Spectre
[wiki] rating: 2.0 (winrate: 47% pickrate: 3%)Anti-Mage
[wiki] rating: 1.6 (winrate: 49% pickrate: 13%)Ancient Apparition
* Anti-Mage easily Blinks out of 
Cold Feet's freeze radius.
* Ancient Apparition lacks mobility, thus making him fall easily to Mana Void.
Additional:
* 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.
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.
Clinkz
[wiki] rating: 1.2 (winrate: 53% pickrate: 4%)Ancient Apparition
* 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.
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: 1.2 (winrate: 52% pickrate: 5%)Ancient Apparition
* 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.
Oracle
* Heroes with long disables, like 
Lion, Night Stalker, or 
Legion Commander, can prevent Oracle from using spells or items.
Templar Assassin
[wiki] rating: 1.2 (winrate: 51% pickrate: 5%)Ancient Apparition
* 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
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.
Lycan
[wiki] rating: 1.0 (winrate: 54% pickrate: 3%)Ancient Apparition
* 
Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has many fast summons, both his wolves from 
Summon Wolves and from the frequently built 
Necronomicon, all of which can do heavy damage to Ancient Apparition due to his immobility and low armor.
Phantom Lancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 10%)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.
Ancient Apparition
* 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.
Ancient Apparition
* Ancient Apparition's 
Ice Blast will only debuff Phantom Lancer and not his illusions.
* Heroes with undispellable debuffs will help identify the real Phantom Lancer through visual effects or debuff indicators, provided that it was cast on the real Phantom Lancer to begin with:
* 
Doom's 
Doom marks Phantom Lancer with a highly visible effect, and also silences him.
* 
Bloodseeker's 
Rupture shows a clear red trail effect on the real Phantom Lancer.
* Ancient Apparition's Ice Blast will only debuff Phantom Lancer and not his illusions.
* Grimstroke's 
Soulbind is undispellable.
* 
Shadow Demon's 
Demonic Purge is undispellable.
* 
Monkey King's 
Jingu Mastery is undispellable and puts a big yellow Mark over his head.
Weaver
[wiki] rating: 1.0 (winrate: 51% pickrate: 13%)Ancient Apparition
* 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.
Additional:
* 
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.
Brewmaster
[wiki] rating: 1.0 (winrate: 50% pickrate: 1%)Ancient Apparition
* 
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.
Storm Spirit
[wiki] rating: 1.0 (winrate: 49% pickrate: 12%)Ancient Apparition
* 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.
Axe
[wiki] rating: 1.0 (winrate: 47% pickrate: 8%)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.
Viper
[wiki] rating: 1.0 (winrate: 47% pickrate: 6%)Ancient Apparition
* 
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.
Terrorblade
[wiki] rating: 1.0 (winrate: 46% pickrate: 4%)Ancient Apparition
* Sunder is not affected by Ice Blast and will still swap health with any target as usual.
Additional:
* 
Sunder allows Terrorblade (or an ally) to regain HP while affected by Ice Blast.
* Terrorblade often buys Manta Style which can dispel Cold Feet
Lina
[wiki] rating: 1.0 (winrate: 46% pickrate: 9%)Ancient Apparition
* 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.
Visage
[wiki] rating: 0.6 (winrate: 54% 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.
Nyx Assassin
[wiki] rating: 0.6 (winrate: 54% pickrate: 7%)Ancient Apparition
* 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.
Shadow Shaman
[wiki] rating: 0.6 (winrate: 52% pickrate: 16%)Ancient Apparition
* 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.
Windranger
[wiki] rating: 0.6 (winrate: 51% pickrate: 16%)Ancient Apparition
* 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.
Spirit Breaker
[wiki] rating: 0.6 (winrate: 51% pickrate: 8%)Ancient Apparition
* 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
[wiki] rating: 0.6 (winrate: 50% pickrate: 16%)Ancient Apparition
* 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.
Lion
[wiki] rating: 0.6 (winrate: 50% pickrate: 17%)Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Ancient Apparition
* Finger of Death can instantly shred many targets especially fragile Heroes like 
Keeper of the Light, Ancient Apparition, or Bounty Hunter.
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.
Elder Titan
[wiki] rating: 0.6 (winrate: 49% pickrate: 1%)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.
Silencer
[wiki] rating: 0.6 (winrate: 49% pickrate: 5%)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.
Ancient Apparition
* 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.
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.
Riki
[wiki] rating: 0.6 (winrate: 48% pickrate: 5%)Ancient Apparition
* 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.
Queen of Pain
[wiki] rating: 0.6 (winrate: 47% pickrate: 9%)Ancient Apparition
* 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
[wiki] rating: 0.6 (winrate: 46% pickrate: 1%)Ancient Apparition
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, Skywrath Mage etc.
Tiny
[wiki] rating: 0.6 (winrate: 45% pickrate: 5%)Ancient Apparition
* Squishy heroes, usually supports, like 
Io, Ancient Apparition, Keeper of the Light etc can die instantly from Tiny's magic burst.
Mirana
[wiki] rating: 0.4 (winrate: 51% pickrate: 16%)Ancient Apparition
* 
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.
Oracle
* Heroes that can protect or dispel stunned allies such as Legion Commander, 
Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Void Spirit
[wiki] rating: 0.4 (winrate: 50% pickrate: 13%)Ancient Apparition
* 
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.
Oracle
* Heroes that can purge his slow and disables are very difficult to go on and their team: 
Abaddon, Oracle.
Shadow Demon
[wiki] rating: 0.4 (winrate: 47% 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.
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.
Bristleback
[wiki] rating: 0.4 (winrate: 46% pickrate: 8%)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.
Ancient Apparition
* Heroes that withstand damage like Timbersaw, 
Bristleback, 
Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Faceless Void
[wiki] rating: 0.4 (winrate: 41% pickrate: 3%)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.
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 Destroyer, Shadow Demon, 
Earth Spirit with Aghanim's Scepter) or protecting him in other ways (
Dazzle, Oracle, Abaddon) can greatly limit Chronosphere's potential.
Necrophos
[wiki] rating: -2.0 (winrate: 50% pickrate: 3%)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
* Ice Blast completely nullifies any healing, making Necrophos unable to stay in a teamfight to sustain his teammates (and himself) or deal gradual damage to the enemy, else he be faced with a quick death if focused on.
Witch Doctor
[wiki] rating: -1.6 (winrate: 47% pickrate: 13%)Ancient Apparition
* Heroes like Slark, Witch Doctor and others also tend to suffer in Ice Blast's heal denial.
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.
Omniknight
[wiki] rating: -1.6 (winrate: 47% pickrate: 1%)Ancient Apparition
* Heroes with large magical AoE damage will fare well against Omniknight: Lich, Ancient Apparition, 
Jakiro, 
Disruptor
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.
Snapfire
[wiki] rating: -1.0 (winrate: 46% pickrate: 5%)Ancient Apparition
* Ice Blast, Cold Feet, and Ice Vortex are easier to land on Snapfire while she channels her 
Mortimer Kisses.
Additional:
* Snapfire is vulnerable while she is casting 
Mortimer Kisses making her an easy target for the effects of Cold Feet and Ice Blast.
Rubick
[wiki] rating: -1.0 (winrate: 46% pickrate: 16%)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.
Morphling
[wiki] rating: -1.0 (winrate: 46% pickrate: 12%)Ancient Apparition
* Ice Blast stops Attribute Shift (Strength Gain) from recovering additional health, and using it will even bring Morphling closer to the shatter threshold.
* In lane, Ice Vortex slows Morphling's already poor movement speed to a crawl; this, coupled with the amplification of magic damage, can set up an early kill on Morphling if Ancient Apparition has a suitable lane partner.
Ember Spirit
[wiki] rating: -1.0 (winrate: 47% pickrate: 9%)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.
Legion Commander
[wiki] rating: -1.0 (winrate: 47% pickrate: 11%)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.
Ancient Apparition
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: 
Nature's Prophet, Ancient Apparition, 
Zeus, Invoker, 
Treant Protector
Dragon Knight
[wiki] rating: -1.0 (winrate: 48% pickrate: 4%)Ancient Apparition
* Cold Feet and Ice Vortex both hinder Dragon Knight's movement greatly during teamfights.
* Ice Blast ignores Dragon Knight's armor and kills him prematurely.
Dazzle
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Ancient Apparition
* Ice Blast negates healing from Shadow Wave, and lasts longer than Shallow Grave.
Additional:
* 
Shallow Grave prevents Ice Blast's shatter for up to 5 seconds, but can mostly only delay it as Ice Blast's debuff lasts 10 seconds and prevents 
Shadow Wave from healing them.
Slark
[wiki] rating: -1.0 (winrate: 48% pickrate: 13%)Ancient Apparition
* Ice Blast stops Shadow Dance's passive health regeneration, even when Slark is not in vision.
Techies
[wiki] rating: -1.0 (winrate: 48% pickrate: 8%)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.
Lifestealer
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Ancient Apparition
* Ice Blast prevents Lifestealer from lifestealing and healing with Infest in fights.
Winter Wyvern
[wiki] rating: -1.0 (winrate: 49% pickrate: 7%)Ancient Apparition
* 
Cold Embrace makes its target immovable, allowing Ancient Apparition to easily land Ice Blast, or a Cold Feet stun
* Ice Blast also negates healing from Cold Embrace
Additional:
* Ice Blast disables the healing component of Cold Embrace, making it essentially a 4 second stun on an ally and a perfect setup for Ice Blast.
* If Cold Feet is cast on an Allied hero affected by Cold Embrace, it will almost guarantee the Ally comes out stunned.
Slardar
[wiki] rating: -1.0 (winrate: 50% pickrate: 5%)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.
Warlock
[wiki] rating: -1.0 (winrate: 50% pickrate: 4%)Ancient Apparition
* Ice Blast nullifies the healing from {U:Warlock Golem} and 
Shadow Word.
* Cold Feet stuns Warlock if he chooses to continue channeling 
Upheaval.
Jakiro
[wiki] rating: -1.0 (winrate: 50% pickrate: 9%)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.
Ogre Magi
[wiki] rating: -1.0 (winrate: 51% pickrate: 14%)Oracle

* False Promise can dispel Ignite and Fireblast.
Leshrac
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)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.
Io
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Ancient Apparition
* Ice Blast prevents Io from healing the target.
Additional:
* Ice Blast prevents Io from healing an ally with 
Tether and prevents healing from 
Overcharge
* Io is a common Mekansm builder which is useless if he is affected by Ice Blast.
Dark Seer
[wiki] rating: -1.0 (winrate: 51% pickrate: 3%)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.
Death Prophet
[wiki] rating: -1.0 (winrate: 51% pickrate: 10%)Ancient Apparition
* Cold Feet's debuff affects Death Prophet even while she's affected by 
Eul's Scepter of Divinity.
* Ice Vortex lowers her magic resistance and her kiting potential.
* Ice Blast prevents Death Prophet from gaining health from Spirit Siphon and Exorcism.
Additional:
* Ice Blast prevents Death Prophet from gaining health from 
Spirit Siphon and 
Exorcism.
Abaddon
[wiki] rating: -1.0 (winrate: 52% pickrate: 5%)Ancient Apparition
* 
Chilling Touch's damage component can easily overwhelm Aphotic Shield's damage block.
* Ice Blast's nullifies Abaddon healing from Borrowed Time and Mist Coil and it is not dispelled by Aphotic Shield.
Additional:
* Ice Blast nullifies 
Borrowed Time's and 
Mist Coil's healing.
Troll Warlord
[wiki] rating: -1.0 (winrate: 52% pickrate: 12%)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.
Chen
[wiki] rating: -1.0 (winrate: 52% pickrate: 0%)Ancient Apparition
* Ice Blast prevents healing from Hand of God.
Additional:
* Ice Blast prevents 
Divine Favor and 
Hand of God from healing his allies or himself.
Dark Willow
[wiki] rating: -1.0 (winrate: 52% pickrate: 7%)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.
Huskar
[wiki] rating: -1.0 (winrate: 52% pickrate: 3%)Ancient Apparition
* Ice Blast prevents Huskar from healing, regeneration, health gained from activating an 
Armlet of Mordiggian and will kill him when his health dips below a threshold. This makes it very dangerous for him to use his abilities.
Additional:
* Ice Blast prevents Huskar from healing with 
Berserker's Blood and negates any lifesteal, making him significantly weaker in battle.
* 
Burning Spear and 
Life Break cost Huskar his own health, killing him under the effects from Ice Blast.
* Huskar often builds Armlet of Mordiggian which can be deadly during Ice Blast.
Pugna
[wiki] rating: -1.0 (winrate: 53% pickrate: 4%)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.
Beastmaster
[wiki] rating: -1.0 (winrate: 53% pickrate: 6%)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.
Alchemist
[wiki] rating: -1.0 (winrate: 53% pickrate: 14%)Ancient Apparition
* Ice Blast cancels out Chemical Rage's rapid health regeneration. It can also take advantage of Alchemist's Armlet of Mordiggian toggling, as it will make HP drain insanely fast, essentially killing the bearer in no time.
Additional:
* Ice Blast nullifies the health regeneration granted by 
Chemical Rage, which Alchemist greatly relies on to stay alive in battle.
* Alchemist tends to build Armlet of Mordiggian which can be deadly during Ice Blast.
Sven
[wiki] rating: -0.6 (winrate: 43% pickrate: 1%)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.
Magnus
[wiki] rating: -0.6 (winrate: 44% pickrate: 4%)Oracle
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, 
Enigma, 
Luna,

* Heroes with dispels: Legion Commander, Oracle, Slark
Enchantress
[wiki] rating: -0.6 (winrate: 46% pickrate: 1%)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.
Mars
[wiki] rating: -0.6 (winrate: 48% pickrate: 16%)Oracle
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, 
Tinker, Zeus, Oracle.
Sniper
[wiki] rating: -0.6 (winrate: 49% pickrate: 6%)Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as 
Sniper or Razor.
Crystal Maiden
[wiki] rating: -0.6 (winrate: 49% pickrate: 14%)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.
Venomancer
[wiki] rating: -0.6 (winrate: 50% pickrate: 5%)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.
Phoenix
[wiki] rating: -0.6 (winrate: 50% pickrate: 9%)Ancient Apparition
* Supernova with or without Aghanim's Scepter allows to save ally or himself through Ice Blast.
* Icarus Dive quickly escapes from Cold Feet.
Additional:
* 
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.
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
Ancient Apparition
* Since all of Phoenix's abilities (except for Supernova) have health costs, heroes like Ancient Apparition or Necrophos can turn Phoenix's abilities against it. However, Supernova does completely protect Phoenix from Ice Blast.
Wraith King
[wiki] rating: -0.6 (winrate: 51% pickrate: 17%)Oracle
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, Oracle.
Clockwerk
[wiki] rating: -0.6 (winrate: 52% pickrate: 7%)Ancient Apparition
* Ancient Apparition's Cold Feet will freeze Clockwerk in place if he stays inside his Power Cogs. His immobility while in his cogs also makes him a very easy target to Ice Vortex and Ice Blast.
Bane
[wiki] rating: -0.6 (winrate: 54% pickrate: 3%)Oracle
* Heroes with dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight
Razor
[wiki] rating: -0.6 (winrate: 54% pickrate: 6%)Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Batrider
[wiki] rating: -0.4 (winrate: 47% pickrate: 1%)Ancient Apparition
* 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.
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.
Broodmother
[wiki] rating: -0.4 (winrate: 53% pickrate: 2%)Oracle
* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or 
Broodmother.
Ancient Apparition
* Ice Blast prevents 
Insatiable Hunger lifesteal, 
Spin Web regeneration and quickly kills spiderlings.
Doom
[wiki] rating: 0.0 (winrate: 44% pickrate: 2%)Oracle
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, Warlock.
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.
Phantom Assassin
[wiki] rating: 0.0 (winrate: 45% pickrate: 16%)Ancient Apparition
* 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.
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.
Timbersaw
[wiki] rating: 0.0 (winrate: 48% pickrate: 8%)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.
Ancient Apparition
* Heroes that withstand damage like Timbersaw, Bristleback, Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Skywrath Mage
[wiki] rating: 0.0 (winrate: 50% pickrate: 6%)Ancient Apparition
* 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.
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.
Juggernaut
[wiki] rating: 0.0 (winrate: 52% pickrate: 19%)Ancient Apparition
* 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.
Oracle
* Heroes with abilities that can save teammates are also effective such as Shadow Demon, Dazzle, Oracle, 
Bane, Pugna, 
Tusk, Winter Wyvern, Io, 
Underlord, Treant Protector and Keeper of the Light.
Bounty Hunter
[wiki] rating: 0.0 (winrate: 54% pickrate: 10%)Ancient Apparition

Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with 
Blade Fury
* Legion Commander with Press the Attack
* 
Lifestealer with 
Rage and 
Infest

Mirror Image

Heavenly Grace

Dark Pact
* 
Ursa with 
Enrage
* 
Weaver with Time Lapse
* Tidehunter with 
Kraken Shell when damage received reaches the threshold.
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.
Ancient Apparition
* 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.
