Abaddon
[wiki] rating: 1.6 (winrate: 54% pickrate: 5%)Wraith King
[wiki] rating: 1.6 (winrate: 53% pickrate: 15%)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.
Skywrath Mage
* In the early-mid game, Skywrath consistently needs to use his entire mana pool to kill a hero, but Wraith King's 
Reincarnation allows him to finish off Skywrath after the first death, as Skywrath Mage will have likely expended all his mana.
Phantom Lancer
[wiki] rating: 1.6 (winrate: 53% pickrate: 6%)Skywrath Mage
* Skywrath mage also has a terrible time fighting against anything that isn't a hero. As Mystic Flare only affects heroes, his skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like 
Chaos Knight and 
Phantom Lancer, or by Heroes that summon other units like 
Lone Druid, 
Lycan and 
Beastmaster.
Bounty Hunter
* 
Doppelganger dispels 
Track.
* Bounty Hunter also has no area of effect abilities to help with the illusions.
Chaos Knight
[wiki] rating: 1.6 (winrate: 50% pickrate: 4%)Skywrath Mage
* Skywrath mage also has a terrible time fighting against anything that isn't a hero. As Mystic Flare only affects heroes, his skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
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.
Oracle
[wiki] rating: 1.6 (winrate: 48% pickrate: 4%)Skywrath Mage
* Fate Edict can be completely negate Skywrath Mage's heavy magic damage.
* Fortune End dispels Ancient Seal 
Ancient Seal.

Night Stalker
[wiki] rating: 1.2 (winrate: 53% pickrate: 8%)Skywrath Mage
* Heroes with silence such as 
Riki, 
Silencer, or 
Night Stalker prevents Skywrath Mage from using his spells.
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.
Juggernaut
[wiki] rating: 1.2 (winrate: 52% pickrate: 12%)Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high physical burst like Juggernaut or 
Phantom Assassin, the latter occasionally downing a support Skywrath in a single 
Stifling Dagger.
Bounty Hunter
* Juggernaut with Blade Fury
* 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

* 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.
Huskar
[wiki] rating: 1.0 (winrate: 54% pickrate: 5%)Skywrath Mage
* 
Berserker's Blood works proportionate to lost health, but Huskar has a decent health pool, and the attack speed granted from Berserker's Blood powers him up.
* Skywrath's armor and agility gain is very low so Huskar can outdamage him or take Skywrath down with him.
Bounty Hunter
* Huskar with Life Break
* 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

Skywrath Mage
* Heroes with high magical burst can easily kill Huskar when he is at low health: 
Lion, 
Lina, 
Skywrath Mage
Venomancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 5%)Bounty Hunter
* Venomancer's magical damage-over-time poisons greatly reduce Bounty Hunter's mobility.
* 
Venomous Gale, 
Plague Wards and 
Poison Nova with True Sight items can allow Venomancer and his teammates to gank Bounty Hunter while he is roaming alone.
Spirit Breaker
[wiki] rating: 1.0 (winrate: 51% pickrate: 20%)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.
Luna
[wiki] rating: 1.0 (winrate: 51% pickrate: 11%)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.
Anti-Mage
[wiki] rating: 1.0 (winrate: 51% pickrate: 12%)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.
Skywrath Mage
* 
Counterspell gives Anti-Mage magic resistance to negate a majority of Skywraith Mage's magical damage.
* Anti-Mage often builds 
Black King Bar and 
Manta Style which can dispel Ancient Seal and Concussive Shot.
* Huge mana cost on Mystic Flare means easy target for 
Mana Void.
* However, Anti-Mage is weak early-game to Ancient Seal until he can dispel silences, but still, Skywrath's solo kill potential is very low.
Skywrath Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Silencer, 
Shadow Shaman, 
Grimstroke, 
Witch Doctor, Riki, 
Faceless Void, Skywrath Mage, 
Puck.
Slardar
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)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.
Death Prophet
[wiki] rating: 1.0 (winrate: 49% pickrate: 3%)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.
Viper
[wiki] rating: 1.0 (winrate: 48% 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
[wiki] rating: 1.0 (winrate: 46% pickrate: 15%)Bounty Hunter
* 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.
Spectre
[wiki] rating: 1.0 (winrate: 39% pickrate: 5%)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.
Beastmaster
[wiki] rating: 0.6 (winrate: 60% pickrate: 2%)Skywrath Mage
* Skywrath mage also has a terrible time fighting against anything that isn't a hero. As Mystic Flare only affects heroes, his skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Lycan
[wiki] rating: 0.6 (winrate: 59% pickrate: 1%)Skywrath Mage
* Once you get a Black King Bar, squishy spellcasters like 
Zeus, Skywrath Mage and others will be probably easy to deal with.
Naga Siren
[wiki] rating: 0.6 (winrate: 53% pickrate: 3%)Bounty Hunter
* Naga Siren with Mirror Image
* 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
* 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.
Underlord
[wiki] rating: 0.6 (winrate: 52% pickrate: 3%)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.

Faceless Void
[wiki] rating: 0.6 (winrate: 48% pickrate: 9%)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.
Bloodseeker
[wiki] rating: 0.6 (winrate: 48% 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.
Bristleback
[wiki] rating: 0.6 (winrate: 46% pickrate: 5%)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.
Lone Druid
[wiki] rating: 0.6 (winrate: 46% pickrate: 2%)Skywrath Mage
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, 
Crystal Maiden, Shadow Shaman, Skywrath Mage etc.
Tidehunter
[wiki] rating: 0.6 (winrate: 44% pickrate: 8%)Bounty Hunter
* Tidehunter with Kraken Shell when damage received reaches the threshold.

* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Lion
[wiki] rating: 0.6 (winrate: 44% pickrate: 17%)Bounty Hunter
* Finger of Death can instantly shred many targets especially fragile Heroes like 
Keeper of the Light, Ancient Apparition, or Bounty Hunter.
Meepo
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Skywrath Mage
* Skywrath Mage's abilities are single targeted and he can't use Mystic Flare to its fullest potential, since all Meepos spread the damage between them. He also has no disables to prevent Meepo from Poofing to another one (unless he can get Ancient Seal off first).
Zeus
[wiki] rating: 0.4 (winrate: 52% pickrate: 10%)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.
Skywrath Mage
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, 
Kunkka, Puck, Skywrath Mage, 
Spirit Breaker, 
Tusk and others.
Pugna
[wiki] rating: 0.4 (winrate: 51% pickrate: 4%)Skywrath Mage
* Due to the high mana cost of his spells and the low cool down of them, Nether Ward can seriously damage Skywrath Mage if he isn't careful.
* Skywrath Mage's fragility makes him very susceptible to Pugna's high burst damage.
Additional:
* 
Nether Ward will make Skywrath Mage next to useless in fights, as his low hp pool will not allow him to sustain through the damage of the ward should he choose to cast spells. Be wary though that Skywrath's huge burst will make very quick work of Pugna's low hp should the ward be destroyed, and 
Decrepify won't help you at all.
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.
Monkey King
[wiki] rating: 0.4 (winrate: 48% pickrate: 12%)Skywrath Mage
* Skywrath Mage's very low health allows Monkey King to ambush and finish him off quickly.
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.
Clinkz
[wiki] rating: -1.6 (winrate: 49% 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.
Skywrath Mage
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, 
Queen of Pain, 
Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Ancient Apparition
[wiki] rating: -1.2 (winrate: 49% 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.
Skywrath Mage
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: 
Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.
Terrorblade
[wiki] rating: -1.0 (winrate: 45% pickrate: 4%)Skywrath Mage
* 
Arcane Bolt can target Terrorblade's low health pool in the laning phase.
* Ancient Seal can prevent Terrorblade from casting sunder.
Timbersaw
[wiki] rating: -1.0 (winrate: 45% pickrate: 6%)Skywrath Mage
* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Additional:
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using 
Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* 
Reactive Armor does not trigger on magic damage or spells, meaning that even a 
Pipe of Insight won't give him the massive sustain he normally gets from attacks.
Morphling
[wiki] rating: -1.0 (winrate: 47% pickrate: 10%)Skywrath Mage
* Arcane Bolt's low cooldown allows him to deal consistent damage to Morphling, and is a viable way to disable Linken's Sphere.
* Ancient Seal prevents Morphling from using any of his skills, giving Skywrath Mage and his team ample time to burst Morphling down.
* 
Mystic Flare coupled with a stun/root can easily burst Morphling down, especially if he has more stats shifted to Agility.
* Alternatively, Morphling can use Morph to use Skywrath Mage's own silence and nukes against him.
Sniper
[wiki] rating: -1.0 (winrate: 48% pickrate: 9%)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.
Queen of Pain
[wiki] rating: -1.0 (winrate: 49% pickrate: 17%)Skywrath Mage
* A good Skywrath Mage with quick fingers will punish Queen of Pain for blinking aggressively. Ancient Seal is a six second silence with no cast time, so he can interrupt either her Shadow Strike or Sonic Wave, and a good Mystic Flare on top of that will seal the deal for her.
* Ancient Seal also has pretty good range so he could get it off before she blinks away.
Earthshaker
[wiki] rating: -1.0 (winrate: 49% pickrate: 9%)Skywrath Mage
* Arcane Bolt allows Skywrath Mage to harass Earthshaker out of lane.
* Ancient Seal is an instant silence that can be pre-cast onto Earthshaker to disrupt his combo, before he uses 
Blink Dagger to initiate.
* Mystic Flare will nuke Earthshaker down while he stands in place during his long cast animations.
Void Spirit
[wiki] rating: -1.0 (winrate: 49% pickrate: 13%)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.
Pudge
[wiki] rating: -1.0 (winrate: 50% pickrate: 24%)Bounty Hunter
* Track can easily keep vision on Pudge, making it impossible to catch up with his Meat Hook for Bounty Hunter's teammates or him.
* It's very difficult for Pudge to use Rot on and hook Bounty Hunter due to Shadow Walk.
* 
Shuriken Toss cancels out Dismember from a good 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.
Alchemist
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Skywrath Mage
* Skywrath Mage can easily harass Alchemist in the laning phase with multiple Arcane Bolts. Additionally, if Alchemist is in the process of throwing an 
Unstable Concoction, and has no way to dispel Ancient Seal, the self stun becomes an easy set up for Mystic Flare.
* Caution, however, as a decently farmed Alchemist with {Item ID:Radiance} and {Item ID:Manta Style} can easily send illusions to harass and force Skywrath Mage out.
Weaver
[wiki] rating: -1.0 (winrate: 51% pickrate: 14%)Bounty Hunter
* Weaver with Time Lapse
* 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.
Skywrath Mage
* Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Bounty Hunter
* Bounty Hunter has a cheap way to break Linken's Sphere and keep track of Weaver while he is using Shukuchi, though both can be dispelled with Time Lapse.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Skywrath Mage
* 
Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast 
Winter's Curse on him. However, if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
Additional:
* Cold Embrace is the perfect setup for Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.
Brewmaster
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Skywrath Mage
* Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Jakiro
[wiki] rating: -1.0 (winrate: 53% pickrate: 15%)Skywrath Mage
* Ancient Seal can silence Jakiro up to 6 seconds. Also, it makes Jakiro vulnerable to magical spells.
* Skywrath Mage can burst down Jakiro with his high damage magical spells.
Chen
[wiki] rating: -0.6 (winrate: 0% pickrate: 0%)Bounty Hunter
* Invisibility heroes can sneak past Chen's creeps and pick him off: Nyx Assassin, Weaver, Bounty Hunter Riki.
Phoenix
[wiki] rating: -0.6 (winrate: 44% pickrate: 4%)Skywrath Mage
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like 
Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
Witch Doctor
[wiki] rating: -0.6 (winrate: 45% pickrate: 9%)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.
Enchantress
[wiki] rating: -0.6 (winrate: 45% pickrate: 3%)Skywrath Mage
* Heroes with nukes: Bane, 
Lich, Lion, Skywrath Mage
Additional:
* 
Untouchable is useless versus constant Arcane Bolts, and it doesn't help that her strength gain is the lowest in the game.
* A jungle Enchantress can weaken lanes and make Skywrath Mage's job easier.
* The magic amplification from Ancient Seal makes her even squishier to Skywrath and his allies' magic nukes.
Clockwerk
[wiki] rating: -0.6 (winrate: 47% pickrate: 5%)Skywrath Mage
* Skywrath Mage's Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Grimstroke
[wiki] rating: -0.6 (winrate: 47% pickrate: 12%)Skywrath Mage
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, 
Tinker, Lina
Nature's Prophet
[wiki] rating: -0.6 (winrate: 48% pickrate: 4%)Bounty Hunter
* Heroes with detection: Bounty Hunter, 
Disruptor, 
Razor, 
Slardar, 
Spectre, Spirit Breaker
Vengeful Spirit
[wiki] rating: -0.6 (winrate: 48% pickrate: 5%)Skywrath Mage
* Strong nuking supports like Skywrath Mage. Vengeful Spirit has subpar attack range, making it harder for her to harass and last hit safely. With enough pressure she can be bullied out of a lane.
Additional:
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.
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.
Windranger
[wiki] rating: -0.6 (winrate: 49% pickrate: 12%)Skywrath Mage
* 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.
Shadow Shaman
[wiki] rating: -0.6 (winrate: 50% pickrate: 8%)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.
Templar Assassin
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)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.
Mirana
[wiki] rating: -0.6 (winrate: 52% 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.
Io
[wiki] rating: -0.6 (winrate: 53% pickrate: 6%)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.
Treant Protector
[wiki] rating: -0.6 (winrate: 54% pickrate: 6%)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.
Crystal Maiden
[wiki] rating: -0.4 (winrate: 45% pickrate: 6%)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.
Shadow Fiend
[wiki] rating: -0.4 (winrate: 49% pickrate: 16%)Skywrath Mage
* Heroes with a low health pool (Crystal Maiden, Skywrath Mage etc)
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.
Phantom Assassin
[wiki] rating: -0.4 (winrate: 50% pickrate: 16%)Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high physical burst like Juggernaut or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Skywrath Mage
* While Phantom Assassin can kill Skywrath Mage in few strikes, Skywrath Mage can also do the same to her if she is not careful.
* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with 
Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Nyx Assassin
[wiki] rating: -0.4 (winrate: 51% pickrate: 5%)Skywrath Mage
* Slow-moving projectiles: Skywrath Mage, Tinker, 
Necrophos
* The nature of some abilities turn them into an easy target for a turnover from Spiked Carapace:
* Slow-moving projectiles: Skywrath Mage, Tinker, Necrophos
* Large area-of-effect with delay or require channeling: 
Enigma, Crystal Maiden, Invoker, 
Shadow Fiend, Pugna, Keeper of the Light
* Deals damage over time: Venomancer, Huskar, 
Ember Spirit, 
Dark Seer, 
Sand King, 
Doom
Additional:
* Skywrath Mage's low health makes him rather easy prey for Nyx Assassin and his lack of armor generally means he'll take the full brunt of a 
Vendetta strike.
* 
Mana Burn is annoying at all stages of the game as it turns Skywrath Mage's high intelligence growth against him.
* 
Spiked Carapace gives Nyx some degree of protection against Skywrath's spells.
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.
Legion Commander
[wiki] rating: -0.4 (winrate: 52% pickrate: 13%)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
* 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.
Skywrath Mage
* Mystic Flare can easily burst down Legion Commander while she is Dueling.
Mars
[wiki] rating: 0.0 (winrate: 46% pickrate: 14%)Bounty Hunter
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Skywrath Mage
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Techies
[wiki] rating: 0.0 (winrate: 46% pickrate: 7%)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.
Skywrath Mage
* In general, heroes such as Lion, Silencer, Skywrath Mage, Sven, 
Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.
Storm Spirit
[wiki] rating: 0.0 (winrate: 49% pickrate: 9%)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.
Skywrath Mage
* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage
Additional:
* Similar to Timbersaw, Storm Spirit builds items that don't help against silences.
* An 
Orchid Malevolence will most likely silence you first. However, if you grab a 
Eul's Scepter of Divinity, you might dispel his silence and turn the tides to your favor.
* Root and silence are Storm Spirit's ultimate counters. Skywrath Mage has a silence in his kit, and has 
Rod of Atos as his core item. If he dispels one, you cast the other, both leaving him vulnerable.
* If he builds Black King Bar, he spends 4050 gold that doesn't help him snowball effectively.
Riki
[wiki] rating: 0.0 (winrate: 50% pickrate: 5%)Skywrath Mage
* Due to his low health and armor, Riki can easily kill Skywrath Mage.
* Smoke Screen prevents Skywrath from using all of his abilities, as he does not tend to buy Black King Bar.
* However, if Skywrath Mage can easily kill Riki if he manages to root Riki with Rod of Atos or Gleipnir, followed by Dust of Appearance, Ancient Seal and Mystic Flare.
Bounty Hunter
* Track reveals him while invisible and gives Riki a hard time, as it prevents much of his ganking capabilities. This can force Riki to buy Manta Style to dispel it.
Ursa
[wiki] rating: 0.0 (winrate: 53% pickrate: 11%)Bounty Hunter
* Ursa with Enrage
* 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.
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.

Aphotic Shield removes silences, slows and stuns, possibly foiling a full-duration Mystic Flare.
Borrowed Time makes it impossible to burst 
Abaddon down, even healing him up due to Mystic Flare's damage.
