Warlock
* Supports with useful teamfight or contribution spells will be helpless against Doom: 
Dazzle, 
Oracle, 
Warlock.
Additional:
* 
Doom will not only prevent Warlock from casting his abilities in team fights, but also it reduces the healing from Shadow Word.
* 
Devour allows Doom to acquire a stun from neutral creeps, allowing him to interrupt Upheaval without having to use Doom.
Clinkz
* 
Scorched Earth deals damage to Clinkz during Skeleton Walk.
* Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include 
Chaos Knight, 
Spirit Breaker, 
Riki, and more.
Clinkz
* 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.
Additional:
* Smoke Cloud prevents the use of 
Death Pact, 
Searing Arrows and 
Skeleton Walk, so Clinkz can neither defend himself against Riki nor fight back effectively.
* It's hard to gank Riki as Clinkz has to find him first.
Clinkz
* Clinkz will often roam the map alone, and Treant Protector's 
Nature's Guise allows him to set up kills with his allies on Clinkz from invisibility.
* Treant Protector's very high damage allowing him to trade hits or contest last hits with Clinkz, while 
Living Armor can be used to sustain the harass.
* Living Armor protects any of Treant's allies ganked by Clinkz.
* In teamfights, Treant Protector's 
Overgrowth can disarm Clinkz, preventing him from turning invisible and holding him in place even if he has a 
Black King Bar.
* 
Leech Seed slows Clinkz, preventing him from repositioning or fleeing away from danger.
Clinkz
* The long silence at night prevents Clinkz from escaping with invisibility if Night Stalker can sneak up on him. He also has really low base health, so Night Stalker can usually kill him alone during one cast of Crippling Fear at night.
Clinkz
* 
Cold Embrace can heal herself or an ally, as well as protecting them from Clinkz's physical attacks and wasting his mana if Searing Arrows is on autocast.
* 
Winter's Curse allows Winter Wyvern to turn Clinkz's high damage and high attack speed against his allies, or take advantage of Clinkz's fragility if he can't use Skeleton Walk.
Warlock
* With God's Strength, Warlock's Golem from 
Chaotic Offering will go down in a matter of seconds. The two weaker golems granted by 
Aghanim's Scepter will fare worse due to 
Great Cleave hitting both.
* Aghanim's Scepter upgraded 
Storm Hammer Aghanim's Scepter can dispel 
Shadow Word.
Additional:
* 
God's Strength combined with Great Cleave destroys Chaotic Offering golems within seconds.
* 
Warcry gives Sven and his allies armor to help against Warlock's Golem's heavy physical damage and movement speed to help escape Upheaval.
* Storm Hammer disrupts Upheaval.
Clinkz
* Skeleton Walk is not enough to outrun Bloodseeker, and is detected by Thirst.
* Because of his low health and high damage output, Clinkz will get obliterated by 
Blade Mail
Additional:
* 
Thirst reveals Clinkz if he tries to escape with Skeleton Walk with low health. It also allows Bloodseeker to match or exceed Clinkz's speed.
* 
Rupture negates the mobility provided by Skeleton Walk in any attempt to escape or reposition in fights.
* Bloodseeker can easily build items to counter Clinkz, including 
Talisman of Evasion upgrades, Blade Mail, and armor items.
Clinkz
* Lina's damage burst can quickly kill Clinkz before he saves them with Skeleton Walk.
* Fiery Soul attack speed bonus removes 
Burning Army easily in all stages of the game.
Warlock
* Weaver's 
Shukuchi allows him to escape from Warlock's Upheaval with high move speed.
* 
Time Lapse allows Weaver to ignore damage from Warlock's Golem and escape.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Clinkz
* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* 
Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use 
Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a 
Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in Skeleton Walk.
Warlock
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, 
Phantom Lancer, 
Terrorblade, 
Naga Siren, 
Broodmother, Warlock, 
Visage, 
Nature's Prophet, 
Shadow Shaman, 
Lycan, 
Wraith King.
Warlock
* 
Impale and 
Spiked Carapace interrupts Upheaval with ease.
* Warlock's low health pool, mobility, and high intelligence gain makes him a prime target for Nyx Assassin's burst damage.
Warlock
* Because Warlock's abilities are all active abilities, Silencer can make his impact minimal.
* 
Arcane Curse prevents Warlock from using his abilities without increasing it's duration, which since all of Warlock's abilities are actives it is very effective against him.
* 
Last Word can prevent Warlock from casting his Fatal Bonds, Chaotic Offering, and Upheaval combo.
* 
Global Silence can nullify Warlock's impact in fights by preventing him from casting Fatal Bonds and Chaotic Offering, or by interrupting his Upheaval.
Warlock
* 
Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* 
Fatal Bonds and Shadow Word can be dispelled by Dark Pact.
Clinkz
* Slardar can reveal Clinkz with 
Corrosive Haze and make him easy to kill, and his 
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's 
Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's 
Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
Warlock
* 
Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from 
Summon Wolves.
Clinkz
* Zeus can reveal Clinkz with 
Lightning Bolt.
* He is vulnerable to Zeus's magical nukes, due to his low health pool.
Clinkz
* By using 
Morph, Morphling can use Burning Barrage and Searing Arrows to counter Clinkz himself.
* 
Waveform can allow Morphling to easily chase down Clinkz.
* Clinkz's low health pool also makes him vulnerable to Morphling's magical nukes, especially his 
Ethereal Blade and 
Adaptive Strike combo.
Clinkz
* 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.
Warlock
* 
Ursa can shred Warlock's Golems in a few seconds with 
Fury Swipes and 
Overpower.
Clinkz
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:
Clinkz, Riki, 
Treant Protector, etc.
Additional:
* 
Track reveals Clinkz if he tries to escape with Skeleton Walk, allowing Bounty Hunter to gain lots of gold if he kills Clinkz.
* 
Jinada with physical damage items can quickly kill Clinkz due to his low health.
Warlock
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: 
Beastmaster, Broodmother, 
Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Additional:
* 
Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.
Clinkz
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, 
Sniper, 
Enchantress.
Clinkz
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: 
Weaver, 
Queen of Pain, 
Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Warlock
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like 
Death Prophet, 
Puck, and the aforementioned 
Silencer.
Clinkz
* In general, Brewmaster's Cinder Brew and Thunder Clap makes him good against physical damage carries: Ursa, Clinkz, 
Faceless Void, 
Troll Warlord, 
Templar Assassin, Phantom Assassin.
Clinkz
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: 
Brewmaster, Dazzle, 
Tidehunter.
Warlock
* Heroes with channeling spells are very easy targets for Jakiro's abilities: 
Crystal Maiden, 
Dawnbreaker, Enigma, 
Pudge, 
Shadow Fiend, Shadow Shaman, Warlock.
Warlock
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, 
Witch Doctor, Warlock or Shadow Fiend.
Clinkz
* Heroes who rely on invisibility, such as 
Bounty Hunter, Clinkz, 
Mirana, 
Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
Warlock
* 
Mana Break prevents Warlock from casting his spells, particularly in the laning phase.
* 
Blink allows Anti-Mage to escape from Upheaval.
* 
Counterspell reduces damage from Shadow Word and Warlock's Golem's 
Permanent Immolation passive. Additionally, it can reflect Shadow Word and Fatal Bonds.
* 
Mana Void deals heavy damage after Anti-Mage has drained Warlock's large mana pool.
Clinkz
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, 
Slark, Shadow Fiend, Clinkz, 
Bristleback Nyx Assassin, 
Magnus
Clinkz
* Anti-Mage's Counterspell provides no protection against Clinkz's physical damage output.
* Clinkz can easily rush an 
Orchid Malevolence to prevent Blinking, although Anti-Mage can easily dispel it via 
Manta Style.
* Clinkz does heavy damage to towers, and can take map control away from Anti-Mage to limit the space he has to farm early game. If Clinkz is ahead he is capable of ending the game before Anti-Mage becomes a threat. He can also match Anti-Mage's ability to split push.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Clinkz
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, Dazzle, Tidehunter.
Warlock
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.
Clinkz
* 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.
Additional:
* The extra damage from Searing Arrows is largely blocked by Dragon Knight's armor.
* Clinkz has too low health to survive a gank.Getting stunned keeps him down long enough for a reaction.
* Breathe Fire reduces his damage, as he almost exclusively deals physical damage.
Clinkz
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, 
Anti-Mage, Broodmother, 
Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Warlock
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, 
Ancient Apparition, 
Grimstroke, Witch Doctor
Clinkz
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, 
Drow Ranger, Clinkz
Warlock
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: 
Earth Spirit, Spirit Breaker, 
Tusk, Bounty Hunter, Riki, Warlock.
Additional:
* Warlock can cast Upheaval when Templar Assassin uses 
Meld, preventing her from escaping at the right moment.
* Warlock can also send his Warlock Golem near where she used Meld, preventing escape by 
Blink Dagger due to the Warlock Golem's Permanent Immolation.
* Warlock's Golem's Permanent Immolation will burn away 
Refraction with its damage over time.
Clinkz
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, 
Sven, Clinkz, 
Windranger, 
Alchemist, Dragon Knight, 
Legion Commander
Clinkz
* 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.
Warlock
* 
Ice Blast cancels Warlock's Golem's and Shadow Word's healing.
* 
Cold Feet stuns Warlock if he stands in place, forcing him to stop channeling Upheaval immediately or be forced to stop channeling it by it's stun.
Clinkz
* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.
Clinkz
* 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.
Warlock
* 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.
Clinkz
* 
Hex and 
Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* 
Finger of Death quickly kills Clinkz due to his low health.
Warlock
* 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.
Clinkz
* Spectre can instantly escape Burning Army or hunt Clinkz with 
Haunt.
* Spectre can catch up to him with 
Spectral Dagger, even if he uses Skeleton Walk.
* 
Desolate allows Spectre to hit Clinkz through Skeleton Walk.
* 
Dispersion makes Spectre tanky and also reflects some damage back to Clinkz.
Additional:
* Spectre can catch Clinkz with Spectral Dagger, even if he uses Skeleton Walk.
* Spectre can instantly reach a ratting Clinkz with Haunt.
* Desolate's damage will melt him quickly, as he's alone most of the time.
Clinkz
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver
Warlock
* Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* Upheaval makes retreating with 
Scurry difficult.
Clinkz
* Clinkz's item build often counters Hoodwink, including Black King Bar, 
Monkey King Bar, 
Heaven's Halberd, and 
Scythe of Vyse.
* Skeleton Walk can quickly escape Hoodwink abilities.
Warlock
* Warlock Golems do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using 
Life Break, because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allows Warlock's team to gather their wit and retaliate.
* After using Life Break to jump in, Huskar will not have any means to escape Upheaval. Which since he is an attack-dependent hero, this will nullify his impact in fights.
Clinkz
* Huskar's 
Berserker's Blood provides no protection against Clinkz's physical damage output.
* Huskar has no way to disrupt Clinkz's attacks and no way to kill Clinkz alone, as Clinkz can easily go invisible, teleport away, or even fight back.
* Clinkz will often build the items that counter Huskar and the items he usually builds. These include Black King Bar or Monkey King Bar for Heaven's Halberd, or a disable item like Scythe of Vyse or 
Bloodthorn to prevent him from using 
Inner Fire to disarm.
Warlock
* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole. It also goes through Black King Bar and ignores Linken's Sphere.
* Fatal Bonds and 
Aghanim's Shard upgraded Shadow Word can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team. Also,their constant damage will put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere, Warlock will always be able to cancel the channeling of 
Black Hole.
* Enemies often get clumped up around Black Hole to hit your allies, giving you a perfect opportunity to cast Fatal Bonds, Chaotic Offering, and Upheaval on multiple enemies.
Clinkz
* Despite Clinkz's fragility, his harassment in the early game can be devastating; as he can kite Enigma and his Eidolons and claim their bounty with Burning Barrage and 
Tar Bomb.
* Clinkz often goes for a disabling item like Bloodthorn or 
Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar. Gleipnir can also root Enigma, preventing him from using Blink Dagger to escape from Clinkz.
* Even with Black King Bar, Clinkz can still easily kill Enigma as all of his abilities ingore spell immunity, and Enigma is a very easy target for Burning Barrage, which means Clinkz can solo Enigma at any stage of the game unless Clinkz is caught in Black Hole.
Warlock
* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage, Beastmaster, Warlock, Wraith King. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.
Clinkz
* Clinkz's Skeleton Walk allows him to easily sneak on Chen and bypass his creeps. It also allows him to escape from them.
* Clinkz can easily kill Chen's creeps with Death Pact and gain gold, health, damage and abilities from them when upgraded with Death Pact Steal creep abilities talent.
* Clinkz naturally loves buying Gleipnir, which allows him to easily root Chen and his creeps and to kill them more easily with Burning Barrage from Aghanim's Shard.
* Clinkz can kill Chen or any of his allies with his physical damage burst from 
Strafe, Tar Bomb and Burning Barrage from Aghanim's Shard before he can use Hand of God. Especially when Clinkz has Gleipnir and 
Daedalus. Clinkz can also buy Bloodthorn to prevent Chen from even trying to use Hand of God.
Warlock
* 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.
Clinkz
* Strafe, Tar Bomb and Burning Barrage from Aghanim's Shard allow Clinkz to quickly kill Io due to its low armor.
* Clinkz iz a hero that very often goes for Orchid Malevolence, and its upgrade Bloodthorn. Alternatively, Clinkz also loves to buy Gleipnir. And if Clinkz has both of them, he will be able to root and silence Io and prevent him from escaping with either 
Tether or 
Relocate.
Warlock
* Viper cannot interrupt heroes with powerful channeling abilities: 
Bane, Enigma, Shadow Shaman, Warlock
Clinkz
* Clinkz does not have any passive abilities at all, making 
Nethertoxin nearly useless.
* Viper's 
Corrosive Skin provides no protection against Clinkz's physical damage output.
Warlock
* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.
Clinkz
* Clinkz relies heavily on the physical damage provided by Burning Barrage and Searing Arrows, which completely overrides the capabilities of Rage.
* Lifestealer's lack of disables will struggle to pin Clinkz down while in Skeleton Walk, and can allow Clinkz to kite him.
Warlock
* Warlock often stays back and counter-initiates by dropping his Chaotic Offering on Earthshaker and his allies.
Clinkz
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, 
Storm Spirit
Clinkz
* Nature's Prophet is often by himself. Clinkz can use invisibility to hunt him down and kill him, although a Quelling Blade may be needed to cut through his 
Sprout. Orchid Malevolence may also be needed if 3-4 seconds are not enough time to kill him, as he can teleport away.
* Clinkz can match Nature's Prophet's ability to split push.
Warlock
* Fatal Bonds links the Meepos together, which combined with area of effect damage or Cleave will be devastating.
Warlock
* Warlock has strong counter initiation which reduces Marci's effectiveness throughout the game.
* Fatal Bonds cancels Blink Dagger, which means Marci can move in and out of fights less effectively.
* Chaotic Offering paired with Upheaval provides a ministun, a movement slow and paired with Fatal Bonds has the potential to deal a lot of damage to Marci while she jumps on a target. The ministun also means that Marci will have a harder time casting Rebound. If Warlock does build Aghanim's Scepter and 
Refresher Orb, the physical damage from Golems will overwhelm Marci, especially when played as a support.
Clinkz
* Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.
Clinkz
* 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.
Clinkz
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, Bounty Hunter.
Clinkz
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Clinkz
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to 
Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Clinkz
* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz, 
Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and 
Keeper of the Light.
Warlock
* 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.
Additional:
* Because Shadow Fiend lacks escaping mechanisms, and is dependent on fair positioning for channeling 
Requiem of Souls, it's easier for Warlock with his long range crowd control abilities to lock Shadow Fiend down for his team.
Clinkz
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: 
Ember Spirit, Riki, Clinkz, Queen of Pain.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Clinkz
* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a 
Supernova, perhaps even while debuffed by Fire Spirits: 
Juggernaut, Clinkz, Troll Warlord, Beastmaster, Lina.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Clinkz
* Heroes that can pick you off: Clinkz, Nyx Assassin, Puck, Riki.
Warlock
* Chaotic Offering can stop heroes who like to use spell immunity and teleport scrolls to safely farm during the early to mid game, since it stuns and also goes through spell immunity. Notable examples: Juggernaut, Lifestealer.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Clinkz
* 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.
Warlock
* 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.
Clinkz
* With Bloodthorn, Clinkz becomes a strong counter to heroes who rely on evasion and blind such as Windranger, Phantom Assassin, Troll Warlord and Keeper of the Light.
Clinkz
* Clinkz can use Burning Army in teamfights which will cause a problem for Alchemist.
Warlock
* 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.
Clinkz
* 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.
Clinkz
* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper, 
Venomancer, Clinkz.
Clinkz
* 
Untouchable prevents Clinkz from harassing Enchantress in lane by lowering his attack speed.
* 
Nature's Attendants helps Enchantress to sustain through Clinkz's harassment in lane.
Warlock
* 
Enchant can not control golem Chaotic Offering from Warlock.
Warlock
* Warlock's signature Chaotic Offering can be devastating if stolen and dropped on multiple heroes.
* Telekinesis interrupts Upheaval when used on Warlock. Alternatively, Rubick can also cast this on a naerby creep or hero and drop them near Warlock to interrupt its channeling. When upgraded with Aghanim's Shard, Rubick can also use it to save an ally (or himself) from its area slow and damage.
* Fatal Bonds provides Rubick with a decent farming and harassing tool in the early game.
* Shadow Word provides some utility by healing Rubick and his team, and also as a harassment tool when used on enemies in the laning stage.
* Upheaval slows and damages enemies in an area, and it works exactly the same when casted by Rubick. Furthermore, he can extend its range and debuff amplification with Arcane Supremacy.
* A stolen Chaotic Offering can also be used to interrupt Upheaval while Telekinesis is on cooldown.
* It is advised to build items around Chaotic Offering as Rubick. Aghanim's Scepter, 
Octarine Core and Refresher Orb are all legitimate item choices.
Additional:
* All of Warlock's abilities are worthy choices for Rubick to 
Spell Steal, primarily Chaotic Offering. Furthermore, stolen abilities are also affected by the increased cast range and spell amplification from 
Arcane Supremacy.
* 
Telekinesis interrupts Upheaval when casted on Warlock, or to save allies (or himself) from its area slow and damage with Aghanim's Shard.
* Bear in mind that Warlock likes to cast his abilities in quick succession, so the time window left for Rubick to steal Warlock's ultimate can be short.
Clinkz
* Considering Rubick's abysmal armor, Rubick is a squishy target for Clinkz to gank on his own.
* None of his spells are useful except for Skeleton Walk.
* Clinkz usually builds Orchid Malevolence, which disables Rubick's ability to retaliate.
* Vast numbers of 
Sentry Wards are needed to deal with Clinkz because of Skeleton Walk, making it harder for Rubick to buy more expensive and more useful support items like 
Glimmer Cape or 
Mekansm.
Warlock
* Ghostship helps your team soak up damage from Chaotic Offering and hit summons hard.
* Tidebringer clears summons later in the game.
* Most of your spells can interrupt Upheaval.
Clinkz
* Clinkz's high damage output and insane attack speed late-game can take Kunkka out of the fight before it begins.
* Burning Barrage and Searing Arrows together can kill allies easily even under Ghostship's buff.
