Spirit Breaker
[wiki] rating: 2.0 (winrate: 50% pickrate: 8%)Zeus
[wiki] rating: 2.0 (winrate: 49% pickrate: 11%)Bounty Hunter
* Bounty Hunter has a very low health pool, allowing Zeus to burst him down quickly.
* Zeus can cast Lightning Bolt to gain True Sight in any area he suspects Bounty Hunter may be invisible or any area he thinks Bounty Hunter may have warded.
* If Bounty Hunter tries to escape a gank by using 
Shadow Walk, Zeus can gain vision of him with both Lightning Bolt and Thundergod's Wrath.
Additional:
* 
Lightning Bolt makes roaming behind enemy lines more and more difficult as Zeus becomes powerful enough to spam it. Also, Zeus' Ultimate 
Thundergod's Wrath reveals Bounty Hunter regardless of his position.
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.
Spectre
[wiki] rating: 2.0 (winrate: 46% pickrate: 6%)Bounty Hunter
* Spectre can instantly reveal Bounty Hunter's position on the activation of her ultimate 
Haunt. She can also semi-reveal( visible but not target-able) Bounty Hunter by hitting him with 
Spectral Dagger.
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.
Night Stalker
[wiki] rating: 1.6 (winrate: 53% pickrate: 5%)Bounty Hunter
* 
Night Stalker's 
Crippling Fear at night prevents Shadow Walk for an extended period of time and his 
Void will make Phase Boots useless. If Night Stalker has True Sight, he can shutdown Bounty Hunter's sneak kill.
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.
Storm Spirit
[wiki] rating: 1.6 (winrate: 50% pickrate: 10%)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.
Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like 
Abaddon and 
Wraith King to heroes with quick escape mechanisms like 
Anti-Mage and 
Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Phantom Lancer
[wiki] rating: 1.6 (winrate: 49% pickrate: 7%)Bounty Hunter
* Doppelganger dispels 
Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.
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.
Legion Commander
[wiki] rating: 1.6 (winrate: 48% pickrate: 13%)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.
Bounty Hunter
* 
Legion Commander with Press the Attack
* Heroes that can remove the Track debuff with their skills:
* Abaddon with 
Aphotic Shield and 
Borrowed Time
* 
Huskar with 
Life Break
* 
Juggernaut with 
Blade Fury
* Legion Commander with Press the Attack
* 
Lifestealer with 
Rage and 
Infest
* Naga Siren with 
Mirror Image
* 
Omniknight with 
Heavenly Grace
* 
Oracle with 
Fortune's End and 
False Promise
* Phantom Lancer with 
Doppelganger
* 
Slark with 
Dark Pact
* 
Ursa with 
Enrage
* 
Weaver with 
Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Slark
[wiki] rating: 1.6 (winrate: 48% pickrate: 13%)Bounty Hunter
* Slark with Dark Pact
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
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.
Lifestealer
[wiki] rating: 1.6 (winrate: 46% 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.
Bounty Hunter
* Lifestealer with Rage and Infest
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Naga Siren
[wiki] rating: 1.2 (winrate: 50% 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.
Bounty Hunter
* Naga Siren with Mirror Image
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Additional:
* Bounty Hunter is a single target dealer, so he will not fare well against Naga Siren. He might as well try to Track her, but her Mirror Image will dispel the effect. Also, Ensnare reveals invisible units while they're rooted, putting Bounty Hunter in a tricky situation.
Anti-Mage
[wiki] rating: 1.2 (winrate: 48% pickrate: 14%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
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.
Beastmaster
[wiki] rating: 1.0 (winrate: 55% pickrate: 4%)Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Clockwerk
[wiki] rating: 1.0 (winrate: 51% 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).
Venomancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 5%)Bounty Hunter
* Venomancer's magical damage-over-time poisons greatly reduce Bounty Hunter's mobility.
* 
Venomous Gale, 
Plague Wards and 
Poison Nova with True Sight items can allow Venomancer and his teammates to gank Bounty Hunter while he is roaming alone.
Death Prophet
[wiki] rating: 1.0 (winrate: 50% pickrate: 2%)Bounty Hunter
* Death Prophet's 
Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with 
Crypt Swarm and 
Spirit Siphon.
Earth Spirit
[wiki] rating: 1.0 (winrate: 50% pickrate: 9%)Tinker
* Tinker is an easy target for Earth Spirit to initiate on. He likes to split push lanes once he acquieres 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.
Luna
[wiki] rating: 1.0 (winrate: 49% pickrate: 4%)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.
Bounty Hunter
* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from Eclipse, smart Luna will always buy 
Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.
Additional:
* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from Eclipse, smart Luna will always buy Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.
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.
Silencer
[wiki] rating: 1.0 (winrate: 49% pickrate: 8%)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.
Dazzle
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Tinker
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
Slardar
[wiki] rating: 1.0 (winrate: 48% pickrate: 8%)Bounty Hunter
* 
Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* 
Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
Techies
[wiki] rating: 1.0 (winrate: 48% pickrate: 7%)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.
Bounty Hunter
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, 
Riki, Weaver, 
Earthshaker, 
Nyx Assassin, etc. that are constantly moving around the map.
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.
Viper
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Bounty Hunter
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.
* 
Nethertoxin can break Jinada, and the silence from level 25 prevents Bounty Hunter from using all of his spells.
Vengeful Spirit
[wiki] rating: 1.0 (winrate: 47% pickrate: 7%)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.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 17%)Bounty Hunter
* Rubick is a potential counter to Bounty Hunter as he can steal his Track and use it against his invisibility, and also provide his team with more gold if the tracked hero is killed.
Doom
[wiki] rating: 1.0 (winrate: 44% pickrate: 3%)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.
Underlord
[wiki] rating: 0.6 (winrate: 54% pickrate: 8%)Bounty Hunter
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: 
Sven, 
Tiny, Wraith King, 
Dragon Knight, 
Meepo, 
Doom, Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Juggernaut
[wiki] rating: 0.6 (winrate: 53% pickrate: 19%)Bounty Hunter

Puck
[wiki] rating: 0.6 (winrate: 52% pickrate: 15%)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.
Chaos Knight
[wiki] rating: 0.6 (winrate: 51% pickrate: 4%)Bounty Hunter
* Phantasm dispels Track, and the illusions make it difficult to Track the real Chaos Knight.
* Bounty Hunter is fragile and can easily be killed by Chaos Knight and Phantasm's illusions.
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.
Oracle
[wiki] rating: 0.6 (winrate: 50% pickrate: 9%)Bounty Hunter

[wiki] rating: 0.6 (winrate: 48% pickrate: 5%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, 
Shadow Demon, 
Batrider
Meepo
[wiki] rating: 0.6 (winrate: 47% pickrate: 1%)Tinker

Shadow Demon
[wiki] rating: 0.6 (winrate: 47% pickrate: 3%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider
Bristleback
[wiki] rating: 0.6 (winrate: 45% pickrate: 8%)Bounty Hunter
* 
Bristleback's 
Viscous Nasal Goo can catch and slow Bounty Hunter. 
Warpath and 
Quill Spray can defeat him quickly due to his small HP pool when compared to Bristleback's.
Kunkka
[wiki] rating: 0.6 (winrate: 45% pickrate: 4%)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
Pugna
[wiki] rating: 0.4 (winrate: 51% pickrate: 4%)Tinker
* 
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, 
Pugna, 
Skywrath Mage, 
Io, Witch Doctor, etc.
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.
Bounty Hunter
* Bounty Hunter can absolutely destroy a Shadow Fiend's game by ganking his midlane with Shadow Walk, Jinada and Shuriken Toss.
* If his lane goes bad, a Shadow Fiend usually goes to the jungle. Follow him with Shadow Walk and take half of his experience.
* Due to its ministun, Shuriken Toss is a good way to interrupt Shadow Fiend's long cast animation on 
Requiem of Souls.
Additional:
* 
Shuriken Toss can be used to cancel Requiem of Souls.
* Shadow Walk and 
Jinada allow Bounty Hunter to gank Shadow Fiend early on
* Track prevents Shadow Fiend from escaping with Shadow Blade.
Nature's Prophet
[wiki] rating: -1.6 (winrate: 46% 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.
Bounty Hunter
* Heroes with detection: Bounty Hunter, 
Disruptor, 
Razor, 
Slardar, 
Spectre, 
Spirit Breaker
Riki
[wiki] rating: -1.6 (winrate: 53% pickrate: 12%)Bounty Hunter
* Track gives Riki a hard time, as it prevents much of his ganking capabilities.
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.
Clinkz
[wiki] rating: -1.2 (winrate: 52% pickrate: 5%)Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:
Clinkz, Riki, 
Treant Protector, etc.
Additional:
* Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
* Jinada with physical damage items can quickly kill Clinkz due to his low health.
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.
Monkey King
[wiki] rating: -1.2 (winrate: 53% pickrate: 18%)Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, Alchemist, Earthshaker, Razor, Tinker, 
Leshrac, 
Queen of Pain
Bounty Hunter
* 
Monkey King is also hindered by Track since he relies on trees to hide him from vision.
Additional:
* Track grants vision of Monkey King, even when he's in the trees.
Magnus
[wiki] rating: -1.0 (winrate: 45% pickrate: 6%)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.
Sniper
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Bounty Hunter
* 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.
Drow Ranger
[wiki] rating: -1.0 (winrate: 50% pickrate: 8%)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.
Crystal Maiden
[wiki] rating: -1.0 (winrate: 50% pickrate: 14%)Bounty Hunter
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
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.
Bounty Hunter
* Shuriken Toss's stun is useful for cancelling Freezing Field from a distance.
* Track can be used for revealing Crystal Maiden when she uses 
Glimmer Cape.
* Jinada does burst physical damage (which is even bigger if dealt under Track's crits), which is effective due to Crystal Maiden's low HP and armor.
* Bounty Hunter likes to stay hidden from the fight and is less likely to get caught by Crystal Maiden's spells.
Void Spirit
[wiki] rating: -1.0 (winrate: 50% pickrate: 10%)Bounty Hunter
* One hit with Jinada should be sufficient in removing Void Spirit's shield most of the time.
* Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Lone Druid
[wiki] rating: -1.0 (winrate: 51% pickrate: 2%)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.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 51% pickrate: 5%)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 Assassin
[wiki] rating: -0.6 (winrate: 46% 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.
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.
Witch Doctor
[wiki] rating: -0.6 (winrate: 47% pickrate: 13%)Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, 
Sniper, Ursa, Witch Doctor, etc.
Grimstroke
[wiki] rating: -0.6 (winrate: 47% pickrate: 10%)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
Io
[wiki] rating: -0.6 (winrate: 47% pickrate: 4%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Chen
[wiki] rating: -0.6 (winrate: 48% pickrate: 0%)Bounty Hunter
* Invisibility heroes can sneak past Chen's creeps and pick him off: Nyx Assassin, Weaver, Bounty Hunter Riki.
Gyrocopter
[wiki] rating: -0.6 (winrate: 48% pickrate: 3%)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.
Earthshaker
[wiki] rating: -0.6 (winrate: 48% pickrate: 10%)Tinker
* Tinker's March of the Machines will disable Blink Dagger over a large area.
Necrophos
[wiki] rating: -0.6 (winrate: 49% pickrate: 4%)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: -0.6 (winrate: 50% pickrate: 17%)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.
Bounty Hunter
* Bounty Hunter and Slardar both have ultimates (Corrosive Haze and Track) that reveal Invoker through Ghost Walk.
Skywrath Mage
[wiki] rating: -0.6 (winrate: 50% pickrate: 6%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Windranger
[wiki] rating: -0.6 (winrate: 50% pickrate: 16%)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.
Jakiro
[wiki] rating: -0.6 (winrate: 50% pickrate: 11%)Tinker
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, Sniper, Tinker, 
Windranger.
Templar Assassin
[wiki] rating: -0.6 (winrate: 50% pickrate: 5%)Bounty Hunter
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, 
Tusk, Bounty Hunter, Riki, 
Warlock.
Outworld Destroyer
[wiki] rating: -0.6 (winrate: 50% pickrate: 6%)Tinker
* Tinker's Laser is useful against Outworld Devourer, as the blind prevents him from landing Arcane Orbs.
Mirana
[wiki] rating: -0.6 (winrate: 50% pickrate: 16%)Bounty Hunter
* Heroes with spells that negate invisibility such as Bounty Hunter, Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.
Treant Protector
[wiki] rating: -0.6 (winrate: 52% pickrate: 6%)Bounty Hunter
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:Clinkz, Riki, Treant Protector, etc.
Shadow Shaman
[wiki] rating: -0.6 (winrate: 52% pickrate: 15%)Bounty Hunter
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill you, Nyx being particularly deadly. Watch Slark carefully, as he can break either (but not both unless you are making a mistake) of your disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn you from prey to predator.
Ancient Apparition
[wiki] rating: -0.6 (winrate: 52% pickrate: 9%)Bounty Hunter
* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, Queen of Pain, Phantom Assassin, Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.
Razor
[wiki] rating: -0.6 (winrate: 54% pickrate: 2%)Tinker
* Heroes who rely on abilities to deal damage (e.g. 
Timbersaw, Tinker) can fight a Razor even after Static Link.
Faceless Void
[wiki] rating: -0.4 (winrate: 43% pickrate: 7%)Bounty Hunter
* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, 
Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
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.
Terrorblade
[wiki] rating: -0.4 (winrate: 46% pickrate: 5%)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 .
Timbersaw
[wiki] rating: -0.4 (winrate: 50% pickrate: 7%)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.
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.
Mars
[wiki] rating: 0.0 (winrate: 47% pickrate: 16%)Bounty Hunter
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Tinker
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, 
Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Pudge
[wiki] rating: 0.0 (winrate: 47% pickrate: 21%)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.
Bounty Hunter
* Bounty Hunter can easily keep vision on Pudge with Track, making it difficult for Pudge to hook Bounty Hunter or his team mates.
* It's difficult for Pudge to keep up with Bounty Hunter to apply Rot on him due to Shadow Walk.
* Shuriken Toss cancels out Dismember from a good range if Bounty Hunter is not the target.
Additional:
* Track can easily keep vision on Pudge, making it impossible to catch up with his Meat Hook for Bounty Hunter's teammates or him.
* It's very difficult for Pudge to use Rot on and hook Bounty Hunter due to Shadow Walk.
* Shuriken Toss cancels out Dismember from a good range.
Lion
[wiki] rating: 0.0 (winrate: 49% pickrate: 16%)Bounty Hunter
* Finger of Death can instantly shred many targets especially fragile Heroes like Keeper of the Light, 
Ancient Apparition, or Bounty Hunter.
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.
Ursa
[wiki] rating: 0.0 (winrate: 49% pickrate: 13%)Bounty Hunter
* Ursa with Enrage
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace

* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break

* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Bounty Hunter
* Bounty Hunter has a cheap way to break Linken's Sphere and keep track of Weaver while he is using Shukuchi, though both can be dispelled with Time Lapse.
Bloodseeker
[wiki] rating: 0.0 (winrate: 50% pickrate: 2%)Bounty Hunter
* 
Rupture can turn Bounty Hunter's mobility against him, and prevents him from escaping with Shadow Walk due to the potentially heavy damage.
* 
Thirst can prevent Bounty Hunter from escaping with Shadow Walk should Bounty Hunter's health become low enough, as it provides True Sight.
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.
Wraith King
[wiki] rating: 0.0 (winrate: 53% pickrate: 20%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Nyx Assassin
[wiki] rating: 0.0 (winrate: 54% pickrate: 13%)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.
Bounty Hunter
* Nyx Assassin wants to start ganking as soon as he gets his Vendetta. Keeping him Tracked prevents him from ganking, and thus from doing his job in the game.
* Nyx Assassin has a lot of armor and health regen, making the nuke damage from Shuriken Toss very good against him.
Additional:
* Track hinders Nyx Assassin's ganking attempts with Vendetta, making him an easy kill for gold as well.
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.
Rearm and 
Boots of Travel.
* Spirit Breaker can easily cancel
Bounty Hunter
* Spirit Breaker's
Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.
