* 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.

* If Rubick can use Spell Steal to take Nethertoxin, he will be able to disable Corrosive Skin, reducing much of Viper's durability.
* He can also steal Viper Strike, which can be used to hinder a hero on your team (or multiple heroes, if Rubick has Aghanim's Scepter).

* 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 Searing Arrows.
* Clinkz often goes for a disabling item like Orchid Malevolence or Gleipnir, which allows him to cancel Enigma's Black Hole until Enigma gets Black King Bar.
* 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.

* Telekinesis has a longer range than the AoE of Black Hole for the purposes of cancelling it.
* All of Enigma's spells are useful to Spell Steal.
* Malefice is useful for interrupting channeling spells or long cast animations. Its stun duration is also amplified thanks to Spell Steal's debuff amplification.
* Demonic Conversion can be used to push or counter-push a lane.
* Midnight Pulse is useful to block an area or for team fights.
* Black Hole is very easy to steal, as it is a channeled ability. It's also one of the best ultimate abilities for team fights, and it can easily turn the fight around for the enemy team. It also does more damage and has a larger cast range thanks to Arcane Supremacy. A stolen Black Hole can also cancel Enigma's Black Hole.

* 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.

* All of Venomancer's abilities are decent choices for Rubick's Spell Steal. Stealing Plague Wards makes them apply Poison Sting as well.

* Heroes who can harass Omniknight out of lane will keep him weak in the mid game: Viper, Venomancer, Clinkz

* All of Omniknight's abilities are valuable for Rubick to Spell Steal, and Omniknight has no throwaway ability to cover his last used spell.

* 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.

* 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.
* Skeleton Walk can allow Clinkz to make a quick escape after Kunkka's combo, or even avoid it all together.

* Rubick can steal Death Ward easily as it is a channeled ability and then use it to turn teamfight to his advantage.
* However, a skilled Witch Doctor will toggle Voodoo Restoration immediately after placing his Death Ward to prevent that.

* 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.

* If Rubick steals Reaper's Scythe, he can turn the powerful ultimate back against Necrophos's team. Even his other spells are useful in Rubick's hands, giving him a sustain or a weak initiation/protection tool.

* Ember Spirit's Flame Guard provides no protection against Clinkz's physical damage output.
* Ember Spirit's low armor and health make him easy to kill quickly if a teammate can hold him down.
* If Clinkz has farmed an item that can disable, he can sneak up to and hunt down Ember Spirit while he farms or split pushes alone.

* 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.

* Searing Arrows makes Clinkz one of the hardest heroes for Clockwerk to lane against.

* Rubick can use Spell Steal to steal Astral Imprisonment, and if Rubick gets Aghanim's Scepter he gets 2 charges of it. This can overpower Outworld Destroyer in team fights.
* Rubick can also steal Sanity's Eclipse against Outworld Destroyer's teammates.

* Fade Bolt can hinder Jakiro's early pushing power by clearing creep waves.
* All of Jakiro's spells are great for Rubick to Spell Steal.
* Ice Path is a great spell for Rubick so steal, since Rubick has no cast time on stolen abilities, making Rubick's version of Ice Path much more reliable than Jakiro's.
* Macropyre is a great way for Rubick to farm.

* All of Vengeful Spirit abilities are very good for Rubick to Spell Steal:
* Magic Missile provides an additional nuke/disable to pair with Fade Bolt and Telekinesis, respectively.
* Wave of Terror serves as a good scouting/armor reduction skill that Rubick and his team can benefit from.
* Nether Swap complements Rubick's mobility and pairs well with other mobility items he usually builds. He can also use it to save an ally from danger.

* All of Magnus's spells are perfect for Rubick to steal, especially Reverse Polarity for a counter-initiation.
* Telekinesis is one of the best instant-disables in the game, completely ruining Magnus's initiation.

* All of Underlord's abilities are useful for Rubick to Spell Steal.

* 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.

* Burning Barrage and Searing Arrows 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. And if Clinkz has it, he will be able to silence Io and prevent him from escaping wit either Tether or Relocate.

* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, Bounty Hunter.

* Clinkz can use Burning Army in teamfights which will cause a problem for Alchemist.

* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).

* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* 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.

* 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.

* Heroes that can pick you off: Clinkz, Nyx Assassin, Puck, Riki.

* 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.

* 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.

* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit

* Heroes that can instantly kill creeps greatly reduce the effectiveness of Chen's converted army: Lifestealer, Doom, Mirana, 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.

* Burrowstrike is one of the best and easiest steals for Rubick and Sand King should be careful when playing against him - it's much better to give away Sand Storm.

* Fade Bolt reduces damage output of Anchor Smash.
* Ravage is an easy target to Spell Steal, so always be sure to use Anchor Smash immediately after Ravage when playing against a Rubick.
* Spells stolen by Rubick are potentially stronger due to the lack of cast animations, his talents, and his passive, Arcane Supremacy.

* Fiend's Grip is a powerful but channeled ability, making it useful and easy to Spell Steal and interrupt with Telekinesis.
* Stolen Fiend's Grip or Nightmare combined with Arcane Supremacy allows Rubick to disable Bane's allies for a longer period of time.
* As a natural Aghanim's Scepter carrier, Rubick can steal an upgraded Fiend's Grip and deal lots of damage to Bane's allies.

* Rubick is a potential counter to Bounty Hunter as he can steal his Track and use it against his invisibility, and also provide his team with more gold if the tracked hero is killed.

* Rubick's ability to steal Attribute Shift (Strength Gain) makes him extremely annoying to deal with because Rubick's shifted attributes will remain even if he steals a new spell.
* If Rubick moves enough points to strength and then steals Adaptive Strike, he will have a powerful 3-second ranged stun in his arsenal as well.
* Waveform provides a reliable nuke/escape to Rubick.
* Rubick can steal most abilities Morphling uses while Morphed, allowing Rubick to steal his own allies' abilities if the Morphling is not careful.

* All of Lion's abilities are worth stealing with Spell Steal.
* Arcane Supremacy makes the disabling spells stolen from Lion very useful, allowing you to disable enemies for an extremely long time during fights or ganks.
* By using Telekinesis, Rubick can easily catch Lion out. Without any escape mechanism, Lion is helpless, especially when ganked.

* 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.

* Heroes that reduce the damage that Marci can deal during her ultimate, like Razor, Rubick, Bane, Dragon Knight and Underlord.

* 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.

* All of Treant Protector's abilities are worth stealing, and Rubick is able to cast them with no animation time.
