Nyx Assassin
[wiki] rating: 2.0 (winrate: 54% pickrate: 14%)Riki
[wiki] rating: 2.0 (winrate: 50% pickrate: 15%)Sniper
* Sniper has no natural escape and relies on his range and slows to keep himself safe, which you can bypass with Blink Strike and quickly deplete his miniature HP pool.
Storm Spirit
* 
Smoke Screen prevents Storm Spirit from using his abilities once inside the radius. Riki can utilize this ability to allow his team to fight around Smoke Screen so that Storm Spirit cannot spam his spells to proc Overload.
Additional:
* Smoke Cloud prevents Storm Spirit from using any of his offensive and defensive spells, rendering him unable to effectively react to Riki's attack.
Puck
[wiki] rating: 1.6 (winrate: 53% pickrate: 18%)Storm Spirit
* Any Hero with high mobility will be neutralized by dream coil: 
Queen of Pain, 
Storm Spirit, 
Ember Spirit, 
Lycan, 
Bloodseeker, 
Anti-Mage, 
Timbersaw
Sniper
* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by 
Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having Eul's Scepter of Divinity, 5 when having Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.
Treant Protector
[wiki] rating: 1.6 (winrate: 51% pickrate: 5%)Storm Spirit
* If Storm Spirit is caught in an Overgrowth, he is shut down.
* With the exception of 
Electric Vortex, he won't be able to cast any relevant skill.
Sniper
* 
Clinkz, 
Sniper, 
Lone Druid, 
Troll Warlord, 
Legion Commander and 
Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Naga Siren
[wiki] rating: 1.6 (winrate: 51% pickrate: 2%)Storm Spirit
* Any hero reliant of mobility, like Storm Spirit.
Sniper
* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Anti-Mage
[wiki] rating: 1.6 (winrate: 47% pickrate: 14%)Storm Spirit
* Because of the high mana cost of 
Ball Lightning, Storm Spirit is often vulnerable to Mana Void.
* Mana Break diminishes Storm Spirit's mobility with Ball Lightning, and Anti-Mage can catch him with Blink over short distances.
* Almost all of Storm Spirit's damage is magical, which is severely reduced by Counterspell.
* Storm Sprit has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.
Additional:
* 
Mana Break can quickly burn Storm Spirit's mana, preventing him from escaping.
* 
Blink allows Anti-Mage to catch up to Storm Spirit when he tries to use his Ball Lightning to escape.
* 
Mana Void deals massive damage to Storm Spirit as well as his teammates, as Storm Spirit depletes his mana pool by using Ball Lightning.
* 
Counterspell's passive magic resistance reduces much of Storm Spirit's magical damage dealt to Anti-Mage, and the active aspect may even make Storm Spirit disable himself.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, 
Earth Spirit, 
Io, 
Nature's Prophet, 
Pangolier, 
Puck, Queen of Pain and most notably 
Riki.
Faceless Void
[wiki] rating: 1.6 (winrate: 41% pickrate: 4%)Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as 
Drow Ranger, 
Luna, Sniper, 
Terrorblade.
Storm Spirit
* Time Dilation while 
Static Remnant and Electric Vortex are on cooldown will make these abilities unusable for a long time, reducing Storm Spirit's potential.
* Faceless Void can catch Storm Spirit during Ball Lightning with a well-timed Chronosphere or Time Walk.
Slark
[wiki] rating: 1.4 (winrate: 47% pickrate: 13%)Sniper
* Slark is a natural 
Shadow Blade carrier, and with 
Pounce Sniper has no opportunity to escape or react.
* With 
Essence Shift and 
Shadow Dance, Slark will easily win a fight against Sniper.
Additional:
* Sniper is one of the most gankable heroes in the game, and has no defenses when Pounced on by Slark.
Storm Spirit
* Pounce's leash prevents Storm Spirit from using Ball Lightning, making it hard for Storm Spirit to escape a gank from Slark.
* Dark Pact can dispel 
Orchid Malevolence's Soul Burn.
Storm Spirit
* Heroes that rely on their high mobility such as Queen of Pain, 
Slark and 
Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as 
Dust of Appearance or 
Gem of True Sight) for invisible heroes that could potentially escape your clutches.
Bane
[wiki] rating: 1.2 (winrate: 51% pickrate: 3%)Storm Spirit
* Wraith King, 
Medusa, Storm Spirit and other mana dependent heroes will have diminished impact on a fight if they survive Fiend's Grip due to its mana steal.
Sniper
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, 
Faceless Void, 
Gyrocopter, 
Juggernaut, Luna, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, 
Phantom Assassin, 
Phantom Lancer, Riki, 
Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Night Stalker
[wiki] rating: 1.0 (winrate: 53% pickrate: 5%)Storm Spirit
* 
Crippling Fear is a silence that can last up to 8 seconds during night, rendering Storm Spirit tied limited to his items in a fight.
* 
Dark Ascension allows Night Stalker to initiate on Storm Spirit across the impassable terrain around the middle lane, rendering Storm vulnerable in the early game and prevent him from snowballing.
Additional:
* Storm Spirit is absolutely helpless if caught within Night Stalker's silence range.
* Common items a Storm Spirit will build will not remove the AoE silence.
Omniknight
[wiki] rating: 1.0 (winrate: 51% pickrate: 1%)Sniper
* Being mostly a physical damage dealer, Sniper's effectiveness is greatly reduced by Omniknight's 
Guardian Angel.
* Omniknight's 
Degen Aura allows him to slow sniper and catch him. Sniper has to then use some escape item.
* Omniknight can also protect an ally from being finished off by Assassinate by using 
Purification.
Clockwerk
[wiki] rating: 1.0 (winrate: 50% pickrate: 7%)Sniper
* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.
Additional:
* Clockwerk can easily close the distance to Sniper using 
Hookshot and trap him with 
Power Cogs.
* Even though Sniper is a natural 
Hurricane Pike carrier, Sniper's low health usually means Clockwerk can finish him off with 
Battery Assault and 
Rocket Flare.
Tusk
[wiki] rating: 1.0 (winrate: 49% pickrate: 7%)Sniper
* 
Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH! damage can easily kill Sniper instantly due to his low health.
Centaur Warrunner
[wiki] rating: 1.0 (winrate: 49% pickrate: 4%)Sniper
* A 
Blink Dagger combined with 
Hoof Stomp can be used to catch Sniper.
* Centaur can also utilize 
Stampede to cover the distance.
* 
Double Edge can easily finish off Sniper after Centaur initiates on him.
* 
Retaliate punishes Sniper for focusing Centaur in teamfights.
Additional:
* 
Headshot and 
Shrapnel slow is ineffective against a team with haste (which Stampede gives).
* Commonly picked up mobility items and hasted movement during his Stampede (as well as his high health pool) make him extremely hard to kill from a distance, damaging Sniper with Retaliate and 
Blade Mail if he has one.
* A low health pool and no escape mechanism makes him an easy target for Centaur Warrunner's burst damage and initiation (even making his team possible initiators with Stampede).
Slardar
[wiki] rating: 1.0 (winrate: 48% pickrate: 6%)Sniper
* Slardar can use 
Guardian Sprint with Blink Dagger or Shadow Blade to get close, and 
Slithereen Crush will stun Sniper, making him vulnerable to Slardar's teammates.
* 
Corrosive Haze lowers Sniper's armor and makes Sniper's Shadow Blade useless, easily killing him with a few attacks.
Lifestealer
[wiki] rating: 1.0 (winrate: 48% pickrate: 5%)Sniper
* Lifestealer can close the distance to Sniper by using 
Infest on a fast or durable creep to tank Sniper's damage.
* 
Open Wounds will reduce Sniper's mobility heavily, and 
Rage's attack speed bonus helps in taking down Sniper.
Techies
[wiki] rating: 1.0 (winrate: 48% pickrate: 7%)Storm Spirit
* If Storm Spirit isn't careful, he could fall into a trap set by Techies and another hero acting as bait.
* 
Stasis Trap roots Storm Spirit for 2/3/4/5 seconds, which could be the end of Storm Spirit since he can't use Ball Lightning to escape.
Legion Commander
[wiki] rating: 1.0 (winrate: 47% pickrate: 12%)Sniper
* Sniper's low mobility and lack of defensive abilities makes him an easy gank target for the entire game, especially if Blink Dagger is picked up.
Pudge
[wiki] rating: 1.0 (winrate: 46% pickrate: 19%)Sniper
* Pudge's 
Meat Hook allows him to bring Sniper in the middle of any fight, and the pure damage does well against his high armor and low health.
* 
Dismember can lock Sniper down, which makes him highly vulnerable and gives enough time for Pudge to kill him alone.
Additional:
* Sniper has a low health pool and strength gain, making him vulnerable to Pudge's magical and pure damage.
* Sniper usually likes to deal damage away from the fight, and Meat Hook is capable of bringing him to the front lines.
* Assassinate won't do much damage against Pudge because of his high strength gain and the strength bonuses from Flesh Heap.
Meepo
[wiki] rating: 1.0 (winrate: 46% pickrate: 1%)Storm Spirit
* Earthbind, like any root, inhibits usage of Ball Lightning, eliminating Storm Spirit's mobility.
Morphling
[wiki] rating: 1.0 (winrate: 46% pickrate: 13%)Sniper
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
* Sniper's low health also makes him extremely vulnerable to Morphling's 
Ethereal Blade and Adaptive Strike combo.
Ember Spirit
[wiki] rating: 1.0 (winrate: 46% pickrate: 9%)Storm Spirit
* 
Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive and react to Storm Spirit's high magical damage.
* 
Searing Chains can root enemies up to 3 seconds, making Storm Spirit unable to escape with Ball Lightning.
* 
Fire Remnant deals high magical damage when casting multiple instances at once, granting Ember Spirit the damage to burst Storm Spirit down in the early to mid game.
Sniper
* Ember Spirit can close the distance between Sniper easily with his 
Activate Fire Remnant and further keep Sniper in place with Searing Chains.
* With the help of 
Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
Storm Spirit
* Storm Spirit is not only a potent Orchid Malevolence carrier, his Electric Vortex provides an additional disable and 
Overload provides a great slow. When paired with Static Remnant, they can cut through Flame Guard fast.
* Ball Lightning not only provides great initiation upon Ember Spirit from any position anytime, but also helps dodge Sleight of Fist.
Phantom Assassin
[wiki] rating: 1.0 (winrate: 46% pickrate: 15%)Sniper
* 
Phantom Strike allows her to jump on Sniper with increased attack speed.
* 
Coup de Grace and 
Desolator shreds Sniper's low health and armor.
* 
Blur can be activated to get within Phantom Strike's range, surprising Sniper before he has a chance to react. Its passive also reduces Sniper's overall effectiveness against Phantom Assassin, provided he hasn't purchased a 
Monkey King Bar.
Additional:
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Lycan
[wiki] rating: 0.6 (winrate: 55% pickrate: 4%)Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Sand King
[wiki] rating: 0.6 (winrate: 51% pickrate: 10%)Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress,...
Death Prophet
[wiki] rating: 0.6 (winrate: 51% pickrate: 4%)Storm Spirit
* Any heroes with stuns or silences: 
Death Prophet, 
Lion, 
Shadow Shaman, 
Skywrath Mage
Templar Assassin
[wiki] rating: 0.6 (winrate: 51% pickrate: 5%)Sniper
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: 
Lich, 
Lina, Sniper, 
Outworld Destroyer 
Zeus
Necrophos
[wiki] rating: 0.6 (winrate: 51% pickrate: 3%)Storm Spirit
* Heroes that have escape abilities (such as Queen of Pain, Storm Spirit or Timbersaw) can be either nullified by Reaper's Scythe or a complimentary item for Necrophos (like 
Rod of Atos or 
Scythe of Vyse). If Necrophos is quick enough and enters range, they can quickly, if not instantly, die if they are not quick enough.
Lion
[wiki] rating: 0.6 (winrate: 50% pickrate: 16%)Storm Spirit
* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage
Oracle
[wiki] rating: 0.6 (winrate: 50% pickrate: 9%)Sniper
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
Windranger
[wiki] rating: 0.6 (winrate: 50% pickrate: 16%)Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, 
Sven.
Skywrath Mage
[wiki] rating: 0.6 (winrate: 50% pickrate: 6%)Storm Spirit
* 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.
Disruptor
[wiki] rating: 0.6 (winrate: 49% pickrate: 9%)Storm Spirit
* At around the 10-minute mark, Disruptor would normally be level 6 or 7. This means you can have a level 3/4 glimpse along with Static Storm. A high level glimpse is enough to pull Storm back to a Static Storm even after he used Ball Lightning due to his limited mana pool at that time.
* Be careful in the late game however, as there is a good chance he will kill you straight-out before Glimpse has finished bringing him back. Therefore Glimpse would simply bring him back to safety after he's murdered you or a teammate. Of course, this is assuming he hasn't silenced you with an item.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit
Sniper
* Sniper can kill Disruptor while he is trapped by Kinetic Field from a long range.
* Sniper generally stays in the back, making it hard for Disruptor to cast any of his skills on him in lane.
Earth Spirit
[wiki] rating: 0.6 (winrate: 49% pickrate: 8%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Batrider
[wiki] rating: 0.6 (winrate: 49% pickrate: 5%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit
Invoker
[wiki] rating: 0.6 (winrate: 49% pickrate: 16%)Storm Spirit
* Heroes with mana burn: 
Nyx Assassin, 
Invoker, Outworld Destroyer, 
Pugna
Sniper
* Invoker's arsenal of magical spells are troublesome for Sniper who has low HP and high armor, which does not benefit him much against Invoker.
* Besides magical damage, he can be disarmed and repeatedly mini-stunned with 
Cold Snap, preventing him from reacting.
* Leveling 
Quas can allow Invoker to lane effectively against Sniper despite right-click harassment.
Storm Spirit
* In the early to mid game, Invoker is defenseless against Storm Spirit's ganking with Ball Lightning and Orchid Malevolence.
Queen of Pain
[wiki] rating: 0.6 (winrate: 48% pickrate: 9%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Storm Spirit
* Once you farm up an Orchid Malevolence or a Scythe of Vyse, you're suddenly a lot more fearsome to elusive heroes like Storm Spirit or even that pesky Puck.
Storm Spirit
* Heroes that rely on their high mobility such as Queen of Pain, Slark and Weaver can be constantly engaged against due to your excellent ability to chase over any terrain. Make sure you carry true sight items (such as Dust of Appearance or Gem of True Sight) for invisible heroes that could potentially escape your clutches.
Enchantress
[wiki] rating: 0.6 (winrate: 40% pickrate: 1%)Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Bounty Hunter
[wiki] rating: 0.4 (winrate: 54% pickrate: 9%)Sniper
* 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.
Storm Spirit
* 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.
Spirit Breaker
[wiki] rating: 0.4 (winrate: 50% pickrate: 8%)Sniper
* Spirit Breaker can charge towards Sniper from anywhere on the map with 
Charge of Darkness.
* 
Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with 
Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.
Storm Spirit
* Heroes that usually builds 
Linken's Sphere as a core item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit
Axe
[wiki] rating: 0.4 (winrate: 47% pickrate: 9%)Sniper
* Axe can easily close the distance to Sniper with either Blink Dagger or Shadow Blade.
* With 
Berserker's Call in combination with 
Counter Helix and 
Battle Hunger, Axe can make short work of Sniper, finishing him off easily with 
Culling Blade due to his low HP & high attack speed in the late game.
Sniper
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Doom
[wiki] rating: 0.4 (winrate: 46% pickrate: 3%)Storm Spirit
* 
Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.
Sniper
* Heroes who Sniper can kite: Sven, Wraith King, 
Kunkka, 
Doom, 
Tidehunter, 
Underlord, Troll Warlord, and etc.
Additional:
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
Enigma
[wiki] rating: -2.0 (winrate: 55% pickrate: 6%)Storm Spirit
* Using Ball Lightning with proper timing, Storm Spirit can protect himself from Malefice's instances, disjoint Demonic Conversion's attack projectiles, get out of Midnight Pulse's radius or even dodge a Black Hole.
* An isolated Enigma in the early game can be easily killed by Storm Spirit thanks his higher mobility and dueling potential. However, Storm Spirit can be killed when caught by Enigma's full combo, especially if Enigma has Black King Bar.
* Storm can kill all of Enigma's Eidolons relatively quickly without much risk, slowing down Enigma's farming speed, preventing him from split pushing, and giving Storm its considerable bounty, especially if Enigma chooses the Level 25 Talent that gives him more Eidelons.
Sniper
* Sniper has a very long range, so it is rare that Enigma can catch him in a 
Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with the level 20 talent.
* Enigma's Eidolons from 
Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with 
Maelstrom/
Mjollnir.
Additional:
* 
Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small Black Hole AoE. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation, assuming Enigma does not have Aeon Disk.
Razor
[wiki] rating: -2.0 (winrate: 55% pickrate: 4%)Sniper
* His increased attack range makes it very hard to get close enough for Static Link, Eye of the Storm and Razor's own attacks.
* Headshot procs will slow Razor heavily regardless of Storm Surge, as it will knock him back for a brief duration.
Storm Spirit
* Ball Lightning breaks 
Static Link.
* Razor has no way to catch a slippery Storm Spirit.
Shadow Fiend
[wiki] rating: -1.6 (winrate: 46% pickrate: 18%)Sniper
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his 
Shadowraze.
* Assassinate can be used to cancel Shadow Fiend's 
Requiem of Souls if he is not a target.
Additional:
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his Shadowrazes.
Storm Spirit
* Squishy heroes or heroes without hard disables or silences: 
Shadow Demon, Shadow Fiend, 
Venomancer, 
Ancient Apparition etc.
Grimstroke
[wiki] rating: -1.6 (winrate: 47% pickrate: 12%)Sniper
* Sniper's position in the far back line makes him unlikely to be hit by any of Grimstroke's abilities during teamfights.
* Sniper is relatively unaffected by the silence from Phantom's Embrace.
* Sniper's long range and fast projectile speed allows him quickly to destroy any Phantoms attacking his allies.
Storm Spirit
* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit
Luna
[wiki] rating: -1.6 (winrate: 50% pickrate: 4%)Storm Spirit
* Escape-type carries: Slark, Storm Spirit, Weaver.
Sniper
* Sniper usually sits at the back and it's hard for Luna to get close to him to attack.
* Due to Sniper's Shrapnel and his long range, Luna has a hard time taking high ground despite her Moon Glaives being fantastic for taking Barracks and buildings.
Earthshaker
[wiki] rating: -1.6 (winrate: 50% pickrate: 15%)Storm Spirit
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit
Sniper
* Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.
Additional:
* Sniper is able to kite Earthshaker with his very long range.
* Sniper can dodge Earthshaker's stuns like 
Fissure and 
Enchant Totem with mobility items such as Blink Dagger and Shadow Blade/
Silver Edge.
* Sharpnel can be used to cancel Earthshaker's Blink Dagger and preventing effective use of his 
Echo Slam in a majority of situations.
Monkey King
[wiki] rating: -1.6 (winrate: 51% pickrate: 17%)Storm Spirit
* Ball Lightning allows Storm Spirit to destroy a large amount of trees, negating 
Tree Dance. It also makes it easy to avoid 
Wukong's Command and 
Boundless Strike.
Additional:
* Ball Lightning allows Storm Spirit to easily catch up to Monkey King, destroying a large number of trees, cancelling Tree Dance, and causing Monkey King to be stunned in the process.
Sniper
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: Bloodseeker, 
Treant Protector with Eyes In The Forest, Sniper, Weaver
Venomancer
[wiki] rating: -1.2 (winrate: 50% pickrate: 5%)Sniper
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes has attack range talent can also outrange Plague Ward.
Storm Spirit
* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.
Medusa
[wiki] rating: -1.0 (winrate: 45% pickrate: 3%)Sniper
* Medusa is a fairly immobile hero that deals damage around her with 
Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her 
Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
Additional:
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Timbersaw
[wiki] rating: -1.0 (winrate: 48% pickrate: 7%)Storm Spirit
* Ball Lightning makes Storm Spirit a target difficult to chase, even for a hero as mobile as Timbersaw.
* The magical damage from Static Remnant and Overload together with Storm Spirit's high mobility allows Storm Spirit to jump on Timbersaw and burst him down, even if he tries to escape.
Tinker
[wiki] rating: -1.0 (winrate: 49% pickrate: 7%)Storm Spirit
* Storm Spirit destroys trees and ignores impassable terrains with Ball Lightning, rendering them dangerous places for Tinker to hide within.
* Ball Lightning disjoints projectile from 
Heat-Seeking Missile and damage from 
March of the Machines.
* Electric Vortex prevents Tinker from teleporting away, and Static Remnant and Overload can easily burst him down.
Additional:
* He can easily catch Tinker in the trees with Ball Lightning and kill him with Orchid Malevolence and his abilities, which deal both physical and magical damage, making them difficult for Tinker to itemize against.
Drow Ranger
[wiki] rating: -1.0 (winrate: 49% pickrate: 5%)Sniper
* Take Aim allows Sniper to outrange Drow Ranger and deal damage at her without much fear of retaliation
* Sniper can slow down Drow Ranger with Shrapnel, and both Shrapnel and Assassinate makes it easier for Sniper's team to track and take her down
Additional:
* Somewhat like Medusa, Drow Ranger is a fairly immobile hero that hopes to be able to attack without dying. Sniper should outrange her.
* Shrapnel and Assassinate provides vision over her, and slows her down, making it easier for you team to focus on taking her down
* Be careful however that if she starts attacking you, she packs a bigger punch than you thanks to 
Marksmanship.
Undying
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)Sniper
* Sniper can easily destroy 
Tombstone from long range.
Hoodwink
[wiki] rating: -1.0 (winrate: 50% pickrate: 16%)Storm Spirit
* Storm Spirit can easily make his way to hoodwink with his ultimate Ball lightning. coupled with Hoodwink's low health and magic resistance, she can be nuked easily.
Dark Willow
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Storm Spirit
* Ball Lightning allow Storm Spirit to bypass Bramble Maze, and zip back into battle if he gets hit by Terrorize.
Dark Seer
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)Sniper
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
Ursa
[wiki] rating: -1.0 (winrate: 51% pickrate: 16%)Storm Spirit
* Storm Spirit can steal 
Aegis of the Immortal during Roshan attempts through the Pit, because of his Ball Lightning.
* Ursa has no way to catch a slippery Storm Spirit, as Earthshock's slow will do nothing to stop Storm Spirit from using Ball Lightning.
Ancient Apparition
[wiki] rating: -1.0 (winrate: 52% pickrate: 9%)Storm Spirit
* Ancient Apparition's only skill to stop Storm Spirit is Cold Feet, which is bad in general when trying to stop a Storm Spirit without any other disable.
* As a fragile support with low Strength gain and no magic resistance, Ancient Apparition is vulnerable to Storm Spirit's combos.
Pugna
[wiki] rating: -1.0 (winrate: 53% pickrate: 4%)Storm Spirit
* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna
Storm Spirit
* Pugna is a very fragile hero who can easily get caught and killed by Storm Spirit's long range initiation.
* This is especially true if he has Orchid Malevolence or Scythe of Vyse.
* Pugna has no disables that can prevent Storm Spirit from escaping.
* Even though Ball Lightning requires high amount of mana, Nether Ward is ineffective since Storm Spirit is invulnerable while using it.
* Storm Spirit's other abilities cost very insignificant amount of mana for Nether Ward to be effective.
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: 
Witch Doctor, 
Crystal Maiden, Shadow Shaman, Pugna
Additional:
* Sniper's huge range makes him an unviable target to use Life Drain on, forcing Pugna to risk playing out of position to use it on Sniper.
* Sniper's Shrapnel can be used to provide vision on Nether Ward, and his range allows him to easily take it out.
* A clumsy Pugna may accidentally boost Sniper's Shrapnel and Assassinate damages if he recklessly uses Decrepify on himself or his allies.
Sven
[wiki] rating: -0.6 (winrate: 43% pickrate: 1%)Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.

* Heroes with teleports to escape Will-O-Wisp: Phantom Assassin, Puck, Queen of Pain, Storm Spirit

* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Zeus
[wiki] rating: -0.6 (winrate: 48% pickrate: 9%)Storm Spirit
* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: Lycan, Slark, Storm Spirit, 
Spectre and others.
Pangolier
[wiki] rating: -0.6 (winrate: 49% pickrate: 9%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, 
Templar Assassin, Arc Warden
Storm Spirit
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder work, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Crystal Maiden
[wiki] rating: -0.6 (winrate: 50% pickrate: 14%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna

* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Underlord
[wiki] rating: -0.6 (winrate: 53% pickrate: 8%)Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of Firestorm and Pit of Malice as well as Atrophy Aura range.
Kunkka
[wiki] rating: -0.4 (winrate: 44% pickrate: 4%)Storm Spirit
* In general, highly mobile heroes like Earth Spirit or Storm Spirit are at a disadvantage against X Marks the Spot.
* Similarly, heroes with low cooldown teleports can be afraid to split push against X Marks the Spot, such as Tinker and Nature's Prophet.
Sniper
* With his Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
Nature's Prophet
[wiki] rating: -0.4 (winrate: 45% pickrate: 7%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Storm Spirit
* Just like Batrider, his Ball Lightning can be used clear Nature's Prophet's treants and easily destroys Sprout.
* Electric Vortex prevents Nature's Prophet's escaping from Teleportation.
Magnus
[wiki] rating: -0.4 (winrate: 46% pickrate: 4%)Sniper
* Squishy core heroes (Shadow Fiend, Sniper, etc)
Sniper
* Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Mars
[wiki] rating: -0.4 (winrate: 48% pickrate: 15%)Sniper
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, 
Broodmother, Drow Ranger, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Storm Spirit
* Storm Spirit's abilities all do magical damage, which can bypass 
Bulwark.
* Ball Lightning can escape through 
Arena of Blood and it is easy to dodge 
Spear of Mars.
Additional:
* Ball Lightning makes it almost impossible to catch Storm Spirit without someone else initiating for you.
* Overload is not reduced by Bulwark and the magical damage spam can wear down Mars quickly.
Vengeful Spirit
[wiki] rating: -0.4 (winrate: 48% pickrate: 4%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit
Storm Spirit
* Ball Lightning disjoints an incoming 
Magic Missile, avoids 
Wave Of Terror, and allows Storm Spirit to easily escape if he ever gets 
Nether Swapped.
Io
[wiki] rating: -0.4 (winrate: 48% pickrate: 4%)Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Take Aim and Assassinate allow Sniper to reach Io even if it stays in the backline.
Outworld Destroyer
[wiki] rating: -0.4 (winrate: 53% pickrate: 17%)Storm Spirit
* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna
Sniper
* As Outworld Devourer has short cast ranges, a short attack range, and no gap-closing abilities, Sniper can kite and harass Outworld Devourer in lane with his long range and zone him out in fights. The continuous area damage from Shrapnel also prevents Astral-Blink escapes.
Spectre
[wiki] rating: 0.0 (winrate: 47% pickrate: 3%)Sniper
* 
Haunt instantly allows her to get up and close with Sniper, and 
Spectral Dagger makes it difficult to escape from her.
* Spectre outcarries Sniper in the late game, so Sniper must try to end the game early before Spectre comes online.
Additional:
* Spectre can reach him easily in the backlines with Spectral Dagger or teleport to him with Haunt.
* He is usually a fair distance away from his allies, so Desolate will quickly tear Sniper down.
Storm Spirit
* Ball Lightning is the ultimate counter to Spectre's entire toolkit. With this ability, he can score easy kills on Spectre without her having any means of escape early game, kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks. Furthermore, it is very difficult for Spectre to deal any substantial damage against Storm Spirit with 
Desolate, and without both a 
Manta Style and a 
Diffusal Blade he will always remain on the move. Also, Ball Lightning grants invulnerability, and as Storm Spirit likes to spam that ability, he can mitigate the damage done from 
Dispersion and 
Radiance.
Additional:
* Storm Spirit can exploit every one of Spectre's weaknesses, and thus is one of the best counters against her.
* Spectre has to be in melee range to deal damage, making her likely to trigger Static Remnants and susceptible to being kited by Overload procs.
* Electric Vortex can lock Spectre down as she doesn't like to build Black King Bar.
* Ball Lightning gives Storm Spirit multiple advantages:
* Spectre cannot evade Storm Spirit, as Ball Lightning is superior to Spectral Dagger in terms of mobility.
* Storm Spirit can kite her and her Haunt illusions when it's later in the game due to her having no form of pseudo-blinks (Reality is far inferior to Ball Lightning).
* It is very difficult for Spectre to deal any substantial damage against Storm Spirit with Desolate. Ball Lightning grants invulnerability and can mitigate damage done from Dispersion and Radiance.
Viper
[wiki] rating: 0.0 (winrate: 47% pickrate: 5%)Sniper
* 
Nethertoxin breaks Sniper's passives.
* 
Viper Strike together with 
Poison Attack can slow Sniper and tears through his low health and mobility.
Storm Spirit
* Ball Lightning allows Storm Spirit to escape through Viper Strike, wasting Viper's mana.
* It's also very easy to wait out the duration of Nethertoxin's break until Viper picks the level 25 silence talent.
Shadow Demon
[wiki] rating: 0.0 (winrate: 48% pickrate: 2%)Sniper
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: Sniper, Shadow Fiend, Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Storm Spirit
* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.
Additional:
* Shadow Demon will have a hard time catching Storm Spirit, as he can get away with Ball Lightning.
* Static Remnant will make quick work of the spawned illusions from Disruption.
* With very high mobility and usually being paired with Orchid Malevolence, he can catch Shadow Demon with ease both in ganks and in teamfights if Shadow Demon has no survivability items.
Silencer
[wiki] rating: 0.0 (winrate: 48% pickrate: 7%)Storm Spirit
* Silencer's 
Intelligence Steal can reduce Storm Spirit's damage output if he gets some kills on laning phase.
* 
Last Word and 
Global Silence will make Storm Spirit an easy target.
* Global Silence can be used to block Storm Spirit from connecting abilities after a Ball Lightning on his targets.
Sniper
* Sniper is a pure right click carry with a very long range, making it hard for Silencer to cast any of his skills on him in lane. During team-fights, Global Silence has little impact on Sniper.
Additional:
* Due to Sniper having a such a long range, he will rarely get hit by any of Silencer's spells.
* Global Silence will not hinder Sniper much as other heroes since most of his damage output comes from his attacks.
Terrorblade
[wiki] rating: 0.0 (winrate: 48% pickrate: 4%)Sniper
* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage, and Terrorblade's high armor can reduce his damage by quite a bit.
* Terrorblade is a far harder carry than Sniper is, so a well-farmed Terrorblade can easily defeat a Sniper.
Storm Spirit
* Terrorblade has low mobility, which makes it easy for Storm Spirit to kite him.
* Terrorblade gains a lot of agility and gains very low strength, which makes it easy to burst him down with Storm's magical damage.
* All of Terrorblade's abilities are easily avoided by Storm Spirit as he can simply use Ball Lightning, wasting the duration of 
Metamorphosis, 
Conjure Image, and 
Reflection.
* However, if Storm Spirit's Orchid Malevolence is on cooldown or if he doesn't have it, Terrorblade can easily use 
Sunder and kill a careless Storm Spirit.
Additional:
* Storm Spirit heavy magic damage bypass Terroblade high armor.
* Ball Lightning can either use to initiates Terroblade from distance or kite Terroblade from using Sunder as he has no source of disable to deal with Storm Spirit.
Phantom Lancer
[wiki] rating: 0.0 (winrate: 50% pickrate: 9%)Sniper
* 
Phantom Rush grants Phantom Lancer the mobility to close in the distance between Sniper.
* Phantom Lancer can dispel Sniper's Assassinate easily with 
Doppelganger and causes confusion to Sniper with the latter effect of creating an additional of 2 illusions.
* Phantom Lancer's 
Juxtapose easily can overwhelm Sniper, as his damage is mostly single-targeted.
Storm Spirit
* Ball Lightning with or without the Static Remnant talent allows Storm Spirit to destroy Phantom Lancer's illusions quickly. It is also easy to dodge 
Spirit Lance with Ball Lightning and makes Spirit Storm very hard to catch even with Phantom Rush.
Additional:
* Ball Lightning destroys illusions, avoids Spirit Lance, and makes Storm Spirit very hard to catch, even with Phantom Rush.
Weaver
[wiki] rating: 0.0 (winrate: 50% pickrate: 8%)Sniper
* 
Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of 
The Swarm and Desolator tears through Sniper's low armor.
Storm Spirit
* Ball Lightning allows Storm Spirit to close the gap between him and Weaver in no time. Once locked down with certain items, Weaver is extremely fragile to Storm Spirit and his teammates.
Bloodseeker
[wiki] rating: 0.0 (winrate: 51% pickrate: 4%)Sniper
* Sniper is suspectible to being ganked by Bloodseeker, who can easily kill Sniper due to his lack of mobility and escape mechanisms.
* Even if Sniper builds mobility items, Bloodseeker can prevent and even punish Sniper from/for using them with 
Rupture; Sniper is forced to stand still with Shadow Blade, while Hurricane Pike and Blink Dagger deals damage if he attempts to use them while Ruptured.
Additional:
* Sniper's lack of mobility and escape mechanisms makes him one of the easier heroes for Bloodseeker to gank.
Storm Spirit
* Storm Spirit is invulnerable during Ball Lightning, rendering Rupture ineffective against him.
Additional:
* Storm Spirit is invulnerable during Ball Lightning, allowing him to zip away from any ganking attempts with Rupture.
* Ball Lightning also prevents Bloodseeker from chasing down an injured Storm Spirit, or catching him in Blood Rite.
Troll Warlord
[wiki] rating: 0.0 (winrate: 52% pickrate: 9%)Storm Spirit
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like Storm Spirit.
Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Shrapnel and Headshot allows Sniper to kite Troll Warlord effectively.
* Take Aim together with certain items such as Hurricane Pike allow Sniper to sit and fire at Troll Warlord from a safe distance.
Shadow Shaman
[wiki] rating: 0.0 (winrate: 52% pickrate: 16%)Storm Spirit
* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Arc Warden
[wiki] rating: 0.0 (winrate: 53% pickrate: 5%)Sniper
* Magnetic Field's evasion completely negates Sniper's attacks unless he has True Strike.
* Sniper always positions himself far away from battles, which makes him especially vulnerable for Flux and Spark Wraith.
Storm Spirit
* Storm Spirit can hunt down Arc Warden with his Ball Lightning and kill him quickly due to his lack of escape abilities.
* None of his abilities are effective against Storm Spirit, as they can be evaded with Ball Lightning.
Broodmother
[wiki] rating: 0.0 (winrate: 56% pickrate: 2%)Sniper
* Sniper is completely helpless against Incapacitating Bite, and can be seriously damaged by Spiderlings in lane.
Storm Spirit
* Ball Lightning and Electric Vortex will catch Broodmother before she has a chance to retreat, and is able to catch her through the trees.
* Conversely, Ball Lightning also allows him to easily escape Broodmother, as she has no way to prevent him from using it before getting Orchid Malevolence.
Beastmaster
[wiki] rating: 0.0 (winrate: 56% pickrate: 7%)Storm Spirit
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.
Storm Spirit
* Heroes with AoE abilities are a bane to Beastmaster's summons: Storm Spirit, 
Magnus, Pangolier.
Sniper
*
Assassinate is easy to reflect with Spiked Carapace for massive damage.
Shrapnel's area damage can set up an easy stun with Spiked Carapace, especially when combined with Vendetta.
*
* In the early game, Sniper's low health pool and high intelligence makes him easy prey for Nyx Assassin.
Storm Spirit
*
Mana Burn is capable of removing most of Storm Spirit's large mana pool, along with dealing heavy damage and quickly depleting his chances of escaping a gank or fight.
Ball Lightning.
Static Remnant for an easy stun.
Additional:
* Mana Burn removes much-needed mana for
* Spiked Carapace triggers on
