* 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.

* Vengeful Spirit has two abilities to interrupt Death Ward, even through Black King Bar.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

* 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.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

Additional:
* Vengeful Spirit can interrupt Black Hole's channeling through Black King Bar by using Nether Swap from a safe distance.
* Vengeful Spirit's Level 25 Talent can make her Magic Missile pierce spell immunity, giving her another option to use in conjunction with Nether Swap to cancel Enigma's Black Hole channeling through Black King Bar and Linken's Sphere.

* 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.

* Nether Swap breaks one ally out of Soulbind, and can be used to redistribute the shared damage to Vengeful Spirit herself.

* 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 her Nether Swap, Vengeful Spirit can save the life of an ally who gets caught with Flaming Lasso. Nether Swap also makes it highly dangerous for Batrider to attempt a lasso, as it can lead to his own demise far behind enemy lines.
* Wave of Terror's flying vision allows Vengeful Spirit to spot Batrider trying to close in on his target with Firefly.
Additional:
* Nether Swap breaks Flaming Lasso when used on ally and can break if used on Batrider.
* Vengeful Spirit can disable Batrider's Blink Dagger before a fight with Wave of Terror.

* 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.

* 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.

* Nether Swap can forcibly reposition Sharpshooter.

* 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.

* Nether Swap gives Vengeful Spirit a way to save an ally from Clockwerk's Power Cogs.
* Magic Missile will interrupt Clockwerk trying to run down Vengeful Spirit's allies with Battery Assault.

* 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.

* 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.

* 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.

* 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.

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

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

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

* Huskar struggles against heroes that output high physical damage due to his low armor. Vengeful Spirit's Wave of Terror and Vengeance Aura help increase the physical damage of her team.

* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's Poof, preventing isolated Meepos from fleeing.

* 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.

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

* Heroes with disables that ignore spell immunity will render Phantom Assassin quite useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa.

* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer

* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

* She can easily cancel Wukong's Command with Nether Swap.
* Wave of Terror can also detect him while he's on the trees.
Additional:
* Wave of Terror grants flying vision over trees, and its wide effect can hit Monkey King and end Mischief.
* Nether Swap can easily cancel Wukong's Command by swapping him out of the circle.

* 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).

* With her Nether Swap, a well positioned Vengeful Spirit can save the life of a more important ally who gets caught in Chronosphere.
Additional:
* Nether Swap can save an ally from the Chronosphere.

* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.

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

* 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.
