Spectre
[wiki] rating: 2.0 (winrate: 50% pickrate: 4%)Naga Siren
[wiki] rating: 1.6 (winrate: 51% pickrate: 2%)Rubick
* Song of the Siren is very difficult for Rubick to 
Spell Steal when he is affected by sleep.
* Ensnare and Rip Tide together with some attacks can take Rubick down quickly, due to his low health pool and armor.
* Naga Siren usually buys 
Diffusal Blade, which may prevent Rubick from using his abilities.
* Mirror Image allows Naga Siren to dodge the incoming stun from 
Telekinesis (when she is not a target), and it can also dispel 
Fade Bolt's damage reduction debuff.
Bounty Hunter
* 
Naga Siren with 
Mirror Image
* Heroes that can remove the Track debuff with their skills:
* 
Abaddon with 
Aphotic Shield and 
Borrowed Time
* 
Huskar with 
Life Break
* 
Juggernaut with 
Blade Fury
* 
Legion Commander with 
Press the Attack
* 
Lifestealer with 
Rage and 
Infest
* Naga Siren with Mirror Image
* 
Omniknight with 
Heavenly Grace
* 
Oracle with 
Fortune's End and 
False Promise
* 
Phantom Lancer with 
Doppelganger
* 
Slark with 
Dark Pact
* 
Ursa with 
Enrage
* 
Weaver with 
Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Additional:
* Bounty Hunter is a single target damage dealer, so he will not fare well against Naga Siren. He may try to 
Track her, but her Mirror Image will dispel the effect. Ensnare also reveals invisible units while they're rooted, putting Bounty Hunter at a disadvantage.
Wraith King
[wiki] rating: 1.6 (winrate: 51% pickrate: 10%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and 
Wraith King to heroes with quick escape mechanisms like 
Anti-Mage and 
Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Rubick
* Wraith King abilities are mostly passive making Spell Steal meaningless.
* This can also mean that Rubick's Spell Steal used on Wraith King guarantees him a stun spell.
* Rubick's lack of mobility & low health pool is easily tear down by Wraith King physical attacks.
Oracle
[wiki] rating: 1.6 (winrate: 50% pickrate: 4%)Rubick
* Oracle's high magic damage output can easily take down Rubick's low health pool.
* Because Oracle likes to combine his spells together, the only good Spell Steal target he gives is False Promise. This scenario can be avoided by shift queueing Fortune's End and casting it immediately, as it has no cast point, or by staying in the back line of fights if out of mana.
* As a position based hero, Rubick will have a very hard time against Fortune's End due to its absurd range and very long root duration.
Bounty Hunter
* Oracle with Fortune's End and False Promise
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Faceless Void
[wiki] rating: 1.6 (winrate: 49% pickrate: 8%)Rubick
* Time Dilation, while Spell Steal with 
Aghanim's Scepter is on cooldown will make it unusable for a long time, reducing Rubick's potential.
* Rubick's own Chronosphere stolen with Spell Steal cannot stun Faceless Void.
Bounty Hunter
* Heroes who rely on invisibility, such as 
Bounty Hunter, 
Clinkz, 
Mirana, 
Nyx Assassin and 
Riki, as they will be revealed if caught by Chronosphere.
Anti-Mage
[wiki] rating: 1.6 (winrate: 47% pickrate: 13%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.
Rubick
* Mana Break quickly eats away at Rubick's low mana pool, preventing Spell Steal abilities from triggering.
* Rubick's complete lack of mobility makes him very easy for Anti-Mage to chase down with Blink.
* Anti-Mage dispels Fade Bolt damage reduction debuff with 
Manta Style or severly reduced by Counterspell.
Bristleback
[wiki] rating: 1.6 (winrate: 47% pickrate: 3%)Rubick
* Bristleback's abilities are nearly useless for Rubick to Spell Steal, as he does not gain the bonuses from Warpath.
Bounty Hunter
* 
Bristleback's 
Viscous Nasal Goo can catch and slow Bounty Hunter. 
Warpath and 
Quill Spray can defeat him quickly due to his small HP pool when compared to Bristleback's.
Broodmother
[wiki] rating: 1.2 (winrate: 53% pickrate: 1%)Bounty Hunter
* Heroes with very little to no area-of-effect abilities will struggle greatly against Broodmother: 
Sniper, 
Phantom Assassin, Nyx Assassin, 
Bane, 
Visage, Bounty Hunter.
Rubick
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: 
Shadow Shaman, Visage, 
Dazzle, 
Rubick, 
Lich.
Legion Commander
[wiki] rating: 1.2 (winrate: 48% pickrate: 9%)Bounty Hunter
* Legion Commander with Press the Attack
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time

* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest

Crystal Maiden, Lich, 
Techies, Rubick
Chaos Knight
[wiki] rating: 1.0 (winrate: 52% pickrate: 13%)Bounty Hunter
* Phantasm dispels Track, and the illusions make it difficult to Track the real Chaos Knight.
* Bounty Hunter is fragile and can easily be killed by Chaos Knight and Phantasm's illusions.
Phantom Lancer
[wiki] rating: 1.0 (winrate: 52% pickrate: 5%)Bounty Hunter
* Doppelganger dispels Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.
Zeus
[wiki] rating: 1.0 (winrate: 50% pickrate: 7%)Bounty Hunter
* Bounty Hunter has a very low health pool, allowing Zeus to burst him down quickly.
* Zeus can cast Lightning Bolt to gain True Sight in any area he suspects Bounty Hunter may be invisible or any area he thinks Bounty Hunter may have warded.
* If Bounty Hunter tries to escape a gank by using 
Shadow Walk, Zeus can gain vision of him with both Lightning Bolt and Thundergod's Wrath.
Additional:
* 
Lightning Bolt makes roaming behind enemy lines more and more difficult as Zeus becomes powerful enough to spam it. Also, Zeus' Ultimate 
Thundergod's Wrath reveals Bounty Hunter regardless of his position.
Slardar
[wiki] rating: 1.0 (winrate: 50% pickrate: 4%)Bounty Hunter
* Bounty Hunter's Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
Additional:
* 
Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* 
Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Drow Ranger
[wiki] rating: 1.0 (winrate: 49% pickrate: 11%)Rubick
* A well-timed Gust will prevent Rubick from casting abilities from Spell Steal, and his lack of capabilities and low health pool usually dies very quickly.
* Drow Ranger can dispel Fade Bolt's reduction debuff with Manta Style.
Death Prophet
[wiki] rating: 1.0 (winrate: 49% pickrate: 7%)Bounty Hunter
* Death Prophet's 
Silence allows her to prevent Bounty Hunter from escaping with Shadow Walk.
* If Bounty Hunter cannot escape with Shadow Walk while affected by Silence, she will be able to burst him down with 
Crypt Swarm and 
Spirit Siphon.
Luna
[wiki] rating: 1.0 (winrate: 48% pickrate: 5%)Bounty Hunter
* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from 
Eclipse, smart Luna will always buy 
Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.
Additional:
* Even though Luna is the kind of hero that Bounty Hunter can handle due to Shadow Walk rendering him safe from Eclipse, smart Luna will always buy Dust of Appearance, allowing her to provide vision on him to her team, and possibly, kill Bounty Hunter with Eclipse.
Spirit Breaker
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Bounty Hunter
* Spirit Breaker's 
Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.
Juggernaut
[wiki] rating: 0.6 (winrate: 54% pickrate: 18%)Bounty Hunter
* Juggernaut with Blade Fury
* Heroes that can remove the Track debuff with their skills:

Night Stalker
[wiki] rating: 0.6 (winrate: 53% pickrate: 6%)Bounty Hunter
* 
Night Stalker's 
Crippling Fear at night prevents Shadow Walk for an extended period of time and his 
Void will make Phase Boots useless. If Night Stalker has True Sight, he can shutdown Bounty Hunter's sneak kill.

Bloodseeker
[wiki] rating: 0.6 (winrate: 51% pickrate: 4%)Bounty Hunter
* Heroes with invisibility will be detected by Thirst when they have low enough health: Bounty Hunter, 
Templar Assassin, Riki, Clinkz, Weaver, 
Treant Protector, Nyx Assassin.
Additional:
* 
Rupture can turn Bounty Hunter's mobility against him, and prevents him from escaping with Shadow Walk due to the potentially heavy damage.
* 
Thirst can prevent Bounty Hunter from escaping with Shadow Walk should Bounty Hunter's health become low enough, as it provides True Sight.
Storm Spirit
[wiki] rating: 0.6 (winrate: 50% pickrate: 14%)Bounty Hunter
* Heroes that are naturally hard to gank, ranging from beefy tanks like Abaddon and Wraith King to heroes with quick escape mechanisms like Anti-Mage and Storm Spirit are also undesirable targets for a lone, roaming Bounty Hunter to scout out and initiate on.

Techies
[wiki] rating: 0.6 (winrate: 46% pickrate: 9%)Bounty Hunter
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, 
Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Witch Doctor
[wiki] rating: -1.6 (winrate: 46% pickrate: 8%)Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, 
Witch Doctor, etc.
Rubick
* 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.
Treant Protector
[wiki] rating: -1.6 (winrate: 51% pickrate: 5%)Rubick
* All of Treant Protector's abilities are worth stealing, and Rubick is able to cast them with no animation time.
Bounty Hunter
* 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.
Pudge
[wiki] rating: -1.0 (winrate: 45% pickrate: 24%)Bounty Hunter
* Track can easily keep vision on Pudge, making it very hard for him to hook Bounty Hunter or his teammates from the fog of war.
* 
Shuriken Toss cancels Dismember from great range.
Additional:
* Bounty Hunter can easily keep vision on Pudge with Track, making it difficult for Pudge to hook Bounty Hunter or his team mates.
* It's difficult for Pudge to keep up with Bounty Hunter to apply 
Rot on him due to Shadow Walk.
* Shuriken Toss cancels out 
Dismember from a good range if Bounty Hunter is not the target.
Sniper
[wiki] rating: -1.0 (winrate: 48% pickrate: 12%)Bounty Hunter
* Bounty Hunter can use Shadow Walk to get close, and 
Jinada can do massive damage and slow down Sniper on the first attack.
* Track gives additional speed to Bounty Hunter and makes 
Shadow Blade useless, allowing Bounty Hunter to easily kill him with a few attacks.
Additional:
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Magnus
[wiki] rating: -1.0 (winrate: 48% pickrate: 8%)Rubick
* 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.
Morphling
[wiki] rating: -1.0 (winrate: 48% pickrate: 7%)Rubick
* 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.
Shadow Fiend
[wiki] rating: -1.0 (winrate: 48% pickrate: 10%)Bounty Hunter
* Shuriken Toss can be used to cancel Requiem of Souls.
* Shadow Walk and Jinada allow Bounty Hunter to gank Shadow Fiend early on
* Track prevents Shadow Fiend from escaping with Shadow Blade.
Additional:
* Bounty Hunter can absolutely destroy a Shadow Fiend's game by ganking his midlane with Shadow Walk, Jinada and Shuriken Toss.
* If his lane goes bad, a Shadow Fiend usually goes to the jungle. Follow him with Shadow Walk and take half of his experience.
* Due to its ministun, Shuriken Toss is a good way to interrupt Shadow Fiend's long cast animation on 
Requiem of Souls.
Void Spirit
[wiki] rating: -1.0 (winrate: 48% pickrate: 10%)Bounty Hunter
* One hit with Jinada should be sufficient in removing Void Spirit's shield most of the time.
* Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Outworld Destroyer
[wiki] rating: -1.0 (winrate: 50% pickrate: 6%)Rubick
* 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.
Nyx Assassin
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Bounty Hunter
* Nyx Assassin wants to start ganking as soon as he gets his 
Vendetta. Keeping him Tracked prevents him from ganking, and thus from doing his job in the game.
* Nyx Assassin has a lot of armor and health regen, making the nuke damage from Shuriken Toss very good against him.
Additional:
* Track hinders Nyx Assassin's ganking attempts with Vendetta, making him an easy kill for gold as well.
Clinkz
[wiki] rating: -1.0 (winrate: 51% pickrate: 4%)Bounty Hunter
* 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.
Necrophos
[wiki] rating: -1.0 (winrate: 51% pickrate: 17%)Rubick
* 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.
Jakiro
[wiki] rating: -1.0 (winrate: 51% pickrate: 15%)Rubick
* 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.
Sand King
[wiki] rating: -1.0 (winrate: 52% pickrate: 16%)Rubick
* 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.
Bane
[wiki] rating: -1.0 (winrate: 52% pickrate: 6%)Rubick
* 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.
Vengeful Spirit
[wiki] rating: -1.0 (winrate: 52% pickrate: 7%)Rubick
* 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.
Riki
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Bounty Hunter
* Track reveals Riki while invisible and gives him a hard time, as it prevents much of his ganking capabilities. This can force Riki to buy Manta Style to dispel it.
Enigma
[wiki] rating: -1.0 (winrate: 53% pickrate: 4%)Rubick
* 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 your Black Hole.
* Aghanim's Scepter allows Rubick to potentially steal both Midnight Pulse and Black Hole, and it upgrades Black Hole to deal percentage based damage. In combination with the level 25 talent which grants spell amplification to stolen spells, and Arcane Supremecy, Rubick is one of Enigma's worst nightmares.
Templar Assassin
[wiki] rating: -0.6 (winrate: 49% pickrate: 10%)Bounty Hunter
* 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.
Invoker
[wiki] rating: -0.6 (winrate: 49% pickrate: 17%)Bounty Hunter
* Bounty Hunter and 
Slardar both have ultimates (Corrosive Haze and Track) that reveal Invoker through Ghost Walk.
Io
[wiki] rating: -0.6 (winrate: 50% pickrate: 5%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, 
Pugna, 
Skywrath Mage, 
Io, Witch Doctor, etc.
Ancient Apparition
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)Bounty Hunter
* Heroes with mobility/escape mechanisms to dodge Ancient Apparition abilites, or to easily jump on him: Riki, 
Queen of Pain, Phantom Assassin, 
Windranger, Bounty Hunter, Spirit Breaker, Night Stalker, Storm Spirit, Juggernaut, etc.
Mirana
[wiki] rating: -0.6 (winrate: 51% pickrate: 11%)Bounty Hunter
* Heroes with spells that negate invisibility such as Bounty Hunter, 
Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.
Skywrath Mage
[wiki] rating: -0.6 (winrate: 52% pickrate: 13%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Shadow Shaman
[wiki] rating: -0.6 (winrate: 52% pickrate: 13%)Bounty Hunter
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill you, Nyx being particularly deadly. Watch Slark carefully, as he can break either (but not both unless you are making a mistake) of your disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn you from prey to predator.
Pugna
[wiki] rating: -0.6 (winrate: 52% pickrate: 12%)Bounty Hunter
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:Crystal Maiden, Pugna, Skywrath Mage, Io, Witch Doctor, etc.
Chen
[wiki] rating: -0.6 (winrate: 56% pickrate: 1%)Bounty Hunter
* Invisibility heroes can sneak past Chen's creeps and pick him off: Nyx Assassin, Weaver, Bounty Hunter Riki.
Lion
[wiki] rating: -0.4 (winrate: 45% pickrate: 14%)Bounty Hunter
* Finger of Death can instantly shred many targets especially fragile Heroes like 
Keeper of the Light, 
Ancient Apparition, or Bounty Hunter.
Rubick
* 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.
Tidehunter
[wiki] rating: -0.4 (winrate: 45% pickrate: 4%)Bounty Hunter
* Tidehunter with Kraken Shell when damage received reaches the threshold.
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Rubick
* 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.
Underlord
[wiki] rating: -0.4 (winrate: 48% pickrate: 5%)Bounty Hunter
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use 
Dark Rift to get to a designated point of the map: Phantom Assassin, 
Terrorblade, 
Troll Warlord, 
Drow Ranger, Phantom Lancer, 
Chaos Knight, 
Sven, Wraith King, Bounty Hunter, 
Alchemist, Templar Assassin, Nyx Assassin, Bane.
Rubick
* All of Underlord's abilities are useful for Rubick to Spell Steal.
Crystal Maiden
[wiki] rating: -0.4 (winrate: 51% pickrate: 9%)Bounty Hunter
* 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.
Bounty Hunter
* Shuriken Toss's stun is useful for cancelling Freezing Field from a distance.
* Track can be used for revealing Crystal Maiden when she uses 
Glimmer Cape.
* Jinada does burst physical damage (which is even bigger if dealt under Track's crits), which is effective due to Crystal Maiden's low HP and armor.
* Bounty Hunter likes to stay hidden from the fight and is less likely to get caught by Crystal Maiden's spells.
Omniknight
[wiki] rating: -0.4 (winrate: 55% pickrate: 6%)Bounty Hunter
* Omniknight with Heavenly Grace
* Heroes that can remove the Track debuff with their skills:

* All of Omniknight's abilities are valuable for Rubick to Spell Steal, and Omniknight has no throwaway ability to cover his last used spell.
Monkey King
[wiki] rating: 0.0 (winrate: 46% pickrate: 8%)Rubick
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: 
Dark Seer, Riki, Rubick.
Bounty Hunter
* 
Monkey King is also hindered by Track since he relies on trees to hide him from vision.
Additional:
* Track grants vision of Monkey King, even when he's in the trees.
Marci
[wiki] rating: 0.0 (winrate: 49% pickrate: 8%)Rubick
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, 
Lina , Rubick, etc.
Rubick
* Heroes that reduce the damage that Marci can deal during her ultimate, like 
Razor, Rubick, Bane, 
Dragon Knight and 
Underlord.
Viper
[wiki] rating: 0.0 (winrate: 49% pickrate: 7%)Bounty Hunter
* Viper's poison abilities can slow Bounty Hunter's movement speed and allows to chase him with True Sight items.
* 
Nethertoxin can break Jinada, and the silence from level 25 prevents Bounty Hunter from using all of his spells.
Rubick
* 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).

Ursa
[wiki] rating: 0.0 (winrate: 51% pickrate: 9%)Bounty Hunter
* Ursa with Enrage
* Heroes that can remove the Track debuff with their skills:

Bounty Hunter
* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.
Venomancer
[wiki] rating: 0.0 (winrate: 52% pickrate: 6%)Bounty Hunter
* Venomancer's magical damage-over-time poisons greatly reduce Bounty Hunter's mobility.
* 
Venomous Gale, combined with 
Plague Wards and 
Poison Nova with True Sight items can allow Venomancer and his teammates to gank Bounty Hunter while he is roaming alone.
Rubick
* All of Venomancer's abilities are decent choices for Rubick's Spell Steal. Stealing Plague Wards makes them apply Poison Sting as well.
Bounty Hunter
* Spectre can instantly reveal Bounty Hunter's position on the activation of her ultimate
Haunt. She can also semi-reveal( visible but not target-able) Bounty Hunter by hitting him with 
Spectral Dagger.
Rubick
* None of Spectre's spells are very good for Rubick to
Spell Steal.
