* Phoenix turns night to day, overriding Dark Ascension during Supernova.

* Sand King and Phoenix have many tools to deal with multiple enemies at once, which will work well against a crowd of illusions.

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

* Rubick usually positions in the back of a team. Heroes who can sneak up and assault Rubick (e.g. Slark) or damage Rubick from great distance (e.g. Spectre, Sniper) should be treated cautiously, as otherwise the matchup usually ends up badly for Rubick.

* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.

* Rubick usually positions in the back of a team. Heroes who can sneak up and assault Rubick (e.g. Slark) or damage Rubick from great distance (e.g. Spectre, Sniper) should be treated cautiously, as otherwise the matchup usually ends up badly for Rubick.

* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.

* If Rubick can use Spell Steal to steal Holy Persuasion, he will be able to turn Chen's creeps against him, reducing much of Chen's efficiency.
* Rubick can also steal Hand of God and use it to save his teammates during teamfights and Penitence to slow down Chen and make Rubick and his allies attack him faster.
* Telekinesis can be used to coordinate gank on Chen and prevent him from escaping.
* Fade Bolt can deal high damage to both, Chen and his creeps and weaken their damage output.

* Phoenix's large damage over time with Icarus Dive and Fire Spirits can kill Chen's allies before he can use Hand of God.
* Phoenix naturally buys Spirit Vessel, which allows him to reduce healing from Divine Favor and Hand of God.
* Phoenix's Supernova cannot be damaged by Chen's creeps, and their normal speed means they will often not be able to kill Phoenix whenever he uses Supernova.
Additional:
* Not only Phoenix is able to disrupt Chen's jungling with Fire Spirits, but its high damage over time can also force Chen to use Hand of God prematurely, potentially wasting any chance to save his allies during teamfights.
* Creeps' damage and attack speed are very abysmal, so Chen often cannot kill Phoenix whenever it casts Supernova.

* 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.
Additional:
* Reverse Polarity, if stolen, can counter-initiate Magnus's team and put them at a huge disadvantage.
* Magnus himself is positioned at the center of teamfight after casting Reverse Polarity, and will be stunned by Rubick's stolen one most of the times.
* Bear in mind that Magnus will usually cass Skewer or Shockwave after he casts the ultimate, so the time windows left for steal can be short.
* Shockwave allows Rubick to farm fast, and also deals decent AoE damage in teamfights.
* Empower can be casted on the carry (especially affective if melee) on Rubick's team to accelerate their farm or amplify their damage in fights.
* Skewer could be used to displace enemy or escape from danger.
* Telekinesis can relocate the enemy in front of Rubick for Skewer.
* With Quick Cast enabled, Rubick can stop the enemy Magnus with careful prediction using Telekinesis to interrupt Horn Toss - Skewer combo.

* Phoenix will usually be on the sidelines or further back ready to use Sun Ray. Even after Magnus successfully uses Reverse Polarity and skewer Phoenix's teammates, Phoenix can usually counter-initiate using all of its abilities.

* Rubick can cancel Spirit Breaker's Charge of Darkness with Telekinesis under the condition that Rubick is able to cast it on time. And considering Rubick commonly buys Eul's Scepter of Divinity that can also cancel Charge of Darkness, Spirit Breaker will have a hard time charging Rubick or his allies until Spirit Breaker buys Shadow Blade. Telekinesis can also be used to cancel Nether Strike and Aghanim's Shard upgraded Telekinesis also allows Rubick to save his allies from Spirit Breaker.
* Fade Bolt weakens Spirit Breaker's damage output, reducing damage of Greater Bash.
* If Rubick succeeds to steal Charge of Darkness, he will be able to reduce much of Spirit Breaker's global presence. Rubick can also steal Nether Strike to further disable Spirit Breaker once he disables him with stolen Charge of Darkness. But bear in mind, however, that a skilled Spirit Breaker can use Bulldoze to prevent all that.

* Due to Spirit Breaker's low attack speed, Supernova is problematic for Spirit Breaker to take down, and even more so with Fire Spirits debuff applied.

* Rubick can steal abilities from Kunkka (except Tidebringer) with Spell Steal. Since build Aghanim's Scepter, Rubick's make two steal abilities from Kunkka when the spot is right.
Additional:
* Kunkka is a strong teamfighter with his powerful control spells, which Rubick could exploit to his advantage.
* Torrent provides another source of damage and crowd control.
* Ghostship is a powerful teamfight spell, providing huge magical damage to enemies and buffing allies with damage negation.
* Both skills works the best when comboed with other source of control from allies, such as Duel or Beserker's Call.
* Telekinesis can reposition an enemy onto a Torrent or Ghostship.
* Torrent Storm works as a disruptive spell for Rubick to create chaos around him.
* Tidal Wave offers another source of control and repositioning.
* As long as Kunkka gains these spells with Aghanim's Shard and Aghanim's Scepter, Rubick does not need extra items to steal these spells.
* X Marks the Spot serves as a utility spell for escaping, chasing and other useful functions.

* Supernova negates Kunkka's combo entirely, as it can't be affected by spells while using Supernova.
* Icarus Dive also allows Phoenix to dodge Ghostship and Torrent.

* 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.

* Sand King has nothing to deal with Supernova, as none of his spells are effective.
* The damage-over-time abilities of Phoenix disable Sand King's Blink Dagger very often.

* Crystal Nova helps on farming while applies an area slow.
* Frostbite extends Rubick's lockdown duration while providing extra damage, also serves as a farming ability.
* Freezing Field deals much greater damage thanks to Arcane Supremacy in teamfights.
* Freezing Field is a channeling ability and therefore can be stolen easily.
* Crystal Maiden has no innate ability to interrupt Freezing Field, though it may not be the case for her teammates; Yet a well-times Telekinesis lift or drop can interrupt Freezing Field.
* Consider build items that strengthens Freezing Field, such as Aghanim's Shard, Black King Bar and Aghanim's Scepter to reach its full potential.

* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.

* Shadow Fiend's Requiem of Souls allows Rubick to output enormous crowd damage and control to the enemy team.
* Requiem of Souls has an effective range of 1000. Rubick can steal the spell out of the fear range with any level of Arcane Supremacy learned.
* Requiem of Souls has a significant cast animation which allows Rubick to predict the steal timing, since Shadow Fiend usually positions at the center of battlefield.
* Telekinesis can lift a unit right on top of Rubick with no collision size, forcing the victim to absorb all damaging lines of Requiem of Souls from Rubick, possibly resulting in a one-shot kill.
* Note that Requiem of Souls from Rubick still uses the original 1.67 second channeling time.
* It is advised to build Blink Dagger to jump in and cast Requiem of Souls given the opportunity.
* The three Shadowraze (Far) abilities are decent for farming and extra damage output.
* Note that Shadowraze (Near), Shadowraze (Medium) and Shadowraze (Far) are considered three separated abilities, only one is stolen per spell steal cast.
* It could be troublesome to cast Shadowraze (Far) immediately for damage output immediately after stolen since it is hard to react and recognize which of the three is stolen.
* Shadow Fiend's right click damage together with his ability damage may hurt Rubick bad. Consider items like Ghost Scepter and Glimmer Cape, together with wards to avoid being picked up.

* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.

* Meat Hook can prove annoying for Pudge if Rubick Spell Steals it, allowing Rubick to easily hook and save his allies being Dismembered.

* Heroes with high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.

* Witch Doctor's iconic Death Ward is a perfect spell for Rubick to output high damage.
* Death Ward requires channeling which makes Witch Doctor a clear tagret for stealing. Rubick can steal the spell outside of Death Ward's attack range most of the times.
* Note that an skilled Witch Doctor player can cast Voodoo Restoration to disrupt their last spell for Rubick to steal.
* Telekinesis can interrupt a channeling Death Ward. With Death Ward's high burst damage, combining Death Ward and Telekinesis to hold enemy in place can result in a solo kill in the early game.
* Paralyzing Cask provides an additional disable. The ability also helps moderately with farming.
* Voodoo Restoration provides some utility by healing Rubick and his team.
* Maledict is a damage-over-time nuke that amplifies the damage enemy taken.
* Telekinesis can reposition the enemy within the range of Maledict.
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.

* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.

* 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.
Additional:
* Morphling's abilities can grant unrivaled utility for Rubick.
* Attribute Shift (Strength Gain) is a great spell that has a longlasting effect, since the attribute change is permanent even after losing the ability. By casting the spell, Rubick becomes significantly tanky after pumping all his agility into strength.
* As the cost of the shift, Rubick's attack speed as well as his armor is hindered. Since the right click damage of Rubick is relatively trival in teamfights, armor items such as Medallion of Courage or Buckler could greatly increase Rubick's effective health to physical damage.
* Rubick must be careful not to confuse Attribute Shift (Strength Gain) with Attribute Shift (Agility Gain).
* Adaptive Strike (Strength) is a long-ranged stun.
* If Attribute Shift (Strength Gain) has been stolen and cast, the spell can stun the enemy for 3 seconds. The stun counters mobile heroes such as Morphling.
* Waveform is a damaging pseudo-blink, giving Rubick much needed mobility and farming potential.

* Phoenix's AoE abilities can prove troublesome for Phantom Lancer.
* Fire Spirits dramatically reduces Phantom Lancer and his illusions' attack speed.
* Icarus Dive's movement speed reduction makes retreating difficult.
* Supernova burns away illusions, and is invulnerable to attacks from illusions.

* Venomous Gale is a great ganking and farming skill.
* Plague Ward serves as a flexible ability for pushing, ganking, farming and scouting. The innate Poison Sting also works on the stolen Plague Ward with half the damage.
* Poison Nova, if stolen and cast, puts a huge damage-over-time debuff on the enemy team, even greater than Venomancer himself with the help of Arcane Supremacy.
* Spell Steal has a greater cast distance than the effect area of Poison Nova, allowing Rubick to steal the spell while staying at the back.
* Venomancer suffers from mana pool problems, while Rubick has relatively high intelligence gain and can cast the same set of spells at ease.
Additional:
* All of Venomancer's abilities are decent choices for Rubick's Spell Steal. Stealing Plague Wards makes them apply Poison Sting as well.

* Shield Crash is a great area-of-effect ability on Rubick primarily for farming.
* Swashbuckle is a great reposition and damage ability on the hands of Rubick.
* Note that Rubick does not have Lucky Shot, so the ability might be less effective as a source of damage.
* Pangolier may build items such as Maelstrom or Diffusal Blade to add up attack multipliers to the ability, and Rubick can choose to build similar items should he choose the route.
* Rolling Thunder is a unique ability that allows Rubick to jump in the center of teamfight while protected by Spell Immunity, creating chaos and possibly chain stun the enemy team.
* Rolling Thunder negates the collision damage and stun from Pangolier's Rolling Thunder.
* Rubick uses the fixed 0.15 second cast time when casting Rolling Thunder, making it faster than Pangolier himself.
* Rubick can still use his abilities during Rolling Thunder - throwing an enemy en route by casting Telekinesis can be a good idea.
* The decision to steal Rolling Thunder should be made quickly as Pangolier cast Shield Crash very often during Rolling Thunder.

* Her Refraction charges can and will be easily burned away by Phoenix's damage over time abilities, and Meld can't protect her from Phoenix's AoE abilities, even without detection.
Additional:
* Phoenix's abilities target and deals damage over time, making them a threat against Meld and Refraction. His abilities' nature makes them pretty hard to correctly land on the target, but that is not a problem against a Templar Assassin that needs to stand still during Meld.
* Icarus Dive allows Phoenix to shrug off the slow from her trap and make an easy escape from her ambush.
* As Templar Assassin relies on her quality-over-quantity bursting attacks to make quick work on fragile target, Fire Spirits' attack speed reduction can cripple her ability to deals any damage during combat. With the debuff applied in early-mid game, a Meld-breaking hit from her is significantly slowed to the point that her target can travel a safe distance before she even lands the hit.
* Sun Ray has a quick damage tick and will burn through her Refraction in no time.
* Supernova deals damage over time in an incredibly large area, and again with her quality-over-quantity style, she may not be able to attack quickly enough to break through the Phoenix Sun by herself. (not to mention the debuff from Fire Spirits) This can lead to a failed ganking attempt or even a turnaround.

* Stroke of Fate provides Rubick with a short cooldown nuke.
* Note that Rubick uses a fixed 0.15 second cast time for the skill, much shorter than the 0.6 second cast time for Grimstroke.
* Phantom's Embrace is an unique ability with extra silence and damage.
* Ink Swell is a great initiation/counter-initiation ability for frontliners.
* With Telekinesis, Rubick can grant extra duration for Phantom's Embrace's phantom latch, or throw an enemy within the area covered by Ink Swell.
* Soulbind, as a powerful ultimate, gives Rubick extra crowd control and sows chaos among enemies.
* Both Telekinesis and Fade Bolt are single-target abilities, and can be applied twice on the enemy. The damage of Fade Bolt is effectively doubled as the bounce is very likely to happen as the bound heroes must walk together.

* In the mid to late game, the physical attack from Sniper can be painful to go through as Rubick. However with the help of Rubick's teammates, the abilities of Sniper can turn against his team.
* Shrapnel is a great wave-clear ability, and helps with scouting the area.
* Shrapnel already has a long cast range, and together with Arcane Supremacy Rubick can put constant damage on Sniper while he stays at back.
* Assassinate, if stolen, can be cast to assist a gank while Rubick stays at a range that can merely be found in the area, damaging heroes in the backline including Sniper.
* Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to 406.2/611.1/819(531.2/805.1/1079) without considering any further amplification source.
* With Aghanim's Scepter, Assassinate becomes an ability with a reliable 1.5 second stun, massive damage, short cooldown and over 3000 cast range which should not be made light of.
* Shrapnel is used frequently and can be easily stolen; Assassinate has a long cast animation for Rubick to forsee the chance to steal.

* All of Lion's abilities are dangerous even to Lion himself, and Rubick may steal them with Spell Steal.
* Arcane Supremacy powers up abilities cast range and damage, making Rubick better at using Lion's abilities than Lion himself.
* Telekinesis can easily catch and disable Lion while also manipulating his position to favor Rubick and allies, rendering him helpless.
Additional:
* Earth Spike is a great crowd control ability for Rubick to use, extending his lockdown potential.
* Rubick can caught enemy at greater distance due to Arcane Supremacy.
* The spell also helps with Rubick's farming, however the affected area of Earth Spike is limited to a straight line, making it harder to clear the creep wave.
* Hex is one of the strongest single-target lockdowns in the game, and works exactly the same when casted by Rubick.
* Though Mana Drain does not directly provide damage or lockdown, it does solve Rubick's mana regen issue in the early to mid game.
* Finger of Death is one of the best magical nukes in the game, increases Rubick's ganking potential greatly.
* Note that the stack of Finger of Death is lost when Rubick lost the spell.
* With Aghanim's Scepter, Rubick can clear creep waves and flash farm with the boosted Finger of Death if stolen, assuming Rubick has enough mana pool to hold.

* Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. Shiva's Guard, Heaven's Halberd and Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while Spirit Vessel's percentage-based damage is good against his innate durability.

* Telekinesis allows Rubick and his team to coordinate a gank on Luna early on. And just like Aghanim's Shard upgraded Dismember, Aghanim's Shard upgraded Telekinesis can also allow Rubick to save an allied hero from being killed by Eclipse.
* Fade Bolt allows Rubick to harass Luna on lane and weaken her attack damage early on.
* Both, Lucent Beam and Eclipse are very useful for Rubick to steal with Spell Steal, Luna's only way to counter this is with Aghanim's Shard upgraded Moon Glaives. Rubick can also use them from further distances than Luna thanks to Arcane Supremacy that increases his cast range and when he gets Aghanim's Scepter.
* For the same reasons, Rubick makes a very powerful ally for Luna when they are in the same team.
Additional:
* Lucent Beam is a solid magic nuke with a stun.
* Aghanim's Shard upgraded Lucent Beam gives Rubick bonus damage whenever he uses it
* Eclipse can output massive damage if casted by Rubick.
* Rubick has a good chance to steal Eclipse since Luna has only two cast abilities.
* Aghanim's Scepter greatly increase the effectiveness of the ability, with more damage as well as extended cast range.
* For the same reasons, Rubick also makes a good ally for Luna when they are in the same team.

* Primal Beast is disarmed during Trample so will be unable to destroy a Supernova no matter how close it is to him.
* The same ability can also be used to save allies with the help of an Aghanim's Scepter.
* Sun Ray will do thousands of damage to Primal Beast if surviving a full channel time due to his high health scaling for the ability.
* Icarus Dive is a fantastic way to escape Primal Beast after he has used Onslaught.
* Phoenix has a naturally very high health pool making it hard for Primal Beast to deal with him with his magical damage.

* All of Queen of Pain's abilities are worthy choices for Rubick to Spell Steal. In addition, he can cast her abilities from further distances than her thanks to Arcane Supremacy's increased cast range and spell amplification.

* 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.
Additional:
* One of Jakiro's weakness is his long cast animation, which gives enemy team extra time window to react. Rubick uses his fixed 0.15 second cast time for all Jakiro's stolen abilities, making the spells much easier to target.
* Dual Breath is a solid damage-over-time that is good for farming and helps with ganking.
* Ice Path is the go-to spell for Rubick to steal in teamfights - a sudden long range 2.5 second area stun is of no joke, especially if being casted out of vision. The control time is extended combined with Telekinesis.
* Macropyre is a solid damage source (an area to avoid at least) for Rubick's side, and the damage benefits from Arcane Supremacy, even further with Aghanim's Scepter.
* It is not uncommon that the enemy team mistakenly treated the Macropyre ground effect as that of Jakiro's, and has already taken a lot of damage before they noticed their significant HP loss.
* Combined with Rubick's Level 15 talent (-25% Stolen Spells Cooldown, as of 7.31c), Macropyre can be used to clear creep waves and camps with ease, increasing his farming progress if a fight is not imminent.

* Supernova allows Phoenix to save himself (or an ally, with Aghanim's Scepter) through Echo Slam. Earthshaker will also have a difficult time destroying the supernova, due to his low base attack time and poor agility.
* Icarus Dive can pass through Earthshaker's Fissure.
* Most of Phoenix's abilities disable Earthshaker's Blink Dagger for a good period of time due to the damage-over-time nature of its spells.

* Icarus Dive quickly escapes from Shadow Demon abilities, especially Demonic Purge.
* Phoenix AoE abilities remove Shadow Demon's illusions created by Disruption.

* 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.

* Clockwerk being confined in his own Power Cogs means Clockwerk is unable to quickly escape from Phoenix's Sun Ray and Supernova.
* Sun Ray will also heal the enemy Clockwerk is fighting, making it unlikely for Clockwerk to take an enemy down with him.
* For the same reasons, Phoenix also makes a powerful ally for Clockwerk when the situation is reversed.

* 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 hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.

* 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.
Additional:
* Enigma's signature Black Hole can be devastating if being stolen and dropped on multiple heroes.
* Black Hole requires channeling. Since Enigma has no other ability to replace his last casted spell during channeling, Rubick can steal Black Hole relatively easily if he stays back.
* Rubick can interrupt Black Hole from Enigma, even with an activated Black King Bar, by casting the spell with Enigma in range with regards to the extra cast range granted by Arcane Supremacy.
* Black Hole can be interrupted by Telekinesis in the early game, giving enough time window to steal the spell.
* Bear in mind that an experienced Enigma will purchase Black King Bar and Linken's Sphere at the same time to prevent Rubick from stealing the spell, yet the extra Linken's Sphere will delay Enigma's power spike, so use it to Rubick's advantage.
* It is advised to build items around Black Hole as Rubick. Aghanim's Shard, Black King Bar , Aghanim's Scepter and even Refresher Orb are all legitimate item choices.
* Malefice is a decent source of damage and stun that helps with ganking. If stolen, it can be used to interrupt Black Hole as well.
* Demonic Conversion helpes with pushing and farming for Rubick.
* Fade Bolt effectively negates damage from Eidolons and helps with counter-pushing.
* Midnight Pulse is a solid skill for farming and teamfight damage, which is further amplified by Arcane Supremacy and talents.
* Unexpected enemy may take the effect of Midnight Pulse as that of Enigma's and soak up damage while unrealized.

* Tombstone can be stolen to counter-initiate the enemy team in skirmishes.
* Tombstone provides vision over the enemy around, use this to Rubick's advantage for more spells.
* Since Undying is melee and has low attack speed, the tombstone can be hard to taken down by Undying himself.
* Flesh Golem provides Rubick with increased Health pool and a powerful attack modifier.
* Rubick can apply the Flesh Golem debuff much more easily as a ranged hero.
* Decay is a decent damaging ability, making Rubick somewhat tankier in teamfights.
* Soul Rip can be used for extra heal or burst damage.
Additional:
* All abilities from Undying easy to steal to Rubick with Spell Steal.

* 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.

* Spell Steal will easily steal all abilities from Dark Seer.
Additional:
* Spell Steal can perfect from Rubick's steal all abilities from Dark Seer. Rubick's always purchase Aghanim's Scepter can two stolens abilities from Dark Seer's and waiting for seconds for second stolen abilities (example: combinated Vacuum and Wall of Replica) and many different combination.
* A good positoning from Rubick's Spell Steal waiting steal abilities from Dark Seer Wall of Replica and illusion from Wall of Replica Dark Seer's can fighting with effect from outcome steal Wall of Replica from Rubick's.
* Combinated Rubick's steal Surge and Blink Dagger is very important catch from Dark Seer's and enemies.
* Rubick's Telekinesis can lifted up Dark Seer or enemy heroes and throw to Wall of Replica from Rubick's steal.

* 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.

* Ether Shock is a great farming ability as a handy short-cooldown nuke.
* Hex and Shackles gives Rubick extra lockdown potential in ganks and teamfights.
* Mass Serpent Ward, should Rubick steal, serves as a powerful source for teamfighting, pushing, and acquring Roshan.
* Arcane Supremacy allows Rubick to cast Hex and Shackles at a further distance, which keeps Rubick at a safer position compared to Shadow Shaman.
* Rubick can interrupt Shackles by casting Telekinesis.
Additional:
* All abilities from Shadow Shaman can very vulnearble steal from Spell Steal.
* Rubick can interrupt Shackles by casting Telekinesis.

* Magic Missile is a solid damage source and lockdown that fits nicely with Rubick's kit.
* Rubick also acquires the secondary Magic Missile with Aghanim's Shard.
* Wave of Terror can be used to scout an area to prevent juking or initiate with Telekinesis, as well as reducing the armor of enemy team during a teamfight.
* Nether Swap does what it does - saving an ally from danger, initiating on an enemy, or helping with caughting a fleeing hero.
* With Aghanim's Shard, Rubick can lift himself up and drop quickly to a place of safety after the swap. Note that Rubick can only choose to either disable the enemy or save himself at one time with Telekinesis.
Additional:
* 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.

* Lone druid's bear attacks on Phoenix's Supernova Egg don't increase the hit count. Given that Lone Druid's main hero often doesn't have much farm, the Supernova Egg is less likely to get killed.

* Sun Ray allows Phoenix to heal any allies caught in Berserker's Call while burning away Axe's high HP at the same time.
* Icarus Dive and Fire Spirits puts Axe's Blink Dagger on cooldown.
* Axe's slow attack speed makes it difficult for him to destroy Supernova on his own.

* As a frontline tank, the abilities of Underlord is surprisingly spell-cast heavy, and is often great for Rubick to steal.
* Firestorm is a great ability for farming, pushing and serves as a useful teamfight damage source, and even more so when its damage is amplified by Arcane Supremacy and Aghanim's Shard.
* It is worth mention that Firestorm has no visible effect on heroes other than damage, and the enemy team may easily mistaken the ability as casted by Underlord, resulting in unexpectedly soaking up more damage.
* Pit of Malice is a great area control ability in teamfights, capable of trapping multiple heroes in a hazard area.
* Underlord has no immediate reposition ability, and since he usually stays at the front, he can be an easy target for Rubick's Pit of Malice.
* Fiend's Gate, if stolen, grants Rubick's team great versatility around the map. Creating a surprise gank or appear as a group at the enemy backline during skirmish, escaping as a team from bad situations, or even taking Roshan or enemy highground unexpectedly, the possibility are endless with careful communication among Rubick's team.
Additional:
* All of Underlord's abilities are useful for Rubick to Spell Steal.

* Phoenix's Supernova cannot be damaged by Familiars.
* In the early and mid game, Sun Ray won't deal enough damage to be reduced by Gravekeeper's Cloak.
* Once Sun Ray deals enough damage to protect Visage, a layer of Gravekeeper's Cloak is burnt every 0.2 seconds.

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

* 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 high health especially Strength heroes will take more damage on Sun Ray: Axe, Pudge, Bristleback, Mars.

* Heroes with strong area damage to destroy Phantasm illusions: Axe, Ember Spirit, Legion Commander, Phoenix

* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.

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

* Phoenix with Supernova
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova

* Icarus Dive and Supernova can destroy the tree Monkey King is standing on.
* Fire Spirits reduces Monkey King's attack speed, preventing Monkey King from building up Jingu Mastery.
* Supernova can be casted next to Wukong's Command, forcing Monkey King to step away of it or to withstand its massive AOE damage
Additional:
* Icarus Dive, Sun Ray, and Supernova all destroy trees that Monkey King relies on to use his ability Tree Dance. If you spot him, you can quickly Icarus Dive in his direction and then follow up with Fire Spirits and Supernova. If you manage to cut the tree he is on, he will be stunned for 4 seconds and will be forced to take a lot of damage. However, most Monkey King players tend to build attack speed items to make use of their passive, Jingu Mastery, so a battle against a farmed Monkey King will depend on who gets the jump on the other first.

* Icarus Dive helps Phoenix escape from Cold Feet.
* However, all of Pheonix's basic abilities do cost health, which can be harmful under the effects of Ice Blast.
* Supernova can save Phoenix from Ice Blast.
Additional:
* Supernova with or without Aghanim's Scepter allows to save ally or himself through Ice Blast.
* Icarus Dive quickly escapes from Cold Feet.

* Dragon Slave is easy to steal, and provides Rubick with a useful nuke.
* Light Strike Array serves as a cheap nuke as well as a crowd control ability.
* Rubick uses the fixed 0.15 second cast time when casting Light Strike Array, much faster than Lina herself.
* Rubick can gurantee a stun by throwing the victim into the area with Telekinesis, extending the overall lockdown duration.
* Laguna Blade is an awesome ultimate that gives huge burst damage.
* Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to a whopping 660/882/1134(830/1162/1494) (and even more so with Aghanim's Scepter), without considering spell amplification from items.
* Laguna Blade is an intelligence hero with no regen ability, and casting Laguna Blade back to Lina can result in her unexpected sudden death, or severly hinder her presence in the rest of teamfight. Nevertheless, the skill can also be cast on other squishy heroes or help bursting down enemy carries.
* Light Strike Array and Laguna Blade has a short cast range, and Rubick can extend its range thanks to Arcane Supremacy.

* All of Puck's abilities are good for Rubick to Spell Steal:
* Illusory Orb and Waning Rift are all great wave-clear abilities.
* If Rubick manages to steal Waning Rift, he can silence Puck, disabling all its abilities including Phase Shift, Puck's main survivability tool.
* Dream Coil is a powerful teamfight ultimate that leashes enemies and disables their movement.
* As an elusive hero who requires constant repositioning, Puck is greatly countered by its own ultimate as it disables all its mobile abilities and items (especially Blink Dagger), forcing it to either stay in the danger zone or latches and stuns for a long time.
* Although Phase Shift does not provide extra damage or lockdown on its own, it does grant Rubick invulnerability, and enables him to use Blink Dagger with full duration similar to Puck's escaping combos.
* Rubick can initiate on Puck relatively fast as Telekinesis only has a 0.15 second cast animation.
Additional:
* Illusory Orb and Waning Rift are all great wave-clear abilities.
* Waning Rift can silence Puck, disabling all her abilities including Phase Shift.
* Dream Coil is a powerful teamfight ultimate that leashes enemies and disables their movement.

* Rubick can initiate on Puck relatively fast as Telekinesis only has a 0.15 second cast animation.

* Fire Spirits does damage over time, preventing Faceless Void from backtracking the full damage with Time Walk.
* Fire Spirits applies a big attack speed slow, stopping Faceless Void from doing many attacks while in Chronosphere.
* Sun Ray can heal allies and damage Faceless Void from outside Chronosphere.
* Supernova can be cast outside of Chronosphere, forcing Faceless Void to step away from it, lest he'll take a lot of damage

* 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.

* All abilities from Juggernaut (except Blade Dance) is very vulnearable steal to Rubick's Spell Steal.
Additional:
* Juggernaut looks like a carry that Rubick can hardly manfight, and it is surely the case that Rubick needs the assistance from his team to overwhelm the hero. However, his skills can be of great use for Rubick if used at the right occasions.
* Blade Fury is a great farming ability with low cooldown. What is bizarre about this ability is that it grants Rubick spell immunity and constant damage around him (movement speed buff with Aghanim's Shard). In early to mid game when all heroes has relatively low physical damage, the spell allows Rubick to become a temporary tank that enemy needs to run away from, extending Rubick's early killing potential.
* Telekinesis can throw a victim in range to eat up the damage from Blade Fury.
* Blade Fury can be stolen and used in a pinch to negate the damage from Blade Fury of Juggernaut. Note that with Aghanim's Shard Juggernaut can still deal damage to Rubick.
* Healing Ward, if stolen, serves as a magnificant healing tool within or after a teamfight. The constant area-of-effect healing helps greatly when your teammate is manfighting the enemy or escaping in a bad situation, and can even turn the fight around.
* Juggernaut is melee and cannot target an enemy Healing Ward easily unless he is in the midst of battle. Also, Juggernaut is not directly controllable during Omnislash and cannot attack Healing Ward.
* Omnislash is possibly the least useful spell Rubick can steal from Juggernaut. Although it is a good damage source in the early game, as a hero who seldom bulk up his physical damage, Omnislash falls quickly as the game goes on.
* It is worth mention that Omnislash could be used as an escape ability for Rubick with the help of Blink Dagger.
* Omnislash grants invulnerability at the midst of a fight. With quick reflex and judgement, Rubick can possibly dodge lockdowns and area disables, even steal a new spell when Omnislash is still on the fly.

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

* Fire Spirits applies a severe attack speed slow, severely hindering Phantom Assassin's damage output.
* Phantom Assassin cannot cast Phantom Strike on Phoenix during Supernova.
Additional:
* While her Phantom Strike does give limited extra attack speed, she cannot use the ability against the Phoenix Sun, and while her Blur may protect her from attacks, Phoenix's strong magical DPS burns away her small health pool quickly, and the attack speed slow makes her unable to fight back (provided she has no source of spell immunity).

* 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).

* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).

Additional:
* Legion Commander relies on her powerful attack and her Duel to be effective. But if Phoenix gets the jump on her first, she can find herself severely slowed, taking heavy damage, and find herself unable to Duel a burning Supernova.
* It must be noted that Press the Attack will both dispel the attack slow of Fire Spirits and grant her or whoever she targets bonus attack speed. This allows her to easily destroy a Supernova if caution is not taken to prevent this from occurring. As such, it would be a better decision to simply avoid a farmed or skilled Legion Commander instead of attempting to overpower her.
* If an ally is caught by Duel, Phoenix can use Sun Ray to heal the ally and damage Legion Commander, possibly swinging the Duel in their team's favor. Or with Aghanim's Scepter, Phoenix can save an ally from dying in Duel with Supernova and cancel the Duel as well.

* A hero that Rubick cannot reliably kill in most cases, Wraith King is deceptively vulnerable to Rubick in teamfights.
* Rubick can kite Wraith King by casting Telekinesis should Rubick stays alive after first wave of skirmishes.
* {{A:Fade Bolt|Rubick} negates damage from Wraith King's skeletons.
* Wraithfire Blast is a spell very easy to stolen even for new Rubick players if Wraith King is on the other side.
* A 2 second stun with a 8 second cooldown (6 second with Rubick's Level 15 talent -25% Stolen Spells Cooldown, as of 7.31c) is already far enough to lockdown Wraith King to a crawl, as he does not have much mobility on his own and can be easily targeted.
* Reincarnation may sound insurmountable, but the extra 3 second delay already grant about half the cooldown duration for a stolen Wraithfire Blast.
* Rubick has sufficient mana pool to cast Wraithfire Blast multiple times.
* Although not the best option, Vampiric Spirit can be casted after Rubick gained enough last hits to summon skeletons for pushing and farming.
