Spectre
[wiki] rating: 2.0 (winrate: 53% pickrate: 20%)Broodmother
[wiki] rating: 1.6 (winrate: 57% pickrate: 2%)Sniper
* Sniper is completely helpless against Incapacitating Bite, and can be seriously damaged by Spiderlings in lane.
Oracle
* Oracle cannot easily deal with swarms of units, making him weak against heroes like 
Phantom Lancer or 
Broodmother.
Phantom Lancer
[wiki] rating: 1.6 (winrate: 44% pickrate: 4%)Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as 
Timbersaw, or those who can dispel them, such as Phantom Lancer, can kill Oracle unhindered.
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.
Axe
[wiki] rating: 1.4 (winrate: 50% pickrate: 10%)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.
Oracle
* False Promise will not save an ally from Culling Blade if their health is low enough.
* Fate's Edict, offensively or defensively, does little to protect Oracle's allies from the majority of Axe's damage.
Sniper
* Ranged heroes that can easily harass Axe: 
Drow Ranger, 
Sniper, 
Lion.
Anti-Mage
[wiki] rating: 1.2 (winrate: 50% pickrate: 15%)Oracle
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and 
Leshrac.
Additional:
* Oracle has minimal damage potential against Anti-Mage due to 
Counterspell, and may even have some ability damage reflected at himself.
* Anti-Mage can easily overwhelm Oracle with 
Mana Break and 
Mana Void.
* 
Blink allows Anti-Mage to easily chase and take advantage of Oracle's low mobility.
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.
Templar Assassin
[wiki] rating: 1.2 (winrate: 49% pickrate: 6%)Sniper
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: Lich, 
Lina, Sniper, 
Outworld Devourer 
Zeus
Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, 
Templar Assassin's 
Refraction and 
Visage's 
Gravekeeper's Cloak can absorb his burst damage.
Bloodseeker
[wiki] rating: 1.0 (winrate: 55% pickrate: 5%)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.
Clockwerk
[wiki] rating: 1.0 (winrate: 52% pickrate: 10%)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.
Arc Warden
[wiki] rating: 1.0 (winrate: 51% pickrate: 6%)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.
Viper
[wiki] rating: 1.0 (winrate: 51% pickrate: 8%)Sniper
* 
Nethertoxin breaks Sniper's passives.
* 
Viper Strike together with 
Poison Attack can slow Sniper and tears through his low health and mobility.
Faceless Void
[wiki] rating: 1.0 (winrate: 51% pickrate: 18%)Oracle
* 
Time Walk and 
Backtrack allow Faceless Void to easily negate Oracle's burst damage.
* 
Time Dilation is effective against Oracle's low-cooldown spells. Although dispellable with Fortune's End, it can still catch Oracle off guard if Fortune's End is on cooldown.
Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, 
Luna, Sniper, 
Terrorblade.
Oracle
* Any hero that can nullify effects of Chronosphere: (
Omniknight, 
Keeper of the Light with 
Aghanim's Scepter during daytime, 
Winter Wyvern), banishing him or Faceless Void (Outworld Devourer, 
Shadow Demon, Earth Spirit with Aghanim's Scepter) or protecting him in other ways (
Dazzle, Oracle, 
Abaddon) can greatly limit Chronosphere's potential.
Nyx Assassin
[wiki] rating: 1.0 (winrate: 51% pickrate: 3%)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.
Spirit Breaker
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)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.
Riki
[wiki] rating: 1.0 (winrate: 50% pickrate: 5%)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.
Invoker
[wiki] rating: 1.0 (winrate: 49% pickrate: 20%)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.
Terrorblade
[wiki] rating: 1.0 (winrate: 49% pickrate: 6%)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.
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.
* Warlus Punch damage can easily kill Sniper's low health instantly.
Storm Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 11%)Sniper
* 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.
Additional:
* Storm Spirit can close the distance towards Sniper very easily with his ultimate 
Ball Lightning.
Lifestealer
[wiki] rating: 1.0 (winrate: 49% pickrate: 11%)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.
Naga Siren
[wiki] rating: 1.0 (winrate: 48% pickrate: 1%)Sniper
* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Shadow Demon
[wiki] rating: 1.0 (winrate: 48% pickrate: 2%)Oracle
* 
Disruption can protect Shadow Demon's allies from Fortune's End, preserving healing or buffs. It can also catch Oracle's allies, allowing 
Shadow Poison and 
Soul Catcher to be used without being dispelled.
* 
Demonic Purge prevents over-time healing during False Promise, such as Purifying Flames and 
Urn of Shadows. If he has Aghanim's Scepter, this issue can persist for longer or on multiple allies.
* It will not, however, prevent healing from instant abilities, items, or auras, making 
Mekansm a good choice against him.
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.
Oracle
* Heroes who can dispel will be able to remove Shadow Poison before Shadow Demon can build up a big stack, or remove Soul Catcher's debuff to instantly bring the health of affected heroes back to a considerable amount: Abaddon, 
Slark, 
Legion Commander, Oracle.
Centaur Warrunner
[wiki] rating: 1.0 (winrate: 48% 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).
Weaver
[wiki] rating: 1.0 (winrate: 48% pickrate: 4%)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.
Pudge
[wiki] rating: 1.0 (winrate: 47% pickrate: 22%)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.
Puck
[wiki] rating: 1.0 (winrate: 47% pickrate: 5%)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.
Morphling
[wiki] rating: 1.0 (winrate: 47% pickrate: 12%)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.
Slark
[wiki] rating: 1.0 (winrate: 46% pickrate: 10%)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.
Bristleback
[wiki] rating: 1.0 (winrate: 44% pickrate: 4%)Oracle
* Fortune's End cannot dispel 
Warpath stacks on Bristleback or 
Quill Spray stacks on allies.
* 
Bristleback can heavily reduce Oracle's damage output. With it, Oracle may accidentally heal Bristleback with Purifying Flames, especially if Bristleback has bonus magic resistance.
Clinkz
[wiki] rating: 0.6 (winrate: 56% pickrate: 9%)Oracle
* Heroes who can take advantage of Oracle's low mobility or catch him out of position, such as 
Clinkz and Anti-Mage, can easily pick him off.
Night Stalker
[wiki] rating: 0.6 (winrate: 53% pickrate: 6%)Oracle
* Heroes with long disables, like Lion, 
Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Vengeful Spirit
[wiki] rating: 0.6 (winrate: 52% pickrate: 8%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit
Treant Protector
[wiki] rating: 0.6 (winrate: 51% pickrate: 7%)Sniper
* Clinkz, Sniper, 
Lone Druid, Troll Warlord, Legion Commander, 
Wraith King and others are some of the Heroes that bases themselves on attacks with little or no spell power, suffering in the grassy hands of Overgrowth.
Elder Titan
[wiki] rating: 0.6 (winrate: 51% pickrate: 2%)Oracle
* 
Elder Titan's 
Echo Stomp can turn into a 5 second stun on an ally under the effect of False Promise, as it delays all damage and makes it impossible to break the damage threshold of Echo Stomp.
Windranger
[wiki] rating: 0.6 (winrate: 49% pickrate: 19%)Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, 
Monkey King, 
Sven.
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.
Timbersaw
[wiki] rating: 0.6 (winrate: 49% pickrate: 5%)Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as Timbersaw, or those who can dispel them, such as Phantom Lancer, can kill Oracle unhindered.
Legion Commander
[wiki] rating: 0.6 (winrate: 49% pickrate: 14%)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.
Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Oracle
* 
Fate's Edict prevents Legion Commander from attacking for a few seconds, potentially saving Oracle's ally.
* 
Fortune's End dispels Press the Attack's healing and attack speed buff, as well as the movement speed bonus from Overwhelming Odds.
* 
False Promise protects allies and prevents Legion Commander from winning Duels and gaining bonus damage.
Additional:
* Provided that the enemy team does not have an 
Axe, Oracle can guarantee that his ally survives for the duration of the Duel with False Promise and has decent nuke potential to help ally to win a Duel. He can also disarm Legion Commander with Fate's Edict.
* Oracle can dispel enemy buffs like 
Overwhelming Odds and 
Press the Attack with Fortune's End.
Sand King
[wiki] rating: 0.6 (winrate: 48% pickrate: 7%)Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: 
Phantom Assassin, Clinkz, Sniper, 
Enchantress,...
Queen of Pain
[wiki] rating: 0.6 (winrate: 48% pickrate: 10%)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.
Lycan
[wiki] rating: 0.6 (winrate: 47% pickrate: 1%)Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Nature's Prophet
[wiki] rating: 0.6 (winrate: 45% 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.
Bounty Hunter
[wiki] rating: 0.4 (winrate: 50% pickrate: 4%)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.
Oracle
* Oracle with Fortune's End and False Promise
* Heroes that can remove the Track debuff with their skills:
* Abaddon with 
Aphotic Shield and 
Borrowed Time
* 
Huskar with 
Life Break
* 
Juggernaut with 
Blade Fury
* Legion Commander with Press the Attack
* 
Lifestealer with Rage and Infest
* 
Naga Siren with 
Mirror Image
* Omniknight with 
Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with 
Dark Pact
* 
Ursa with 
Enrage
* 
Weaver with 
Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Phantom Assassin
[wiki] rating: 0.4 (winrate: 48% pickrate: 22%)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.
Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a 
Black King Bar.
Dark Seer
[wiki] rating: -2.0 (winrate: 50% pickrate: 2%)Oracle
* Fortune's End can dispel 
Ion Shell, which cripples Dark Seer economy since it's his most efficient tool for farming.
* Fortune's End can dispel 
Surge, effectively slowing his movement speed making him vulnerable to ganks or skirmishes.
Additional:
* Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
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.
Troll Warlord
[wiki] rating: -1.6 (winrate: 48% pickrate: 4%)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.
Oracle
* Fate's Edict can disarm Troll, rendering him useless in a teamfight, especially if he has already used Battle Trance.
* Fortune's End and 
Purifying Flames can provide ample magic damage to help burst down Troll Warlord quickly in the early to mid game.
* False Promise can save an ally from Troll Warlord's initiation, forcing him to switch targets and lose his Fervor stacks, or waste time during Battle Trance.
Witch Doctor
[wiki] rating: -1.6 (winrate: 48% pickrate: 12%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: 
Witch Doctor, 
Crystal Maiden, 
Shadow Shaman, 
Pugna
Oracle
* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with Fate's Edict and Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with False Promise.
Jakiro
[wiki] rating: -1.6 (winrate: 49% pickrate: 11%)Sniper
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, Sniper, 
Tinker, 
Windranger.
Oracle
* Fate's Edict allowed Oracle to make allies spell immune, allowing him to save allies from Jakiro's spells.
* Fate's Edict can be cast onto Jakiro to disarm him and prevent him from pushing with his Liquid Fire.
* False Promise allows Oracle to free allies from Jakiro's Ice Path.
Pugna
[wiki] rating: -1.6 (winrate: 51% pickrate: 6%)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.
Oracle
* Most of Pugna's damage is magical, which can get blocked by Fate's Edict's 100% magic resistance.
* Oracle has two abilities that apply a dispel, which can easily remove Decrepify on his ally or Oracle.
* Oracle has a very long Attack Range and a very low Base Attack Time, which enables him to take down Nether Ward swiftly from long distance.
Razor
[wiki] rating: -1.6 (winrate: 53% pickrate: 1%)Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
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.
Wraith King
[wiki] rating: -1.2 (winrate: 47% pickrate: 4%)Oracle
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, Oracle.
Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Venomancer
[wiki] rating: -1.2 (winrate: 50% pickrate: 6%)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.
Oracle
* Fortune's End and False Promise easily dispel many crippling debuffs, such as 
Venomancer's 
Venomous Gale, or 
Skywrath Mage's 
Ancient Seal.
Additional:
* Fortune's End can dispel Venomous Gale and Poison Sting from allies.
* Fate's Edict grants 100% magic resistance to target, inhibiting the damage from Venomancer abilities.
Crystal Maiden
[wiki] rating: -1.2 (winrate: 51% pickrate: 13%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Sven
[wiki] rating: -1.2 (winrate: 51% pickrate: 14%)Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a Black King Bar.
Sniper
* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Grimstroke
[wiki] rating: -1.0 (winrate: 45% pickrate: 8%)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.
Kunkka
[wiki] rating: -1.0 (winrate: 46% pickrate: 5%)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.
Outworld Devourer
[wiki] rating: -1.0 (winrate: 46% pickrate: 3%)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.
Medusa
[wiki] rating: -1.0 (winrate: 47% pickrate: 2%)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.
Rubick
[wiki] rating: -1.0 (winrate: 47% pickrate: 19%)Oracle
* Oracle's high magic damage output can easily take down Rubick's low health pool.
* Because Oracle likes to combine his spells together, the only good 
Spell Steal target he gives is False Promise. This scenario can be avoided by shift queueing Fortune's End and casting it immediately, as it has no cast point, or by staying in the back line of fights if out of mana.
* As a position based hero, Rubick will have a very hard time against Fortune's End due to its absurd range and very long root duration.
Shadow Fiend
[wiki] rating: -1.0 (winrate: 47% pickrate: 15%)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.
Techies
[wiki] rating: -1.0 (winrate: 48% pickrate: 6%)Oracle
* Since Techies' skills are all magical damage, casting Fate's Edict immediately upon hearing the warning sound from 
Proximity Mines and 
Blast Off! can render Oracle or an ally immune to the burst damage from these skills.
* If timed correctly, 
Remote Mines can also be countered using the same technique.
Additional:
* Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage and his Fortune's End dispels Stasis Trap root.
Silencer
[wiki] rating: -1.0 (winrate: 49% pickrate: 6%)Oracle
* Oracle's reliance on spamming his spells can be easily hindered by Silencer's Arcane Curse.
* Last Word and Global Silence negates Oracle's attempt to save his allies with his spells.
* Fate's Edict is useless against Glaives of Wisdom's pure damage.
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.
Oracle
* Fortune's End can nullify 
Arcane Curse, 
Last Word, and Global Silence, if cast at the right time with the right targets.
* Fate's Edict can prevent Silencer from attacking, which he relies on with 
Glaives of Wisdom, for a lot of his damage.
Dark Willow
[wiki] rating: -1.0 (winrate: 49% pickrate: 6%)Oracle
* Fortune's End can easily dispel 
Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate 
Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from 
Shadow Realm.
* Fortune's End can dispel the fear effect from 
Terrorize, and it can remove the root from 
Bramble Maze if you're quick enough. Be mindful that Fortune's End only dispels your allies' debuffs on the primary target.
Additional:
* Fortune's End not being disjointable is almost an ensured disable if Dark Willow tries to escape with Shadow Realm. Dispels Cursed Crown and Terrorize.
* Fate's Edict negates all her magic damage in case she catches a single hero.
* False Promise's strong dispel removes Dark Willow's disables.
Earthshaker
[wiki] rating: -1.0 (winrate: 50% pickrate: 10%)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.
Phoenix
[wiki] rating: -1.0 (winrate: 50% pickrate: 11%)Oracle
* Phoenix does significant magic damage over time which can either be dispelled or negated by Fate's Edict.
* Since Phoenix sacrifices some of his health to cast abilities it makes him very vulnerable to Oracle's burst potential
Magnus
[wiki] rating: -1.0 (winrate: 50% pickrate: 14%)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.
Oracle
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, 
Enigma, Luna, Naga Siren, 
Mars, 
Jakiro, Venomancer, Elder Titan, 
Faceless Void, 
Rubick, Keeper of the Light, Pugna, 
Invoker, 
Spectre, 
Alchemist, 
Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, 
Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, 
Sand King.
Luna
[wiki] rating: -1.0 (winrate: 50% pickrate: 4%)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.
Necrophos
[wiki] rating: -1.0 (winrate: 51% pickrate: 6%)Oracle
* Fortune's End can dispel 
Ghost Shroud, rending Necrophos vulnerable to physical damage. Also it's worth noting that Necrophos takes additional magic damage when in Ethereal state, which makes Purifying Flames a powerful nuke against him.
* Fate's Edict fully negates the damage from 
Reaper's Scythe, which its own delayed animation makes it relatively easy to predict and nullify.
Additional:
* During the laning stage, Oracle's Purifying Flames nullifies any damage that Heartstopper Aura might inflict.
* Fate's Edict and False Promise can protect an ally from Reaper's Scythe.
* Oracle can dispel Ghost Shroud with Fortune's End.
Ancient Apparition
[wiki] rating: -1.0 (winrate: 51% pickrate: 6%)Oracle
* 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.
Additional:
* 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 because of the delayed effect.
* Purifying Flames also 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.
* Fate's Edict is good against all of Ancient Apparition's abilities at all stages of the game.
* Fortune's End can dispel Cold Feet from allies.
Beastmaster
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Oracle
* False Promise effectively nullifies Primal Roar's single-target initiation on allies.
* Purifying Flames kills Beastmaster's Hawk instantly and Boar with two casts.
Ogre Magi
[wiki] rating: -1.0 (winrate: 52% pickrate: 18%)Oracle
* Fate's Edict gives full immunity from Ogre Magi's mostly magical damage.
* Fortune's End can dispel Ignite (when used on allies) and Bloodlust (when used on enemies).
* False Promise can dispel Ignite and Fireblast.
Leshrac
[wiki] rating: -1.0 (winrate: 52% pickrate: 6%)Oracle
* Oracle's Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* Fortune's End can stop Leshrac from chasing opponents or running away.
Enigma
[wiki] rating: -1.0 (winrate: 53% pickrate: 2%)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.
Undying
[wiki] rating: -1.0 (winrate: 53% pickrate: 11%)Sniper
* Sniper can easily destroy 
Tombstone from long range.
Drow Ranger
[wiki] rating: -1.0 (winrate: 53% pickrate: 16%)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.
Keeper of the Light
[wiki] rating: -0.6 (winrate: 44% pickrate: 2%)Oracle
* Heroes with dispels: Legion Commander, Oracle, Slark
Tiny
[wiki] rating: -0.6 (winrate: 47% pickrate: 14%)Sniper
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Monkey King
[wiki] rating: -0.6 (winrate: 47% pickrate: 8%)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
Doom
[wiki] rating: -0.6 (winrate: 48% pickrate: 6%)Oracle
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, 
Warlock.
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.
Oracle
* Heroes with the ability to heal allies, or those with good defensive abilities: (Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, (Abaddon, etc.
Skywrath Mage
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Shadow Shaman
[wiki] rating: -0.6 (winrate: 50% pickrate: 7%)Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Void Spirit
[wiki] rating: -0.6 (winrate: 50% pickrate: 12%)Oracle
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Juggernaut
[wiki] rating: -0.6 (winrate: 50% pickrate: 19%)Oracle
* Heroes with abilities that can save are also effective such as Shadow Demon, Dazzle, Oracle, 
Bane, Pugna, 
Tusk, Winter Wyvern, Io, Underlord, Treant Protector and Keeper of the Light.
Tidehunter
[wiki] rating: -0.6 (winrate: 51% pickrate: 6%)Sniper

Mirana
[wiki] rating: -0.6 (winrate: 52% pickrate: 14%)Oracle
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Devourer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Underlord
[wiki] rating: -0.6 (winrate: 54% pickrate: 10%)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.
Disruptor
[wiki] rating: -0.4 (winrate: 48% pickrate: 10%)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.
Batrider
[wiki] rating: -0.4 (winrate: 49% pickrate: 2%)Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit
Oracle
* False Promise dispels Flaming Lasso.
* Fortune's End can root Batrider after he uses Flaming Lasso. It can also dispel Sticky Napalm and Flamebreak.
* Fate's Edict when used on a Lasso'd target will leave them immune to magical damage, making it difficult to burst them quickly before the Lasso ends.
Io
[wiki] rating: -0.4 (winrate: 50% pickrate: 6%)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.
Enchantress
[wiki] rating: 0.0 (winrate: 45% pickrate: 2%)Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Lion
[wiki] rating: 0.0 (winrate: 47% pickrate: 14%)Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Oracle
* Lion is extremely dependent on his abilities. Silences like 
Silencer's Last Word, magic resistance like Oracle's Fate's Edict, and dispels like Legion Commander's Press the Attack all make his abilities less effective.
Ember Spirit
[wiki] rating: 0.0 (winrate: 47% pickrate: 9%)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.
Oracle
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel 
Flame Guard on Ember Spirit and Searing Chains on allies.
* When Ember Spirit is affected by Fortune's End, his 
Fire Remnants move at 0 movement speed.
* Disarming him with Fate's Edict does affect Ember's 
Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
Pangolier
[wiki] rating: 0.0 (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.
Sniper
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, Arc Warden
Mars
[wiki] rating: 0.0 (winrate: 48% pickrate: 19%)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.

Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Bane
[wiki] rating: 0.0 (winrate: 51% pickrate: 5%)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.
Oracle
* Heroes with dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight
Slardar
[wiki] rating: 0.0 (winrate: 51% pickrate: 13%)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.
Oracle
* Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
Visage
[wiki] rating: 0.0 (winrate: 51% pickrate: 1%)Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's Refraction and Visage's Gravekeeper's Cloak can absorb his burst damage.
Sniper
* Heroes with long ranged attacks or abilities can harass Visage from afar like Phoenix and Sniper.
Omniknight
[wiki] rating: 0.0 (winrate: 53% pickrate: 2%)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.
Oracle
* Fortune's End's AoE dispel will remove Guardian Angel.
Additional:
* With Fortune's End, Oracle can dispel Guardian Angel in an area of effect.
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.
Oracle
* Oracle's burst damage is ineffective against
Dispersion.
* Disarm provided by Fate's Edict is not as significant debilitation for Spectre as it might be for other carries since She can do damage even without landing attacks.
