Shadow Shaman
* 
Nyx Assassin, 
Bounty Hunter and 
Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with 
Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Tinker
* 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.
Additional:
* 
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.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as 
Silencer, 
Drow Ranger and 
Death Prophet.
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.
* Silencer's intelligence steal permanently weakens Tinker since he's a hero who requires lots of mana to be effective.
Additional:
* 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.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
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.
Shadow Shaman
* Heroes that have a channeled ability that can be interrupted by Meat Hook: 
Shadow Shaman, 
Witch Doctor, 
Enigma, 
Bane.
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.
Shadow Shaman
* Luna's high magical damage burst from 
Lucent Beam and 
Eclipse can take advantage of Shadow Shaman's low health and strength gain.
* Without 
Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Shadow Shaman while he is channeling 
Shackles.
* 
Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetitively stun Shadow Shaman, and can even discourage him from even trying to use Shackles.
* Luna is a natural Black King Bar wielder, and almost none of Shadow Shaman's spells can bypass spell immunity, except for 
Mass Serpent Ward.
* Bear in mind, however, that if Shadow Shaman gets a jump on Luna first, he will be able to use 
Hex to disable Luna and burst her down before she can use Black King Bar, Lucent Beam or Eclipse. In addition, 
Moon Glaives cannot bounce on Mass Serpent Wards at all.

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.
Additional:

Shadow Shaman
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: 
Sven + Shadow Shaman.
Shadow Shaman
* Due to their high attack speed, 
Summon Familiars will destroy Mass Serpent Wards quickly, granting Visage a massive amount of gold.
* Visage can use 
Stone Form of the Familiars to cancel Shackles. 
Aghanim's Shard upgraded Stone Form also allows Visage to use Stone Form himself to cancel Shackles while restoring his health.
* 
Grave Chill can make Shadow Shaman's bad movement speed and attack speed even worse.
* Visage is also a natural 
Bloodthorn wielder, which allows him to silence Shadow Shaman and make him more vulnerable to damage.
Additional:
* Due to their high attack speed, Visage's Summon Familiars will destroy Mass Serpent Ward quickly, granting Visage massive amount of gold.
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 
Keen Conveyance channelling and cancel Tinker's Blink Dagger.
Shadow Shaman
* Heroes with channeling spells are very easy targets for Jakiro's abilities: 
Crystal Maiden, 
Dawnbreaker, Enigma, 
Pudge, 
Shadow Fiend, Shadow Shaman, 
Warlock.
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
* Night Stalker can easily find Tinker in the trees during 
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 is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
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 a mobile ally (teams usually pick one against Tinker), which may ensure that Tinker will die if he is caught.
Tinker
* 
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
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
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
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
Additional:
* 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
* 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.
Shadow Shaman
* Mirana can disturb Shadow Shaman's channeling even if he is under the effect of invisibility thanks to 
Sacred Arrow.
* Mirana armed with an Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with 
Ethereal Blade the bullying towards Shadow Shaman can continue for the whole match.
Tinker
* 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).
Additional:
* 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.
Shadow Shaman
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Shadow Shaman
* 
Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with 
Adaptive Strike (Strength).
* With Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.
Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Shadow Shaman
* All abilities from Shadow Shaman can very vulnearble steal from 
Spell Steal.
* Rubick can interrupt Shackles by casting 
Telekinesis.
Additional:
* 
Ether Shock is a great farming ability as a handy short-cooldown nuke.
* Hex and Shackles gives Rubick extra lockdown potential in ganks and teamfights.
* Mass Serpent Ward, should Rubick steal, serves as a powerful source for teamfighting, pushing, and acquring Roshan.
* 
Arcane Supremacy allows Rubick to cast Hex and Shackles at a further distance, which keeps Rubick at a safer position compared to Shadow Shaman.
* Rubick can interrupt Shackles by casting Telekinesis.
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.
Shadow Shaman
* 
Arc Warden with his Magnetic Field will protect allies from Mass Serpent Ward.
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.
Shadow Shaman
* 
Omniknight can dispel Hex or Shackles with 
Heavenly Grace. He can also heal teammates who you disabled. The same goes for 
Abaddon's 
Aphotic Shield.
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.
Shadow Shaman
* As a caster, 
Anti-Mage's 
Mana Break and 
Mana Void are highly effective against him.
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.
Shadow Shaman
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: 
Lion, Silencer, Shadow Shaman, 
Grimstroke, Witch Doctor, 
Riki, 
Faceless Void, 
Skywrath Mage, 
Puck.
Shadow Shaman
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, 
Visage, 
Dazzle, 
Rubick, 
Lich.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Shadow Shaman
* Heroes that are squishy by nature are an easy target for Spirit Breaker: Sniper, Drow Ranger, Shadow Shaman
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.
Shadow Shaman
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
Shadow Shaman
* Omniknight can dispel Hex or Shackles with Heavenly Grace. He can also heal teammates who you disabled. The same goes for Abaddon's Aphotic Shield.
Shadow Shaman
* Pudge, 
Legion Commander and 
Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use 
Press the Attack on an ally who is hexed as well.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Tinker
* Heroes that can gain vision over trees to catch Tinker: 
Invoker, 
Shadow Demon, 
Batrider.
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
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider.
Shadow Shaman
* 
Reincarnation allows Wraith King to survive Shadow Shaman's initial chain of disables and Serpent Ward attacks.
* Short cooldown of 
Wraithfire Blast is ideal for interrupting Shackles.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: 
Phantom Assassin, 
Wraith King, 
Huskar.
Shadow Shaman
* Riki is known for being a successful support killer, something Shadow Shaman is very vulnerable to.
* 
Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. This forces Shadow Shaman to buy a 
Force Staff if he finds himself in this scenario and buy 
Sentry Wards if you have the money.
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 Shaman
* Pudge, Legion Commander and Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.
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.
Shadow Shaman
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
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
* 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.
Shadow Shaman
* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage
Shadow Shaman
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, 
Beastmaster, 
Bloodseeker, 
Clockwerk, 
Doom, Shadow Shaman.
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.
Shadow Shaman
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Tinker
* Heroes with global spells that can reach Tinker anywhere on the map: 
Spectre
Additional:
* 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.
Shadow Shaman
* Hex can be used immediately to destroy Spectre's illusion when she Haunts.
* Shadow Shaman can use Shackles to lock down Spectre for his team.
* Shadow Shaman's Mass Serpent Ward and Ether Shock help him push lanes and end the game early before Spectre can come online and take over the late game.
Shadow Shaman
* Mass Serpent Ward can kill lots of treants if played defensively.
* Mass Serpent Ward, Hex, and Shackles can catch and kill a Nature's Prophet trying to use Teleportation.
Additional:
* Shadow Shaman's Mass Serpent Ward together with Ether Shock can easily kill lots of Treants if played defensively.
* Hex and Shackles can disrupt Nature's Prophet's escape attempts with Teleportation.
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.
Shadow Shaman
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), 
Viper, Shadow Shaman with Hex Breaks talent.
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.
Shadow Shaman
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: 
Broodmother, Phantom Lancer, Chaos Knight, 
Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
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.
Shadow Shaman
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, 
Luna, Naga Siren, 
Mars, 
Jakiro, 
Venomancer, 
Elder Titan, Faceless Void, Rubick, Keeper of the Light, 
Pugna, Invoker, Spectre, 
Alchemist, 
Treant Protector, Lina, 
Oracle, 
Zeus, Shadow Shaman, 
Phoenix, 
Razor, Huskar, Batrider, 
Kunkka, 
Tidehunter, Wraith King, 
Sand King, 
Medusa, Dawnbreaker.
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.
Shadow Shaman
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: Bane, Enigma, Pudge, Shadow Shaman, Dawnbreaker, Warlock, Crystal Maiden.
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.
Shadow Shaman
* Shackles and Hex can both be used on Muerta while in Pierce the Veil, potentially wasting it.
* However, Mass Serpent Ward cannot hurt Muerta while Pierce the Veil is active.
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.
Shadow Shaman
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
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.
Shadow Shaman
* Mass Serpent Ward rips apart Huskar quickly due to his poor armor.
* As soon as Huskar jumps in, he will be vulnerable to Shadow Shaman's disables if he does not have Black King Bar.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Shadow Shaman
* Shackles prevents Chen from acting, and damages him while healing Shadow Shaman, also allowing Shadow Shaman's allies to kill him faster. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Chen while he is disabled. And to make things worse, Chen has no way to cancel Shackles on his own, and must rely on {U:Centaur Conqueror} or {U:Mud Golem} creeps under his control to be able to do so.
* Ether Shock and Mass Serpent Ward can often not only kill Chen's allies before he can save them with 
Hand of God, but they can also be used to destroy Chen's creeps easily thanks to their high damage and area-of-effect.
* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.
Additional:
* Shackles prevents Chen from acting, and damages him while healing Shadow Shaman, also allowing Shadow Shaman's allies to kill him faster. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Chen while he is disabled. And to make things worse, Chen has no way to cancel Shackles on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* Ether Shock and Mass Serpent Ward can often not only kill Chen's allies before he can save them with Hand of God, but they can also be used to destroy Chen's creeps easily thanks to their high damage and area-of-effect.
* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.
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
* 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.
Shadow Shaman
* All of Shadow Shaman's abilities totally ruin Terrorblade: Ether Shock destroys his illusions, Hex prevents him from using 
Sunder or 
Manta Style in bad situations, Shackles not only that prevent him from using Sunder, but he has no way to cancel it and Mass Serpent Ward can help Shadow Shaman push faster than Terrorblade even in 
Metamorphosis.
Additional:
* Ether Shock, Mass Serpent Wards summoned from both, Mass Serpent Ward and Aghanim's Shard upgraded Shackles can do great damage to both, Terrorblade and his illusions.
* Hex prevents Terrorblade from using Sunder or Manta Style in bad situations. Hex can also destroy one of his illusions.
* Shackles can damage Terrorblade and prevent him from using his abilities and items, whether to fight, survive, or dispel it in any way while also healing Shadow Shaman in process. In addition, Terrorblade has no solutions to cancel it. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Terrorblade while he is disabled.
Tinker
* 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.
Additional:
* 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.
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.
Shadow Shaman
* Hex greatly reduces Timbersaw's mobility.
* The stun and damage over time from Shackles mitigates Reactive Armor's HP and armor regen.
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.
Shadow Shaman
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster, Broodmother, Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock, Wraith King.
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.
Shadow Shaman
* Shackles and Mass Serpent Ward instantly destroy 
Refraction
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 Tinkrt 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.
Shadow Shaman
* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
Shadow Shaman
* Shadow Shaman's many disables can lock down Weaver. Even with Linken's Sphere, Weaver might not be able to escape should Shadow Shaman uses Shackles quickly enough following Hex.
* Mass Serpent Wards can make short work of Weaver once he is locked down.
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.
Shadow Shaman
* Shadow Shaman can provide an excellent counter-initiation against her 
Rebound. His abilities can shut down any of her tower dive attempts in the laning phase.
* Shackles keeps Marci stunned for an extended time, wasting her ultimate. A combo with Mass Serpent Ward only makes things worse for her, as her armor is low.
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 and Defense Matrix.
Shadow Shaman
* Shadow Shaman's long disables are effective at kiting and wasting the duration of Battle Trance.
* Mass Serpent Ward are especially effective against Troll Warlord during Battle Trance, as trapping him inside them during the duration is effectively another hard disable, as Troll cannot attack the wards or use Phase Boots to escape.
Tinker
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
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.
Shadow Shaman
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or 
Magnus.
Tinker
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
Tinker
* Lion has an incredibly fragile health pool, making him weak against nukers like Tinker or Oracle.
Shadow Shaman
* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.
Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, Alchemist, 
Earthshaker, Razor, Tinker, Leshrac, 
Queen of Pain
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
* 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.
Shadow Shaman
* In general, squishy heroes that rely on escape often struggle against the amount of disables Shadow Shaman can bring. Queen of Pain, Anti-Mage and Storm Spirit are among these.
Additional:
* Shadow Shaman has many disables to lock down Queen of Pain, preventing her from Blinking away, even through Linken's Sphere or her spell block talent.
* Mass Serpent Ward can tear through Queen of Pain's low health pool once she's locked down by Hex & Shackles.
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 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.
Shadow Shaman
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
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 powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Shadow Shaman
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.
Tinker
* Tinker's Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
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 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.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
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
* 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.
Shadow Shaman
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Tinker
* Laser blinds Lone Druid, making his attacks miss.
Shadow Shaman
* Sniper can easily destroy Mass Serpent Ward from long range
Tinker
* 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
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, Tinker, and 
Templar Assassin.
Shadow Shaman
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Shadow Shaman
* With all 5 Meepos available, all of Shaman's wards will be disposed of very quickly.
Shackles or by using 
Earthbind.
* All of Shaman's disables are based around single target control, and he can at most only disable two Meepos, allowing the rest to easily lay waste to him, be it during the channel duration of
Tinker
*
Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
