Spectre
[wiki] rating: 2.0 (winrate: 53% pickrate: 20%)Night Stalker
[wiki] rating: 1.6 (winrate: 53% pickrate: 6%)Tinker
* Night Stalker can easily find Tinker in the trees during 
Dark Ascension.
* 
Void's mini-stun will stop Rearm and 
Boots of Travel.
* 
Crippling Fear's silence will prevent Tinker from fighting back, as Tinker relies on his spells.
Additional:
* Night Stalker is one of the best heroes to find (and silence) Tinker in the trees during Dark Ascension.
Oracle
* Heroes with long disables, like 
Lion, 
Night Stalker, or 
Legion Commander, can prevent Oracle from using spells or items.
Anti-Mage
[wiki] rating: 1.2 (winrate: 50% pickrate: 15%)Tinker
* Anti-Mage's high mobility from Blink and tendency to build 
Battle Fury makes him strong against split-pushing heroes: 
Nature's Prophet, 
Tinker, and 
Arc Warden.
Additional:
* Tinker is fragile and vulnerable against carries like Anti-Mage.
* 
Mana Break burns away his mana pool and deals bonus physical damage.
* Tinker's massive mana pool makes 
Mana Void deal large amount of damage, and can be used to cancel a Boots of Travel teleport even through spell immunity.
* 
Blink gives Anti-Mage many options, like disjointing Heat Seeking Missiles or leaving March of Machines' area of effect. He can use Blink to wait out of sight for a split pushing Tinker or chase a blinking Tinker into trees.
* Tinker doesn't want any of his spells reflected back at him through 
Counterspell.
Oracle
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and 
Leshrac.
Additional:
* Oracle has minimal damage potential against Anti-Mage due to Counterspell, and may even have some ability damage reflected at himself.
* Anti-Mage can easily overwhelm Oracle with Mana Break and Mana Void.
* Blink allows Anti-Mage to easily chase and take advantage of Oracle's low mobility.
Phantom Lancer
[wiki] rating: 1.2 (winrate: 44% pickrate: 4%)Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as 
Timbersaw, or those who can dispel them, such as 
Phantom Lancer, can kill Oracle unhindered.
Tinker
* Illusion heroes, such as 
Naga Siren, Phantom Lancer, 
Chaos Knight, 
Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without 
Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, 
Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Zeus
[wiki] rating: 1.0 (winrate: 53% pickrate: 15%)Tinker
* Due to Tinker's low health pool, Zeus can easily burst Tinker down, while also cancelling 
Rearm.
* Once Zeus gets Aghanim's Scepter, he will gain 
Nimbus, which allows him to scout out Tinker on the map, especially when he is pushing lanes while hiding in the trees.
Additional:
* Zeus can easily reveal Tinker's location in the trees with 
Thundergod's wrath.
* When Zeus has an Aghanim's Scepter, he can use his Nimbus, together with 
Lightning Bolt to interrupt Tinker's Boots of Travel channelling and cancel Tinker's 
Blink Dagger.
Clockwerk
[wiki] rating: 1.0 (winrate: 52% pickrate: 10%)Tinker
* Rocket Flare can find Tinker if he blinks into the treeline, and Hookshot will prevent him from teleporting out.
* Battery Assault makes Tinker unable to Rearm by stunning him repeatedly.
Additional:
* Clockwerk can easily catch a split pushing Tinker with his 
Hookshot and prevent him from escaping with 
Power Cogs and 
Battery Assault.
* He can find a Tinker hiding in trees with his 
Rocket Flare.
* Clockwerk usually buys a 
Blade Mail, which does lots of damage to Tinker if he gets hit by his abilities (especially March of the Machines).
Vengeful Spirit
[wiki] rating: 1.0 (winrate: 52% pickrate: 8%)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.
Nyx Assassin
[wiki] rating: 1.0 (winrate: 51% pickrate: 3%)Tinker
* His whole skillset acts like a counter to Tinker:
* 
Impale prevents Tinker from blinding Nyx Assassin or fighting back, while giving Nyx' allies time to catch up to Tinker's position.
* 
Mana Burn generally deals more damage to intelligence based heroes like Tinker
* 
Spiked Carapace can stun Tinker at a moment of Nyx Assassin's choosing if March of the Machines has been cast. It is also quite easy to time Spiked Carapace against Heat Seeking Missiles.
* 
Vendetta allows Nyx to approach Tinker in the trees or wait for him in common hiding spots and deal heavy damage to his low armor.
Additional:
* 
March of the Machines and 
Heat-Seeking Missile allow easy Spiked Carapace stuns.
* As a fragile hero that relies on mana and intelligence items, Tinker is vulnerable to Mana Burn.
* Nyx Assassin's stuns can interrupt Rearm and leave Tinker helpless.
Spirit Breaker
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)Tinker
* Tinker relies on his high mobility from Boots of Travel and Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel Rearm and Boots of Travel.
Axe
[wiki] rating: 1.0 (winrate: 50% pickrate: 10%)Oracle
* False Promise will not save an ally from 
Culling Blade if their health is low enough.
* Fate's Edict, offensively or defensively, does little to protect Oracle's allies from the majority of Axe's damage.
Earth Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 8%)Tinker
* Tinker is an easy target for Earth Spirit to initiate on. He likes to split push lanes once he acquieres Boots of Travel and Earth Spirit can jump him with his Rolling Boulder and disable him to buy enough time for his teammates to come and assist Earth Spirit.
* The huge range of Stone Remnant and Rolling Boulder enables Earth Spirit to stop Tinker from teleporting to his fountain since Tinker tends to buy Blink Dagger most of the time to escape.
Silencer
[wiki] rating: 1.0 (winrate: 49% pickrate: 6%)Oracle
* Oracle's reliance on spamming his spells can be easily hindered by Silencer's Arcane Curse.
* Last Word and Global Silence negates Oracle's attempt to save his allies with his spells.
* 
Fate's Edict is useless against Glaives of Wisdom's pure damage.
Tinker
* As Tinker relies heavily on his spells to be effective, 
Last Word and 
Global Silence will render him largely useless.
* 
Arcane Curse effectively prevents Tinker from casting spells during its duration, as he will otherwise suffer heavy damage.
* 
Glaives of Wisdom deal pure damage, which make quick work of fragile heroes like Tinker.
Additional:
* Silencer can stop Rearm, preventing Tinker from spamming his abilities/items or escaping.
Oracle
* Fortune's End can nullify Arcane Curse, Last Word, and Global Silence, if cast at the right time with the right targets.
* Fate's Edict can prevent Silencer from attacking, which he relies on with Glaives of Wisdom, for a lot of his damage.
Storm Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 11%)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.
Lifestealer
[wiki] rating: 1.0 (winrate: 49% pickrate: 11%)Tinker
* 
Rage will dispel Laser's blind and turns him spell immune for the duration so Tinker cannot damage him.
* 
Feast will quickly bring down Tinker due to being so fragile.
Additional:
* Lifestealer's Rage makes him immune to all of Tinker's damage and debuffs.
* Lifestealer can infest any mobile hero (teams usually pick one against Tinker), which ensures that Tinker will die if he is caught.
Shadow Demon
[wiki] rating: 1.0 (winrate: 48% pickrate: 2%)Tinker
* Heroes that can gain vision over trees to catch Tinker: 
Invoker, 
Shadow Demon, 
Batrider
Oracle
* 
Disruption can protect Shadow Demon's allies from Fortune's End, preserving healing or buffs. It can also catch Oracle's allies, allowing 
Shadow Poison and 
Soul Catcher to be used without being dispelled.
* 
Demonic Purge prevents over-time healing during False Promise, such as Purifying Flames and 
Urn of Shadows. If he has Aghanim's Scepter, this issue can persist for longer or on multiple allies.
* It will not, however, prevent healing from instant abilities, items, or auras, making 
Mekansm a good choice against him.
Oracle
* Heroes who can dispel will be able to remove Shadow Poison before Shadow Demon can build up a big stack, or remove Soul Catcher's debuff to instantly bring the health of affected heroes back to a considerable amount: 
Abaddon, 
Slark, Legion Commander, Oracle.
Dazzle
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Tinker
* 
Shadow Wave provides good sustain against Tinker's spammable abilities.
* 
Shallow Grave can stop Tinker from bursting down a target.
Doom
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Oracle
* Supports with useful teamfight or contribution spells will be helpless against Doom: 
Dazzle, Oracle, 
Warlock.
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.
Oracle
* Heroes with the ability to heal allies, or those with good defensive abilities: (
Chen, Dazzle, 
Io, Oracle, 
Omniknight, 
Witch Doctor, 
Winter Wyvern, (Abaddon, etc.
Pudge
[wiki] rating: 1.0 (winrate: 47% pickrate: 22%)Tinker
* He can 
Meat Hook a Tinker hiding in the trees and follow it up with 
Dismember and 
Rot for an easy solo kill, as Tinker doesn't tend to buy survivability items.
* His innate magic resistance and huge health pool from 
Flesh Heap makes it hard for Tinker to deal serious damage to Pudge.
Additional:
* Meat Hook can used to pull Tinker while he is hiding in the trees, and a follow up with Dismember and Rot leads to an easy solo kill, as Tinker doesn't buy many survivability items.
* Flesh Heap makes it hard for Tinker to deal serious damage.
Slark
[wiki] rating: 1.0 (winrate: 46% pickrate: 10%)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.
Bristleback
[wiki] rating: 1.0 (winrate: 44% pickrate: 4%)Oracle
* Fortune's End cannot dispel 
Warpath stacks on Bristleback or 
Quill Spray stacks on allies.
* 
Bristleback can heavily reduce Oracle's damage output. With it, Oracle may accidentally heal Bristleback with Purifying Flames, especially if Bristleback has bonus magic resistance.
Broodmother
[wiki] rating: 0.6 (winrate: 57% pickrate: 2%)Oracle
* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or 
Broodmother.
Visage
[wiki] rating: 0.6 (winrate: 51% pickrate: 1%)Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, 
Templar Assassin's 
Refraction and 
Visage's 
Gravekeeper's Cloak can absorb his burst damage.
Elder Titan
[wiki] rating: 0.6 (winrate: 51% pickrate: 2%)Oracle
* 
Elder Titan's 
Echo Stomp can turn into a 5 second stun on an ally under the effect of False Promise, as it delays all damage and makes it impossible to break the damage threshold of Echo Stomp.
Meepo
[wiki] rating: 0.6 (winrate: 50% pickrate: 1%)Tinker
* Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind. However, Tinker with Aghanim's Scepter can blind multiple Meepos permanently with 
Laser, killing them before Poof can come off of cooldown.
Templar Assassin
[wiki] rating: 0.6 (winrate: 49% pickrate: 6%)Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's Refraction and Visage's Gravekeeper's Cloak can absorb his burst damage.
Legion Commander
[wiki] rating: 0.6 (winrate: 49% pickrate: 14%)Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
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.
Oracle
* Fate's Edict prevents Legion Commander from attacking for a few seconds, potentially saving Oracle's ally.
* 
Fortune's End dispels Press the Attack's healing and attack speed buff, as well as the movement speed bonus from Overwhelming Odds.
* 
False Promise protects allies and prevents Legion Commander from winning Duels and gaining bonus damage.
Additional:
* Provided that the enemy team does not have an 
Axe, Oracle can guarantee that his ally survives for the duration of the Duel with False Promise and has decent nuke potential to help ally to win a Duel. He can also disarm Legion Commander with Fate's Edict.
* Oracle can dispel enemy buffs like 
Overwhelming Odds and Press the Attack with Fortune's End.
Naga Siren
[wiki] rating: 0.6 (winrate: 48% pickrate: 1%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Puck
[wiki] rating: 0.6 (winrate: 47% pickrate: 5%)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.
Kunkka
[wiki] rating: 0.6 (winrate: 46% pickrate: 5%)Tinker
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
* In general, highly mobile heroes like 
Earth Spirit or 
Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Additional:
* 
X Marks the Spot can be used to prevent Tinker from escape with Blink Dagger or Boots of Travel, discourage him from snapping farm and snapping gank. However, in later game, it'll be much more difficult because Tinker can buy 
Black King Bar or 
Linken's Sphere to prevent Kunkka from placing X on him, or 
Eul's Scepter of Divinity to prevent the recall
Timbersaw
[wiki] rating: 0.2 (winrate: 49% pickrate: 5%)Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as Timbersaw, or those who can dispel them, such as Phantom Lancer, can kill Oracle unhindered.
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.
Jakiro
[wiki] rating: -1.6 (winrate: 49% pickrate: 11%)Tinker
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, 
Sniper, Tinker, 
Windranger.
Oracle
* Fate's Edict allowed Oracle to make allies spell immune, allowing him to save allies from Jakiro's spells.
* Fate's Edict can be cast onto Jakiro to disarm him and prevent him from pushing with his Liquid Fire.
* False Promise allows Oracle to free allies from Jakiro's Ice Path.
Magnus
[wiki] rating: -1.6 (winrate: 50% pickrate: 14%)Tinker
* Tinker can break Magnus's Blink Dagger using March of the Machines and Heat-Seeking Missile, therefore delaying any initiation or making Magnus use Skewer or 
Force Staff to initiate. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.
Oracle
* 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.
Necrophos
[wiki] rating: -1.6 (winrate: 51% pickrate: 6%)Oracle
* Fortune's End can dispel 
Ghost Shroud, rending Necrophos vulnerable to physical damage. Also it's worth noting that Necrophos takes additional magic damage when in Ethereal state, which makes Purifying Flames a powerful nuke against him.
* Fate's Edict fully negates the damage from 
Reaper's Scythe, which its own delayed animation makes it relatively easy to predict and nullify.
Additional:
* During the laning stage, Oracle's 
Purifying Flames nullifies any damage that Heartstopper Aura might inflict.
* Fate's Edict and False Promise can protect an ally from Reaper's Scythe.
* Oracle can dispel Ghost Shroud with Fortune's End.
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.
Enchantress
[wiki] rating: -1.2 (winrate: 45% pickrate: 2%)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.
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as 
Skywrath Mage, Crystal Maiden, or Enchantress.
Wraith King
[wiki] rating: -1.2 (winrate: 47% pickrate: 4%)Tinker
* Heroes who rely on physical damage will suffer from Laser: 
Phantom Assassin, Wraith King, Huskar.
Oracle
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, Oracle.
Mars
[wiki] rating: -1.2 (winrate: 48% pickrate: 19%)Tinker
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Oracle
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Phantom Assassin
[wiki] rating: -1.2 (winrate: 48% pickrate: 22%)Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a Black King Bar.
Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Additional:
* The blind from Laser can render Phantom Assassin useless if she is not protected by Black King Bar.
* Tinker is a natural Scythe of Vyse carrier and can permanently disable Phantom Assassin, not giving her chance to activate Black King Bar if she has it.
Crystal Maiden
[wiki] rating: -1.2 (winrate: 51% pickrate: 13%)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.
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Razor
[wiki] rating: -1.2 (winrate: 53% pickrate: 1%)Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Tinker
* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.
Nature's Prophet
[wiki] rating: -1.0 (winrate: 45% pickrate: 4%)Tinker
* Tinker with Rearm and Boots of Travel can teleport and defend towers whenever Nature's Prophet tries to push.
* Laser prevents Nature's Prophet from attacking. Additionally, even with 
Monkey King Bar, Nature's Prophet cannot hit towers and buildings.
* March of the Machines can easily kill an entire wave of Treants, giving Tinker lots of gold.
Rubick
[wiki] rating: -1.0 (winrate: 47% pickrate: 19%)Oracle
* Oracle's high magic damage output can easily take down Rubick's low health pool.
* Because Oracle likes to combine his spells together, the only good 
Spell Steal target he gives is False Promise. This scenario can be avoided by shift queueing Fortune's End and casting it immediately, as it has no cast point, or by staying in the back line of fights if out of mana.
* As a position based hero, Rubick will have a very hard time against Fortune's End due to its absurd range and very long root duration.
Ember Spirit
[wiki] rating: -1.0 (winrate: 47% pickrate: 9%)Oracle
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel 
Flame Guard on Ember Spirit and 
Searing Chains on allies.
* When Ember Spirit is affected by Fortune's End, his 
Fire Remnants move at 0 movement speed.
* Disarming him with Fate's Edict does affect Ember's 
Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
Shadow Fiend
[wiki] rating: -1.0 (winrate: 47% pickrate: 15%)Tinker
* During the laning stage Laser will reduce Shadow Fiend's last hits, preventing him from getting 
Necromastery souls.
* Shadow Fiend has low health and is vulnerable to Tinker's high magic burst.
Additional:
* The blind from Laser prevents Shadow Fiend from attacking for its duration, potentially preventing him from getting a kill.
* Scythe of Vyse can be used to prevent Shadow Fiend from casting Requiem of Souls.
* A combination of Tinker's abilities and his items (like the 
Dagon 5 and 
Ethereal Blade combo) can kill Shadow Fiend quickly.
Troll Warlord
[wiki] rating: -1.0 (winrate: 48% pickrate: 4%)Oracle
* Fate's Edict can disarm Troll, rendering him useless in a teamfight, especially if he has already used Battle Trance.
* Fortune's End and Purifying Flames can provide ample magic damage to help burst down Troll Warlord quickly in the early to mid game.
* False Promise can save an ally from Troll Warlord's initiation, forcing him to switch targets and lose his Fervor stacks, or waste time during Battle Trance.
Witch Doctor
[wiki] rating: -1.0 (winrate: 48% pickrate: 12%)Oracle
* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with Fate's Edict and Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with False Promise.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Tinker
* All of his damage is magical and pure, which makes Cold Embrace a good setup for his nukes.
* Winter's Curse is very hard to cast on Tinker because he usually stays in the back-lines in team-fights. In turn, Tinker has mediocre attack damage and will contribute very little when he is cursed to attack an ally. He can also save his ally under Winter's Curse effect with Ethereal Blade.
Dark Willow
[wiki] rating: -1.0 (winrate: 49% pickrate: 6%)Oracle
* Fortune's End can easily dispel 
Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate 
Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from 
Shadow Realm.
* Fortune's End can dispel the fear effect from 
Terrorize, and it can remove the root from 
Bramble Maze if you're quick enough. Be mindful that Fortune's End only dispels your allies' debuffs on the primary target.
Additional:
* Fortune's End not being disjointable is almost an ensured disable if Dark Willow tries to escape with Shadow Realm. Dispels Cursed Crown and Terrorize.
* Fate's Edict negates all her magic damage in case she catches a single hero.
* False Promise's strong dispel removes Dark Willow's disables.
Dark Seer
[wiki] rating: -1.0 (winrate: 50% pickrate: 2%)Oracle
* Fortune's End can dispel 
Ion Shell, which cripples Dark Seer economy since it's his most efficient tool for farming.
* Fortune's End can dispel 
Surge, effectively slowing his movement speed making him vulnerable to ganks or skirmishes.
Additional:
* Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
Phoenix
[wiki] rating: -1.0 (winrate: 50% pickrate: 11%)Oracle
* Phoenix does significant magic damage over time which can either be dispelled or negated by Fate's Edict.
* Since Phoenix sacrifices some of his health to cast abilities it makes him very vulnerable to Oracle's burst potential
Ancient Apparition
[wiki] rating: -1.0 (winrate: 51% pickrate: 6%)Oracle
* False Promise can prevent the shatter from 
Ice Blast and Fate's Edict can protect an ally from the magical damage over time for a while.
* Oracle can deny allies who are frostbitten. If he uses Purifying Flames to reach the shatter threshold, it will count as a deny.
* Fortune's End can dispel 
Cold Feet on affected allies, preventing them from getting frozen.
Additional:
* False Promise can dispel the stun from Cold Feet and can save an ally that's about to shatter from Ice Blast, even allowing healing with Purifying Flames because of the delayed effect.
* Purifying Flames also allows Oracle to deny his allies if they're affected by Ice Blast. If he brings his allies' health to or below the shatter threshold, it will count as him denying the ally.
* Fate's Edict is good against all of Ancient Apparition's abilities at all stages of the game.
* Fortune's End can dispel Cold Feet from allies.
Slardar
[wiki] rating: -1.0 (winrate: 51% pickrate: 13%)Oracle
* Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
Lone Druid
[wiki] rating: -1.0 (winrate: 51% pickrate: 2%)Tinker
* Laser blinds Lone Druid, making his attacks miss. Furthermore, a Tinker with Aghanim's Scepter is sure to blind both Lone Druid and his bear, negating his ability to root or deal physical damage.
Ogre Magi
[wiki] rating: -1.0 (winrate: 52% pickrate: 18%)Oracle
* Fate's Edict gives full immunity from Ogre Magi's mostly magical damage.
* Fortune's End can dispel Ignite (when used on allies) and Bloodlust (when used on enemies).
* False Promise can dispel Ignite and Fireblast.
Leshrac
[wiki] rating: -1.0 (winrate: 52% pickrate: 6%)Oracle
* Oracle's Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* Fortune's End can stop Leshrac from chasing opponents or running away.
Drow Ranger
[wiki] rating: -1.0 (winrate: 53% pickrate: 16%)Tinker
* Laser applies a blind debuff, making Drow Ranger miss her high damage attacks.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.
Omniknight
[wiki] rating: -1.0 (winrate: 53% pickrate: 2%)Oracle
* Fortune's End's AoE dispel will remove Guardian Angel.
Additional:
* With Fortune's End, Oracle can dispel 
Guardian Angel in an area of effect.
Bloodseeker
[wiki] rating: -1.0 (winrate: 55% pickrate: 5%)Tinker
* Laser can be very effective against 
Bloodrage as the damage will be amplified while the blind prevents Bloodseeker from landing hits.
* Tinker is a natural Boots of Travel carrier and Rearm guarantees him escape from Rupture.
Additional:
* Laser blinds Bloodseeker, preventing him from getting last hits and denies during the laning stage and preventing him from finishing off enemies.
* Tinker always buys Boots of Travel, helping him escape Bloodseeker's early ganks.
* Tinker's heavy magical damage will burst down Bloodseeker during the early to mid game, as he has little health.
Sniper
[wiki] rating: -0.6 (winrate: 43% pickrate: 4%)Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Gyrocopter
[wiki] rating: -0.6 (winrate: 44% pickrate: 1%)Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Keeper of the Light
[wiki] rating: -0.6 (winrate: 44% pickrate: 2%)Oracle
* Heroes with dispels: Legion Commander, Oracle, Slark
Grimstroke
[wiki] rating: -0.6 (winrate: 45% pickrate: 8%)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
Outworld Devourer
[wiki] rating: -0.6 (winrate: 46% pickrate: 3%)Tinker
* Tinker's Laser is useful against Outworld Devourer, as the blind prevents him from landing Arcane Orbs.
Lion
[wiki] rating: -0.6 (winrate: 47% pickrate: 14%)Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
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.
Oracle
* Lion is extremely dependent on his abilities. Silences like 
Silencer's Last Word, magic resistance like Oracle's Fate's Edict, and dispels like Legion Commander's Press the Attack all make his abilities less effective.
Monkey King
[wiki] rating: -0.6 (winrate: 47% pickrate: 8%)Tinker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, Alchemist, 
Earthshaker, Razor, Tinker, Leshrac, 
Queen of Pain
Techies
[wiki] rating: -0.6 (winrate: 48% pickrate: 6%)Tinker
* A common playstyle among Tinkers is to teleport to a lane creep using Boots of Travel and immediately blink into the trees to cast March of the Machines. If Techies can predict where said Tinker would blink after teleporting, he could place strategic Proximity Mines or even Remote Mines in those places. Stasis Traps also prevent Tinker from blinking or teleporting away.
Oracle
* Since Techies' skills are all magical damage, casting Fate's Edict immediately upon hearing the warning sound from 
Proximity Mines and 
Blast Off! can render Oracle or an ally immune to the burst damage from these skills.
* If timed correctly, 
Remote Mines can also be countered using the same technique.
Additional:
* Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage and his Fortune's End dispels Stasis Trap root.
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.
Windranger
[wiki] rating: -0.6 (winrate: 49% pickrate: 19%)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.
Skywrath Mage
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Earthshaker
[wiki] rating: -0.6 (winrate: 50% pickrate: 10%)Tinker
* Tinker's March of the Machines will disable Blink Dagger over a large area.
Bounty Hunter
[wiki] rating: -0.6 (winrate: 50% pickrate: 4%)Oracle

Aphotic Shield and 
Borrowed Time
* Huskar with 
Life Break

Juggernaut with 
Blade Fury
* Legion Commander with Press the Attack

Kraken Shell when damage received reaches the threshold.
Void Spirit
[wiki] rating: -0.6 (winrate: 50% pickrate: 12%)Oracle
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Juggernaut
[wiki] rating: -0.6 (winrate: 50% pickrate: 19%)Oracle
* Heroes with abilities that can save are also effective such as Shadow Demon, Dazzle, Oracle, 
Bane, Pugna, 
Tusk, Winter Wyvern, Io, 
Underlord, Treant Protector and Keeper of the Light.
Venomancer
[wiki] rating: -0.6 (winrate: 50% pickrate: 6%)Oracle
* Fortune's End and False Promise easily dispel many crippling debuffs, such as Venomancer's 
Venomous Gale, or Skywrath Mage's 
Ancient Seal.
Additional:
* Fortune's End can dispel Venomous Gale and Poison Sting from allies.
* Fate's Edict grants 100% magic resistance to target, inhibiting the damage from Venomancer abilities.
Riki
[wiki] rating: -0.6 (winrate: 50% pickrate: 5%)Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Huskar
[wiki] rating: -0.6 (winrate: 50% pickrate: 2%)Tinker
* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Faceless Void
[wiki] rating: -0.6 (winrate: 51% pickrate: 18%)Oracle
* 
Time Walk and 
Backtrack allow Faceless Void to easily negate Oracle's burst damage.
* 
Time Dilation is effective against Oracle's low-cooldown spells. Although dispellable with Fortune's End, it can still catch Oracle off guard if Fortune's End is on cooldown.
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.
Oracle
* Any hero that can nullify effects of Chronosphere: (Omniknight, Keeper of the Light with Aghanim's Scepter during daytime, Winter Wyvern), banishing him or Faceless Void (
Outworld Devourer, Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.
Bane
[wiki] rating: -0.6 (winrate: 51% pickrate: 5%)Oracle
* Heroes with dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight
Sven
[wiki] rating: -0.6 (winrate: 51% pickrate: 14%)Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a Black King Bar.
Mirana
[wiki] rating: -0.6 (winrate: 52% pickrate: 14%)Oracle
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Devourer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Batrider
[wiki] rating: -0.4 (winrate: 49% pickrate: 2%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider
Oracle
* False Promise dispels Flaming Lasso.
* Fortune's End can root Batrider after he uses Flaming Lasso. It can also dispel Sticky Napalm and Flamebreak.
* Fate's Edict when used on a Lasso'd target will leave them immune to magical damage, making it difficult to burst them quickly before the Lasso ends.
Terrorblade
[wiki] rating: -0.4 (winrate: 49% pickrate: 6%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Tinker
* Tinker can single-handedly stop Terrorblade's early-push and quickly clear his illusions with Laser (especially with Aghanim's Scepter) and March of Machines.
* Tinker has perfect tools to reveal Terrorblade from his illusions as well as to burst him down if he is low-health before he will be able 
Sunder.
Additional:
* An Aghanim's Scepter upgraded Laser allows Tinker to blind Terrorblade and illusions.
* Tinker can also clear Terrorblade's illusions and stall his pushing attempts with March of the Machines .
Chaos Knight
[wiki] rating: -0.4 (winrate: 53% pickrate: 7%)Tinker
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game when Tinker's only area of effect damage, March of the Machines, ceases to kill illusions quickly. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Tinker
* With Aghanim's Scepter, Tinker's Laser completely stops Chaos Knight's damage, forcing him to buy either a Black King Bar for his own survivability while leaving his illusions still vulnerable, or a Monkey King Bar leaving him still vulnerable to Tinker's nukes, though improving his damage.
* Tinker rarely finds himself in the middle of a fight, which is where Chaos Knight typically thrives, and even in the rare cases of being so, at level 3 Tinker's constant rearm and blink away can kite and dodge Chaos Knight's spells reliably, so Chaos Knight has very little catch against Tinker's mobility. This gives Tinker impunity to create more chaos in a teamfight than Chaos Knight can control, laying down the field with March of the Machines and constantly being hit by rockets and lasers.
Additional:
* Tinker's Aghanim's Scepter upgraded Laser can blind him and all of his Phantasm illusions.
Invoker
[wiki] rating: 0.0 (winrate: 49% pickrate: 20%)Tinker
* Heroes that can gain vision over trees to catch Tinker: Invoker, Shadow Demon, Batrider
Additional:
* Tinker is relatively helpless against Invoker, as his Rearm and Boots of Travel can be easily interrupted by Invoker's long range disables, even if he blinks away.
Tinker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
Luna
[wiki] rating: 0.0 (winrate: 50% pickrate: 4%)Tinker
* Luna can easily prevent Tinker from escaping with Boots of Travel or Rearm with 
Lucent Beam.
* Luna can also quickly tear Tinker to shreds with 
Eclipse as soon as he jumps in with Blink Dagger.
Tinker
* Tinker's March of the Machines and Laser both destroy Luna's small health pool and make it hard for Luna to initiate with Eclipse (and making it hard to land glaives in Laser's case).
* Since Tinker typically buys Blink Dagger, Luna has a hard time catching him despite her high movement speed.
* Tinker can easily disable and nuke Luna down with 
Dagon or Scythe of Vyse before she can use Lucent Beam or Eclipse.
Pugna
[wiki] rating: 0.0 (winrate: 51% pickrate: 6%)Tinker
* 
Nether Ward discourages Tinker from using abilities and items due to its high damage against heavy mana usage.
Oracle
* Most of Pugna's damage is magical, which can get blocked by Fate's Edict's 100% magic resistance.
* Oracle has two abilities that apply a dispel, which can easily remove Decrepify on his ally or Oracle.
* Oracle has a very long Attack Range and a very low Base Attack Time, which enables him to take down Nether Ward swiftly from long distance.
Beastmaster
[wiki] rating: 0.0 (winrate: 52% pickrate: 3%)Tinker
* Beastmaster's Hawk can find Tinker easily while he is pushing or blinking into trees.
Oracle
* False Promise effectively nullifies Primal Roar's single-target initiation on allies.
* Purifying Flames kills Beastmaster's Hawk instantly and Boar with two casts.
Clinkz
[wiki] rating: 0.0 (winrate: 56% pickrate: 9%)Oracle
* Heroes who can take advantage of Oracle's low mobility or catch him out of position, such as 
Clinkz and 
Anti-Mage, can easily pick him off.
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.
Oracle
* Oracle's burst damage is ineffective against
Dispersion.
* Disarm provided by Fate's Edict is not as significant debilitation for Spectre as it might be for other carries since She can do damage even without landing attacks.
Tinker
* His global teleportation with
Boots of Travel and 
Rearm is easily countered with Haunt, and Spectre can reach him anywhere on the map.
Laser's blind isn't reliable, since Desolate cannot miss.
* He is squishy, and if alone Desolate will kill him very fast.
*
