[wiki] rating: 2.0 (winrate: 49% pickrate: 3%)Huskar
* Huskar is often at low health, providing large Thirst bonuses.
* 
Life Break triggers Rupture's damage.
Additional:
* Huskar is often at low health, providing large 
Thirst bonuses to Bloodseeker.
* Life Break can trigger 
Rupture's damage.
* A self applied 
Bloodrage together with Blademail means it's almost suicidal for Huskar to jump on Bloodseeker with Life Break
Slark
* Bloodseeker is one of the hardest counters to Slark.Thirst prevents Slark from healing in lane with 
Shadow Dance and may set him up for a kill while in the jungle,or retreating.
* Rupture will deal damage during 
Pounce.
* 
Dark Pact cannot dispel Rupture, preventing Slark from escaping ganks.
Additional:
* Thirst stops Shadow Dance's passive health regeneration if Slark's current health is below the Thirst's visibility threshold.

Chaos Knight
[wiki] rating: 2.0 (winrate: 47% pickrate: 3%)Huskar
* Huskar's low armor and movement speed make an easy target for Chaos Knight to initiate on with 
Reality Rift and 
Chaos Bolt.
* Beside 
Inner Fire, Huskar has no reliable area of effect ability to clear Phantasm illusions.
* Huskar likes to fight at low health to benefit from his 
Berserker's Blood, thus vulnerable to Chaos Knight's high burst physical damage.
Additional:
* Chaos Bolt can stun Huskar when he jump in with Life break, giving 4 seconds maximum for Chaos Knight to deliver a beatdown.
* Reality Rift further reduces Huskar's low armor, boosting Chaos Knight's damage even more.
* Berserker's Blood offer no protection against 
Chaos Strike, which deal physical damage.
* 
Phantasm can be used to dispel the disarm from Inner Fire.
* Although Huskar can use this to disarm the illusion instead, buying himself some times.
Slark
* 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.
Naga Siren
[wiki] rating: 1.6 (winrate: 51% pickrate: 3%)Huskar
* 
Mirror Image can cause Huskar to Life Break the wrong target.
* 
Rip Tide reduces Huskar's already low armor.
* 
Song of the Siren allows teams to recover from Huskar's initiation, as well as the damage over time from Burning Spears.
Slark
* 
Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: 
Phantom Assassin, 
Magnus, 
Slark, 
Riki, 
Faceless Void, 
Storm Spirit.
Outworld Destroyer
[wiki] rating: 1.6 (winrate: 51% pickrate: 10%)Huskar
* Heroes with pure damage can kill Huskar when he inevitably gets low on health: 
Outworld Destroyer, 
Silencer.
Additional:
* Outworld Destroyer can dodge Life Break with Astral Imprisonment, leaving him unharmed while Huskar loses HP.
* Sanity's Eclipse can deal massive damage to Huskar before he builds up his Berserker's Blood stacks due to Huskar's low mana pool.
Slark
* Outworld Destroyer can disrupt Slark's attacks with 
Astral Imprisonment either by banishing Slark or his target.
* Slark's low heathpool means he will die quickly to 
Arcane Orb if he is directly attacked by Outworld Destroyer
* Slark has low intelligence gain, making him easy to finish with 
Sanity's Eclipse if he tries to run with Shadow Dance
Additional:
* Arcane Orb deals pure damage, which ignores the armor granted from permanent agility stacks.
* Astral Imprisonment can disrupt any Pounce attempt by banishing the leashed ally.
* Slark's low mana pool makes him more susceptible to Sanity's Eclipse.
Slardar
[wiki] rating: 1.6 (winrate: 50% pickrate: 4%)Huskar
* 
Corrosive Haze and 
Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
Slark
* 
Slardar's level 25 talent makes Corrosive Haze undispellable, thus providing his allies vision of Slark.
Phantom Lancer
[wiki] rating: 1.6 (winrate: 50% pickrate: 2%)Huskar
* Heroes with illusions can overwhelm Huskar: 
Phantom Lancer, 
Anti-Mage, 
Arc Warden, 
Chaos Knight.
Slark
* 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.
* 
Phantom Rush helps Phantom Lancer chase down Slark if he tries to escape with Pounce.
Additional:
* Slark has no sustained AoE damage to deal with a lot of Phantom Lancer's illusions.
*

* 
Spirit Lance can give vision of Slark via spawning an illusion, making it harder for him to juke and gain the passive bonus from Shadow Dance.
* Phantom Rush helps Phantom Lancer chase down Slark when he jumps away with Pounce.
Ancient Apparition
[wiki] rating: 1.6 (winrate: 50% pickrate: 5%)Huskar
* Ice Blast prevents Huskar from healing with Berserker's Blood and negates any lifesteal, making him significantly weaker in battle.
* 
Burning Spear and Life Break cost Huskar his own health, killing him under the effects from Ice Blast.
* Huskar often builds 
Armlet of Mordiggian which can be deadly during Ice Blast.
Additional:
* 
Ice Blast prevents Huskar from healing, regeneration, health gained from activating an Armlet of Mordiggian and will kill him when his health dips below a threshold. This makes it very dangerous for him to use his abilities.
Slark
* Heroes like Slark, 
Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
Additional:
* Ice Blast stops Shadow Dance's passive health regeneration, even when Slark is not in vision.
Viper
[wiki] rating: 1.6 (winrate: 49% pickrate: 4%)Huskar
* His 
Poison Attack is very useful against Huskar, since he tends to stay at low health.
* 
Nethertoxin disables passive skills like Berserker's Blood.
* It is dangerous for Huskar to jump on Viper because 
Corrosive Skin and 
Viper Strike with the slowdown of movement and attack speed which usually will be deadly for Huskar.
Additional:
* Nethertoxin disables Berserker's Blood, which Huskar relies upon for attack speed and healing.
* The damage from Burning Spear and Life Break is largely absorbed by Corrosive Skin. It also will return some damage, making it risky to use Burning Spears in the laning stage.
* Because Huskar wants to be on low health for Berserker's Blood, he is particularly vulnerable to Poison Attack.
Slark
* Heroes with Break abilities will prevent Slark from regenerating and gaining Essence Shift stacks: 
Viper, 
Shadow Demon, etc.
Additional:
* Nethertoxin negates Essence Shift and the regeneration aspect of Shadow Dance.
* Dark Pact doesn't mean a lot against Viper's ubiquitous slows.
* Viper becomes a relevant presence in team fights before Slark can procure his standard items (e.g. 
Shadow Blade).
Queen of Pain
[wiki] rating: 1.4 (winrate: 46% pickrate: 6%)Huskar
* He's the kind of hero that likes to remain at low hp, which is perfect for Queen of Pain to burst with Sonic Wave.
* You should be able to blink away after he jumps on you with Life Break.
Slark
* Both Scream of Pain and Sonic Wave should hit him during his Shadow Dance.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, Faceless Void, Magnus, 
Mirana, 
Monkey King, 
Morphling, 
Pangolier, Phantom Assassin, 
Phoenix, 
Puck,

Sand King, 
Spirit Breaker, 
Timbersaw, 
Tusk.
Dazzle
[wiki] rating: 1.2 (winrate: 52% pickrate: 9%)Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: 
Weaver, 
Dazzle, 
Bristleback, 
Vengeful Spirit.
Slark
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, 
Abaddon.
Abaddon
[wiki] rating: 1.2 (winrate: 50% pickrate: 6%)Huskar
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as 
Huskar, 
Venomancer, or Phoenix.
Additional:
* Huskar's damage over time gives Abaddon the opportunity to shield and heal his allies.
* 
Borrowed Time also makes Abaddon a hard support to gank, thus negating Huskar's early game dominance.
Slark
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon.
Doom
[wiki] rating: 1.2 (winrate: 47% pickrate: 8%)Huskar
* An 
Aghanim's Scepter upgraded 
Doom can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, 
Enchantress, Huskar, 
Underlord.
Slark
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, 
Death Prophet, Puck, 
Doom.
Omniknight
[wiki] rating: 1.0 (winrate: 55% pickrate: 3%)Slark
* Slark's dependence on Pounce and close range makes him very easy to hit with 
Purification.
* Slark's damage, even with a high count of Essence Shift stacks, is easily negated by Omniknight's heals and 
Guardian Angel.
Brewmaster
[wiki] rating: 1.0 (winrate: 52% pickrate: 1%)Huskar
* Brewmaster can use Cyclone to disable Huskar's healer for much longer than most other heroes can, to make Huskar vulnerable.
* Huskar has no way to stop Brewmaster from using Primal Split by himself, but can cut a good amount of his high health away if Huskar's team wants to burst Brewmaster down during a different disable.
Clinkz
[wiki] rating: 1.0 (winrate: 52% pickrate: 7%)Huskar
* Huskar's Berserker's Blood provides no protection against Clinkz's physical damage output.
* Huskar has no way to disrupt Clinkz's attacks and no way to kill Clinkz alone, as Clinkz can easily go invisible, teleport away, or even fight back.
* Clinkz will often build the items that counter Huskar and the items he usually builds. These include 
Black King Bar or 
Monkey King Bar for 
Heaven's Halberd, or a disable item like 
Scythe of Vyse or 
Bloodthorn to prevent him from using Inner Fire to disarm.
Night Stalker
[wiki] rating: 1.0 (winrate: 52% pickrate: 4%)Slark
* With Dark Ascension he can keep vision on Slark, disabling his Shadow Dance regeneration.
* Night Stalker is very fast so without the Pounce in lane, he can simply out distance him during the night.
* Slark is matched in night vision by only a few heroes, Night Stalker happens to be one of them.
Elder Titan
[wiki] rating: 1.0 (winrate: 50% pickrate: 1%)Slark
* Natural Order aura prevents Slark from gaining armor from the agility stolen with Essence Shift.
* Echo Stomp and Earth Splitter can hit Slark through his Shadow Dance ultimate.
* Slark's stats gain is relatively low compared to most agility carries making him quite squishy without his agility-based armor.
Necrophos
[wiki] rating: 1.0 (winrate: 50% pickrate: 7%)Huskar
* Because Huskar tends to stay at low health to gain the maximum bonuses from Berserker's Blood, it makes him an exceptionally prime target for 
Reaper's Scythe.
Additional:
* Huskar is often at low health, making him easy prey for Reaper's Scythe.
* Ghost Shroud prevents Huskar from stacking Burning Spear, and if Heartstopper Aura stacks are active, can regenerate health lost to existing stacks.
Primal Beast
[wiki] rating: 1.0 (winrate: 49% pickrate: 9%)Slark
* Dark Pact, Shadow Dance and 
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool; shedding it with Essence Shift can take time and may allow Primal Beast to build Uproar against him. Should he survive Slark's slew of skills, Primal Beast can simply Pulverize him to finish him off.
Windranger
[wiki] rating: 1.0 (winrate: 49% pickrate: 10%)Huskar
* 
Windrun makes it impossible to hit Windranger with Burning Spears.
* Huskar cannot toggle Armlet of Mordiggian to regain health while taking constant damage from 
Focus Fire.
Additional:
* Windranger prevents Huskar from landing Burning Spears by using Windrun.
* Because Huskar tends to be at low health, Focus Fire and Powershot are good abilities against him.
Disruptor
[wiki] rating: 1.0 (winrate: 48% pickrate: 10%)Slark
* Thunder Strike provides vision on him while Slark is invisible.
* Glimpse's range at lvl 3-4 is more than enough to pull him back to a favorable position for your team to group up and kill him.
* Even though he is capable of picking you off and deal enough damage to kill you, Slark will be literally sticking his neck out, since jumping on Disruptor means being on his battleground.
* AoE silence and the ability to mute Black King Bar is deadly to Slark at all stages of the game.
Additional:
* 
Static Storm and 
Kinetic Field locks down Slark, as he cannot use Dark Pact to dispel any disables, or Pounce out while silenced.
* 
Glimpse puts an end to any attempts at ganking Disruptor or his allies, and also negates Slark's mobility by bringing him back into the fight if he tries to escape with Pounce.
Invoker
[wiki] rating: 1.0 (winrate: 48% pickrate: 14%)Huskar
* Quas Exort Invoker has high physical damage in the form of Cold Snap and Forged Spirits that allows him to trade hits with Huskar.
* Although Huskar can dispel Cold Snap with Life Break.
* Sun Strike deals pure damage and pierces spell immunity, and Huskar tends to drain his HP, making him a susceptible target.
Tiny
[wiki] rating: 1.0 (winrate: 48% pickrate: 13%)Slark
* 
Toss and 
Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's Essence Shift permanent agility steal does not do much against him.
Shadow Fiend
[wiki] rating: 1.0 (winrate: 48% pickrate: 18%)Slark
* Shadow Dance does not protect Slark from Shadow Fiend's AoE spells.
Faceless Void
[wiki] rating: 1.0 (winrate: 48% pickrate: 9%)Huskar
* Carries that can out damage Huskar will do well against him: 
Legion Commander, Faceless Void, 
Troll Warlord, Phantom Assassin.
Slark
* Time Dilation while Dark Pact and Pounce are on cooldown will make these abilities unusable for a long time, reducing his escape potential. However, Time Dilation is dispellable with Dark Pact so it needs to be timed well.
* Chronosphere will not reveal Slark during Shadow Dance but covers the whole duration of Shadow Dance making him unable to use it to attack or escape. Slark still receives the regeneration benefit from Shadow Dance.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Pugna
[wiki] rating: 1.0 (winrate: 47% pickrate: 3%)Slark
* 
Nether Blast will still hit Slark in Shadow Dance.
* Pugna can rarely target Slark directly with 
Decrepify, but he can use it defensively on an ally to prevent Slark from getting stacks.
* Despite being somewhat easy to break with Pounce, Pugna can damage Slark and provide vision over him with 
Life Drain.
Shadow Demon
[wiki] rating: 1.0 (winrate: 47% pickrate: 1%)Huskar
* Shadow Demon's 
Shadow Poison can quickly stack to the point where Huskars generally low health is easily finished off.
* Shadow Demon's 
Disruption can turn Huskar's high attack speed and regeneration against him, It also makes him an easy target for Shadow Poison,
* Shadow Demon commonly builds a 
Meteor Hammer, allowing him to land a heavy stun on Huskar
* Shadow Demon's upgraded 
Demonic Purge breaks Huskar, It also pierces Spell Immunity, Without his passive for 7 seconds Huskar quickly falls in battle
* However note that Shadow Demon is a squishy target and you can often overwhelm him if he is alone, But he can still Disrupt you to escape
Additional:
* Shadow Poison can quickly stack up on Huskar, And with his naturally low health you don't need as many stacks to be effective.
* Disruption turns Huskars high attack speed against him, They also have the highest survivability as illusions due to his passive Berserker's Blood, It also allows you to put Shadow Poison stacks on him,
* Dissimulate turns Huskar's burning damage against his team, You can cast it on an ally who is taking a bunch of Burning Spear stacks and cause Huskar to take high amounts of damage as well
* Scepter upgraded Demonic Purge is your most effective weapon against him, It's 7 second Break causes him to quickly die in battle
Slark
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, 
Sven, Slark, Phantom Lancer.
* Once you have an Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, 
Spectre, Phantom Assassin, Enchantress, 
Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Slark
* Heroes who can dispel will be able to remove remove Soul Catcher's debuff to instantly bring the health of affected heroes back to a considerable amount: Abaddon, Slark, Legion Commander, 
Oracle.
Grimstroke
[wiki] rating: 1.0 (winrate: 46% pickrate: 4%)Slark
* 
Phantom's Embrace can't be dispelled by Slark's Dark Pact.
Muerta
[wiki] rating: 1.0 (winrate: 45% pickrate: 13%)Slark
* Slark's low health and reliance on high built armor from Essence Shift makes him susceptible to Muerta's 
Pierce the Veil.
* Muerta cannot be attacked by Slark's physical attacks and Essence Shift during Pierce the Veil.
* Muerta's 
Dead Shot can hit Slark during his Shadow Dance.
Meepo
[wiki] rating: 0.6 (winrate: 56% pickrate: 1%)Slark
* 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.
Death Prophet
[wiki] rating: 0.6 (winrate: 55% pickrate: 11%)Slark
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, Puck, Doom.
Legion Commander
[wiki] rating: 0.6 (winrate: 51% pickrate: 13%)Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Additional:
* Life Break is almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural 
Blade Mail carrier.
* Huskar's low survivability and mostly on low health makes him particularly vulnerable to Legion Commander's high physical damage.
Underlord
[wiki] rating: 0.6 (winrate: 51% pickrate: 3%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, Underlord, 
Leshrac, 
Dark Seer, 
Earthshaker, Timbersaw, 
Crystal Maiden.
Jakiro
[wiki] rating: 0.6 (winrate: 51% pickrate: 12%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden.
Troll Warlord
[wiki] rating: 0.6 (winrate: 50% pickrate: 2%)Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, resulting in Huskar's attacks missing a lot of the time if it isn't dispelled.
* Troll Warlord's Fervor ramps up in a very similar way as Huskar's Berserker's Blood: as soon as Huskar has high enough health regeneration, Troll Warlord has a high enough attack speed to negate it.
Storm Spirit
[wiki] rating: 0.6 (winrate: 49% pickrate: 6%)Huskar
* 
Ball Lightning, if timed correctly, and in the right place, can drag Huskar using Life Break all the way to fountain. Or you could also lure him on top of a pillar or into a techies minefield.
Slark
* Heroes that rely on their high mobility such as Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as 
Dust of Appearance or 
Gem of True Sight) for invisible heroes that could potentially escape your clutches.
Slark
* Pounce's leash prevents Storm Spirit from using Ball Lightning, making it hard for Storm Spirit to escape a gank from Slark.
* Dark Pact can dispel 
Orchid Malevolence's Soul Burn.
Terrorblade
[wiki] rating: 0.6 (winrate: 45% pickrate: 2%)Huskar
* Sunder can prevent Terrorblade's or an ally's death by swapping health, making damage-over-time abilities inefficient. Heroes that rely on damage-over-time abilities like Venomancer and Huskar will have a hard time against Sunder.
Juggernaut
[wiki] rating: 0.4 (winrate: 50% pickrate: 11%)Huskar
* 
Blade Fury makes Juggernaut immune to the damage from Life Break and Burning Spears.
* It can be instantly activated the second Juggernaut sees Huskar flying towards him with Life Break, blocking all damage.
* 
Healing Ward effectively negates any damage-over-time from Burning Spears.
* Huskar has no defense against 
Omnislash and takes heavy damage due to his low armor.
Slark
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, 
Ember Spirit, Slark etc.
Additional:
* Blade Fury does not offer any protections against Essence Shift, as it can go through spell immunity and reduces attribute.
* Slark can pounce away from Juggernaut and he cannot prevent or chase slark.
* Shadow Dance prevent Juggernaut from using Omnislash altogether, while regen himself at a higher rate. Slark can freely hit juggernaut without any fears of retaliation.
Sand King
[wiki] rating: 0.4 (winrate: 50% pickrate: 6%)Slark
* He has a hard time killing Sand King because of the survivability he gets from Burrowstrike and Sand Storm.
* Shadow Dance, which usually allows Slark to survive fights, is ineffective against Sand King's AoE damage.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Crystal Maiden
[wiki] rating: 0.4 (winrate: 49% pickrate: 13%)Slark
* Though Slark's large damage output is most certainly a concern for the squishy Crystal Maiden, she does perform fairly well against him when coupled with aid from her team.
* Slark has no innate way to cancel Freezing Field, but the common purchase of 
Skull Basher does make Slark a substantially greater threat to Crystal Maiden as the game progresses.
* Freezing Field can still hit Slark while he is under the effect of Shadow Dance, and for the early and mid game, the damage output of Crystal Maiden's ultimate outscales Slark's passive regeneration, making a quick use of Freezing Field as soon as Slark uses Shadow Dance a great way to combat him.
* Crystal Maiden's Frostbite and Crystal Nova are helpful in disabling and slowing the slippery Slark so he can be killed by her teammates.
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: 
Lich, Crystal Maiden, Silencer, 
Keeper of the Light, Venomancer, etc.
Shadow Shaman
[wiki] rating: 0.4 (winrate: 49% pickrate: 6%)Huskar
* Mass Serpent Ward rips apart Huskar quickly due to his poor armor.
* As soon as Huskar jumps in, he will be vulnerable to Shadow Shaman's disables if he does not have Black King Bar.
Slark
* 
Nyx Assassin, 
Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Enchantress
[wiki] rating: 0.4 (winrate: 46% pickrate: 2%)Huskar
* 
Untouchable makes it near impossible to stack Burning Spears.
* 
Impetus' pure damage puts an instant end to Huskar's low-health brinkmanship.
Slark
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Lina
[wiki] rating: 0.2 (winrate: 50% pickrate: 16%)Huskar
* Heroes with high magical burst can easily kill Huskar when he is at low health: 
Lion, Lina, 
Skywrath Mage
Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, 
Zeus
Slark
* Dark Pact can be cast during the cast animation of Light Strike Array and dispel its stun.
* Pounce allows Slark to close the gap to Lina.
* Shadow Dance prevents Lina from killing Slark with her Laguna Blade when his HP gets low.
Lion
[wiki] rating: 0.2 (winrate: 45% pickrate: 10%)Huskar
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Slark
* Pounce allows Slark to close in on Lion and prevent him from escaping.
* Lion's fragile health pool makes him easy prey for Slark's high burst damage through Pounce, Dark Pact and right-clicks.
* Shadow Dance prevents Lion from casting Hex, Mana Drain, or Finger of Death on Slark.
* Dark Pact allows Slark to dispel any of Lion's disables.
Templar Assassin
[wiki] rating: -2.0 (winrate: 48% pickrate: 4%)Huskar
* Huskar's burn damage from Burning Spear is incredibly strong against Templar Assassin as it completely cancels out her Refraction from the burning over time which results in making her very vulnerable to ganks and harassments, and in turn forcing her out of the lane.
Slark
* Dark Pact rips through 
Refraction charges and still steals attributes during Refraction.
* Pounce and Dark Pact will still hit Templar Assassin while she is 
Melded. Since she cannot move, both abilities will be easy for Slark to land.
Drow Ranger
[wiki] rating: -2.0 (winrate: 51% pickrate: 18%)Huskar
* Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* Berserker's Blood and Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.
Slark
* 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.
Razor
[wiki] rating: -2.0 (winrate: 52% pickrate: 7%)Huskar
* Life Break along with Burning Spear can quickly kill Razor before Static Link steals enough damage for Razor to take down Huskar.
* Berserker's Blood can make stealing Huskar's damage and using it against him somewhat dangerous, as Huskar will be able to inflict more and more Burning Spears rapidly.
Slark
* Pounce can easily break Static Link, making it less powerful against him.
* Slark is one of the few heroes who can man fight a Razor, because of Essence Shift.
* Shadow Dance can prevent Razor from killing him and may provide an opportunity to kill Razor due to it preventing Razor from attacking Slark.
Nature's Prophet
[wiki] rating: -1.6 (winrate: 46% pickrate: 12%)Huskar
* 
Sprout will not protect Nature's Prophet from Huskar if he has already locked on with Life Break.
* Even a farmed Nature's Prophet is usually not durable enough to fight Huskar alone.
Slark
* Pounce also stops 
Nature's Prophet's 
Teleportation.
Pangolier
[wiki] rating: -1.6 (winrate: 48% pickrate: 9%)Huskar
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Slark
* Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now applying leash to the target, Pangolier is helpless against Slark since both his Swashbuckle and Rolling Thunder will be disabled. Pounce also help Slark to easily escape from Rolling Thunder.
Clockwerk
[wiki] rating: -1.6 (winrate: 49% pickrate: 8%)Huskar
* Clockwerk cannot go head-to-head with Huskar in Power Cogs, as Berserker's Blood and Life Break will destroy him faster than the other way around.
Additional:
* Clockwerk's abilities cannot handle Huskar in a one-on-one fight, even if he gets the jump on him.
Slark
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, 
Terrorblade, 
Ursa, Weaver, 
Broodmother, Slark, Abaddon, 
Wraith King, 
Lifestealer.
Phoenix
[wiki] rating: -1.6 (winrate: 50% pickrate: 5%)Huskar
* Huskar's high attack speed can counteract 
Fire Spirits, and easily destroy the 
Supernova.
Additional:
* Berserker's Blood will let Huskar easily face down a Supernova with increased attack speed.
* 
Icarus Dive may not be an easy escape from Huskar either as he can chase Phoenix during it with Life Break if Huskar times it right.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Venomancer
[wiki] rating: -1.6 (winrate: 50% pickrate: 4%)Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Additional:
* Huskar can easily regenerate lost health from DoT spells through Berserker's Blood rendering them ineffective
* Venomancer has little armor and mobility, and rarely builds Linken's Sphere, so he is quite vulnerable to Life Break.
Slark
* Dark Pact can dispel Venomous Gale and Poison Sting.
* Shadow Dance allows Slark heightened regeneration when out of vision making DoTs effects less threatening.
Magnus
[wiki] rating: -1.6 (winrate: 51% pickrate: 15%)Huskar
* Magnus cannot manfight Huskar even with Empower, Berserker's Blood's high attack speed and health regeneration, combined with Huskar's high health and Burning Spear stacks will allow Huskar to kill Magnus before he can kill him.
* From a safe distance, Huskar can surprise and counter Magnus's initiation with Life Break and Burning Spear.
* Burning Spear also deals damage over time, disabling Blink Dagger and preventing him from initiating or escaping.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Monkey King
[wiki] rating: -1.2 (winrate: 47% pickrate: 8%)Huskar
* Burning Spears can put Monkey King's 
Tree Dance on cooldown.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Bounty Hunter
[wiki] rating: -1.2 (winrate: 51% pickrate: 7%)Huskar

Aphotic Shield and Borrowed Time

Rage and 
Infest

Fortune's End and 
False Promise

* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Sniper
[wiki] rating: -1.0 (winrate: 44% pickrate: 11%)Slark
* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.
Medusa
[wiki] rating: -1.0 (winrate: 45% pickrate: 1%)Slark
* Medusa is especially vulnerable to Essence Shift, as both strength and intelligence contribute to her effective HP, while agility contributes to her damage.
* Dark Pact when timed right can be used to dispel Stone Gaze right after it petrifies Slark, allowing him to keep attacking Medusa throughout the duration.
Additional:
* Medusa cannot chase Slark in any way and has no disable beyond her ultimate, making her unable to stop him getting away and regenerating before coming back to finish her off.
* Essence Shift particularly removes 1 intelligence point per hit, thus lowering Medusa's mana pool's cap and leaving her much more vulnerable in prolonged fights.
Kunkka
[wiki] rating: -1.0 (winrate: 47% pickrate: 3%)Huskar
* Since Tidebringer has a 4 second cooldown, Kunkka has little availability to manfight Huskar.
Batrider
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Slark
* Dark Pact can dispel Flaming Lasso if is used in anticipation, but a Blink initiation from fog can catch the Slark off guard.
* Slark can also take off any Sticky Napalm stacks with Dark Pact in lane.
Additional:
* Shadow Dance's passive can inform Slark when he's under enemy vision, meaning it'll be very hard to catch Slark off-guard with 
Flaming Lasso.
* Flaming Lasso is dispelled by Dark Pact. Its casting can be prevented with Shadow Dance or Depth Shroud (it requires 
Aghanim's Shard).
Ogre Magi
[wiki] rating: -1.0 (winrate: 48% pickrate: 7%)Slark
* Dark Pact dispels Ignite's slow and Fireblast's stun.
* Shadow Dance allows Slark to regenerate HP, even when he is affected by Ignite and Fireblast.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 48% pickrate: 3%)Slark
* Arctic Burn and Splinter Blast debuffs are dispellable with Dark Pact. Arctic Burn is also no escape against Pounce.
* Cold Embrace gives Slark free Essence Shift stacks.
* However, Essence Shift works against allies, and Slark's low health pool means that if he's the target for Winter's Curse, he will go down very quickly.
Ember Spirit
[wiki] rating: -1.0 (winrate: 48% pickrate: 11%)Huskar
* Ember Spirit does minimal damage to Huskar until the very late game.
Wraith King
[wiki] rating: -1.0 (winrate: 48% pickrate: 4%)Slark
* Dark Pact, if timed correctly, can dispel Wraithfire Blast's stun and slow.
* Since Wraith King has a lot of health and multiple lives, Slark can keep gaining Essence Shift stacks, increasing armor, damage, and attack speed and can beat down Wraith King twice.
* Slark sometimes carries 
Diffusal Blade to burn mana as an attempt to shut down Reincarnation.
* Because Wraith King has no AoE abilities, Shadow Dance is particularly useful against Wraith King.
Tidehunter
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Slark
* Dark Pact dispels debuffs from Gush, Anchor Smash and even Ravage if timed correctly.
* Kraken Shell cannot restore attributes stolen by Essence Shift or dispel the leash if he gets Pounced.
Pudge
[wiki] rating: -1.0 (winrate: 49% pickrate: 29%)Slark
* Dark Pact dispels Dismember if timed correctly.
* Pounce allows Slark to escape Pudge's Rot once Dismember is over, and allows him to dodge hooks.
* Shadow Dance hides Slark and grants him a high degree of mobility, which can make him a difficult target to hook and also protects him from Pudge's Dismember (including allies with an Aghanim's Shard).
Zeus
[wiki] rating: -1.0 (winrate: 49% pickrate: 14%)Slark
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Huskar
* Huskar's Burning Spears chip through his low health pool quickly.Consequently, he is forced to either invest on health regen or abandon the lane.
* Reliant on magic damage, there is little he can do against Huskar.
* Huskar will usually kill him if he gets Life Break off,given Zeus' poor mobility.
Slark
* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: 
Lycan, Slark, Storm Spirit, Spectre and others.
Earth Spirit
[wiki] rating: -1.0 (winrate: 49% pickrate: 3%)Slark
* Pounce's root prevents Earth Spirit from using Rolling Boulder to escape, making it easier for Slark to shut him down especially in the laning phase.
Gyrocopter
[wiki] rating: -1.0 (winrate: 50% pickrate: 7%)Huskar
* Life Break and Burning Spear usually kills Gyrocopter before he can do much damage to Huskar.
* Inner Fire applies a disarm on all enemies, which can be a hindrance to Gyrocopter.
Earthshaker
[wiki] rating: -1.0 (winrate: 51% pickrate: 10%)Slark
* Earthshaker's many stuns can lock down slippery heroes like Slark in his Shadow Dance and Weaver in his 
Shukuchi.
Additional:
* Earthshaker's many AoE stuns help lock down Slark and will often waste the duration of Shadow Dance.
* As a frequent 
Force Staff buyer,he can later on escape or save teammates from Pounce.
Huskar
* Earthshaker's stuns will rarely save him once Huskar has initiated on him with Life Break.
* A full initiation combo will not kill Huskar, only lower his health and increase his attack speed.
Slark
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: 
Clinkz, Slark, Storm Spirit
Spectre
[wiki] rating: -1.0 (winrate: 51% pickrate: 11%)Slark
* Essence Shift deals 20 extra damage by draining one strength per hit, which cannot be reduced or spread by 
Dispersion.
* Pounce prevents Spectre from escaping with 
Spectral Dagger.
* 
Haunt illusions usually don't deal a lot of damage to Slark as he tends to buy a Shadow Blade, preventing 
Desolate's and Diffusal Blade's damage and activating Shadow Dance's regeneration to make up for any damage caused by 
Radiance.
* Slark is a natural carrier of 
Silver Edge, which helps break both Desolate and Dispersion.
Mirana
[wiki] rating: -1.0 (winrate: 53% pickrate: 15%)Slark
* If Slark sees the Sacred Arrow before it hits him, he can use Dark Pact to remove it a moment later.
* Pounce prevents Mirana from escaping with Leap.
* Slark can survive Mirana's Aghanim's Scepter​ combo with Shadow Dance.
Morphling
[wiki] rating: -0.6 (winrate: 44% pickrate: 8%)Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Dragon Knight
[wiki] rating: -0.6 (winrate: 45% pickrate: 5%)Huskar
* Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, Life Break remains a constant threat due to the slow and percentage-based damage.
Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.
Keeper of the Light
[wiki] rating: -0.6 (winrate: 49% pickrate: 3%)Slark
* Melee carries during the laning phase: Sven, Slark
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Slark
* Heroes with dispels: Legion Commander, Oracle, Slark, Phantom Lancer
Tusk
[wiki] rating: -0.6 (winrate: 49% pickrate: 15%)Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Enigma
[wiki] rating: -0.6 (winrate: 50% pickrate: 3%)Slark
* 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.
Lich
[wiki] rating: -0.6 (winrate: 51% pickrate: 9%)Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Additional:
* Lich is going to have a hard time nuking Huskar because of his high health regeneration from Berserker's Blood.
* Lich is a squishy support without an escape mechanism, making Lich an easy kill thanks to Life Break and Burning Spear.
* Once Huskar has Armlet of Mordiggian, even a maxed out Frost Blast will struggle to finish Huskar off.
Beastmaster
[wiki] rating: -0.6 (winrate: 51% pickrate: 2%)Slark
* Heroes with strong dispels can remove Primal Roar's stun: Abaddon, Slark, Oracle.
Io
[wiki] rating: -0.6 (winrate: 51% pickrate: 4%)Slark
* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, 
Sniper, Slark, Phantom Assassin, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Undying
[wiki] rating: -0.6 (winrate: 52% pickrate: 10%)Huskar
* Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
Riki
[wiki] rating: -0.6 (winrate: 54% pickrate: 13%)Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Visage
[wiki] rating: -0.6 (winrate: 55% pickrate: 2%)Huskar
* Heroes with damage over time abilities can quickly eat through Gravekeeper's Cloak charges like Huskar, Jakiro and Queen of Pain.
Rubick
[wiki] rating: -0.4 (winrate: 47% pickrate: 25%)Slark
* Rubick usually positions in the back of a team. Heroes who can sneak up and assault Rubick (e.g. Slark) or damage Rubick from great distance (e.g. Spectre, Sniper) should be treated cautiously, as otherwise the matchup usually ends up badly for Rubick.
Slark
* Pounce and Dark Pact together with some attacks can take Rubick down quickly.
* Rubick's spells are ineffective due to the strong dispel effect of Dark Pact.
* Even though Shadow Dance is a great spell to steal, Slark's untargetable nature and his low cooldown spells prevents Rubick from stealing. Also Slark can freely use other abilities for the duration of Shadow Dance.
Bane
[wiki] rating: -0.4 (winrate: 48% pickrate: 2%)Slark
* 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.
Slark
* Dark Pact can dispel Enfeeble, as well as Nightmare and Fiend's Grip when timed correctly.
* Shadow Dance can protect Slark from Bane's single-target abilities.
Luna
[wiki] rating: -0.4 (winrate: 49% pickrate: 2%)Slark
* With Dust of Appearance, Luna will be able to use 
Eclipse on invisible heroes. Be mindful that Slark is exception because he'll be able to remove the debuff with Dark Pact.
Slark
* Shadow Dance prevents Luna from damaging Slark, and together with Silver Edge he can easily chase her or escape from her.
* Luna has no way to escape from Pounce's leash.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Additional:
* Luna's lack of mobility and escape abilities makes her easily to gank for Slark.
* Shadow Dance helps avoid all the damage from Eclipse.
* For the same reasons, Slark makes a very powerful ally for Luna when they are in the same team.
Skywrath Mage
[wiki] rating: -0.4 (winrate: 50% pickrate: 10%)Huskar
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Huskar
* Berserker's Blood works proportionate to lost health, but Huskar has a decent health pool, and the attack speed granted from Berserker's Blood powers him up.
* Skywrath Mage's armor and agility gain is very low so Huskar can outdamage him or take Skywrath Mage down with him.
Weaver
[wiki] rating: -0.4 (winrate: 50% pickrate: 3%)Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.
Huskar
* Weaver cannot Time Lapse out of Huskar's burn damage.
Silencer
[wiki] rating: -0.4 (winrate: 52% pickrate: 15%)Huskar
* Heroes with pure damage can kill Huskar when he inevitably gets low on health: Outworld Destroyer, Silencer.
Slark
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, Puck, Doom.
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Slark
* Slark's Dark Pact allows him to dispel Silencer's debuffs.
* Against a carry Silencer, Essence Shift will lower damage from both Glaives of Wisdom and his basic attack.
Anti-Mage
[wiki] rating: -0.4 (winrate: 53% pickrate: 11%)Huskar
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Slark
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: Timbersaw, Slark, Shadow Fiend, Clinkz, Bristleback Nyx Assassin, Magnus
Huskar
* Huskar does not need any mana to fight Anti-Mage as most of his skills cost HP instead. He is good counter to take away Anti-mage's farm in early to mid game. Huskar, however, struggle to kill Anti-Mage in the late game. So it is a good idea to finish the game early before Anti-Mage can farm up.
Additional:
* Huskar is not very reliant on mana to cast his spells, therefore, 
Mana Break is not very effective against him.
* Huskar also has low mana pool, he will take less damage once his mana pool is completely depleted. 
Mana Void is also ineffective against him.
* Huskar comes online earlier than Anti-Mage, and can take over the game before Anti-Mage can farm up.
Slark
* Pounce prevents Anti-Mage from using Blink, and lets him disengage from Anti-Mage if needed.
* Essence Shift allows Slark to permanently steal agility from Anti-Mage.
* Shadow Dance stops Anti-Mage from being able to fight back in a slippery situation.
Tinker
[wiki] rating: -0.4 (winrate: 56% pickrate: 11%)Huskar
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Slark
* Pounce prevents Tinker from blinking away.
* Slark frequently builds Shadow Blade, which allows him to approach Tinker unnoticed. Since Tinker's farming usually covers a significant amount of area on the map, Sentry Wards may not be cost effective.
* Shadow Dance allows Slark to detect both common and unusual wards. Eliminating common ward causes Tinker trouble farming many lanes if he does not know who may be waiting to jump on him. Slark is also uniquely able to identify some of the less common wards used by Tinker, such as those placed on the cliffs at map edges which Tinker uses to give him vision over the trees he uses to hide in.
* Slark's extremely high move speed from Shadow Dance, potentially stacked with Shadow Blade, allows him to easily follow Tinker between lanes, especially if Tinker has pushed the lanes out.
* Dark Pact dispels Laser's blind.
Puck
[wiki] rating: -0.2 (winrate: 48% pickrate: 9%)Slark
* 
Illusory Orb and 
Phase Shift allows Puck to avoid most ganking attempts.
* 
Waning Rift and 
Dream Coil makes it very hard for Slark to escape bad situations.
* Puck's abilities used together also deals significant magical nuke damage, none of which are targeted and thus cannot be avoided by Shadow Dance.
Huskar
* Bristleback, 
Centaur Warrunner, Spirit Breaker, 
Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Bristleback
[wiki] rating: 0.0 (winrate: 43% pickrate: 1%)Huskar
* The damage from Burning Spear can be reduced by turning away from Huskar.
* Bristleback can bait Huskar into using Life Break on him, then turn around and receive very little damage.
Additional:
* Bristleback's tankiness and 
Bristleback allow him to outlast Burning Spears' damage-over-time at almost any point in the game. In addition, if Huskar chooses to cast Life Break on Bristleback, Bristleback can simply turn around before it hits and receive little damage.
* 
Viscous Nasal Goo will reduce Huskar's low armor even further, and 
Quill Spray and 
Warpath will tear him down extremely quickly.
Slark
* Essence Shift allows Slark to hit bristleback freely whether on the front or back, stealing attributes and make bristleback much less tanky.
* Pounce can be used to disengage and recover loss HP with his ultimate passive, and can return to fight in a short period while bristleback is already injured and got some of his attributes stolen.
* Dark Pact makes it near impossible to keep Viscous Nasal Goo debuff on slark.
* Although Dark Pact cannot dispel Quill Spray, means Slark will still receive quill stack damage even if he uses Shadow Dance before.
* Slark builds Silver Edge in almost every game, an item that greatly counter birstleback.
Mars
[wiki] rating: 0.0 (winrate: 46% pickrate: 10%)Slark
* Bulwark blocks much of Slark's basic attack damage, even during Shadow Dance.
* Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.
* Spear of Mars and God's Rebuke can hit Slark through Shadow Dance and Depth Shroud.
* Should Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
Huskar
* Burning Spear's magical damage is very troublesome for Mars in the laning stage.
* Life Break's percentage-based magical damage bypasses Bulwark, and can also be used to jump in or out of Arena Of Blood.
Timbersaw
[wiki] rating: 0.0 (winrate: 46% pickrate: 5%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden.
Additional:
* Timbersaw can use 
Chakram as a scouting tool to find Slark if he tries to Pounce into the trees.
* None of Timbersaw's abilities require a target to be cast, allowing him to hit Slark inside Shadow Dance.
* 
Reactive Armor can be effective protection against a Slark who attacks quickly, since the strong armor and health regen cannot be stolen by Essence Shift.
* 
Timber Chain makes Timbersaw very mobile, meaning he is among the very few heroes who can actually give chase to a fleeing Slark.
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Phantom Assassin
[wiki] rating: 0.0 (winrate: 46% pickrate: 10%)Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Slark
* Heroes that can apply early pressure before Phantom Assassin has farm are massive threats: 
Axe, Viper, Meepo, 
Pugna, Slark etc.
Additional:
* Slark's Pounce allows him to close the gap on Phantom Assassin and prevent her from escaping with 
Phantom Strike.
* As a hero who typically builds Silver Edge, Slark can use it to disable Phantom Assassin's 
Blur and 
Coup de Grace, thus taking down her attack evasion and drastically reducing her damage output.
* Because Phantom Assassin is always reliant on critical strikes, Slark will have plenty of time to escape with Pounce, Shadow Dance and Silver Edge (provided that he purchased it already).
* Essence Shift can be very harmful for Phantom Assassin as losing the agility means that her physical damage will be also reduced, which can also weaken Coup de Grace if Slark manages to steal lots of agility from her.
* Overall, any attempt for Phantom Assassin to take down Slark will hurt her more than Slark.
Alchemist
[wiki] rating: 0.0 (winrate: 47% pickrate: 3%)Huskar
* Chemical Rage mitigates damage from Burning Spear.
Additional:
* 
Chemical Rage negates almost all damage from Burning Spears.
Slark
* Shadow Dance allows Slark to not be targeted by Unstable Concoction, making Alchemist stun himself and making himself vulnerable to the enemy.
* Dark Pact also allows him to just purge off the stun if timed correctly.
* Essence Shift will steal stats over long durations at a time should Alchemist lack the damage to kill Slark.
Hoodwink
[wiki] rating: 0.0 (winrate: 47% pickrate: 13%)Huskar
* Huskar’s low health play style put him at extreme risk to 
Sharpshooter's extreme damage. In addition, it breaks Berserker's Blood, nullifying Huskar's power source.
Slark
* Slark's Pounce can be used to dodge Hoodwink's abilities or lock her down.
* Shadow Dance makes Slark unhittable from 
Acorn Shot.
* Dark Pact removes all slows from Hoodwink's abilities.
* Hoodwink's already low health output is a great target for Slark's Essence Shift.
Sven
[wiki] rating: 0.0 (winrate: 48% pickrate: 2%)Slark
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
Huskar
* Heroes who can take advantage of Gods Strength being on cooldown are also not great matchups, such as 
Templar Assassin, Morphling and Huskar.
Spirit Breaker
[wiki] rating: 0.0 (winrate: 48% pickrate: 9%)Huskar
* Spirit Breaker's stuns pierce spell immunity, making him a good choice against heroes that heavily rely on Black King Bar; Huskar
Slark
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.
Lifestealer
[wiki] rating: 0.0 (winrate: 49% pickrate: 5%)Huskar
* Rage renders Lifestealer immune to the damage from Burning Spears.
* 
Feast makes Lifestealer one of few heroes that can outlast Huskar in a one-on-one fight.
Slark
* Shadow Dance allows Slark to attack Lifestealer for its duration without any way for Lifestealer to fight back, allowing him to steal his stats with Essence Shift, which also reduces Lifestealer's strength and, therefore, health pool.
* Slark can easily escape Lifestealer with Pounce, and can avoid Open Wounds with Dark Pact should Lifestealer be forced to itemize for it.
* Slark commonly buys a Silver Edge, which can break Lifestealer's Feast, severely diminishing his damage output and lifesteal.
Leshrac
[wiki] rating: 0.0 (winrate: 49% pickrate: 4%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden.
Huskar
* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.
Vengeful Spirit
[wiki] rating: 0.0 (winrate: 49% pickrate: 5%)Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.
Additional:
* Huskar struggles against heroes that output high physical damage due to his low armor. Vengeful Spirit's Wave of Terror and Vengeance Aura help increase the physical damage of her team.
Slark
* Heroes who have a high mobility (Queen of Pain, Storm Spirit, Slark, etc.).
Nyx Assassin
[wiki] rating: 0.0 (winrate: 50% pickrate: 4%)Huskar
* Nyx Assassin can reflect Life Break with 
Spiked Carapace.
Huskar
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, 
Dawnbreaker.
Warlock
[wiki] rating: 0.0 (winrate: 51% pickrate: 4%)Huskar
* Warlock Golems do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using Life Break, because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allows Warlock's team to gather their wit and retaliate.
* After using Life Break to jump in, Huskar will not have any means to escape Upheaval. Which since he is an attack-dependent hero, this will nullify his impact in fights.
Slark
* 
Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* 
Fatal Bonds and 
Shadow Word can be dispelled by Dark Pact.
Dark Seer
[wiki] rating: 0.0 (winrate: 52% pickrate: 2%)Slark
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, Dark Seer, Earthshaker, Timbersaw, Crystal Maiden.
Slark
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as 
Disruptor's Kinetic Field or Slark's Pounce.
Ursa
[wiki] rating: 0.0 (winrate: 52% pickrate: 15%)Huskar
* Jumping on Ursa with Life Break is often suicide for Huskar, as he will be immediately bursted down with 
Fury Swipes.
Additional:
* Huskar likes fights with a long duration and is usually at low health, making him vulnerable against Ursa's physical damage.
* Jumping in with Life Break against Ursa is suicide, as Enrage, Overpower, and Fury Swipes will easily shred Huskar.
Slark
* 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.
Arc Warden
[wiki] rating: 0.0 (winrate: 53% pickrate: 5%)Huskar
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Slark
* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as Slark, Riki, Earthshaker with Aghanim's Scepter, Sven with Aghanim's Scepter etc.
Additional:
* 
Flux is dispelled by Dark Pact.
* Pounce allows Slark to avoid 
Spark Wraiths.
* 
Tempest Double allows Slark to build up Essence Shift stacks, especially when it is being used for split pushing.
Lycan
[wiki] rating: 0.0 (winrate: 57% pickrate: 3%)Huskar
* Heroes with low armor and little mobility, like Huskar, 
Io, etc. will also have an unfortunate fate.
Slark
* Lycan cannot escape from a Pounce even if he uses 
Shapeshift, and has no disabling abilities to stop Slark.
Huskar
* Huskar is often played at low health to maximize the bonuses from
Berserker's Blood, and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
Berserker's Blood gives Huskar no protection against the pure damage of Culling Blade. Its attack speed bonus also means that Counter Helix will proc more often.
Burning Spears.
Berserker's Call and 
Blade Mail can be used immediately after Huskar jumps on Axe with Life Break.
Counter Helix repeatedly.
Culling Blade.
*
* Axe's tankiness and base health regeneration makes it hard for Huskar to take him down with
Additional:
*
* Huskar's high attack speed procs
* Huskar's health loss from using his abilities make him a frequent target for
Slark
* Berseker's Call catches Slark in
Shadow Dance, wasting its duration and preventing him from escaping to regenerate.
Dark Pact cannot dispel Berserker's Call, and the output damage would be returned by 
Blade Mail.
Berserker's Call forces Slark to attack him, even during Shadow Dance.
Counter Helix will hit Slark in Shadow Dance. It also triggers frequently against Slark's high attack speed provided by Essence Shift stacks.
Culling Blade finishes off Slark before he gets a chance to slip away and regenerate his health, preventing him from playing the typical hit-and-run style.
