* Rubick can turn around entire teamfights if he manages to steal Reverse Polarity.
* Shockwave allows Rubick to farm pretty fast together with Fade Bolt, and also deals decent AoE damage in teamfights.
* If Rubick steals Skewer, he can use Telekinesis to displace enemies and Skewer them away.
Additional:
* 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.

* 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.

* All of Winter Wyvern's spells are generally good for Rubick to steal:
* Arctic Burn provides bonus attack range, night vision and burn.
* Splinter Blast makes farming and pushing efficient while also slowing down the enemies.
* Cold Embrace can heal an ally and protect them against physical attacks.
* Winter's Curse can be stolen by Rubick and use it against herself or her own team.

* 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.

* 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 Devourer in team fights.
* Rubick can also steal Sanity's Eclipse against Outworld Devourer's teammates.

* Tinker's Laser is useful against Outworld Devourer, as the blind prevents him from landing Arcane Orbs.

* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina

* Spell Steal allows Rubick to claim Grimstroke's powerful abilities for his own, all of which are valuable.
* Arcane Supremacy increases the efficacy of stolen abilities.

* Fissure has a shorter cast time in Rubick's hands, making it a nice ability to either initiate or interrupt enemy ganks from a long distance.
* Though Echo Slam isn't as powerful for the lack of Aftershock on Rubick, the damage can still be massive on enemies.

* Tinker's March of the Machines will disable Blink Dagger over a large area.

* Everything Lion has is great in Rubick's kit, further amplified by Arcane Supremacy:
* Earth Spike adds a second bit of crowd control and some damage.
* Mana Drain solves a lot of Rubick's mana issues.
* Hex is one of the strongest single-target lockdowns in the game.
* Finger of Death is one of the best magical nukes in the game.
Additional:
* 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.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

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

* 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.

* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: Death Prophet, Sniper, Tinker, Windranger.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* Everything she has is great in Rubick's kit:
* Crystal Nova deals crowd damage and slows enemies, also helps on farming.
* Frostbite helps Rubick locks down enemies, also is a decent farming ability.
* Freezing Field is a channeling ability and therefore can be stolen easily.
* Arcane Supremacy's Debuff Duration Amplification also benefits Crystal Nova and Frostbite greatly.

* Because of her need to get status items early to tank it up, Rubick can greatly reduce her damage early with Fade Bolt
* Her stationary nature and the slow cast time of her spells makes it easier for Rubick to steal Stone Gaze or Mystic Snake
* Aghanim's Scepter's Mystic Snake is often better used by Rubick than by Medusa

* Rubick will find all Lina's abilities useful:
* Dragon Slave provides a good way to clear creep waves and allows Rubick to deal tons of magical damage in teamfights.
* Light Strike Array gives Rubick a solid area stun, which is easy to set up right after Telekinesis.
* Laguna Blade gives Rubick a massive damage boost and great solo kill potential.

* 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.

* Every ability Witch Doctor has is useful when Rubick manages to steal any of them:
* Paralyzing Cask provides an additional disable apart from Telekinesis and also helps Rubick to farm.
* Voodoo Restoration provides utility by healing Rubick and his team, since he has no heal of his own.
* Maledict is a solid damage-over-time nuke, which can be devastating to the enemy team.
* And most importantly, Death Ward is one of the best teamfight spells in the game. It also requires channeling, which makes it easy for Rubick to steal. And when combined with Aghanim's Scepter, this can prove deadly to the enemy team.
* However, a skilled Witch Doctor will always toggle Voodoo Restoration while channeling Death Ward to prevent that.
Additional:
* 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.

* 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.
Additional:
* Morphling's abilities can cause unique interactions on their own:
* Waveform is a damaging pseudo-blink, giving Rubick much needed mobility.
* Attribute Shift (Strength Gain) is a great ability for Rubick:
* The changes done by it are permanent even after losing the ability. Pumping all the agility into strength makes him much tankier. The armor loss due to reduced agility can be mitigated by cheap items like Medallion of Courage or Solar Crest.
* The extra strength allows Rubick to survive Morphling's Ethereal Blade - Adaptive Strike (Agility) combo.
* Beware when using Attribute Shift (Agility Gain)! Unlike Morphling, Rubick does not gain damage from it, since agility is not his primary attribute.
* Adaptive Strike (Strength) is a long-ranged stun.
* The true power of this ability is revealed when Attribute Shift (Strength Gain) has been stolen previously: it gives a 4 second ranged stun every 10 seconds, which greatly counters heroes with mobility, such as Morphling himself.
* All of Rubick's abilities break Linken's Sphere, a core item for Morphling.

* 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).

* All his abilities is decent in Rubick's kit:
* Frost Blast allows Rubick to harass and constantly slow down enemies.
* Frost Shield increases Rubick's as well as his allies' and tower's survivability to physical attacks.
* A well-timed Chain Frost can be devastating to the enemy team.

* 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.

* Lucent Beam is a solid magic nuke.
* Eclipse can cause massive damage if cast in the right time.
* Rubick has a good chance to steal Eclipse for Luna has only two cast abilities.
* Aghanim's Scepter greatly increased the effectiveness of the ability, including more damage as well as longer cast range. In addition, it allows him to cast it on another hero so Rubick doesn't have to get close to the enemy team in teamfights.

* All of Omniknight's abilities are valuable for Rubick to Spell Steal, and Omniknight has no throwaway ability to cover his last used spell.
Additional:
* All Omniknight's abilities are perfect to steal:
* Purification can heal allies as well as damage enemies under the right circumstances. It is extremely useful since Rubick has no heal of his own.
* Heavenly Grace gives a strength bonus, status resistance, and health regeneration, which can help an ally or Rubick survive longer.
* Guardian Angel can turn the tide of battle by negating all physical damage, which is especially useful if the opposing team has physical attackers.

* All of Invoker's abilities scales with his level, thus Rubick possesses great potential in late game by owning any of Invoker's arsenal.
* Fade Bolt counters early push from Forge Spirit.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* 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.

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

* Fiend's Grip is a powerful channeled ability, making it easy and useful 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 long amount of time.
* As a natural Aghanim's Scepter carrier, Rubick can steal an upgraded Brain Sap and deal lots of damage to Bane's team.

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

* 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.

* 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.

* 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.

* Everything Enigma has is something Rubick will like:
* Malefice helps with interrupting channeling spells in case Telekinesis is off cooldown.
* Demonic Conversion helps with pushing or counter-pushing a lane.
* Midnight Pulse is great for blocking off areas or just doing steady damage in teamfights.
* Black Hole is one of the best spells for teamfights, and could easily turn a losing one around.
* Black Hole also requires channeling, making it an easy steal for Rubick because he usually stays back in a teamfight, making it hard to catch him with Black Hole.
* Telekinesis can break Enigma's Black Hole fairly easily.
* Fade Bolt counters early push strategy of Enigma's waves of Eidolons.
* Spell Steal pierces spell immunity, so Enigma can't prevent Rubick from stealing Black Hole by activating Black King Bar.
Additional:
* 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.
* 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.

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

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* 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.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.

* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.

* Heroes who rely on physical damage will suffer from Laser: Phantom Assassin, Wraith King, Huskar.

* 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.

* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, Brewmaster, Death Prophet, etc.

* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, Brewmaster, Death Prophet, etc.

* Heroes with strong team-fight abilities (especially ultimates) like Tidehunter, Brewmaster, Death Prophet, etc.

Additional:
* 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.

* Heroes who rely on abilities to deal damage (e.g. Timbersaw, Tinker) can fight a Razor even after Static Link.

* Despite most Kunkka players depending on their immense physical damage, his spells provide a lot of utility for Rubick:
* Torrent is very easy to land when paired with Telekinesis.
* X Marks the Spot can potentially be more effective in Rubick's hands due to his tendency to increase his cast range with his talents and items.
* Ghostship, paired with Telekinesis, allows Rubick to land it very easily without requiring Torrent or X Marks the Spot.

* 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 .

* 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.

* 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.

* 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.

* 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.

* 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.

* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, Phoenix, Alchemist, Earthshaker, Razor, Tinker, Leshrac, Queen of Pain
