Drow Ranger
* Nyx Assassin has a lot of burst damage from his 
Impale, 
Mind Flare, 
Dagon, and the bonus damage from 
Vendetta. All of this damage is enough to kill Drow Ranger.
* Nyx Assassin is usually invisible most of the time thanks to his ability Vendetta, which allows him to gank Drow Ranger easily.
* However, 
Gust is extremely dangerous for Nyx Assassin, as it's silence can render Nyx Assassin unable to lock down Drow Ranger. And if Gust hits Nyx Assassin while he is invisible with Vendetta, Drow Ranger will be able to detect him and foil his ganking attempts on her because Gust reveals invisible units.
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.
Drow Ranger
* A well-timed 
Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* 
Essence Shift is very detrimental for Drow Ranger as the loss of agility means that Marksmanship will also suffer from getting weakened.
* 
Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* 
Pounce counteracts Frost Arrows's slow, and also allows Slark easily pin Drow Ranger down or flee from her.
* 
Depth Shroud from 
Aghanim's Shard will allow Slark to save both, himself and his allies and will also allow them to freely fight back against Drow Ranger without her noticing them.
Additional:
* Pounce and items like 
Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her 
Marksmanship bonus.
* Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.
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.
Drow Ranger
* 
Meat Hook brings Drow Ranger to Pudge, disabling Marksmanship and dealing a huge amount of damage when combined with 
Rot and 
Dismember.
* Rot keeps Pudge close to Drow Ranger, continuously disabling Marksmanship.
Additional:
* Meat Hook can pull Drow Ranger to Pudge, disabling her Marksmanship.
* Following up with Dismember will prevent Drow Ranger from using Gust or Shadow Blade.
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.
Drow Ranger
* Spectre can easily close the distance on Drow Ranger with 
Haunt and stick on her with 
Spectral Dagger, effectively disables her Marksmanship.
* Spectre does not care if silenced by Gust, since Spectre will catch her up regardless.
* 
Dispersion can reflect some damage back to Drow Ranger should she chooses to attack.
* Be careful once she got her 
Silver Edge as an attempt to shut you down.
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.
Drow Ranger
* Heroes with weaker mobility will struggle to keep up with Night Stalker: 
Gyrocopter, 
Ursa, 
Drow Ranger
Tinker
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
Additional:
* 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.
Drow Ranger
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as 
Phantom Assassin, 
Spirit Breaker, and 
Tusk are effective at limiting her power and bursting her down.
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.
Drow Ranger
* Drow Ranger's low mobility and lack of defensive abilities make her an easy gank target in the early to mid-game.
* A Dueling Drow Ranger will lose her precious Marksmanship, reduce her damage output significantly, and will more likely lose that Duel.
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
Drow Ranger
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, 
Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Tinker
* Heroes that can gain vision over trees to catch Tinker: 
Invoker, 
Shadow Demon, 
Batrider.
Drow Ranger
* 
Repel can be used to dispel Gust on the allies affected by it.
* In team fights, 
Guardian Angel renders Drow Ranger's physical damage useless, and Drow Ranger has no way to purge it. And to make thing worse, Drow Ranger is not a common 
Nullifier wielder to counter this problem at all.
Drow Ranger
* Magnetic Field protects Arc Warden and allies from Drow Ranger's ranged attacks. She most likely will not enter the field since she will lose Marksmanship's bonus agility.
* Beware however, as Marksmanship procs will still hit since they have True Strike, so the most damaging arrows will still hit you inside Magnetic Field.
Additional:
* 
Flux along with 
Spark Wraith allows Arc Warden to quickly burst down Drow Ranger due to her low health.
* However, Drow Ranger can bypass 
Magnetic Field's evasion bonus thanks to Marksmanship.
Drow Ranger
* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.
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
* 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.
Drow Ranger
* Drow Ranger's lack of mobility and area-of-effect abilities makes her easy prey for Broodmother and her Spiderlings.
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
* 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
* 
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
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.
Drow Ranger
* 
Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves's speed causes the knockback from Gust to be ineffective.
* Drow Ranger lacks escapes and loses her Marksmanship when someone is near her. Lycan can take advantage of these weaknesses of Drow Ranger.
Tinker
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
Drow Ranger
* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with 
Aghanim's Scepter.
* Mirana can dodge Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.
Drow Ranger
* 
Snowball and 
Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.
* 
Tag Team allows Tusk to slow her down and land a killing blow on her.
* 
Walrus PUNCH! slows Drow Ranger and deals a huge amount of damage to her, due to her low health (and low armor without Marksmanship, since Tusk can quickly close the gap to Drow Ranger).
Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Drow Ranger
* Invisible heroes are very difficult for Drow Ranger to deal with such as 
Bounty Hunter, Riki and heroes who commonly buy a Shadow Blade.
Drow Ranger
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, 
Clinkz, Drow Ranger, 
Faceless Void, Gyrocopter, 
Juggernaut, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, Phantom Assassin, 
Phantom Lancer, Riki, Shadow Fiend, 
Slark, Sniper, 
Terrorblade, Troll Warlord, 
Weaver.
Drow Ranger
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: 
Primal Beast, 
Axe, 
Centaur Warrunner.
Drow Ranger
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, 
Lina, 
Rubick, etc.
Tinker
* Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
Drow Ranger
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: 
Huskar, Drow Ranger, 
Lion, 
Elder Titan, etc.
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.
Drow Ranger
* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.
Drow Ranger
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, Centaur Warrunner.
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
* 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
* 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.
Drow Ranger
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Drow Ranger
* 
Phantom Rush lets Phantom Lancer get close quickly and disable Marksmanship.
* As Phantom Lancer commonly buys 
Manta Style, he can easily dispel Gust and then chase after Drow Ranger.
* Because Phantom Lancer is a natural 
Diffusal Blade carrier, he can easily burn Drow Ranger's mana and render her unable to use Frost Arrow and Gust to save herself.
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
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider.
Drow Ranger
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies completely on agility to be effective.
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.
Drow Ranger
* 
Berserker's Call forces Drow Ranger to attack Axe up close, disabling her Marksmanship bonus.
* 
Counter Helix occurs more often with Drow Ranger's high attack speed.
* 
Culling Blade is a dangerous ability against a low health hero like Drow Ranger.
Drow Ranger
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Drow Ranger
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
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
* 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.
Drow Ranger
* 
Static Link weakens Drow Ranger's attack damage while strengthening Razor's attack damage.
* 
Plasma Field & 
Storm Surge keeps Razor close to Drow Ranger, continuously disabling Marksmanship.
Tinker
* Heroes who rely on abilities to deal damage (e.g. 
Timbersaw, Tinker) can fight a Razor even after Static Link.
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.
Drow Ranger
* Heroes who rely on passive abilities and attacks, such as Drow Ranger, 
Wraith King, and 
Lone Druid, can render Silencer useless. But remember that a smart Silencer will most likely buy Silver Edge to counter this if he is played as carry.
Drow Ranger
* 
Blink Strike gets Riki close to Drow Ranger and disable Marksmanship.
* 
Cloak and Dagger allow Riki stay close to Drow Ranger without her noticing him, which allows him to disable Marksmanship.
Additional:
* With Blink Strike, Riki can get close to Drow Ranger and disable her Marksmanship, and Smoke Screen will prevent her from using Gust.
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.
Drow Ranger
* Often you can burst Drow Ranger down before she has a chance to try and Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.
Drow Ranger
* Heroes reliant on abilities to output damage or escape can be shut down by Gust: 
Queen of Pain.
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:
* 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.
Drow Ranger
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, 
Clockwerk, Drow Ranger, 
Abaddon, Faceless Void, Weaver, 
Outworld Destroyer.
Drow Ranger
* 
Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* 
Berserker's Blood and 
Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Drow Ranger
* Drow Ranger has a very low health pool, allowing Lion to burst her down.
* Lack of any innate escape mechanism makes her an easy target for Lion's disables.
* Early on she can't deal as much damage to be life threatning. Her Gust is her best weapon against Lion.
Tinker
* Lion has an incredibly fragile health pool, making him weak against nukers like Tinker or 
Oracle.
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.
Drow Ranger
* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, 
Bloodseeker, 
Disruptor and many others.
* 
Doom, as usual, fits this description nicely.
Drow Ranger
* As long as Mars is facing her with Bulwark, even if pushed away with Gust, Drow Ranger will do no effectual damage against him. Mars' ability to endure her onslaught usually gives him enough time to cast Arena of Blood, of which she has a very slim chance surviving without Gust.
* With Bulwark's active ability, Mars can protect allies pursued by Drow Ranger by redirecting her projectiles to his shield instead.
Tinker
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Drow Ranger
* Monkey King can scout Drow Ranger's positioning from the trees, and can jump on her without much trouble, disabling Marksmanship
* She lacks innate mobility to escape from Wukong's Command, whose bonus armor gives MK one extra edge in the fight
Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, 
Alchemist, 
Earthshaker, 
Razor, Tinker, Leshrac, Queen of Pain
Drow Ranger
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger, Bane, Necrophos, Crystal Maiden.
Additional:
* 
Reality Rift will disable Drow Ranger's Marksmanship, along with 
Chaos Bolt he can keep her locked for enough time to be killed.
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.
Drow Ranger
* A well-timed Gust will prevent Windranger from escaping or counter-initiating with 
Windrun.
* Drow Ranger commonly buys Shadow Blade or Silver Edge, which allows her to escape from 
Focus Fire. 
Monkey King Bar, a situational item on Drow Ranger, counters Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
Additional:
* A well-timed Gust prevents Windranger from escaping or counter-initiating with Windrun.
* Drow Ranger can combine 
Frost Arrows and 
Eye of Skadi to effectively slow down Windranger if she tries to escape with Windrun, since both slow effects stack with each other.
* Drow Ranger commonly buys Shadow Blade or Silver Edge, which allows her to escape from Focus Fire. Drow Ranger can also buy Monkey King Bar to counter Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
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.
Drow Ranger
* Clinkz has no stun and likes to keep his distance from targets, making Marksmanship very deadly.
* Clinkz also has low health, making him a perfect hero to initiate onto with Gust.
* Gust can also prevent Clinkz from using 
Burning Barrage.
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.
Drow Ranger
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, 
Magnus, 
Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
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.
Drow Ranger
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
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.
Drow Ranger
* Heroes with low health are especially vulnerable to Marksmanship's high damage output: Clinkz, Crystal Maiden.
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.
Drow Ranger
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, 
Night Stalker, Drow Ranger, 
Doom .
Tinker
* Tinker's Laser is useful against Outworld Destroyer, as the blind prevents him from landing Arcane Orbs.
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.
Drow Ranger
* Dragon Knight has no built-in disengage from Frost Arrows, and Marksmanship procs ignore base armor, bypassing Dragon Knight’s durability for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With Aghanim's Scepter, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an Eye of Skadi).
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.
Drow Ranger
* A well-timed Gust will prevent Rubick from casting abilities from 
Spell Steal, and his lack of capabilities and low health pool usually dies very quickly.
* Drow Ranger can dispel 
Fade Bolt's reduction debuff with Manta Style.
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.
Drow Ranger
* Gust can shut down most of Dawnbreaker's abilities, rendering her useless.
* Frost Arrows followed by a high attack speed, makes it hard for Dawnbreaker to escape.
Drow Ranger
* Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.
Drow Ranger
* Drow Ranger can use Gust to push back Juggernaut before he can get in range to use 
Omnislash or 
Blade Fury.
Drow Ranger
* A well-timed Gust will prevent Weaver from escaping, and a silenced Weaver usually dies very quickly.
* Weaver gains a lot of armor, which is bypassed by Marksmanship.
Additional:
* A well-timed Gust followed by Frost Arrows will prevent Weaver from escaping with Shukuchi. A Weaver silenced for more than 3 seconds usually dies very quickly.
* Due to her high attack speed, Drow Ranger can easily kill The Swarm beetles.
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.
Drow Ranger
* 
Black Hole while definitely a threat to Drow Ranger, is very hard to land as she likes to keep her distance from allies and enemies alike. And if not caught in it, will kill Enigma very quickly due to his low health.
* 
Malefice can be removed with a Manta Style.
* Drow Ranger being a fairly low health, high armored agility carry doesn't take much damage from 
Midnight Pulse as others would.
* 
Demonic Conversion units die very quickly to Marksmanship or even just regular attacks not far into the game within 2 or 3 hits.
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 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
* 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.
Drow Ranger
* Heroes with high base damage (Morphling, 
Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.
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.
Drow Ranger
* 
Metamorphosis will not match the range of Drow Ranger and he will struggle to do damage to her if she is not locked down already by someone else.
* 
Conjure Image will be destroyed very quickly due to Marksmanship.
* Terrorblade generally likes to be the big bad late game carry who sits in the middle of the fight and kills whoever is closest, which is very unlikely to be Drow Ranger therefore making it likely she will be going on him in teamfights.
* Terrorblade's high base armor and agility items makes him very vulnerable to Marksmanship.
Additional:
* Even though Drow Ranger's damage output is 100% physical, Marksmanship allows Drow Ranger to pierce Terrorblade's high natural base armor and when upgraded with Aghanim's Scepter, it will allow her to clear Terrorblade's illusions.
* Gust can prevent Terrorblade from using 
Sunder.
* Since Terrorblade doesn't like to buy armor items like 
Assault Cuirass, he will be very vulnerable to Drow Ranger's high physical burst damage.
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 either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, Ursa, Void Spirit.
Drow Ranger
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Drow Ranger
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, Arc Warden
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
* 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.
Drow Ranger
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, 
Silencer, Drow Ranger, Skywrath Mage.
Drow Ranger
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Tinker
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Drow Ranger
* Range-reliant heroes: Sniper, Drow Ranger
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.
Drow Ranger
* Heroes who outrange Drow Ranger such as Sniper, Tinker.
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
* 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.
Drow Ranger
* None of Anti-Mage's skills are that effective against Drow Ranger. Gust prevents him from Blinking in or out, Counterspell is totally useless against Drow's physical damage, and as she usually doesn't have a high mana pool, Mana Break and Mana Void don't do much either.
* Be careful however that Anti-Mage may eventually farm enough to Blink on top of you and kill you straight away, considering you have no natural tools to escape from him.
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.
Drow Ranger
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and Tusk are effective at limiting her power and bursting her down.
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 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.
Drow Ranger
* Heroes with silence: Death Prophet, Riki, Drow Ranger.
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.
Drow Ranger
* Morphling can use Waveform to close the gap between him and Drow Ranger, but should be careful of Gust and Frost Arrows.
* Morphling is a natural Manta Style carrier, which dispels the silence from Gust.
Drow Ranger
* 
Attribute Shift (Strength Gain) may not be quick enough to fend off an attacking Drow Ranger.
* Morphling likes to sit on low health with high agility, something Drow Ranger does not particularly care for and will still hit him hard with Marksmanship procs.
* 
Morph is a similar story, none of Drow Ranger's spells are particularly good against her.
Drow Ranger
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, Drow Ranger, 
Lifestealer, Anti-Mage, Alchemist, 
Lycan, Clinkz, Sniper.
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
* 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.
Drow Ranger
* Drow Ranger can be difficult to get on top of, thanks to her Frost Arrows and Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive Marksmanship, which is not disabled by Doom.
Drow Ranger
* 
Time Walk can be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void can also lock down Drow Ranger with 
Chronosphere before she has the chance to retaliate due to her low health pool.
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.
Drow Ranger
* Getting trapped in Power Cogs usually means the end for Drow Ranger.
Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
Power Cogs and 
Battery Assault keep Drow Ranger from escaping.
Additional:
*
*
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.
Tinker
* Rocket Flare can find Tinker if he blinks into the treeline, and Hookshot will prevent him from teleporting out.
Rearm by stunning him repeatedly.
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.
Blade Mail, which does lots of damage to Tinker if he gets hit by his abilities (especially March of the Machines).
* Battery Assault makes Tinker unable to
Additional:
* Clockwerk can easily catch a split pushing Tinker with his
