Lifestealer
[wiki] rating: 2.0 (winrate: 48% pickrate: 5%)Omniknight
[wiki] rating: 2.0 (winrate: 47% pickrate: 1%)Axe
* Omniknight's healing prevents allies from dropping low enough for 
Culling Blade. However, it can still go through all his buffs.
* Axe also enjoys getting close to allied heroes in order to damage them with his 
Counter Helix, which can easily be punished by Purification.
Sniper
* Being mostly a physical damage dealer, Sniper's effectiveness is greatly reduced by Omniknight's 
Guardian Angel.
* Omniknight's 
Degen Aura allows him to slow sniper and catch him. Sniper has to then use some escape item.
* Omniknight can also protect an ally from being finished off by Assassinate by using 
Purification.
Viper
[wiki] rating: 2.0 (winrate: 47% pickrate: 6%)Axe
* 
Poison Attack and 
Viper Strike slows Axe significantly, and puts his 
Blink Dagger on cooldown, preventing him from initiating.
* 
Nethertoxin can break Counter Helix.
Additional:
* Nethertoxin prevents Counter Helix from triggering, which significantly lowers Axe's damage output in the early to mid game.
* Viper's various slows and damage over time prevents Axe from initiating as well as putting his Blink Dagger on cooldown.
Sniper
* Nethertoxin breaks Sniper's passives.
* Viper Strike together with Poison Attack can slow Sniper and tears through his low health and mobility.
Spectre
[wiki] rating: 2.0 (winrate: 47% pickrate: 3%)Axe
* 
Dispersion makes Spectre very durable, making it much less likely for Axe to bring her low enough for Culling Blade.
* Spectre can simply use 
Spectral Dagger to escape against an Axe gank.
Sniper
* 
Haunt instantly allows her to get up and close with Sniper, and Spectral Dagger makes it difficult to escape from her.
* Spectre outcarries Sniper in the late game, so Sniper must try to end the game early before Spectre comes online.
Additional:
* Spectre can reach him easily in the backlines with Spectral Dagger or teleport to him with Haunt.
* He is usually a fair distance away from his allies, so 
Desolate will quickly tear Sniper down.
Clockwerk
[wiki] rating: 1.6 (winrate: 52% pickrate: 7%)Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: 
Bristleback, 
Crystal Maiden, 
Batrider, 
Arc Warden, 
Winter Wyvern, 
Clockwerk
Sniper
* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.
Additional:
* Clockwerk can easily close the distance to Sniper using 
Hookshot and trap him with 
Power Cogs.
* Even though Sniper is a natural 
Hurricane Pike carrier, Sniper's low health usually means Clockwerk can finish him off with 
Battery Assault and 
Rocket Flare.
Shadow Demon
[wiki] rating: 1.6 (winrate: 47% pickrate: 2%)Sniper
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, 
Troll Warlord, 
Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Axe
* 
Disruption will save Shadow Demon's teammates from being killed by Counter Helix or Culling Blade.
* 
Soul Catcher and 
Shadow Poison can put Axe's Blink Dagger on cooldown.
* 
Demonic Purge slows Axe to a crawl, making him nearly useless after initiating. If Shadow Demon has Aghanim's Scepter, it will also break Counter Helix.
Batrider
[wiki] rating: 1.2 (winrate: 47% pickrate: 1%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit
Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Bounty Hunter
[wiki] rating: 1.0 (winrate: 54% pickrate: 10%)Sniper
* Bounty Hunter can use 
Shadow Walk to get close, and 
Jinada can do massive damage and slow down Sniper on the first attack.
* 
Track gives additional speed to Bounty Hunter and makes 
Shadow Blade useless, allowing Bounty Hunter to easily kill him with a few attacks.
Additional:
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Nyx Assassin
[wiki] rating: 1.0 (winrate: 54% pickrate: 7%)Sniper
* 
Assassinate is easy to reflect with Spiked Carapace for massive damage.
* 
Shrapnel's area damage can set up an easy stun with Spiked Carapace, especially when combined with Vendetta.
* In the early game, Sniper's low health pool and high intelligence makes him easy prey for Nyx Assassin.
Arc Warden
[wiki] rating: 1.0 (winrate: 54% pickrate: 4%)Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Sniper
* Magnetic Field's evasion completely negates Sniper's attacks unless he has True Strike.
* Sniper always positions himself far away from battles, which makes him especially vulnerable for Flux and Spark Wraith.
Axe
* Heroes who rely on fast attack speed will also trigger Counter Helix frequently: 
Faceless Void, Troll Warlord, 
Anti-Mage, 
Juggernaut, Arc Warden, 
Morphling
Additional:
* Magnetic Field doesn't provide a protection against 
Berserker's Call and Counter Helix and his high attack speed together with Tempest Double will often trigger Counter Helix.
Puck
[wiki] rating: 1.0 (winrate: 52% pickrate: 17%)Sniper
* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having Eul's Scepter of Divinity, 5 when having Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.
Ursa
[wiki] rating: 1.0 (winrate: 51% pickrate: 16%)Axe
* 
Enrage reduces the damage from 
Blade Mail and Counter Helix to a minimum, forcing Axe to play around Ursa's ultimate ability.
* 
Overpower and 
Fury Swipes tear through Axe's low armor, even if he has relatively high health.
Invoker
[wiki] rating: 1.0 (winrate: 50% pickrate: 16%)Sniper
* Invoker's arsenal of magical spells are troublesome for Sniper who has low HP and high armor, which does not benefit him much against Invoker.
* Besides magical damage, he can be disarmed and repeatedly mini-stunned with 
Cold Snap, preventing him from reacting.
* Leveling 
Quas can allow Invoker to lane effectively against Sniper despite right-click harassment.
Slardar
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)Sniper
* Slardar can use 
Guardian Sprint with Blink Dagger or Shadow Blade to get close, and 
Slithereen Crush will stun Sniper, making him vulnerable to Slardar's teammates.
* 
Corrosive Haze lowers Sniper's armor and makes Sniper's Shadow Blade useless, easily killing him with a few attacks.
Necrophos
[wiki] rating: 1.0 (winrate: 50% pickrate: 3%)Axe
* Frequent healing from 
Death Pulse and 
Mekansm makes it difficult for Axe to finish off targets with Culling Blade.
* 
Ghost Shroud's instant cast time allows Necrophos to turn ethereal before being initiated on by Berserker's Call. This prevents him from attacking Axe while taunted, thus lowering the chance to proc Counter Helix.
* Axe's high health is relatively ineffective against 
Heartstopper Aura's percentage-based health degeneration.
* 
Reaper's Scythe negates Axe's durability, and can kill him quickly after initiation.
Additional:
* Frequent healing from Death Pulse makes it difficult for Axe to finish off targets with Culling Blade.
* Reaper's Scythe negates Axe's tankiness, and can kill him quickly after initiation.
* Heartstopper Aura is effective due to Axe's high strength gain.
Storm Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 12%)Sniper
* Sniper is very squishy and cannot deal with heroes that jump onto him and lock him down. Storm Spirit closes the gap in a fight against Sniper, and Sniper has no way to escape except for some items.
* Storm Spirit can dodge Assassinate with a correctly timed Ball Lightning.
Additional:
* Storm Spirit can close the distance towards Sniper very easily with his ultimate 
Ball Lightning.
Centaur Warrunner
[wiki] rating: 1.0 (winrate: 48% pickrate: 3%)Sniper
* A Blink Dagger combined with 
Hoof Stomp can be used to catch Sniper.
* Centaur can also utilize 
Stampede to cover the distance.
* 
Double Edge can easily finish off Sniper after Centaur initiates on him.
* 
Retaliate punishes Sniper for focusing Centaur in teamfights.
Additional:
* 
Headshot and Shrapnel slow is ineffective against a team with haste (which Stampede gives).
* Commonly picked up mobility items and hasted movement during his Stampede (as well as his high health pool) make him extremely hard to kill from a distance, damaging Sniper with Retaliate and Blade Mail if he has one.
* A low health pool and no escape mechanism makes him an easy target for Centaur Warrunner's burst damage and initiation (even making his team possible initiators with Stampede).
Timbersaw
[wiki] rating: 1.0 (winrate: 48% pickrate: 8%)Axe
* 
Whirling Death reduces Axe's strength by 15%, which makes him less durable, especially from early game. It's also stackable.
* Blade Mail are not effective against attribute changes, and 
Timber Chain can wait out Blade Mail's duration to wear off.
* 
Reactive Armor makes it harder for Axe to finish off Timbersaw with Culling Blade.
* 
Chakram disarms Timbersaw, which makes Axe's Counter Helix useless against him.
* All Timbersaw skills deal pure damage, which bypass Axe's high armor or bonus armor from Berserker's Call.
Additional:
* Whirling Death reduces Axe's strength by 15%, making him much less durable, especially in the early game. It is also stackable.
* Axe's Blade Mail is ineffective against attribute changes, and Timbersaw's mobility with Timber Chain means he can wait out Blade Mail's duration.
* Reactive Armor's armor and regeneration makes it much harder for Axe to finish Timbersaw with Culling Blade.
* Chakram disarms Timbersaw, making Counter Helix less effective.
Legion Commander
[wiki] rating: 1.0 (winrate: 47% pickrate: 11%)Sniper
* Sniper's low mobility and lack of defensive abilities makes him an easy gank target for the entire game, especially if Blink Dagger is picked up.
Ember Spirit
[wiki] rating: 1.0 (winrate: 47% pickrate: 9%)Sniper
* Ember Spirit can close the distance between Sniper easily with his 
Activate Fire Remnant and further keep Sniper in place with 
Searing Chains.
* With the help of 
Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
Pudge
[wiki] rating: 1.0 (winrate: 46% pickrate: 19%)Sniper
* Pudge's 
Meat Hook allows him to bring Sniper in the middle of any fight, and the pure damage does well against his high armor and low health.
* 
Dismember can lock Sniper down, which makes him highly vulnerable and gives enough time for Pudge to kill him alone.
Additional:
* Sniper has a low health pool and strength gain, making him vulnerable to Pudge's magical and pure damage.
* Sniper usually likes to deal damage away from the fight, and Meat Hook is capable of bringing him to the front lines.
* Assassinate won't do much damage against Pudge because of his high strength gain and the strength bonuses from Flesh Heap.
Bane
[wiki] rating: 0.6 (winrate: 54% pickrate: 3%)Sniper
* 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.
Chen
[wiki] rating: 0.6 (winrate: 52% pickrate: 0%)Axe
* Hand of God and Divine Favor make it hard for 
Axe to finish off allies with Culling Blade.
Sand King
[wiki] rating: 0.6 (winrate: 51% pickrate: 10%)Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress,...
Templar Assassin
[wiki] rating: 0.6 (winrate: 51% pickrate: 5%)Sniper
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: 
Lich, 
Lina, Sniper, 
Outworld Destroyer 
Zeus
Gyrocopter
[wiki] rating: 0.6 (winrate: 50% pickrate: 5%)Axe
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe, 
Dragon Knight, 
Sven.
Lion
[wiki] rating: 0.6 (winrate: 50% pickrate: 17%)Axe
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, 
Lion.
Phoenix
[wiki] rating: 0.6 (winrate: 50% pickrate: 9%)Axe
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, 
Mars.
Additional:
* 
Sun Ray allows Phoenix to heal any allies caught in Berserker's Call, while burning away Axe's high HP at the same time.
* 
Icarus Dive and 
Fire Spirits puts Axe's Blink Dagger on cooldown.
* Axe's slow attack speed makes it difficult for him to destroy 
Supernova on his own.
Treant Protector
[wiki] rating: 0.6 (winrate: 49% pickrate: 5%)Sniper
* Clinkz, Sniper, 
Lone Druid, Troll Warlord, 
Legion Commander and 
Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Winter Wyvern
[wiki] rating: 0.6 (winrate: 49% pickrate: 7%)Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Earth Spirit
[wiki] rating: 0.6 (winrate: 48% pickrate: 10%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, 
Earth Spirit, 
Io, 
Nature's Prophet, 
Pangolier, 
Puck, 
Queen of Pain and most notably Riki.
Enchantress
[wiki] rating: 0.6 (winrate: 46% pickrate: 1%)Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Vengeful Spirit
[wiki] rating: 0.6 (winrate: 45% pickrate: 3%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit
Pugna
[wiki] rating: 0.4 (winrate: 53% pickrate: 4%)Axe
* 
Decrepify can be used on allies to prevent them from attacking Axe and triggering Counter Helix during Berserker's Call. He can also cast it on Axe to prevent anyone from attacking him.
* 
Life Drain can be used to heal himself or allies caught in Berserker's Call, preventing them from dropping low enough for Axe to kill them with Culling Blade.
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: 
Witch Doctor, Crystal Maiden, 
Shadow Shaman, 
Pugna
Additional:
* Sniper's huge range makes him an unviable target to use Life Drain on, forcing Pugna to risk playing out of position to use it on Sniper.
* Sniper's Shrapnel can be used to provide vision on Nether Ward, and his range allows him to easily take it out.
* A clumsy Pugna may accidentally boost Sniper's Shrapnel and Assassinate damages if he recklessly uses Decrepify on himself or his allies.
Bloodseeker
[wiki] rating: 0.4 (winrate: 51% pickrate: 4%)Sniper
* Sniper is suspectible to being ganked by Bloodseeker, who can easily kill Sniper due to his lack of mobility and escape mechanisms.
* Even if Sniper builds mobility items, Bloodseeker can prevent and even punish Sniper from/for using them with 
Rupture; Sniper is forced to stand still with Shadow Blade, while Hurricane Pike and Blink Dagger deals damage if he attempts to use them while Ruptured.
Additional:
* Sniper's lack of mobility and escape mechanisms makes him one of the easier heroes for Bloodseeker to gank.
Axe
* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: Dragon Knight, Axe
Spirit Breaker
[wiki] rating: 0.4 (winrate: 51% pickrate: 8%)Sniper
* Spirit Breaker can charge towards Sniper from anywhere on the map with 
Charge of Darkness.
* 
Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with 
Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.
Axe
* Heroes who continue dealing damage while being stunned: Luna, 
Razor, Axe, Bristleback, 
Leshrac,
Jakiro
[wiki] rating: 0.4 (winrate: 50% pickrate: 9%)Axe
* Axe is a hero that is very vulnerable against magical nuke damage and disables, Jakiro is perfect against him with all of his spells.
Additional:
* 
Ice Path neutralizes initiation attempts with Berserker's Call, and its long area of effect discourages follow-ups from Axe's teammates.
* Ice Path serves as a large obstacle to stop Axe from chasing down fleeing stragglers to kill with Culling Blade.
* Jakiro's many damage-per-second skills prevent Axe from initiating with his Blink Dagger.
Sniper
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, Sniper, 
Tinker, 
Windranger.
Tusk
[wiki] rating: 0.4 (winrate: 50% pickrate: 13%)Sniper
* 
Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH! damage can easily kill Sniper instantly due to his low health.
Axe
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, 
Night Stalker, 
Centaur Warrunner, Wraith King and more.
Venomancer
[wiki] rating: 0.4 (winrate: 50% pickrate: 5%)Axe
* Venomancer's slows and magical damage-over-time work well against Axe's complete lack of mobility.
* 
Plague Ward is especially useful for slowing down Axe, and revealing him before he initiates, as well as putting his Blink Dagger on cooldown.
Additional:
* Venomancer's slows and magical damage-over-time work well against Axe's complete lack of mobility.
* Plague Wards is especially useful for slowing down Axe, and revealing him before he initiates, as well as putting his Blink Dagger on cooldown.
* For the same reasons, Venomancer is a good ally for Axe when the situation is reversed.
Sniper
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.
Doom
[wiki] rating: 0.4 (winrate: 44% pickrate: 2%)Axe
* 
Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Axe more than most normal attacks, negating some of his durability.
* Doom can pick up several different abilities from neutral creeps using 
Devour, some of which can be annoying to Axe.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom's naturally low attack speed makes Counter Helix less likely to proc, and his high base health allows him to take a few Helixes with no danger.
* 
Doom makes Axe less disruptive, preventing him from using his skills or items. With Aghanim's Scepter, Counter Helix is also disabled, making him effectively useless for a lengthy duration.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Axe.
* Doom has low attack speed because of his high Base-Attack-Time, poor agility gain and limited attack-speed granting items which are commonly built. This means Doom will trigger Counter Helix less often and thus is an unideal target for initiation.
* Doom has naturally high HP so it takes longer for Doom to be brought down to the killing threshold of Culling Blade.
* Axe is highly reliant on his abilities and items to be effective during a fight. Without the usage of Berserker's Call and Blink Dagger due to Doom, Axe offers very little in the way of damage, effectively removing him from a fight.
Sniper
* Heroes who Sniper can kite: Sven, Wraith King, 
Kunkka, 
Doom, 
Tidehunter, 
Underlord, Troll Warlord, and etc.
Additional:
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
Shadow Fiend
[wiki] rating: -2.0 (winrate: 46% pickrate: 18%)Axe
* Berserker's Call and Counter Helix allow Axe to kill Shadow Fiend if he stands too close to a creep wave.
* 
Battle Hunger is very strong against Shadow Fiend in the early game because Shadow Fiend's low attack damage makes it hard for him to get last hits.
* Axe's naturally high strength and health regeneration will be enough to tank a lot of Shadow Fiend's damage in the early game.
Sniper
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his 
Shadowraze.
* Assassinate can be used to cancel Shadow Fiend's 
Requiem of Souls if he is not a target.
Additional:
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* 
Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his Shadowrazes.
Troll Warlord
[wiki] rating: -1.6 (winrate: 52% pickrate: 12%)Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Shrapnel and Headshot allows Sniper to kite Troll Warlord effectively.
* Take Aim together with certain items such as Hurricane Pike allow Sniper to sit and fire at Troll Warlord from a safe distance.
Axe
* Troll Warlord has significant attack speed due to Fervor and Battle Trance, giving Axe a higher chance to proc Counter Helix and seriously injure Troll Warlord due to his relatively low maximum health.
* Axe often purchases Blade Mail, which can help Axe turn Troll Warlord's farm and high physical damage against him. The bonus armor provided by Berserker's Call means that Troll Warlord will take a lot more damage than Axe.
* Culling Blade is still capable of killing Troll Warlord during Battle Trance if his HP is low enough.
Additional:
* Troll Warlord's high attack speed means Counter Helix will proc extremely frequently even without creeps near him. This, combined with a Blade Mail means Axe can easily solo kill Troll Warlord even in later stages of the game.
* 
Battle Trance does not save Troll Warlord from a Culling Blade.
Visage
[wiki] rating: -1.6 (winrate: 54% pickrate: 1%)Sniper
* Heroes with long ranged attacks or abilities can harass Visage from afar like 
Phoenix and Sniper.
Axe
* Axe can Berserker's Call into a flock of Familiars, proccing Counter Helix and killing them off.
* Familiars' very fast attacks will proc Counter Helix, receiving full damage due to their low attack range.
Drow Ranger
[wiki] rating: -1.4 (winrate: 47% pickrate: 4%)Axe
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Axe
* Berserker's Call forces Drow Ranger to attack Axe up close, disabling her Marksmanship bonus.
* Counter Helix occurs more often with Drow Ranger's high attack speed.
* Culling Blade is a dangerous ability against a low health hero like Drow Ranger.
Sniper
* Take Aim allows Sniper to outrange Drow Ranger and deal damage at her without much fear of retaliation
* Sniper can slow down Drow Ranger with Shrapnel, and both Shrapnel and Assassinate makes it easier for Sniper's team to track and take her down
Additional:
* Somewhat like Medusa, Drow Ranger is a fairly immobile hero that hopes to be able to attack without dying. Sniper should outrange her.
* Shrapnel and Assassinate provides vision over her, and slows her down, making it easier for you team to focus on taking her down
* Be careful however that if she starts attacking you, she packs a bigger punch than you thanks to 
Marksmanship.
Monkey King
[wiki] rating: -1.2 (winrate: 50% pickrate: 16%)Sniper
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: 
Bloodseeker, 
Treant Protector with Eyes In The Forest, Sniper, Weaver
Axe
* Heroes that can keep Monkey King stunned for a long time can pose a threat: Axe, Centaur Warrunner.
Shadow Shaman
[wiki] rating: -1.2 (winrate: 52% pickrate: 16%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Axe
* Pudge, Legion Commander and Axe will make the match a living hell for you, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt your channeling, Legion being especially problematic, as she can use 
Press the Attack on an ally who is hexed as well.
Kunkka
[wiki] rating: -1.0 (winrate: 44% pickrate: 3%)Sniper
* With his Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
Grimstroke
[wiki] rating: -1.0 (winrate: 47% pickrate: 12%)Sniper
* Sniper's position in the far back line makes him unlikely to be hit by any of Grimstroke's abilities during teamfights.
* Sniper is relatively unaffected by the silence from Phantom's Embrace.
* Sniper's long range and fast projectile speed allows him quickly to destroy any Phantoms attacking his allies.
Dazzle
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Axe
* Culling Blade ignores the protection from 
Shallow Grave, and will kill any target whose health is low enough. This makes Axe one of the hardest counters to Dazzle, and he neutralizes one of Dazzle's most important abilities.
Additional:
* Culling Blade kills any target under the health threshold, even through Shallow Grave.
Earthshaker
[wiki] rating: -1.0 (winrate: 49% pickrate: 12%)Sniper
* Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.
Additional:
* Sniper is able to kite Earthshaker with his very long range.
* Sniper can dodge Earthshaker's stuns like 
Fissure and 
Enchant Totem with mobility items such as Blink Dagger and Shadow Blade/
Silver Edge.
* Sharpnel can be used to cancel Earthshaker's Blink Dagger and preventing effective use of his 
Echo Slam in a majority of situations.
Silencer
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Sniper
* Sniper is a pure right click carry with a very long range, making it hard for Silencer to cast any of his skills on him in lane. During team-fights, 
Global Silence has little impact on Sniper.
Additional:
* Due to Sniper having a such a long range, he will rarely get hit by any of Silencer's spells.
* Global Silence will not hinder Sniper much as other heroes since most of his damage output comes from his attacks.
Io
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Take Aim and Assassinate allow Sniper to reach Io even if it stays in the backline.
Axe
* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer
Luna
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Sniper
* Sniper usually sits at the back and it's hard for Luna to get close to him to attack.
* Due to Sniper's Shrapnel and his long range, Luna has a hard time taking high ground despite her Moon Glaives being fantastic for taking Barracks and buildings.
Dark Seer
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Sniper
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
Abaddon
[wiki] rating: -1.0 (winrate: 52% pickrate: 5%)Axe
* Culling Blade ignores 
Borrowed Time should Abaddon's health falls under the threshold.
Additional:
* Culling Blade's instant kill is not prevented by Borrowed Time should Abaddon's health falls below the threshold.
Chaos Knight
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Axe
* Berserker's Call and Counter Helix makes short work of Chaos Knight's 
Phantasms.
Additional:
* Berserker's Call allows Axe to lock down Chaos Knight and his illusions.
* Counter Helix combined with Blade Mail clears illusions out in no time.
Dark Willow
[wiki] rating: -1.0 (winrate: 52% pickrate: 7%)Axe
* Berserker's Call forces Dark Willow to attack, cancelling Shadow Realm.
Huskar
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Axe
* Berserker's Call and Blade Mail can be used immediately after Huskar jumps on Axe with Life Break.
* Huskar's high attack speed procs Counter Helix repeatedly.
* Huskar's health loss from using his abilities make him a frequent target for Culling Blade.
Additional:
* 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.
* Axe's tankiness and base health regeneration makes it hard for Huskar to take him down with 
Burning Spears.
Juggernaut
[wiki] rating: -1.0 (winrate: 52% pickrate: 19%)Axe
* Berserker's Call pierces spell immunity, making a Blade Fury teleport escape impossible. It's very useful against 
Omnislash as well.
* Juggernaut's low base health and high attack speed causes him to take a lot of damage from the pure damage of Counter Helix.
* Axe is a common Blade Mail and Blink Dagger carrier making him a very big potential threat before Juggernaut get his items.
Razor
[wiki] rating: -1.0 (winrate: 54% pickrate: 6%)Sniper
* His increased attack range makes it very hard to get close enough for Static Link, Eye of the Storm and Razor's own attacks.
* Headshot procs will slow Razor heavily regardless of Storm Surge, as it will knock him back for a brief duration.
Sven

* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Tiny
[wiki] rating: -0.6 (winrate: 45% pickrate: 5%)Sniper

Meepo
[wiki] rating: -0.6 (winrate: 45% pickrate: 1%)Axe
* Melee heroes who rely on summons, illusions or clones will trigger Counter Helix more often, thus taking more damage: Meepo, 
Lycan, 
Chaos Knight, Phantom Lancer
Additional:
* The combination of Counter Helix and Berserker's Call can disable multiple Meepos and deal heavy area damage.
* Axe's natural high survivability makes it difficult to burst him down with Poof or chip away at his health with Ransack.
Witch Doctor
[wiki] rating: -0.6 (winrate: 47% pickrate: 13%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Techies
[wiki] rating: -0.6 (winrate: 48% pickrate: 8%)Axe
* Techies struggles early game against heroes with naturally large strength and health regeneration such as Pudge, Axe or 
Ogre Magi, as the player is forced to lay down more mines than usual to kill these bulkier heroes.
Pangolier
[wiki] rating: -0.6 (winrate: 49% pickrate: 12%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Axe
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, 
Beastmaster, 
Enigma, 
Magnus, Pudge, Batrider, 
Bane, Winter Wyvern
Sniper

Templar Assassin, Arc Warden
Void Spirit
[wiki] rating: -0.6 (winrate: 50% pickrate: 13%)Axe

Ursa,

* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.

Underlord
[wiki] rating: -0.6 (winrate: 51% pickrate: 7%)Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of Firestorm and Pit of Malice as well as Atrophy Aura range.
Magnus
[wiki] rating: -0.4 (winrate: 44% pickrate: 4%)Sniper
* Squishy core heroes (Shadow Fiend, Sniper, etc)
Sniper
* Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Mars
[wiki] rating: -0.4 (winrate: 48% pickrate: 16%)Sniper
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, Anti-Mage, 
Broodmother, Drow Ranger, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Axe
* Berserker's Call forces Mars to face in the direction choosen.
* Counter Helix is a much stronger lane trader than Spear of Mars.
Anti-Mage
[wiki] rating: -0.4 (winrate: 49% pickrate: 13%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Axe
* Berserker's Call prevents Anti-Mage from escaping with Blink, and works well with Blade Mail against Anti-Mage's relatively low health.
* Counter Helix deals pure damage, ignoring the protection from Counterspell.
* Counter Helix will trigger even if Axe's depleted of mana, which will make Anti-Mage take more damage than he's dealing.
* Axe's low mana pool makes him a bad target for using Mana Void.
* Axe's high base health regeneration allows him to dominate the lane against Anti-Mage, especially with a support.
Additional:
* Berserker's Call is one of the most reliable ways to lock down Anti-Mage, preventing him from 
Blinking away.
* Anti-Mage's high attack speed, along with illusions from 
Manta Style, triggers Counter Helix continuously.
* Axe's low mana pool and high health pool makes 
Mana Void deal very little damage to Axe.
Disruptor
[wiki] rating: -0.4 (winrate: 49% pickrate: 9%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit
Sniper
* Sniper can kill Disruptor while he is trapped by Kinetic Field from a long range.
* Sniper generally stays in the back, making it hard for Disruptor to cast any of his skills on him in lane.
Oracle
[wiki] rating: -0.4 (winrate: 51% pickrate: 10%)Sniper
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Axe
* False Promise will not save an ally from Culling Blade if their health is low enough.
* Fate's Edict, offensively or defensively, does little to protect Oracle's allies from the majority of Axe's damage.
Windranger
[wiki] rating: -0.4 (winrate: 51% pickrate: 16%)Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
Axe
* Windrun does not provide protection against Counter Helix and Berserker's Call. Her fast attack speed with Focus Fire will also quickly trigger Counter Helix multiple times.
Enigma
[wiki] rating: -0.4 (winrate: 55% pickrate: 8%)Axe
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heros like; 
Spirit Breaker, Legion Commander, Axe, Puck, and 
Slardar
Sniper
* Sniper has a very long range, so it is rare that Enigma can catch him in a 
Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with the level 20 talent.
* Enigma's Eidolons from 
Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with 
Maelstrom/
Mjollnir.
Additional:
* Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small Black Hole AoE. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation, assuming Enigma does not have Aeon Disk.
Faceless Void
[wiki] rating: 0.0 (winrate: 41% pickrate: 3%)Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.
Axe
* Heroes with gap closing abilities will be easy targets for Berserker's Call: Phantom Assassin, Faceless Void, Slark, Chaos Knight, Morphling, Queen of Pain
Nature's Prophet
[wiki] rating: 0.0 (winrate: 44% pickrate: 5%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Axe
* Heroes that have AoE damage: Lina, 
Keeper of the Light, 
Timbersaw, Leshrac, Bristleback, Axe
Additional:
* Berserker's Call and Counter Helix will still hit targets inside of a defensive 
Sprout.
* Counter Helix clears treants in no time.
* Nature's Prophet's low damage is unlikely to hurt Axe until the very late game.
* Nature's Prophet's low mobility makes him very easy for Axe to chase down or initiate on, especially when affected by Battle Hunger.
Phantom Assassin
[wiki] rating: 0.0 (winrate: 45% pickrate: 16%)Sniper
* 
Phantom Strike allows her to jump on Sniper with increased attack speed.
* 
Coup de Grace and 
Desolator shreds Sniper's low health and armor.
* 
Blur can be activated to get within Phantom Strike's range, surprising Sniper before he has a chance to react. Its passive also reduces Sniper's overall effectiveness against Phantom Assassin, provided he hasn't purchased a 
Monkey King Bar.
Additional:
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Axe
* Phantom Strike's extra attack speed causes Phantom Assassin to proc Counter Helix more often. Using it on Axe also makes Phantom Assassin an easy target for a counter-initiation with Berserker's Call and Blade Mail.
* Most of Axe's abilities pierce 
Black King Bar, allowing him to lock down Phantom Assassin at any time.
* Berserker's Call greatly reduces Phantom Assassin's ability to crit hard against Axe, and may cause her to kill herself when used with Blade Mail.
Additional:
* Jumping in with Phantom Strike makes Phantom Assassin an exceptionally easy target for Berserker's Call.
* The bonus attack speed from Phantom Strike also means that Phantom Assassin will proc Counter Helix numerous times.
* Black King Bar is generally useless against Axe's abilities and item build, as Black King Bar doesn't prevent Axe from finishing Phantom Assassin off with Culling Blade. It also doesn't work against Berserker's Call and Counter Helix.
* Blade Mail is an item that Axe purchases every game, and it can be used to turn Phantom Assassin's critical strikes against herself. The situation becomes even worse if she's affected by Berserker's Call, as she has no way to stop attacking.
Medusa
[wiki] rating: 0.0 (winrate: 45% pickrate: 2%)Axe
* Mystic Snake can harass Axe in lane and drain his small mana pool.
* Mana Shield reduces the effectiveness of Counter Helix.
* Stone Gaze makes it very difficult for Axe to pursue.
Sniper
* Medusa is a fairly immobile hero that deals damage around her with 
Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her 
Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
Additional:
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Bristleback
[wiki] rating: 0.0 (winrate: 46% pickrate: 8%)Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Axe
* Axe forces Bristleback to turn around with Berserker's Call, allowing allies to attack him without fear of his passive.
Morphling
[wiki] rating: 0.0 (winrate: 46% pickrate: 12%)Sniper
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
* Sniper's low health also makes him extremely vulnerable to Morphling's 
Ethereal Blade and Adaptive Strike combo.
Axe
* Jumping on Axe from 
Waveform he will be an easy target for a counter-initiation with Berserker's Call.
* Morphling is often played at low health to maximize the bonuses from 
Attribute Shift (Agility Gain), and also because his abilities cost health to use. This makes him especially vulnerable to Culling Blade.
* However, Morphling is common 
Linken's Sphere carrier to block Culling Blade forces Axe to use Battle Hunger to pop the Spell Block first.
* Attribute Shift (Agility Gain) gives Morphlig no protection against the pure damage of Culling Blade. Its attack speed bonus also means that Counter Helix will proc more often.
Terrorblade
[wiki] rating: 0.0 (winrate: 46% pickrate: 4%)Sniper
* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage by quite a bit.
* Terrorblade is a far harder carry than Sniper is, so a well-farmed Terrorblade can easily defeat a Sniper.
Axe
* Terrorblade's low base health and lack of mobility make him an easy target for Axe to initiate on, and kill.
* Counter Helix will trigger from, and destroy many of Terrorblade illusions.
Additional:
* Berserker's Call and Counter Helix together can be devastating to Terrorblade, especially if Terrorblade has a lot of illusions. Their high attack speed will trigger Counter Helix a lot, and the pure damage will quickly slice through Terrorblade's low health and kill his illusions.
* Culling Blade finishes off Terrorblade before he has the chance to Sunder due to his low health in the early to mid game.
Queen of Pain
[wiki] rating: 0.0 (winrate: 47% pickrate: 9%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Axe
* Heroes with gap closing abilities will be easy targets for Berserker's Call: Phantom Assassin, Faceless Void, Slark, Chaos Knight, Morphling, Queen of Pain
Additional:
* Berserker's Call prevents Queen of Pain from escaping with Blink and also pierces her Black King Bar.
* Due to her fast attack speed from Mjollnir, it will quickly trigger Counter Helix.
* Culling Blade finish off Queen of Pain's low health pool before she gets a chance to escape, preventing her from playing the hit-and-run style often associated with Queen of Pain.
Riki
[wiki] rating: 0.0 (winrate: 48% pickrate: 5%)Sniper
* Sniper has no natural escape and relies on his range and slows to keep himself safe, which you can bypass with Blink Strike and quickly deplete his miniature HP pool.
Axe
* Axe can disable Cloak and Dagger's invisibility with Berserker's Call, which forces Riki to attack him at a very bad angle.
* Axe has a very high HP pool, making it hard for you to kill him before you get big items - that is if you survive engaging him. Counter Helix ignores your armor and goes straight for your tiny HP pool, totally ignoring Smoke Screen.
* Axe is a natural buyer of Blade Mail and Riki players generally do not buy lifesteal, causing you to kill yourself when attacking due to your tiny HP pool.
Slark
[wiki] rating: 0.0 (winrate: 48% pickrate: 13%)Sniper
* Slark is a natural Shadow Blade carrier, and with 
Pounce Sniper has no opportunity to escape or react.
* With 
Essence Shift and 
Shadow Dance, Slark will easily win a fight against Sniper.
Additional:
* Sniper is one of the most gankable heroes in the game, and has no defenses when Pounced on by Slark.
Axe
* Berseker's Call catches Slark in Shadow Dance, wasting its duration and preventing him from escaping to regenerate.
* Unlike most disables, 
Dark Pact cannot dispel Berserker's Call, and the output damage would be returned by Blade Mail.
Additional:
* Berserker's Call forces Slark to attack him, even during Shadow Dance.
* Counter Helix will hit Slark in Shadow Dance, with pure damage. It also triggers frequently against Slark's high attack speed after having stolen agility with Essence Shift.
* Culling Blade finishes off Slark before he gets a chance to slip away and regenerate his health, preventing him from playing the hit-and-run style often associated with Slark.
Crystal Maiden
[wiki] rating: 0.0 (winrate: 49% pickrate: 14%)Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Undying
[wiki] rating: 0.0 (winrate: 50% pickrate: 4%)Axe
* 
Decay's stacking strength reduction makes Axe much less dominant in lane.
* 
Tombstone's zombies take no damage from Counter Helix, and will continuously put Axe's Blink Dagger on cooldown until dealt with.
Sniper
* Sniper can easily destroy Tombstone from long range.
Weaver
[wiki] rating: 0.0 (winrate: 51% pickrate: 13%)Sniper
* 
Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of 
The Swarm and Desolator tears through Sniper's low armor.
Axe
* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use 
Time Lapse. It can also catch Weaver in Shukuchi.
* Weaver's high attack speed, along with high attack damage from 
Geminate Attack, triggers Counter Helix continuously and the output damage would be returned by Blade Mail.
Additional:
* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Due to his fast attack speed from Geminate Attack and items that give attack speed, Counter Helix will activate a lot, and the damage would be returned by Blade Mail, which hurts Weaver far more than it hurts Axe.
* Culling Blade can finish off Weaver's low health pool before he escapes with Shukuchi and Time Lapse.
* Battle Hunger is a good tool to pop Weaver's Linken's Sphere due to its low cooldown.
Outworld Destroyer
[wiki] rating: 0.0 (winrate: 51% pickrate: 13%)Axe
* Outworld Destroyer's pure and magical damage is particularly effective against Axe.
* 
Astral Imprisonment is an excellent way to defend against an initiating Axe.
* 
Sanity's Eclipse deals high damage to Axe due to his low mana pool.
Additional:
* Berserker's Call bonus armor doesn't block Arcane Orb's pure damage.
* Astral Imprisonment can be used to prevent an ally or Outworld Devourer himself from an Axe initiation.
* Axe's low mana means he's susceptible to a powerful Sanity's Eclipse.
Sniper
* As Outworld Devourer has short cast ranges, a short attack range, and no gap-closing abilities, Sniper can kite and harass Outworld Devourer in lane with his long range and zone him out in fights. The continuous area damage from Shrapnel also prevents Astral-Blink escapes.
Phantom Lancer
[wiki] rating: 0.0 (winrate: 51% pickrate: 10%)Sniper
* 
Phantom Rush grants Phantom Lancer the mobility to close in the distance between Sniper.
* Phantom Lancer can dispel Sniper's Assassinate easily with 
Doppelganger and causes confusion to Sniper with the latter effect of creating an additional of 2 illusions.

Juxtapose easily can overwhelm Sniper, as his damage is mostly single-targeted.
Axe
* Berserker's Call helps locks down Phantom Lancer in a group of illusions.

* Phantom Lancer's low health in the early game makes him a frequent target for Culling Blade.

* Phantom Lancer's low early game health makes him an easy target for Culling Blade.
Broodmother
[wiki] rating: 0.0 (winrate: 53% pickrate: 2%)Sniper
* Sniper is completely helpless against Incapacitating Bite, and can be seriously damaged by Spiderlings in lane.
Axe
* Berserker's Call can catch Broodmother in her web, as well as groups of spiderlings. This is particularly effective when Broodmother attempts to push towers with her spiderlings.
* Counter Helix destroys spiderlings very quickly, and earns Axe a good deal of gold.
Additional:
* Berserker's Call forces Broodmother and her spiderlings to attack, allowing for large amounts of pure damage to be done through Counter Helix.
Naga Siren
[wiki] rating: 0.0 (winrate: 54% pickrate: 2%)Sniper
* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Axe
* Axe will destroy her illusions by proccing Counter Helix more often due to him being hit by more attacks.
Lycan
[wiki] rating: 0.0 (winrate: 54% pickrate: 3%)Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Axe

Additional:
* Berserker's Call can keep Lycan in place during his Shapeshift even through Black King Bar.
* Counter Helix is very effective against Lycan because of his summons.
* Culling Blade will prevent Lycan from running away with Shapeshift when he drops low.
Sniper
* Lifestealer can close the distance to Sniper by using
Infest on a fast or durable creep to tank Sniper's damage.
Open Wounds will reduce Sniper's mobility heavily, and 
Rage's attack speed bonus helps in taking down Sniper.
*
Axe
*
Feast's lifesteal makes it nearly impossible for Axe to initiate and bring Lifestealer's health low enough for Culling Blade, even with many procs of Counter Helix.
Feast's healing is calculated as a percentage of a target's max health, turning Axe's high health against him. This allows Lifestealer to trade against Axe much better than most other heroes.
Culling Blade and also deals high damage to Axe due to his naturally high health.
Berserker's Call.
*
Additional:
* Feast makes it impossible to put Lifestealer's health for a
* However, Lifestealer's Rage can be pierced by
