* Lina defeats Sniper on the mid, because she has the same attack range as him, and her Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.
Additional:

* Lina builds Shadow Blade (and upgrades it into a Silver Edge), which makes it hard for Ancient Apparition to land his abilities.
* Laguna Blade can kill Ancient Apparition easily due to his low health pool and lack of mobility.

* Shadow Step and Haunt from Aghanim's Scepter instantly allows Spectre to get up and close with Sniper, and Spectral Dagger makes it difficult for Sniper 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.

* As Ancient Apparition likes to stay far away from the fight to get full effectiveness from Ice Blast, he is a very good target for a Haunt gank.
* Ancient Apparition also has no hard disables and escape spells, making him an easy kill for Spectre.

* Viper Strike breaks Sniper's passives.
* Corrosive Skin allows Viper to deal more damage to Sniper than Sniper deals to him when laning, especially by briefly stepping into Shrapnel.
* Nethertoxin together with Poison Attack can slow Sniper and tears through his low health and mobility.

* Corrosive Skin minimizes the damage Viper takes from all of Ancient Apparition's abilities.
* Ancient Apparition's slow movement speed, squishy nature, and lack of escape abilities can easily be taken advantage of through Poison Attack and Viper Strike.

* 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.

* Riki can get on top of Ancient Apparition very easily with Blink Strike. This can also double as a way to dodge Ice Blast, along with Tricks of the Trade.
* Ancient Apparition will frequently resort to casting Ice Blast right before dying. Smoke Screen can be used to prevent this, stopping Ancient Apparition from having any impact.

* 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. This is seriously detrimental for Sniper as he is prone to buying Khanda to boost effects of the Assassinate.
* 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 means to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of Sniper easily.

* Anti-Mage can Blink away from Cold Feet or build a Manta Style to dispel it.
* Counterspell minimizes the damage Anti-Mage takes from all of Ancient Apparition's abilities.
* Mana Break and Mana Void deal a lot of damage to Ancient Apparition due to his high mana pool.
Additional:
* Anti-Mage easily Blinks out of Cold Feet's freeze radius.
* Ancient Apparition lacks mobility, thus making him fall easily to Mana Void.
* Counterspell reduces all Ancient Apparition's spell damage.

* 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.

* Time Lapse allows Weaver (or an ally if upgraded with Aghanim's Scepter) to regain HP while affected by Ice Blast.
* Shukuchi completely ignores the slow from Ice Vortex and helps him escape the freeze range of Cold Feet.
Additional:
* Cold Feet is extremely easy to nullify with Shukuchi.
* Ice Vortex does not slow Weaver in Shukuchi.
* Time Lapse will still affect his health, even when hit by Ice Blast.
* Ancient Apparition has no escapes or saves and is very squishy, making him an easy target for Weaver to get on top of.

* 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.

* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both Cold Feet and Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.

* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.

* False Promise can dispel the stun from Cold Feet and can save an ally that's about to shatter from Ice Blast, even allowing healing with Purifying Flames by delaying it until after the debuff expires.
* Purifying Flames allows Oracle to deny his allies if they're affected by Ice Blast. If he brings his allies' health to or below the shatter threshold, it will count as him denying the ally. However, this does not work on Oracle himself.
* Fate's Edict provides 100% magic resistance, making it good against all of Ancient Apparition's abilities at all stages of the game.
* Fortune's End can dispel Cold Feet from allies.
Additional:
* False Promise can prevent the shatter from Ice Blast and Fate's Edict can protect an ally from the magical damage over time for a while.
* Oracle can deny allies who are frostbitten. If he uses Purifying Flames to reach the shatter threshold, it will count as a deny.
* Fortune's End can dispel Cold Feet on affected allies, preventing them from getting frozen.

* 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.

* 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.

* 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.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Additional:
* Stifling Dagger and Phantom Strike allow Phantom Assassin to close the gap with Sniper and prevent his escape.
* Blur allows Phantom Assassin to approach Sniper while invisible and dodge much of Sniper's damage. It can also disjoint Assassinate.
* Coup De Grace quickly cuts through Sniper's low health; one or two procs will usually kill him.
* Fan of Knives from Aghanim's Shard can deal damage to Sniper's maximum health and disable Headshot and Take Aim.

* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.

* 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.

* 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.

* 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.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.

* Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has fast summons, both his wolves from Summon Wolves can do heavy damage to Ancient Apparition due to his immobility and low armor.

* Storm Spirit can close the distance towards Sniper very easily with his ultimate Ball Lightning.
Additional:
* Sniper is very squishy and cannot deal with heroes that jump onto him and lock him down. Storm Spirit closes the gap in a fight against Sniper, and Sniper has no way to escape except for some items.
* Storm Spirit can dodge Assassinate with a correctly timed Ball Lightning.

* 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.

* Sniper lacks any protection against Lion's disables early in the game.
* Lion's Earth Spike and Finger of Death may roughly hit Sniper at the latter increased attack range, making it possible to gank and to disable him from afar in clashes.
* Finger of Death is incredibly dangerous for Sniper as it may shred him away from fights, or in the worst scenario, cause his death.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, Bounty Hunter.

* Ancient Apparition has no escape or reliable control and is very fragile, which makes him an easy target for anyone who can get on top of him, like Phantom Assassin or Clinkz.

* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.

* 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.

* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.

* For the same reason, he has to be slightly more cunning when playing against heroes that can scout the treeline, such as Ancient Apparition and his Ice Vortex and Shadow Demon and his Shadow Poison.

* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, Monkey King, Sven.

* 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.

* Sniper's lack of mobility and escape mechanisms makes him one of the easier heroes for Bloodseeker to gank.

* 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.

* Primal Split makes Brewmaster invulnerable for the duration, rendering effects of Cold Feet and Ice Blast useless.
* Dispel Magic can dispel Cold Feet from allies.
* Brewmaster can easily run Ancient Apparition down with the slow from Thunder Clap and Cinder Brew.

* Dissimilate and Astral Step allow Void Spirit to quickly escape from Cold Feet.
* Void Spirit deals both magical and physical damage, which makes Ancient Apparition an easy target to ambush.
* If Void Spirit purchases Aghanim's Scepter, the silence provided by Resonant Pulse can disrupt Ancient Apparition during fights, as he is entirely reliant upon spells to contribute.

* 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).

* Tinker is one of the few heroes who is able to defeat a Sniper on the center line thanks to his long-ranged abilities.
* Laser allow Tinker to deal damage to Sniper and blind him, causing him to miss attacks more often.
* Heat-Seeking Missile can deal heavy damage to Sniper on lane.
* Defense Matrix allow Tinker to save himself or allies from Assassinate.
* Warp Flare from Aghanim's Shard allows Tinker to teleport Sniper away from himself, while also reducing both his attack range and cast range. If Sniper is teleported near Tinker's allies with Warp Flare, he will be bursted down in no time.
Additional:
* Tinker is one of the few characters in Dota 2 who is able to defeat a Sniper on the center line – Tinker. On the center line, he gains an advantage over his opponent, and later acquires additional control. It is these abilities that the enemy should have in the game against the 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 a safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get close 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.

* 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.

* Sniper is very fragile and has low movement speed, making 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 on him in the back line, which will usually spell a quick end for 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. Aghanim's Shard upgraded Dismember will also allow Pudge to save an ally from Assassinate.

* 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.

* 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.

* Sunder allows Terrorblade (or an ally) to regain HP while affected by Ice Blast.
* Terrorblade often buys Manta Style which can dispel Cold Feet.
Additional:
* Sunder is not affected by Ice Blast and will still swap health with any target as usual.

* 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.

* 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.

* 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!'s very high physical damage output can easily kill Sniper instantly due to his low health and armor.

* Carry heroes who can close the gap reliably are very problematic: Phantom Lancer, Ember Spirit, Phantom Assassin.

* Phantom Lancer can dispel or escape from Cold Feet with Doppelganger and Phantom Rush, respectively. Phantom Lancer also frequently builds a Manta Style which dispels Cold Feet.
* Ancient Apparition has trouble dealing with Phantom Lancer's illusions due to a lack of Area of Effect damage other than Ice Blast.
* Phantom Lancer tends to build a Diffusal Blade, which greatly amplifies his damage against Ancient Apparition due to Ancient Apparition's high mana pool.
* Ancient Apparition has no escape/mobility mechanisms, making him an easy target for Phantom Lancer at any stage of the game.

* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.

* Leap allows Mirana to easily escape the freezing range of Cold Feet. Mirana also tends to build Manta Style which dispels Cold Feet.
* During Moonlight Shadow, the invisibility makes it hard to catch Mirana's team with Ice Blast.
* Ancient Apparition's lack of mobility/escape capabilities makes him an easy target for Mirana at any stage of the game.

* 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.

* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.

* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.

* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.

* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.

* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, Lina, Rubick, etc.

* Early game gankers can make life very difficult for a Sniper if he keeps being caught: Ursa, Pudge, Earth Spirit.

* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, Enchantress.

* 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.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* 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.

* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.

* Range-reliant heroes: Sniper, Drow Ranger

* 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.

* Sniper's low mobility and lack of defensive abilities make him an easy gank target for the entire game, especially if Blink Dagger is picked up.

* 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.

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

* 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 and Repel which grants a massive strength boost.

* Pangolier can easily get close to Sniper with Swashbuckle and Rolling Thunder, negating Sniper's range advantage.
* Lucky Shot disarms Sniper and leaves him unable to effectively fight back.

* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.

* Past the early game, Sniper is an easy target for Sven to jump on with Aghanim's Scepter upgraded Storm Hammer, Blink Dagger, Silver Edge or Harpoon, common items on Sven.
* Sven's high armor and health pool makes it difficult for Sniper to focus, as his main source of damage is his right click, especially if Sven uses Warcry.
* Sniper is very squishy, and will not stand a chance against Sven head on.

* 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

* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor

* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.

* Squishy core heroes (Shadow Fiend, Sniper, etc)

* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful 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.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.

* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.

* Sniper's Take Aim can be wasted with either Muerta's Pierce the Veil or a well aimed Dead Shot.
* Dead Shot can displace Sniper from safe spots into the offensive range of Muerta's team, leading to potential kills on Sniper.
* Sniper relies heavily on his basic attacks, which is useless against Pierce the Veil.

* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.

* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.

* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when Shrapnel is on cooldown.

* 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 or to surprise Sniper during ganks. Aghanim's Scepter upgraded Infest can also allow Lifestealer to disarm Sniper and attack him from inside.
