneaking into Roshan's pit
* Static Link has a 800 link break distance, meaning Razor can stay close enough to drain Ursa' damage, but not too close to get attacked
* Static Link cannot be dispelled by Enrage
* With Storm Surge, Razor will usually be faster than Ursa in most cases
* Eye of the Storm melts through Ursa's armor

* Black Hole while definitely a threat to Drow Ranger, is very hard to land as she likes to keep her distance from allies and enemies alike. And if not caught in it, will kill Enigma very quickly due to his low health.
* Malefice can be removed with a Manta Style.
* Drow Ranger being a fairly low health, high armored agility carry doesn't take much damage from Midnight Pulse as others would.
* Demonic Conversion units die very quickly to Marksmanship or even just regular attacks not far into the game within 2 or 3 hits.

* 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 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.
* Anti-Mage's Blink will make him a very hard target to use Black Hole on, having to solo ult him later on in the game or leave him out of the Black Hole.

* Haunt can ruin Enigma's initiation with Blink Dagger, no matter where he is on the map.
* Spectre often buys Radiance, which allows her to deal damage over time to Enigma and put Blink Dagger on cooldown.
* Dispersion reflects the damage of Midnight Pulse and Black Hole inflicted back to Enigma. This can get even worse for Enigma if Spectre buys Blade Mail.
* All of Spectre's abilities ignore spell immunity, which means that even with Black King Bar, Enigma has absolutely little to no chance against Spectre at any stage of the game.

* Bristleback's constant harass from Quill Spray will greatly hurt Enigma's laning and kill his Eidolons.
* However, Bristleback has no way of canceling Black Hole at all. And Bristleback is not a hero that goes for disabling items to counter that problem.

* Walrus PUNCH! can interrupt Black Hole and it can pierce spell immunity and neither Black King Bar nor Linken's Sphere can protect Enigma from Walrus PUNCH! as Walrus PUNCH! is an auto-cast ability.
* In pretty much any phase of the game, Tusk's abilities can easily cancel Black Hole and disrupt Enigma's positioning.

* Enchant can dispel Overpower.
* Enchant's slow can help kite Ursa in fights and also in lane.
* Enchantress can out harass Ursa in lane by using her long attack range and Untouchable, as well as out sustaining him with Nature's Attendants.

* Ursa has no sustained AoE to deal with illusions, it becomes worse since Phantom Lancer can create more illusions in a matter of seconds.
* Diffusal Blade can be used to drain Ursa mana. This is a standard item for Phantom Lancer in every match.
* Doppelganger applies basic dispel on Phantom Lancer, which will remove the slow from Earthshock. It also resets fights with more illusions, making hard for Ursa to hit the real Phantom Lancer.
* Manta Style creates two more illusions and also applies a basic dispel, further complicating the problem for Ursa to deal with.

* Stone Form can easily interrupt heroes with long channeling spells, like Crystal Maiden, Bane, Witch Doctor, or Enigma.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.

* Heroes that rely on slows to get kills: Lifestealer, Night Stalker, Ursa, Phantom Assassin, Terrorblade.

* 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, and the Black Hole is not centered directly on Enigma.

* Heroes who can provide constant vision inside the Roshan Pit can negate one of the strongest advantages of Ursa, which is the possibility of quickly killing Roshan at the early game, with minimum itemization needed (Clockwerk, Beastmaster, etc).

* Melee carries such as Sven, Ursa or Lifestealer can be slowed and easily kited with Demonic Purge.

Additional:
* Shadow Demon's Demonic Purge renders Ursa useless even through Black King Bar as it slows him, continually purges his Overpower charges and can not be dispelled by Ursa's Enrage.
* Disruption is a good way to save teammates against Ursa. Disrupting Ursa is also a good way to kite him, as it can not be dispelled by Enrage.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Ursa struggles against heroes with strong (and especially undispellable) disables (Disruptor, Puck, Shadow Demon, Outworld Destroyer and etc).

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* Heroes with evasions: Phantom Assassin, Brewmaster, Hoodwink, Windranger.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* 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.

* 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. It also goes through Black King Bar and ignores Linken's Sphere.
* Fatal Bonds and Aghanim's Shard upgraded Shadow Word can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team. Also,their constant damage will put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
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 the channeling of Black Hole.
* Enemies often get clumped up around Black Hole to hit your allies, giving you a perfect opportunity to cast Fatal Bonds, Chaotic Offering, and Upheaval on multiple enemies.

* Viper Strike is a strong and breaks Fury Swipes, undispellable slow, making it much easier to kite Ursa for everyone.

* Without Black King Bar, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam or with 0.25s Eclipse Lucent Ministun talent for Eclipse and counter-initiate with Eclipse. This can get even worse for Enigma once Luna gets Aghanim's Scepter and combines it with 0.25s Eclipse Lucent Ministun talent that will allow Luna to use Eclipse from safe distance.
* If Luna chooses to use Eclipse in anticipation right after Enigma jumps in with Blink Dagger, she will be able to kill Enigma before he even gets a chance to use Black Hole. Aghanim's Scepter upgraded Eclipse can be used to counter-initiate against Enigma from safe distance if he has no Black King Bar available to use.
* Luna commonly buys Satanic, which can help her recover from Enigma's Black Hole in case she survives it.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons before Luna uses Eclipse. Aghanim's Shard upgraded Moon Glaives can be used to reduce damage Luna will take from Enigma's Eidolons and Black Hole if used in anticipation while also clearing waves of Enigma's Eidolons and damaging Enigma if he is too close to Luna.
* Bear in mind, however, that once Enigma gets Black King Bar, Luna will be out of solutions to cancel Black Hole, and going for Abyssal Blade on Luna can be risky due to Abyssal Blade's very short cast range.
Additional:
* Without Black King Bar, Luna will be able to cancel Enigma's Black Hole from safe distance with her Lucent Beam or with 0.25s Eclipse Lucent Ministun talent and counter-initiate with Eclipse. This can get even worse for Enigma once Luna gets Aghanim's Scepter and combines it with 0.25s Eclipse Lucent Ministun talent that will allow Luna to use Eclipse from safe distance.
* If Luna chooses to use Eclipse in anticipation right after Enigma jumps in with Blink Dagger, she will be able to kill Enigma before he even gets a chance to use Black Hole.
* Luna commonly buys Satanic, which can help her recover from Enigma's Black Hole in case she survives it.
* Moon Glaives combined with Lunar Blessing can make a short work of Enigma's Eidolons before Luna uses Eclipse.
* Bear in mind, however, that once Enigma gets Black King Bar, Luna will be out of solutions to cancel Black Hole, and going for Abyssal Blade on Luna can be risky due to Abyssal Blade's very short cast range.

* Illuminate can wipe the pushing Eidolons in a lane with ease, diminishing Enigma's laning presence by a lot.
* Solar Bind will severely slow down Enigma and make him more vulnerable to magical damage more he moves for it's duration.
* However, Keeper of the Light does not have any way to cancel Black Hole outside from Will-O-Wisp provided by Aghanim's Scepter.

* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint
* Corrosize Haze can force Ursa to cast Enrage defensively instead of offensively
* With Corrosize Haze, Slardar's team can quickly dispatch of Roshan, denying one of Ursa's greatest advantages

* 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 area-of-effect for Black Hole. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation.
* In the early game, Sniper can cancel Enigma's Black Hole with Assassinate's ministun. Due to the absolutely ginormous 3000 cast range on Assassinate, Sniper does not need to be too close to Enigma to cancel his Black Hole. Aghanim's Scepter upgraded Assassinate can also stun Enigma for a longer duration.
* Both Shrapnel and Assassinate put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
Additional:
* 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 Aghanim's Scepter.
* Enigma's Eidolons from Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with Mjollnir, a common item on Sniper.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.

* With Aghanim's Scepter upgraded Infest, Lifestealer can use it on enemy heroes to attack them and disarm them from inside, even if they are spell immune, which can give him the edge over the heroes he's weak against like Ursa, Phantom Assassin, Terrorblade or Troll Warlord.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.

* Heroes who rely strongly on melee physical damage will fare badly against Omniknight's Guardian Angel: Phantom Assassin, Juggernaut, Dragon Knight, Lycan, Ursa, Troll Warlord

* Heroes who have summons, which can be quickly cleared by his powerful area of effect skill: Nature's Prophet, Enigma, Lycan

* Heroes who can delivers a big chunk of damage in few hits will find themselves struggle against Templar Assassin's Refraction: Sven, Phantom Assassin, Ursa, Wraith King, Lifestealer

Additional:
* Templar Assassin usually places Psionic Traps inside the Roshan Pit (and can teleport herself to the traps with an Aghanim's Scepter), preventing Ursa from killing Roshan without getting noticed by the enemy team.

* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's Fiend's Grip, Faceless Void's Chronosphere, Magnus's Reverse Polarity, Axe's Berserker's Call, Pudge'sMeat Hook.

* 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's Aghanim's Scepter grants him Nimbus ability that 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.

* 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.
Additional:
* Ursa has no way to clear illusions quickly, making him vulnerable to Chaos bolt and Phantasm combo.
* Reality Rift can quickly relocate or reinitiate on Ursa once the duration of Enrage is over.
* Phantasm can be used to dispel Earthshock's slow. Manta Style is another item that counter Ursa greatly.
* Ursa has low mobility, once jumped on by Reality Rift, Ursa struggles to escape.

* Lycan's ultimate makes him immune to slows from Ursa's Earthshock as well as allowing him to outmaneuver Ursa during Enrage. Lycan can also easily chase down Ursa while shapeshifted, should Ursa try to flee.

* Inner Fire can damage and disarm Enigma's eidolons, which can then be cleared out with Burning Spears.
* Huskar's Burning Spears can deal serious damage over time to Enigma during laning and teamfights, and it can also disable Blink Dagger for a long time.
* Berserker's Blood that provides Huskar with magic resistance and bonus health regeneration makes it difficult for Enigma to take down Huskar. Huskar is also a common Satanic wielder, which can help him recover from Enigma's Black Hole in case he survives it. Enigma's only source of dealing Pure Damage that can bypass Berserker's Blood. This forces Enigma to buy Silver Edge, the only item that can help him against Huskar's Berserker's Blood.
* However, Huskar does not have any way to cancel Black Hole outside from Aghanim's Scepter upgraded Life Break that can force Enigma to attack Huskar if used on him.

* 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. Its stun duration is also amplified thanks to Spell Steal's debuff amplification.
* 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. It also does more damage and has a larger cast range thanks to Arcane Supremacy. A stolen Black Hole can also cancel Enigma's Black Hole.
Additional:
* Enigma's signature Black Hole can be devastating if being stolen and dropped on multiple heroes.
* Black Hole requires channeling. Since Enigma has no other ability to replace his last casted spell during channeling, Rubick can steal Black Hole relatively easily if he stays back.
* Rubick can interrupt Black Hole from Enigma, even with an activated Black King Bar, by casting the spell with Enigma in range with regards to the extra cast range granted by Arcane Supremacy.
* Black Hole can be interrupted by Telekinesis in the early game, giving enough time window to steal the spell.
* Bear in mind that an experienced Enigma will purchase Black King Bar and Linken's Sphere at the same time to prevent Rubick from stealing the spell, yet the extra Linken's Sphere will delay Enigma's power spike, so use it to Rubick's advantage.
* It is advised to build items around Black Hole as Rubick. Aghanim's Shard, Black King Bar , Aghanim's Scepter and even Refresher Orb are all legitimate item choices.
* Malefice is a decent source of damage and stun that helps with ganking. If stolen, it can be used to interrupt Black Hole as well.
* Demonic Conversion helpes with pushing and farming for Rubick.
* Fade Bolt effectively negates damage from Eidolons and helps with counter-pushing.
* Midnight Pulse is a solid skill for farming and teamfight damage, which is further amplified by Arcane Supremacy and talents.
* Unexpected enemy may take the effect of Midnight Pulse as that of Enigma's and soak up damage while unrealized.

* Enigma's abilities have a huge mana cost, meaning that Nether Ward will deal a lot of damage to Enigma.
* Pugna can heal allies trapped inside Black Hole thanks to Life Drain, Pugna can also damage multiple of Enigma's allies around him with Life Drain when he casts it on Aghanim's Shard upgraded Nether Ward during teamfight.
* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.
* Even though Pugna cannot cancel Black Hole on his own, smart Pugna can buy Orchid Malevolence to stop Enigma from channeling Black Hole and make him more vulnerable to counter-attacks with Decrepify and Life Drain.

* Nether Blast can easily kill Eidolons, especially when Enigma is pushing.

* Even with Black King Bar, Pudge's Meat Hook and Dismember can still disable Engima while he is channeling Black Hole as Enigma is a very easy target while channeling Black Hole.
* Pudge's Aghanim's Shard upgraded Dismember and Meat Hook are great ways to save allies from Black Hole.
* Enigma is prone to ganks in the jungle or in the off-lane without proper vision. Pudge can take advantage of Enigma's lack of mobility, and gank him often.

* Arcane Curse can be cast from a long range to put Enigma's Blink Dagger on cooldown.
* Global Silence can interrupt Enigma's Black Hole channeling through Black King Bar and Linken's Sphere, making Silencer one of Enigma's hard counters. But bear in mind that Global Silence can be dispelled with Black King Bar if activated first.
Additional:
* Silencer can easily ruin Enigma's initiation, as Global Silence cancels Black Hole, even through Black King Bar and Linken's Sphere.

* 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, Luna, 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.

* Tidehunter's Anchor Smash will cripple all of Enigma's Eidolons, and at a higher level, Tidehunter will be capable to instantly kill the whole group of them for a boost of gold.
* Kraken Shell negates Eidolons's damage and Enigma's auto attacks, making laning against Tidehunter nearly impossible for Enigma.
* Ravage has an insane radius, and considering that Enigma is prone to waiting around for a Blink Dagger and Black King Bar combo, Ravage's stun may catch Enigma off guard and put Blink Dagger on cooldown, limiting him a crucial teamfight time.

* Assuming they have not bought anti-evasion items, attack-dependent heroes such as Ursa, Terrorblade or Lifestealer can be a minor threat for Phantom Assassin early in the game, and may even be completely dominated by her thanks to her evasion.

* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.

* Winter's Curse, when directly targeted on Enigma, goes through Black King Bar, stopping Enigma's Black Hole channeling. It also turns his team against him, potentially killing him. Even if Enigma gets Linken's Sphere on top of Black King Bar, Splinter Blast can be used to pop Linken's Sphere, and Winter's Curse will stop Black Hole channeling.
* Splinter Blast can be targeted on an eidolon, killing off other eidolons and damaging nearby heroes as well.

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

* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* Medusa can also kill Eidolons with her Mystic Snake that can also greatly damage Enigma and drain some of his mana.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating and landing an effective Black Hole exceedingly difficult, because Stone Gaze can cancel Enigma's Black Hole even through spell immunity, which can discourage Enigma from even trying to initiate with Black Hole.
