Tinker
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest a mobile ally (teams usually pick one against Tinker), which may ensure that Tinker will die if he is caught.
Additional:
* 
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.
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. Clockwerk can also 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).
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.
Tinker
* Even though Luna has a hard time laning against Tinker because of 
Heat-Seeking Missile and 
Laser, she can win against him in late game once she buys 
Black King Bar, as none of Tinker's spells can bypass spell immunity.
* 
Lucent Beam and 0.25 
Eclipse Lucent Mini-stun talent for Eclipse can be used to cancel Rearm and prevent Tinker's escape attempts with 
Boots of Travel. Luna can also use Lucent Beam and Eclipse if she is blinded with Laser.
* An ill-timed and ill-positioned 
Blink Dagger will make Tinker a very easy target for Luna's Eclipse that can quickly tear him to shreds. This can get even better if Luna buys 
Aghanim's Scepter and combines it with 0.25 Eclipse Lucent Mini-stun talent for Eclipse.
* However, Luna needs to approach Tinker carefully, as Tinker is a natural 
Scythe of Vyse wielder, and if he gets a jump on Luna first, he will be able to use it to disable and burst down Luna before she can use Black King Bar, Lucent Beam or Eclipse.

Tinker
* 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.
Additional:
* Nyx Assassin's whole skillset is good against Tinker:
* 
Impale prevents Tinker from blinding Nyx Assassin or fighting back, while giving Nyx' allies time to catch up to Tinker's position.
* 
Mind Flare 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.
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.
Tinker
* 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 
Keen Conveyance channelling and cancel Tinker's Blink Dagger.
Additional:
* 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.
Tinker
* Tinker relies on his high mobility from Keen Conveyance 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 Keen Conveyance.
Tinker
* Silencer can stop Rearm, preventing Tinker from spamming his abilities/items or escaping.
* Tinker heavily relies on his mana pool and has mana issues throughout the entire game and Silencer's intelligence steal does not help with that.
Additional:
* 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.
* Silencer's intelligence steal permanently weakens Tinker since he's a hero who requires lots of mana to be effective.
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.
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.
* 
Dispersion can reflect and reduce his burst damage.
Tinker
* Meat Hook can be used to pull Tinker to Pudge while he is hiding in the trees, and a follow up with Dismember and Rot can lead to a valuable kill, as Tinker doesn't buy many survivability items.
* Flesh Heap makes it hard for Tinker to deal serious damage.
Additional:
* Pudge 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.
* Many stacks of 
Flesh Heap combined with items that give Pudge high strength and health will make it hard for Tinker to deal serious damage to Pudge.
Tinker
* 
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
Tinker
* Skywrath Mage stands perfectly on the center line against Tinker, thanks to his nuke and silence. Also, thanks to his abilities, he can quickly kill a victim, and Tinker is one of the most subtle heroes in the game

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.
Tinker
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Tinker
* Tinker is heavily dependent on his abilities and 
Doom prevents him from using any of them.
* This becomes even worse if Doom chooses the level 25 talent {ValueColor:1|Doom applies Mute|25tal} {Symbol:Talent}, which will prevent Tinker from using items such as Blink Dagger.
Additional:
* 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.
Tinker
* 
Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
Tinker
* Heroes that can gain vision over trees to catch Tinker: 
Invoker, 
Shadow Demon, 
Batrider.
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 Keen Conveyance, 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.
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.
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 Keen Conveyance teleport.
* 
Blink gives Anti-Mage many options, like disjointing Heat Seeking Missiles. 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.
Tinker
* Illusion heroes, such as 
Naga Siren, 
Phantom Lancer, 
Chaos Knight, 
Terrorblade will become strong against Tinker in the late game. 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
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider.
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.
Tinker
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, 
Riki, Tinker
Tinker
* 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.
Tinker
* Tinker's Laser has very little effect on Jakiro.
* Tinker has to sit still for a short period of time due to Rearm, not only making it easy to catch him with Ice Path, but also by stunning him while he is Rearming, Jakiro generally spell Tinker's doom.
* With s high area-of-effect and strong damage-over-time capabilties, Jakiro can quickly burn through his 
Defense Matrix, and at the same time lock down his Blink Dagger. Both of which he relies heavily to survive on.
Tinker
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, 
Sniper, Tinker, 
Windranger.
Tinker
* All of Tinker's damage is magic/pure and completely ignores Enchantress's 
Untouchable. And Tinker's nukes can quickly decimate her small HP pool, sometimes even preventing Enchantress from even responding.
* As Enchantress relies solely on her primary attacks to deal damage, and rarely builds something to dispel it, Laser's Blind is particularly effective.
* However, Enchantress will probably build a Linken's Sphere against Tinker's Laser, so getting an additional disable is highly recommended.
Tinker
* Tinker has great map presence because of Keen Conveyance and Rearm, which means he can always 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 during the effect.
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.
Tinker
* Tinker is one of the few heroes who is able to defeat a Sniper on the center line thanks to his long-ranged abilities.
* Laser allow Tinker to deal damage to Sniper and blind him, causing him to miss attacks more often.
* Heat-Seeking Missile can deal heavy damage to Sniper on lane.
* Defense Matrix allow Tinker to save himself or allies from 
Assassinate.
* 
Warp Flare from 
Aghanim's Shard allows Tinker to teleport Sniper away from himself, while also reducing both his attack range and cast range. If Sniper is teleported near Tinker's allies with Warp Flare, he will be bursted down in no time.
Additional:
* Tinker is one of the few characters in Dota 2 who is able to defeat a Sniper on the center line – Tinker. On the center line, he gains an advantage over his opponent, and later acquires additional control. It is these abilities that the enemy should have in the game against the Sniper.
Tinker
* Tinker can use Laser to save an ally or himself from Phantom Assassin's initiate 
Phantom Strike due to the blind, forcing her to use a Black King Bar to effectively initiate, Tinker can also use Warp Flare one he buys Aghanim's Shard to reverse Phantom Strike's blinking with Phantom Strike.
* Tinker almost never uses his physical attack, relying on his spell-spamming to deal damage which ignores 
Blur's Evasion
* Defense Matrix prevents 
Coup de Grace from triggering.
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. His {Ability ID:Defense Matrix|Tinker} will decrease the duration of Reverse Polarity and can also be cast on all of his teammates with {Ability ID:Rearm|Tinker}. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.
Tinker
* Viper is kind of a mixed package. Tinker is very good against him. but stands a better chance against him than most heroes.
* Viper has a high innate magic resistance, but relies on his primary attacks to really deal damage. making Laser an effective way to save allies from him, and deal damage. Keep in mind that his 
Corrosive Skin will prevent Tinker from blinking.
* Viper's 
Viper Strike and 
Poison Attack will also have a hard time damaging allies through Tinker's constant casting of Defense Matrix.
* Viper has no solutions to cancel Rearm nor any of Tinker's escape attempts with Boots of Travel
* However, if Viper gets a jump on Tinker first. Tinker will unlikely survive versus Viper.
Tinker
* Laser can be cast on a initiating Ursa, normally causing him to waste multiple 
Overpower attacks, forcing him to either Black King's Bar, or 
Enrage to protect himself.
* Ursa will probably carry a Linken's Sphere to counter Tinker's Laser. Popping it with Scythe of Vyse is actually preferable, due to Laser's high Pure damage.
* While Ursa is a common Blink Dagger carrier, but he otherwise has no way to close the gap, Baiting him into using his Blink, then blinking away, allows Tinker to easily kite Ursa.
* Enrage is generally how Ursa disengages, Due to Tinker's high maneuverability, he can follow him until it runs out. then burst him down with high magic damage.
Tinker
* 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.
Additional:
* Laser can be very effective against 
Bloodrage as the damage will be amplified while the blind prevents Bloodseeker from landing hits.
* Keen Conveyance guarantees him escape from Rupture.
Tinker
* Laser along with Heat-Seeking Missile allows Tinker to quickly burst down Drow Ranger due to her low health.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.
Tinker
* 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.
Additional:
* 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.
Tinker
* Laser blinds Lone Druid, making his attacks miss.
Tinker
* All of Tinker's 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 and Defense Matrix.
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.
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.
Tinker
* Heroes with either magical, physical or pure damage burst: 
Bane, 
Ember Spirit, Leshrac, Lina, 
Luna, 
Nyx Assassin, 
Phantom Assassin, Skywrath Mage, Tinker, 
Ursa, 
Void Spirit.
Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, 
Alchemist, 
Earthshaker, 
Razor, Tinker, Leshrac, 
Queen of Pain
Tinker
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker, 
Jakiro, Lina, Luna, 
Pugna or 
Ogre Magi, 
Enigma, Batrider, Techies, 
Broodmother, 
Dawnbreaker, 
Shadow Shaman, Bane, Tinker, Venomancer, Arc Warden.
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.
Tinker
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, 
Oracle.
Tinker
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
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
Tinker
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
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.
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.
Tinker
* Lion has an incredibly fragile health pool, making him weak against nukers like Tinker or Oracle.
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.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, 
Wraith King, 
Huskar.
Tinker
* Tinker's Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
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.
Tinker
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, Ursa, Void Spirit.
Tinker
* Heroes with magical or pure damage output will not have any problems against Atrophy Aura at all: Luna, Lina, Jakiro, Pugna, Bane, 
Snapfire, 
Muerta, Nyx Assassin, Enigma, Tinker, Witch Doctor, Zeus, Crystal Maiden.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game. 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
* Laser prevents 
Juxtapose from triggering, as it only triggers on successful attacks
* Laser does high splash, and upgrading it with Aghanim's Scepter makes it deal twice as much damage due to the bounce. Combined with Rearm, Tinker can rapidly deplete Phantom Lancer's illusion army
* However, if Phantom Lancer ambushes Tinker, Tinker will not survive versus Phantom Lancer.
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.
Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game. 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.
Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game. 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
* An Aghanim's Scepter upgraded Laser allows Tinker to blind Terrorblade and his illusions.
* Tinker deals incredible amounts of pure and magical damage with Laser and Heat-Seeking Missile combined with Rearm, which will ignore Terrorblade's armor and be devastating to his low health pool.
* Tinker is a hero who very often goes for Blink Dagger, and because Terrorblade has no disable to lock down Tinker, he will be unable to catch up with him nor to prevent him from escaping with Boots of Travel.
* Even if Terrorblade manages to catch up to Tinker, Tinker can simply teleport Terroblade away from him with Warp Flare provided by Aghanim's Shard, which can also weaken Terrorblade's attack range and cast range.
Additional:
* Tinker can single-handedly stop Terrorblade's early-push and quickly clear his illusions with Laser (especially with Aghanim's Scepter).
* 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.
Tinker
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, Tinker, and 
Templar Assassin.
Tinker
* Heroes who can do scaling health damage to Primal Beast are very threatening for the hero. Such as: Phoenix, Tinker etc.
Tinker
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
Dark Ascension.
Void's mini-stun will stop Rearm and 
Keen Conveyance
Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
Additional:
* Night Stalker can easily find Tinker in the trees during
*
*
