Riki
[wiki] rating: 2.0 (winrate: 54% pickrate: 13%)Anti-Mage
[wiki] rating: 2.0 (winrate: 53% pickrate: 11%)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 Spirit 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
* Anti-Mage can close the gap with Blink. Sniper will struggle to escape once he is jumped on due to the lack of mobility.
* Counterspell reduces sniper's magic damage from 
Shrapnel and 
Assassinate. The active component can also reflect the projectile back to sniper if he dares to target Anti-Mage.
* Counterspell active is even more dangerous if Anti-Mage purchased 
Aghanim's Scepter. Aghanims scepter allows antimage to bait out snipers range tools like pike or flashbang. Otherwise the illusion will drain his mana
* Sniper often relies on mana to use items for escaping, and his abilities cost a lot of mana. Mana break drains Sniper's mana and takes away Sniper's mean to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of sniper easily.
Nyx Assassin
[wiki] rating: 2.0 (winrate: 50% pickrate: 4%)Storm Spirit
* Mana Burn removes much-needed mana for Ball Lightning.
* Spiked Carapace triggers on 
Static Remnant for an easy stun.
Additional:
* 
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.
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.
Tusk
[wiki] rating: 2.0 (winrate: 49% pickrate: 15%)Storm Spirit
* Tusks damage/stun is enough to obliviate Storm Spirit before he can do anything.
* Tusk is a common 
Blink Dagger carrier, and once he reaches Level 18, 
Walrus PUNCH! deals roughly half of Storm Spirit's health alone, It also stuns for a long enough time for Tusk to 
Snowball Storm Spirit, stunning him even more, If that hasn't finished him off, the damage from 
Ice Shards probably will. Combined with 
Tag Team, which adds bonus damage to Tusks attacks, Storm Spirit is unlikely to survive Tusk initiating on him
* Walrus PUNCH is even more potent if he uses a 
Silver Edge instead
* However while Ball Lightning doesn't disjoint Snowball, if used before Tusk hits with Snowball, prevents the stun and damage from being applied
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.
Treant Protector
[wiki] rating: 1.6 (winrate: 53% pickrate: 16%)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: 3%)Storm Spirit
* 
Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: 
Phantom Assassin, 
Magnus, 
Slark, 
Riki, 
Faceless Void, Storm Spirit.
Sniper
* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Puck
[wiki] rating: 1.6 (winrate: 48% pickrate: 9%)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.
Slark
[wiki] rating: 1.4 (winrate: 51% pickrate: 17%)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.
Sniper
* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.
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: 48% pickrate: 2%)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.
Meepo
[wiki] rating: 1.0 (winrate: 56% pickrate: 1%)Storm Spirit
* Earthbind, like any root, inhibits usage of Ball Lightning, eliminating Storm Spirit's mobility.
Omniknight
[wiki] rating: 1.0 (winrate: 55% pickrate: 3%)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, then using 
Heavenly Grace which grants a massive strength boost.
Lone Druid
[wiki] rating: 1.0 (winrate: 55% pickrate: 3%)Storm Spirit
* True Form gives Lone Druid a huge amount of health that no amount of Ball Lightning will chip through.
* 
Entangling Claws can mean a very quick end to the Storm Spirit as it prevents him from using Ball Lightning all together.
* Storm Spirit is a single target nuker, with the Shard Lone Druid can always fear him away from himself or the bear, defending the target he does not go on. This is assuming he cannot try and proc his entangle or a potential 
Skull Basher.
Night Stalker
[wiki] rating: 1.0 (winrate: 52% pickrate: 4%)Storm Spirit
* 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.
Additional:
* 
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.
Legion Commander
[wiki] rating: 1.0 (winrate: 51% pickrate: 13%)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.
Centaur Warrunner
[wiki] rating: 1.0 (winrate: 51% pickrate: 7%)Sniper
* 
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: 50% pickrate: 4%)Sniper
* Slardar can use 
Guardian Sprint with Blink Dagger or 
Shadow Blade to get close, and 
Slithereen Crush will stun Sniper and slow him, 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.
Skywrath Mage
[wiki] rating: 1.0 (winrate: 50% pickrate: 10%)Storm Spirit
* 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.
Primal Beast
[wiki] rating: 1.0 (winrate: 49% pickrate: 9%)Sniper
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool. Should Sniper acquire an item of escape, Primal Beast can still delay him with Pulverize. Overall, Sniper is an ideal target for Primal Beast to constantly threaten in all stages of the game, and it can force Sniper to itemise for him.
Clockwerk
[wiki] rating: 1.0 (winrate: 49% pickrate: 8%)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.
Pudge
[wiki] rating: 1.0 (winrate: 49% pickrate: 29%)Sniper
* 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.
* Shrapnel will be mostly blocked by Flesh Heap's active.
Additional:
* 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.
Techies
[wiki] rating: 1.0 (winrate: 48% pickrate: 10%)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 and 
Blast Off! silences for 4/5/6/7 seconds, which effectively prevents Storm Spirit from using Ball Lightning to escape for a lengthy duration.
Ember Spirit
[wiki] rating: 1.0 (winrate: 48% pickrate: 11%)Storm Spirit
* 
Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive against 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.
Sven
[wiki] rating: 1.0 (winrate: 48% pickrate: 2%)Storm Spirit
* Heroes who cannot prevent Sven from killing towers will often struggle from a small map very early, such as Phantom Assassin, Storm Spirit and Phantom Lancer.
Sniper
* Past the early game, Sniper is an easy target for Sven to jump on with Aghanim's Scepter.
* Sven's high armour and health pool makes it difficult for Sniper to focus, as his main source of damage is his right click.
* Sniper is very squishy, and will not stand a chance against Sven head on.
Sniper
* Special mention to 
Sven as he may not be able to get close, but if he does, 
God's Strength will make very short work of Sniper.
Faceless Void
[wiki] rating: 1.0 (winrate: 48% pickrate: 9%)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.
Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.
Sniper
* Heroes that can easily kill Faceless Void from outside his Cronosphere; Sniper, 
Skywrath Mage, etc.
Chaos Knight
[wiki] rating: 1.0 (winrate: 47% pickrate: 3%)Sniper
* Sniper is very fragile, along with his low movement speed, make an exceptionally easy target for Chaos Knight to initiate on.
* Sniper has no innate ability to deal with 
Phantasm or escape a 
Reality Rift and 
Chaos Bolt combo.
* In most cases, Sniper likes to stay far in the backline to deal damage, thus he is vulnerable if Chaos Knight manages to jump in the back line, which will usually spell a quick end for Sniper.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 25%)Sniper
* In the mid to late game, the physical attack from Sniper can be painful to go through as 
Rubick. However with the help of Rubick's teammates, the abilities of Sniper can turn against his team.
* Shrapnel is a great wave-clear ability, and helps with scouting the area.
* Shrapnel already has a long cast range, and together with 
Arcane Supremacy Rubick can put constant damage on Sniper while he stays at back.
* Assassinate, if stolen, can be cast to assist a gank while Rubick stays at a range that can merely be found in the area, damaging heroes in the backline including Sniper.
* Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to 406.2/611.1/819(531.2/805.1/1079) without considering any further amplification source.
* With Aghanim's Scepter, Assassinate becomes an ability with a reliable 1.5 second stun, massive damage, short cooldown and over 3000 cast range which should not be made light of.
* Shrapnel is used frequently and can be easily stolen; Assassinate has a long cast animation for Rubick to forsee the chance to steal.
Phantom Assassin
[wiki] rating: 1.0 (winrate: 46% pickrate: 10%)Sniper
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Morphling
[wiki] rating: 1.0 (winrate: 44% pickrate: 8%)Sniper
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
Lycan
[wiki] rating: 0.6 (winrate: 57% pickrate: 3%)Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Death Prophet
[wiki] rating: 0.6 (winrate: 55% pickrate: 11%)Storm Spirit
* Any heroes with stuns or silences: 
Death Prophet, 
Lion, 
Shadow Shaman, Skywrath Mage
Clinkz
[wiki] rating: 0.6 (winrate: 52% pickrate: 7%)Sniper
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, 
Bounty Hunter.
Oracle
[wiki] rating: 0.6 (winrate: 51% pickrate: 4%)Sniper
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
Necrophos
[wiki] rating: 0.6 (winrate: 50% pickrate: 7%)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.
Sand King
[wiki] rating: 0.6 (winrate: 50% pickrate: 6%)Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress,...
Earth Spirit
[wiki] rating: 0.6 (winrate: 49% pickrate: 3%)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.
Windranger
[wiki] rating: 0.6 (winrate: 49% pickrate: 10%)Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.
Disruptor
[wiki] rating: 0.6 (winrate: 48% pickrate: 10%)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.
Invoker
[wiki] rating: 0.6 (winrate: 48% pickrate: 14%)Storm Spirit
* Heroes with mana burn: 
Nyx Assassin, 
Invoker, 
Outworld Destroyer, 
Pugna, Lion
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.
Batrider
[wiki] rating: 0.6 (winrate: 48% pickrate: 5%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.
Templar Assassin
[wiki] rating: 0.6 (winrate: 48% pickrate: 4%)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
Queen of Pain
[wiki] rating: 0.6 (winrate: 46% pickrate: 6%)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.
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
* 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: 46% pickrate: 2%)Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Lion
[wiki] rating: 0.6 (winrate: 45% pickrate: 10%)Storm Spirit
* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion
Bounty Hunter
[wiki] rating: 0.4 (winrate: 51% pickrate: 7%)Sniper
* 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.
Axe
[wiki] rating: 0.4 (winrate: 49% pickrate: 9%)Sniper
* Axe can easily close the distance to Sniper with Blink Dagger.
* 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.
Lifestealer
[wiki] rating: 0.4 (winrate: 49% 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 and 
Ghoul Frenzy will reduce Sniper's mobility heavily, and 
Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate.
Storm Spirit
* Heroes with escape abilities : Anti-Mage 
Dark Seer Slark Storm Spirit 
Windranger Weaver can kite Lifestealer due to him having no lockdown
Spirit Breaker
[wiki] rating: 0.4 (winrate: 48% pickrate: 9%)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
Muerta
[wiki] rating: 0.4 (winrate: 45% pickrate: 13%)Sniper
* Sniper's 
Take Aim can be wasted with either Muerta's 
Pierce the Veil or a well aimed 
Dead Shot.
* Dead Shot can make Sniper run into the battle, when Sniper want's to stay as far as possible from it.
* Sniper relies heavily on his main attacks, which is useless against Pierce the Veil.
Storm Spirit
* Gap closers (Storm Spirit, Pudge) can easily kill Muerta.
Enigma
[wiki] rating: -2.0 (winrate: 50% pickrate: 3%)Storm Spirit
* 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.
* Storm can zip through 
Black Hole stunning Enigma while he's channelling until Enigma buys Black King Bar.
Sniper
* 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 area-of-effect for Black Hole. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation.
* In the early game, Sniper can cancel Enigma's Black Hole with Assassinate's ministun. Due to the absolutely ginormous 3000 cast range on Assassinate, Sniper does not need to be too close to Enigma to cancel his Black Hole. Aghanim's Scepter upgraded Assassinate can also stun Enigma for a longer duration.
* Both Shrapnel and Assassinate put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate Black King Bar.
Additional:
* 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 Aghanim's Scepter.
* Enigma's Eidolons from 
Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with 
Maelstrom/
Mjollnir.
Grimstroke
[wiki] rating: -1.6 (winrate: 46% pickrate: 4%)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
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.
Monkey King
[wiki] rating: -1.6 (winrate: 47% pickrate: 8%)Storm Spirit
* 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.
Additional:
* 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.
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
Shadow Fiend
[wiki] rating: -1.6 (winrate: 48% pickrate: 18%)Storm Spirit
* Squishy heroes or heroes without hard disables or silences: 
Shadow Demon, Shadow Fiend, 
Venomancer, 
Ancient Apparition etc.
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 Shadowrazes.
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 
Shadowraze.
* Assassinate when upgraded with Aghanim's Scepter can be used to cancel Shadow Fiend's 
Requiem of Souls.
Juggernaut
[wiki] rating: -1.6 (winrate: 50% pickrate: 11%)Storm Spirit
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Sniper
* Juggernaut deals most of his damage in the melee range and has no gap-closer. Sniper can easily harrass Juggernaut from afar with his long-ranged attacks and {Ability ID:Headshot|Sniper|16px} procs.Should Juggernaut decide to advance,Sniper has enough time to react and back off.
* Sniper's long range attack can destroy 
Healing Ward from a safe range, preventing any healing done to Juggernaut and/or his teammates.
* However, if Sniper is badly positioned, Juggernaut can easily terminate him.
Venomancer
[wiki] rating: -1.6 (winrate: 50% pickrate: 4%)Storm Spirit
* Squishy heroes or heroes without hard disables or silences: Shadow Demon, Shadow Fiend, Venomancer, Ancient Apparition etc.
Sniper
* Sniper can easily destroy 
Plague Ward from long range.
Earthshaker
[wiki] rating: -1.6 (winrate: 51% pickrate: 10%)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, 
Force Staff/
Hurricane Pike 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.
Razor
[wiki] rating: -1.6 (winrate: 52% pickrate: 7%)Storm Spirit
* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.
Additional:
* Ball Lightning breaks 
Static Link.
* Razor has no way to catch a slippery Storm Spirit.
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.
Pugna
[wiki] rating: -1.4 (winrate: 47% pickrate: 3%)Storm Spirit
* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion
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
* 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.
Luna
[wiki] rating: -1.2 (winrate: 49% pickrate: 2%)Storm Spirit
* Escape-type carries: Slark, Storm Spirit, Weaver.
Sniper
* Heroes that outrange Luna can be a problem for her: Drow Ranger, Sniper.
Terrorblade
[wiki] rating: -1.0 (winrate: 45% pickrate: 2%)Sniper
* Heroes who have high health are a problem for Sniper because he likes to attack the closest target and sit at the back, much like a Terrorblade so when that hero doesn't die; he's forced to show his position for a very long time: 
Centaur Warrunner, Legion Commander, 
Primal Beast.
Additional:
* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage in the late game, and Terrorblade's high armor can reduce his damage significantly.
* 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 has heavy magic damage that bypasses Terroblade's 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.
Sniper
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: 
Bane, 
Lifestealer, 
Spectre, 
Chaos Knight, 
Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get 
Manta Style as quickly as possible.
Medusa
[wiki] rating: -1.0 (winrate: 45% pickrate: 1%)Sniper
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Additional:
* 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.
Timbersaw
[wiki] rating: -1.0 (winrate: 46% pickrate: 5%)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.
Hoodwink
[wiki] rating: -1.0 (winrate: 47% pickrate: 13%)Storm Spirit
* Storm Spirit can easily make his way to Hoodwink with his ultimate Ball lightning, and coupled with Hoodwink's low health and magic resistance, she can be nuked easily.
* Additionally, Ball lightning can destroy a small amount of trees in its destination. Combined with Storm Spirit's frequent usage of his ultimate, he can clear out an area of trees while simultaneously attacking him and dodging incoming attacks.
Dark Willow
[wiki] rating: -1.0 (winrate: 51% pickrate: 4%)Storm Spirit
* Ball Lightning allow Storm Spirit to bypass Bramble Maze, and zip back into battle if he gets hit by Terrorize.
Io
[wiki] rating: -1.0 (winrate: 51% 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.
Storm Spirit
* Heroes that can easily bypass Io's allies to get to Io: Riki, 
Tusk, Clinkz, Sniper, Slark, Phantom Assassin, 
Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Sniper
* Take Aim and Assassinate allow Sniper to reach Io even if it stays in the backline.
Dark Seer
[wiki] rating: -1.0 (winrate: 52% pickrate: 2%)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.
Undying
[wiki] rating: -1.0 (winrate: 52% pickrate: 10%)Sniper
* Sniper can easily destroy 
Tombstone from long range.
Huskar
[wiki] rating: -1.0 (winrate: 53% pickrate: 6%)Storm Spirit
* Ball Lightning, if timed correctly, and in the right place, can drag Huskar using Life Break all the way to fountain. Or you could also lure him on top of a pillar or into a techies minefield.
Tinker
[wiki] rating: -1.0 (winrate: 56% pickrate: 11%)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.
Pangolier
[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
* 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 works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Sniper
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, 
Templar Assassin, 
Arc Warden
Witch Doctor
[wiki] rating: -0.6 (winrate: 48% pickrate: 15%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: 
Witch Doctor, 
Crystal Maiden, Shadow Shaman, Pugna
Tiny
[wiki] rating: -0.6 (winrate: 48% pickrate: 13%)Sniper
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Wraith King
[wiki] rating: -0.6 (winrate: 48% pickrate: 4%)Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, 
Kunkka, 
Doom,

Crystal Maiden
[wiki] rating: -0.6 (winrate: 49% pickrate: 13%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Zeus
[wiki] rating: -0.6 (winrate: 49% pickrate: 14%)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.
Ancient Apparition
[wiki] rating: -0.6 (winrate: 50% pickrate: 5%)Storm Spirit
* 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.
Additional:
* 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.
Gyrocopter
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)Storm Spirit
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Jakiro
[wiki] rating: -0.6 (winrate: 51% pickrate: 12%)Sniper
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: Death Prophet, Sniper, 
Tinker, Windranger.
Drow Ranger
[wiki] rating: -0.6 (winrate: 51% pickrate: 18%)Sniper
* Heroes who outrange Drow Ranger such as Sniper, Tinker.
Underlord
[wiki] rating: -0.6 (winrate: 51% pickrate: 3%)Sniper
* Melee heroes who may struggle to get close to Sniper: 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.
Mirana
[wiki] rating: -0.6 (winrate: 53% pickrate: 15%)Storm Spirit
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Visage
[wiki] rating: -0.6 (winrate: 55% pickrate: 2%)Sniper
* Heroes with long ranged attacks or abilities can harass Visage from afar like 
Phoenix and Sniper.
Nature's Prophet
[wiki] rating: -0.4 (winrate: 46% pickrate: 12%)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
* Ball Lightning can be used to clear Nature's Prophet's Treants and easily destroys Sprout.
* Electric Vortex prevents Nature's Prophet's escaping using Teleportation.
Shadow Demon
[wiki] rating: -0.4 (winrate: 47% pickrate: 1%)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
* 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.
Kunkka
[wiki] rating: -0.4 (winrate: 47% pickrate: 3%)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.
Shadow Shaman
[wiki] rating: -0.4 (winrate: 49% pickrate: 6%)Storm Spirit
* In general, squishy heroes that rely on escape often struggles against the amount of disables Shadow Shaman can bring. Queen of Pain, Anti-Mage and Storm Spirit are among these.
Sniper
* Sniper can easily destroy 
Mass Serpent Ward from long range
Vengeful Spirit
[wiki] rating: -0.4 (winrate: 49% pickrate: 5%)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.
Phantom Lancer
[wiki] rating: -0.4 (winrate: 50% pickrate: 2%)Sniper
* Carry heroes who can close the gap reliably are very problematic: Phantom Lancer, Ember Spirit, Phantom Assassin.
Storm Spirit
* Storm Spirit has multiple AoE abilities to deal with Phantom Lancer, especially with Aghanim's Scepter.
* Ball Lightning destroys illusions, avoids Spirit Lance, and makes Storm Spirit very hard to catch, even with Phantom Rush.
Additional:
* 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.
Magnus
[wiki] rating: -0.4 (winrate: 51% pickrate: 15%)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.
Outworld Destroyer
[wiki] rating: -0.4 (winrate: 51% pickrate: 10%)Storm Spirit
* Heroes with mana burn: Nyx Assassin, Invoker, Outworld Destroyer, Pugna, Lion
Sniper
* As Outworld Destroyer has short cast ranges, a short attack range, and no gap-closing abilities, Sniper can kite and harass Outworld Destroyer in lane with his long range and zone him out in fights. The continuous area damage from Shrapnel also prevents Astral-Blink escapes.
* However, in the late game, Outworld Destroyer's massive damage can overwhelm Sniper once he obtains Blink Dagger, Force Staff etc. to close the gap.
Ursa
[wiki] rating: -0.4 (winrate: 52% pickrate: 15%)Sniper
* Early game gankers can make life very difficult for a Sniper if he keeps being caught: 
Ursa, Pudge, Earth Spirit.
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.
Silencer
[wiki] rating: -0.4 (winrate: 52% pickrate: 15%)Storm Spirit
* Basically, Heroes that heavily rely on abilities for damage or escape, such as Queen of Pain and Storm Spirit.
Additional:
* 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 prevent Storm Spirit from connecting abilities after a Ball Lightning on his targets.
Sniper
* 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.
Additional:
* 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.
Mars
[wiki] rating: 0.0 (winrate: 46% pickrate: 10%)Sniper
* Even if he can slow Mars down with Shrapnel and Headshot, Mars can tank Sniper's physical damage simply by facing him with Bulwark, allowing him to endure his auto-attacks into the late-game. Should Sniper choose to attack someone else, Mars can redirect his projectiles with Bulwark's active ability.
* Sniper's poor mobility makes him very vulnerable to Arena of Blood, especially in the early game. Mars can also take advantage of this by pushing him closer to the front line with Spear of Mars.
Storm Spirit
* 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.
Additional:
* 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.
Doom
[wiki] rating: 0.0 (winrate: 47% pickrate: 8%)Storm Spirit
* 
Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.
Sniper
* 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.
Marci
[wiki] rating: 0.0 (winrate: 48% pickrate: 7%)Sniper
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, 
Lina , Rubick, etc.
Storm Spirit
* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and Force Staff.
Bloodseeker
[wiki] rating: 0.0 (winrate: 49% pickrate: 3%)Sniper
* 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, 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.
Additional:
* Storm Spirit is invulnerable during Ball Lightning, rendering 
Rupture ineffective against him.
Viper
[wiki] rating: 0.0 (winrate: 49% pickrate: 4%)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.
Troll Warlord
[wiki] rating: 0.0 (winrate: 50% pickrate: 2%)Storm Spirit
* Mobility heroes will often be rooted by Troll Warlord and unable to escape, like Storm Spirit.
Sniper
* Melee heroes who may struggle to get close to Sniper: 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.
Weaver
[wiki] rating: 0.0 (winrate: 50% pickrate: 3%)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.
Beastmaster
[wiki] rating: 0.0 (winrate: 51% pickrate: 2%)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.
Spectre
[wiki] rating: 0.0 (winrate: 51% pickrate: 11%)Sniper
* 
Haunt instantly allows her to get up and close with Sniper, and 
Spectral Dagger makes it difficult to escape from her.
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.
* 
Dispersion reflect or reduce his damage, making her hard to take down even at late game.
Storm Spirit
* 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.
* To mitigate this, Spectre needs a team with hard disable to take Storm Spirit out.
Additional:
* 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 Manta Style and 
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.
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: 54% pickrate: 3%)Sniper
* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when Shrapnel is on cooldown.
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.
Storm Spirit
* Smoke Cloud prevents Storm Spirit from using any of his offensive and defensive spells, rendering him unable to effectively react to Riki's attack.
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:
*
Sniper
* Sniper has no natural escape and relies on his range and slows to keep himself safe, which Riki can bypass with Blink Strike and quickly deplete his miniature HP pool.
