Pugna
[wiki] rating: 2.0 (winrate: 53% pickrate: 4%)Lifestealer
[wiki] rating: 2.0 (winrate: 48% pickrate: 5%)Tinker
* 
Rage will dispel Laser's blind and turns him spell immune for the duration so Tinker cannot damage him.
* 
Feast will quickly bring down Tinker due to being so fragile.
Additional:
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest any mobile hero (teams usually pick one against Tinker), which ensures that Tinker will die if he is caught.
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.
Additional:
* Feast makes it impossible to put Lifestealer's health for a 
Culling Blade and also deals high damage to Axe due to his naturally high health.
* However, Lifestealer's Rage can be pierced by 
Berserker's Call.
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.
Tinker
* His global teleportation with 
Boots of Travel and 
Rearm is easily countered with 
Haunt, and Spectre can reach him anywhere on the map.
* He is squishy, and if alone 
Desolate will kill him very fast.
* 
Laser's blind isn't reliable, since Desolate cannot miss.
Doom
[wiki] rating: 2.0 (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.
Tinker
* Tinker is heavily reliant on casting his spells and Doom can disable all of his abilities and items. An Aghanim's Scepter only makes it harder for Tinker to survive.
Additional:
* Tinker is heavily dependent on active abilities and Doom prevents him from using any of them.
Clockwerk
[wiki] rating: 1.6 (winrate: 52% pickrate: 7%)Tinker
* Rocket Flare can find Tinker if he blinks into the treeline, and Hookshot will prevent him from teleporting out.
* Battery Assault makes Tinker unable to Rearm by stunning him repeatedly.
Additional:
* Clockwerk can easily catch a split pushing Tinker with his 
Hookshot and prevent him from escaping with 
Power Cogs and 
Battery Assault.
* He can find a Tinker hiding in trees with his 
Rocket Flare.
* Clockwerk usually buys a 
Blade Mail, which does lots of damage to Tinker if he gets hit by his abilities (especially March of the Machines).
Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: 
Bristleback, 
Crystal Maiden, 
Batrider, 
Arc Warden, 
Winter Wyvern, 
Clockwerk
Shadow Demon
[wiki] rating: 1.6 (winrate: 47% pickrate: 2%)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.
Tinker
* Heroes that can gain vision over trees to catch Tinker: 
Invoker, 
Shadow Demon, Batrider
Batrider
[wiki] rating: 1.2 (winrate: 47% pickrate: 1%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider
Axe
* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk
Nyx Assassin
[wiki] rating: 1.0 (winrate: 54% pickrate: 7%)Tinker
* His whole skillset acts like a counter to Tinker:
* 
Impale prevents Tinker from blinding Nyx Assassin or fighting back, while giving Nyx' allies time to catch up to Tinker's position.
* 
Mana Burn generally deals more damage to intelligence based heroes like Tinker
* 
Spiked Carapace can stun Tinker at a moment of Nyx Assassin's choosing if March of the Machines has been cast. It is also quite easy to time Spiked Carapace against Heat Seeking Missiles.
* 
Vendetta allows Nyx to approach Tinker in the trees or wait for him in common hiding spots and deal heavy damage to his low armor.
Additional:
* 
March of the Machines and 
Heat-Seeking Missile allow easy Spiked Carapace stuns.
* As a fragile hero that relies on mana and intelligence items, Tinker is vulnerable to Mana Burn.
* Nyx Assassin's stuns can interrupt Rearm and leave Tinker helpless.
Beastmaster
[wiki] rating: 1.0 (winrate: 53% pickrate: 6%)Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Night Stalker
[wiki] rating: 1.0 (winrate: 52% pickrate: 5%)Tinker
* Night Stalker can easily find Tinker in the trees during 
Dark Ascension.
* 
Void's mini-stun will stop Rearm and Boots of Travel.
* 
Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
Additional:
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
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.
Undying
[wiki] rating: 1.0 (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.
Venomancer
[wiki] rating: 1.0 (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.
Silencer
[wiki] rating: 1.0 (winrate: 49% pickrate: 5%)Tinker
* As Tinker relies heavily on his spells to be effective, 
Last Word and 
Global Silence will render him largely useless.
* 
Arcane Curse effectively prevents Tinker from casting spells during its duration, as he will otherwise suffer heavy damage.
* 
Glaives of Wisdom deal pure damage, which make quick work of fragile heroes like Tinker.
Additional:
* Silencer can stop Rearm, preventing Tinker from spamming his abilities/items or escaping.
Storm Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 12%)Tinker
* Storm Spirit destroys trees and ignores impassable terrains with Ball Lightning, rendering them dangerous places for Tinker to hide within.
* Ball Lightning disjoints projectile from Heat-Seeking Missile and damage from March of the Machines.
* Electric Vortex prevents Tinker from teleporting away, and Static Remnant and Overload can easily burst him down.
Additional:
* He can easily catch Tinker in the trees with 
Ball Lightning and kill him with 
Orchid Malevolence and his abilities, which deal both physical and magical damage, making them difficult for Tinker to itemize against.
Earth Spirit
[wiki] rating: 1.0 (winrate: 48% pickrate: 10%)Tinker
* Tinker is an easy target for Earth Spirit to initiate on. He likes to split push lanes once he acquires Boots of Travel and Earth Spirit can jump him with his Rolling Boulder and disable him to buy enough time for his teammates to come and assist Earth Spirit.
* The huge range of Stone Remnant and Rolling Boulder enables Earth Spirit to stop Tinker from teleporting to his fountain since Tinker tends to buy Blink Dagger most of the time to escape.
Omniknight
[wiki] rating: 1.0 (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.
Viper
[wiki] rating: 1.0 (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.
Legion Commander
[wiki] rating: 1.0 (winrate: 47% pickrate: 11%)Tinker
* 
Press the Attack can dispel Laser's blind while providing great attack speed and health regeneration.
* Once caught in a 
Duel, Tinker, who completely relies on his spells to be effective, has little chances of survival with his low health pool and armor.
Zeus
[wiki] rating: 1.0 (winrate: 46% pickrate: 8%)Tinker
* Due to Tinker's low health pool, Zeus can easily burst Tinker down, while also cancelling Rearm.
* Once Zeus gets Aghanim's Scepter, he will gain 
Nimbus, which allows him to scout out Tinker on the map, especially when he is pushing lanes while hiding in the trees.
Additional:
* Zeus can easily reveal Tinker's location in the trees with 
Thundergod's wrath.
* When Zeus has an Aghanim's Scepter, he can use his Nimbus, together with 
Lightning Bolt to interrupt Tinker's Boots of Travel channelling and cancel Tinker's Blink Dagger.
Pudge
[wiki] rating: 1.0 (winrate: 46% pickrate: 19%)Tinker
* He can 
Meat Hook a Tinker hiding in the trees and follow it up with 
Dismember and 
Rot for an easy solo kill, as Tinker doesn't tend to buy survivability items.
* His innate magic resistance and huge health pool from 
Flesh Heap makes it hard for Tinker to deal serious damage to Pudge.
Additional:
* Meat Hook can used to pull Tinker while he is hiding in the trees, and a follow up with Dismember and Rot leads to an easy solo kill, as Tinker doesn't buy many survivability items.
* Flesh Heap makes it hard for Tinker to deal serious damage.
Vengeful Spirit
[wiki] rating: 1.0 (winrate: 45% pickrate: 3%)Tinker
* 
Wave of Terror can reveal a Tinker attempting to hide in the trees and then 
Nether Swap and 
Magic Missile will both serve to interrupt/lock him down, should he attempt to town portal or reload.
Medusa
[wiki] rating: 1.0 (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.
Enigma
[wiki] rating: 0.6 (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
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.
Puck
[wiki] rating: 0.6 (winrate: 52% pickrate: 17%)Tinker
* Low health spellcasters: 
Lina, 
Witch Doctor, 
Tinker, 
Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
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.
Timbersaw
[wiki] rating: 0.6 (winrate: 48% pickrate: 8%)Tinker
* Timbersaw's ability to destroy trees can be a serious problem for some heroes that use them, as either a way of enhancing their spells like 
Treant Protector, or heroes that tend to hide inside of them like Tinker and 
Monkey King.
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.
Tinker
* All Tinker's damage is magic/pure and completely ignores Timbersaw's Reactive Armor.
* Timbersaw very rarely builds 
Black King Bar, making him very vulnerable if Tinker builds 
Scythe of Vyse.
Kunkka
[wiki] rating: 0.6 (winrate: 44% pickrate: 3%)Tinker
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and 
Nature's Prophet.
* In general, highly mobile heroes like 
Earth Spirit or 
Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Additional:
* 
X Marks the Spot can be used to prevent Tinker from escape with Blink Dagger or Boots of Travel, discourage him from snapping farm and snapping gank. However, in later game, it'll be much more difficult because Tinker can buy Black King Bar or 
Linken's Sphere to prevent Kunkka from placing X on him, or 
Eul's Scepter of Divinity to prevent the recall
Outworld Destroyer
[wiki] rating: 0.4 (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.
Tinker
* Tinker's Laser is useful against Outworld Devourer, as the blind prevents him from landing Arcane Orbs.
Spirit Breaker
[wiki] rating: 0.4 (winrate: 51% pickrate: 8%)Tinker
* Tinker relies on his high mobility from Boots of Travel and Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel Rearm and Boots of Travel.
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.
Tinker
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, 
Sniper, Tinker, 
Windranger.
Necrophos
[wiki] rating: 0.4 (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.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, 
Enchantress, 
Gyrocopter, 
Lion, 
Riki, 
Techies, 
Terrorblade, 
Necrophos, Invoker.
Shadow Fiend
[wiki] rating: -2.0 (winrate: 46% pickrate: 18%)Tinker
* During the laning stage Laser will reduce Shadow Fiend's last hits, preventing him from getting 
Necromastery souls.
* Shadow Fiend has low health and is vulnerable to Tinker's high magic burst.
Additional:
* The blind from Laser prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Scythe of Vyse can be used to prevent Shadow Fiend from casting Requiem of Souls.
* A combination of Tinker's abilities and his items (like the 
Dagon 5 and 
Ethereal Blade combo) can kill Shadow Fiend quickly.
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.
Faceless Void
[wiki] rating: -1.6 (winrate: 41% pickrate: 3%)Tinker
* If Tinker can stay outside of 
Chronosphere, Laser can cause Faceless Void to miss all his attacks.
* Faceless Void has low health and strongly relies on 
Time Walk's healing factor to remain alive. Getting caught by Tinker with Scythe of Vyse will almost always spell a quick end for Void.
* Rearm ignores 
Time Dilation completely.
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: -1.6 (winrate: 44% pickrate: 5%)Tinker
* Tinker with Rearm and Boots of Travel can teleport and defend towers whenever Nature's Prophet tries to push.
* Laser prevents Nature's Prophet from attacking. Additionally, even with 
Monkey King Bar, Nature's Prophet cannot hit towers and buildings.
* March of the Machines can easily kill an entire wave of Treants, giving Tinker lots of gold.
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: -1.6 (winrate: 45% pickrate: 16%)Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, 
Wraith King, 
Huskar.
Additional:
* The blind from Laser can render Phantom Assassin useless if she is not protected by Black King Bar.
* Tinker is a natural Scythe of Vyse carrier and can permanently disable Phantom Assassin, not giving her chance to activate Black King Bar if she has it.
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.
Mars
[wiki] rating: -1.6 (winrate: 48% pickrate: 16%)Axe
* Berserker's Call forces Mars to face in the direction choosen.
* Counter Helix is a much stronger lane trader than Spear of Mars.
Tinker
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, 
Enigma, Invoker, 
Pugna, 
Skywrath Mage, Tinker, 
Zeus, 
Oracle.
Riki
[wiki] rating: -1.6 (winrate: 48% pickrate: 5%)Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
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.
Bloodseeker
[wiki] rating: -1.6 (winrate: 51% pickrate: 4%)Tinker
* Laser can be very effective against 
Bloodrage as the damage will be amplified while the blind prevents Bloodseeker from landing hits.
* Tinker is a natural Boots of Travel carrier and Rearm guarantees him escape from Rupture.
Additional:
* Laser blinds Bloodseeker, preventing him from getting last hits and denies during the laning stage and preventing him from finishing off enemies.
* Tinker always buys Boots of Travel, helping him escape Bloodseeker's early ganks.
* Tinker's heavy magical damage will burst down Bloodseeker during the early to mid game, as he has little health.
Axe
* Heroes with high armor and durability can be exceptionally hard for Bloodseeker to bring down: 
Dragon Knight, Axe
Windranger
[wiki] rating: -1.6 (winrate: 51% pickrate: 16%)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.
Tinker
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, 
Viper, Skywrath Mage, Lion, Lina, 
Venomancer.
Huskar
[wiki] rating: -1.6 (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.
Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Terrorblade
[wiki] rating: -1.4 (winrate: 46% pickrate: 4%)Tinker
* Illusion heroes, such as 
Naga Siren, 
Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, 
Mjollnir or 
Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Tinker
* Tinker can single-handedly stop Terrorblade's early-push and quickly clear his illusions with Laser (especially with Aghanim's Scepter) and March of Machines.
* Tinker has perfect tools to reveal Terrorblade from his illusions as well as to burst him down if he is low-health before he will be able 
Sunder.
Additional:
* An Aghanim's Scepter upgraded Laser allows Tinker to blind Terrorblade and illusions.
* Tinker can also clear Terrorblade's illusions and stall his pushing attempts with March of the Machines .
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.
Drow Ranger
[wiki] rating: -1.4 (winrate: 47% pickrate: 4%)Axe
* Ranged heroes that can easily harass Axe: 
Drow Ranger, Sniper, Lion.
Tinker
* Laser applies a blind debuff, making Drow Ranger miss her high damage attacks.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.
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.
Chaos Knight
[wiki] rating: -1.4 (winrate: 52% pickrate: 3%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Tinker
* With Aghanim's Scepter, Tinker's Laser completely stops Chaos Knight's damage, forcing him to buy either a Black King Bar for his own survivability while leaving his illusions still vulnerable, or a Monkey King Bar leaving him still vulnerable to Tinker's nukes, though improving his damage.
* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.
Additional:
* Tinker's Aghanim's Scepter upgraded Laser can blind him and all of his Phantasm illusions.
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.
Monkey King
[wiki] rating: -1.2 (winrate: 50% pickrate: 16%)Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, 
Alchemist, 
Earthshaker, Razor, Tinker, Leshrac, Queen of Pain
Axe
* Heroes that can keep Monkey King stunned for a long time can pose a threat: Axe, 
Centaur Warrunner.
Magnus
[wiki] rating: -1.0 (winrate: 44% pickrate: 4%)Tinker
* Tinker can break Magnus's Blink Dagger using March of the Machines and Heat-Seeking Missile, therefore delaying any initiation or making Magnus use Skewer or 
Force Staff to initiate. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.
Lone Druid
[wiki] rating: -1.0 (winrate: 46% pickrate: 1%)Tinker
* Laser blinds Lone Druid, making his attacks miss. Furthermore, a Tinker with Aghanim's Scepter is sure to blind both Lone Druid and his bear, negating his ability to root or deal physical damage.
Morphling
[wiki] rating: -1.0 (winrate: 46% pickrate: 12%)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.
Oracle
[wiki] rating: -1.0 (winrate: 51% pickrate: 10%)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.
Weaver
[wiki] rating: -1.0 (winrate: 51% pickrate: 13%)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.
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.
Troll Warlord
[wiki] rating: -1.0 (winrate: 52% pickrate: 12%)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.
Dark Willow
[wiki] rating: -1.0 (winrate: 52% pickrate: 7%)Axe
* Berserker's Call forces Dark Willow to attack, cancelling Shadow Realm.
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.
Broodmother
[wiki] rating: -1.0 (winrate: 53% pickrate: 2%)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.
Visage
[wiki] rating: -1.0 (winrate: 54% pickrate: 1%)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.
Enchantress
[wiki] rating: -0.6 (winrate: 46% pickrate: 1%)Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Queen of Pain
[wiki] rating: -0.6 (winrate: 47% pickrate: 9%)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.
Grimstroke
[wiki] rating: -0.6 (winrate: 47% pickrate: 12%)Tinker
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Earthshaker
[wiki] rating: -0.6 (winrate: 49% pickrate: 12%)Tinker
* Tinker's March of the Machines will disable Blink Dagger over a large area.
Pangolier
[wiki] rating: -0.6 (winrate: 49% pickrate: 12%)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
Void Spirit
[wiki] rating: -0.6 (winrate: 50% pickrate: 13%)Axe
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like 
Ursa, 
Lifestealer, or Axe.
Tusk
[wiki] rating: -0.6 (winrate: 50% pickrate: 13%)Axe
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, 
Night Stalker, Centaur Warrunner, Wraith King and more.
Wraith King
[wiki] rating: -0.6 (winrate: 51% pickrate: 17%)Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Io
[wiki] rating: -0.6 (winrate: 51% pickrate: 7%)Axe
* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer
Shadow Shaman
[wiki] rating: -0.6 (winrate: 52% pickrate: 16%)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.
Clinkz
[wiki] rating: -0.6 (winrate: 53% pickrate: 4%)Tinker
* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Razor
[wiki] rating: -0.6 (winrate: 54% pickrate: 6%)Tinker
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
Lycan
[wiki] rating: -0.6 (winrate: 54% pickrate: 3%)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:
* 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.
Anti-Mage
[wiki] rating: -0.4 (winrate: 49% pickrate: 13%)Tinker
* Anti-Mage's high mobility from Blink and tendency to build Battle Fury makes him strong against split-pushing heroes: Nature's Prophet, Tinker, and Arc Warden.
Additional:
* Tinker is fragile and vulnerable against carries like Anti-Mage.
* 
Mana Break burns away his mana pool and deals bonus physical damage.
* Tinker's massive mana pool makes 
Mana Void deal large amount of damage, and can be used to cancel a Boots of Travel teleport even through spell immunity.
* 
Blink gives Anti-Mage many options, like disjointing Heat Seeking Missiles or leaving March of Machines' area of effect. He can use Blink to wait out of sight for a split pushing Tinker or chase a blinking Tinker into trees.
* Tinker doesn't want any of his spells reflected back at him through 
Counterspell.
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.
Sniper
[wiki] rating: -0.4 (winrate: 49% pickrate: 6%)Axe
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Axe
* Axe can easily close the distance to Sniper with either Blink Dagger or 
Shadow Blade.
* With Berserker's Call in combination with Counter Helix and Battle Hunger, Axe can make short work of Sniper, finishing him off easily with Culling Blade due to his low HP & high attack speed in the late game.
Winter Wyvern
[wiki] rating: -0.4 (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
Tinker
* All of his damage is magical and pure, which makes Cold Embrace a good setup for his nukes.
* Winter's Curse is very hard to cast on Tinker because he usually stays in the back-lines in team-fights. In turn, Tinker has mediocre attack damage and will contribute very little when he is cursed to attack an ally. He can also save his ally under Winter's Curse effect with Ethereal Blade.
Phantom Lancer
[wiki] rating: -0.4 (winrate: 51% pickrate: 10%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Axe
* Berserker's Call helps locks down Phantom Lancer in a group of illusions.
* Counter Helix combined with Blade Mail clears Phantom Lancer's illusions quickly.
* Phantom Lancer's low health in the early game makes him a frequent target for Culling Blade.
Additional:
* Berserker's Call catches Phantom Lancer when he is hidden among his illusions.
* Counter Helix quickly destroys Phantom Lancer's illusion army. The more illusions there are, the more often Counter Helix is triggered.
* Phantom Lancer's low early game health makes him an easy target for Culling Blade.
Naga Siren
[wiki] rating: -0.4 (winrate: 54% pickrate: 2%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Axe
* Axe will destroy her illusions by proccing Counter Helix more often due to him being hit by more attacks.
Techies
[wiki] rating: -0.2 (winrate: 48% pickrate: 8%)Tinker
* A common playstyle among Tinkers is to teleport to a lane creep using Boots of Travel and immediately blink into the trees to cast March of the Machines. If Techies can predict where said Tinker would blink after teleporting, he could place strategic Proximity Mines or even Remote Mines in those places. Stasis Traps also prevent Tinker from blinking or teleporting away.
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.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Meepo
[wiki] rating: 0.0 (winrate: 45% pickrate: 1%)Tinker
* Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
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.
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.
Dazzle
[wiki] rating: 0.0 (winrate: 48% pickrate: 5%)Tinker
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
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.
Slark
[wiki] rating: 0.0 (winrate: 48% pickrate: 13%)Tinker
* 
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.
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
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Lion
[wiki] rating: 0.0 (winrate: 50% pickrate: 17%)Axe
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Invoker
[wiki] rating: 0.0 (winrate: 50% pickrate: 16%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider
Additional:
* Tinker is relatively helpless against Invoker, as his Rearm and Boots of Travel can be easily interrupted by Invoker's long range disables, even if he blinks away.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Gyrocopter
[wiki] rating: 0.0 (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.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Luna
[wiki] rating: 0.0 (winrate: 51% pickrate: 7%)Tinker
* Luna can easily prevent Tinker from escaping with Boots of Travel or Rearm with 
Lucent Beam.
* Luna can also quickly tear Tinker to shreds with 
Eclipse as soon as he jumps in with Blink Dagger.
Tinker
* Tinker's March of the Machines and Laser both destroy Luna's small health pool and make it hard for Luna to initiate with Eclipse (and making it hard to land glaives in Laser's case).
* Since Tinker typically buys Blink Dagger, Luna has a hard time catching him despite her high movement speed.
* Tinker can easily disable and nuke Luna down with 
Dagon or Scythe of Vyse before she can use Lucent Beam or Eclipse.
Arc Warden
[wiki] rating: 0.0 (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
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.
Tinker
*
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
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.
*
