Visage
* Heroes with long ranged attacks or abilities can harass Visage from afar like 
Phoenix and

Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
Visage
* 
Sand King's 
Sand Storm damages familiars quickly whittling them down in health, rendering them vulnerable.
* Sand King's 
Epicenter quickly damages and destroys familiars.
Visage
* 
Centaur Warrunner's passive 
Retaliate makes it so that the familiars cannot attack him without damaging themselves over time, in turn causing them to be destroyed.
Dark Seer
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by 
Surge become futile. For what it's worth, Demonic Purge will also dispel 
Ion Shell.
Visage
* Diabolic Edict and Pulse Nova hit all units around Leshrac, making it very easy for him to kill the 
Summon Familiars.
* Diabolic Edict and Pulse Nova also deal many instances of damage, nullifying 
Gravekeeper's Cloak.

Visage to kite Leshrac, even while under the effects of 
Grave Chill.
Visage
* Phoenix's 
Supernova cannot be damaged by Familiars.

Kraken Shell and will do almost no damage to 
Tidehunter even with 
Medallion of Courage or 
Solar Crest.
* 
Anchor Smash's bonus damage has the potential to kill Familiars.

* 
Reactive Armor will quickly stack up from Familiar attacks, making Timbersaw hard to kill.
* Visage's low mobility makes it easy for 
Timbersaw to line up his abilities.
Visage
* 
Moon Glaives is very effective against Visage because not only it can easily destroy Visage's Familiars, but can also remove one instance of Gravekeeper's Cloak upon each hit to Visage, leaving him susceptible to damage.
* Once Visage's Familiars are picked off and all instances of Gravekeeper's Cloak are removed, Luna will be able to easily kill Visage with 
Eclipse.
Additional:

Dark Seer
* 
Spell Steal will easily steal all abilities from Dark Seer.
Additional:
* Spell Steal can perfect from Rubick's steal all abilities from Dark Seer. Rubick's always purchase 
Aghanim's Scepter can two stolens abilities from Dark Seer's and waiting for seconds for second stolen abilities (example: combinated Vacuum and Wall of Replica) and many different combination.
* A good positoning from Rubick's Spell Steal waiting steal abilities from Dark Seer 
Wall of Replica and illusion from Wall of Replica Dark Seer's can fighting with effect from outcome steal Wall of Replica from Rubick's.
* Combinated Rubick's steal Surge and 
Blink Dagger is very important catch from Dark Seer's and enemies.
* Rubick's 
Telekinesis can lifted up Dark Seer or enemy heroes and throw to Wall of Replica from Rubick's steal.
Dark Seer
* Dark Seer's strength lies in his high-mana cost skills. So 
Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* 
Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
Visage
* 
Scorched Earth can be used to engage Visage while removing Gravekeeper's Cloak charges.
* 
Infernal Blade will deal tremendous amounts of damage over time due to Visage's high health pool.
* 
Doom completely nullifies Gravekeeper's Cloak and prevents Visage from casting spells.
Dark Seer
* Heroes with fast movement abilities will suffer huge damage when afflicted by Rupture: 
Spirit Breaker, 
Earth Spirit, 
Dark Seer.
Additional:
* 
Rupture can deal a lot of damage to either a surged Dark Seer or his allies and prevent the target from getting into position.
Visage
* Heroes with summons and illusions can find themselves easily bested by Lina, like 
Broodmother, 
Nature's Prophet, 
Chen, 
Terrorblade, 
Naga Siren, Visage, 
Wraith King, 
Lycan, 
Phantom Lancer, 
Shadow Shaman.
Dark Seer
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as Weaver or Queen of Pain.
Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as 
Disruptor's 
Kinetic Field or 
Slark's 
Pounce.
Visage
* Jakiro's area-of-effect abilities make him strong against heroes who rely on illusions and summons: Terrorblade, Naga Siren 
Chaos Knight, Phantom Lancer, Broodmother, Nature's Prophet, Lycan, Wraith King, Visage.
Visage
* Heroes with armor reducing abilities greatly hinder Visage's defense like 
Slardar and 
Dazzle.

Kunkka, 
Magnus and 
Medusa.
Visage
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter, Kunkka, Magnus and Medusa.
Dark Seer
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: Dark Seer, 
Riki, 
Rubick.
Dark Seer
* 
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.
Additional:
* Fortune's End can dispel Ion Shell, a skill that helps Dark Seer immensely in the laning phase, as well as Surge, a move-speed buff, effectively allowing Oracle to control Dark Seer, especially in the laning phase.
Visage
* 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.
Visage
* 
Viper Strike can disable Gravekeeper's Cloak, Visage's primary defense mechanism.
* Viper can ignore Grave Chill's attack speed slow with his magic damage output.
Additional:
* Since Visage is a slow hero, 
Viper can easily kite him with 
Poison Attack and Viper Strike while successfully chipping away at Gravekeeper's Cloak.
* 
Nethertoxin removes all layers of Gravekeeper's Cloak, leaving Visage exposed.
* 
Corrosive Skin makes Viper highly resistant to Soul Assumption.
Dark Seer
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: 
Clinkz, 
Pugna, Nature's Prophet, Dark Seer, Lycan, 
Tusk
Visage
* Pangolier's high mobility allows Pangolier to escape from Visage's ganking attempt. Keep in mind that his familiars can easily interfere with your ultimate during casting time if they are able to scout your position.
* Swashbuckle quickly burn away Gravekeeper's Cloak charges.
Dark Seer
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): 
Vengeful Spirit, 
Keeper of the Light, Huskar, Dark Seer
Visage
* Phantom Lancer's illusions will quickly destroy multiple layers of Gravekeeper's Cloak.
* Visage has no mobility mechanisms, making him a prime target for 
Phantom Rush.
Dark Seer
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer, Chaos Knight, Naga Siren, Terrorblade.
Additional:
* Ion Shell helps taking down illusions quickly, making it easy to identify the real Phantom Lancer.
* Surge allows Dark Seer and his teammates to run away from Phantom Lancer, who relies on his Phantom Rush to chase enemies.
Dark Seer
* Dark Seer's 
Vacuum and Ion Shell can clear a wave of Chen's Creeps effectively.
* Surge applies haste movement and negates the slow from 
Penitence, allowing Dark Seer to easily escape from Chen and his creeps.
* Dark Seer's full combo from Dark Seer's Vacuum, Wall of Replica and 
Normal Punch from Aghanim's Scepter can often kill Chen or any of his allies before he can save them with 
Hand of God.

* Dark Seer's full combo from Dark Seer's Vacuum, Wall of Replica and Normal Punch from Aghanim's Scepter can often kill Chen or any of his allies before he can save them with Hand of God.
Visage
* Grave Chill can heavily slow down Chen and boost Visage and his familiars's attack speed and movement speed.
* Chen's 
Holy Persuasion cannot convert Visage's familiars from Summon Familiars at all, not even when upgraded with 
Aghanim's Shard that allows Chen to use it on ancient creeps as Visage's familiars are treated as creep-heroes, which could put Chen in disadvantage against Visage if his creeps die.
* Skilled Visage can buy 
Bloodthorn to prevent Chen from any chance of retaliating or saving himself with Hand of God and 
Gleipnir to clear waves of Chen's creeps and prevent them from escaping. This can get even better if Visage has access to 
Silent as the Grave ability from Aghanim's Scepter that will allow Visage and his familiars to be invisible, which they can use either to escape from Chen or to prepare a deadly surprise to him.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: 
Beastmaster, Broodmother, 
Enigma, Nature's Prophet, Visage, 
Warlock, Wraith King.
Visage
* Nature's Prophet has no innate way to deal with Gravekeeper's Cloak or kill {U:Familiar}s effectively.
* Familiars can fly over the trees created by Sprout. They can also use 
Stone Form when Nature's Prophet is trying to use Teleportation.
* Aghanim's Shard upgraded Stone Form alow allows Visage himself to stun Nature's Prophet whenever he is trying to use Teleportation.
* Aghanim's Scepter gives Visage Silent as the Grave ability, which allows him and his {U:Familiar}s to either escape from Nature's Prophet or give him a surprise attack.
Additional:
* Nature's Prophet has no natural method of dealing with Gravekeeper's Cloak and Familiars.
* Familiar's low base attack time can chip away Nature Prophet's health.
* Familiar's Stone Form destroys trees created by 
Sprout.
* Familiars can scout woods and foggy areas where Nature's Prophet is trying to use 
Teleportation.
Dark Seer
* Dark Seer can pull together Spectre's illusions with Vacuum, and Wall of Replica creates an illusion of Spectre that deals massive damage.
Visage
* Familiars will be able to chase Spectre through the trees when she uses 
Spectral Dagger, while Visage can keep blasting her with Soul Assumption.
* 
Desolate will almost never proc because Visage will always have nearby Familiars.
Dark Seer
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, Viper, 
Venomancer, Huskar, 
Ember Spirit, Dark Seer, Sand King, 
Doom, 
Dawnbreaker. However, this also means they are easily stunned.
Visage
* Even though Visage's Familiars from Summon Familiars are fragile and can be killed quickly with Nyx Assassin's high burst damage, they can deal many instances of damage quickly, minimizing the effectiveness of Spiked Carapace.
* Gravekeeper's Cloak and tanky item builds make Visage hard for Nyx to kill with his burst damage. Aghanim's Shard upgraded Gravekeeper's Cloak also allows Visage to use 
Stone Form to both recover himself and stun Nyx Assassin if he is close enough to Visage.
* Visage's long range on 
Soul Assumption and Grave Chill make him hard to escape from, and Soul Assumption's low cooldown outmatches Spiked Carapace.
Dark Seer
* With Normal Punch from Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: 
Phantom Assassin, 
Windranger, 
Hoodwink.
Visage
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Visage
* Stone Form can easily interrupt heroes with long channeling spells, like 
Crystal Maiden, 
Bane, 
Witch Doctor, or Enigma.
Visage
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, 
Meepo, Terrorblade and Phantom Lancer.
Dark Seer
* Dark Seer's Vacuum and Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require 
Ultimate Orb like 
Manta Style and 
Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with Wall of Replica and Normal Punch from Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.
Additional:
* Dark Seer's Vacuum and Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require Ultimate Orb like Manta Style and Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with Wall of Replica and Normal Punch from Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.
Visage
* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, 
Shadow Demon, Dark Seer, Nature's Prophet, 
Invoker, 
Morphling, Visage, 
Grimstroke with Aghanim's Scepter.
Visage
* Familiars can fly over the mines, rendering them safe from damage of Techies's mines. Visage can also use Familiars to check for mines on the map.
* Techies's low attack speed and damage will give them a hard time in destroying Visage's Familiars, and that can become even worse if they are affected by Grave Chill.
* Gravekeeper's Cloak allows Visage to survive Damage from Techies's mines.
Dark Seer
* Ion Shell destroys Refraction's protection stacks in short time.
* Surge ignores the massive slow from 
Psionic Trap.
Visage
* Stone Form's long stun duration may prevent Puck from using escape abilities.
* Visage frequently builds 
Rod of Atos for the root that will make Puck unable to move and use his escape abilities. Alternatively, Visage can also build Bloodthorn to prevent Puck from using his escape abilities and make him more vulnerable to damage.
Visage
* Grave Chill will make Crystal Maiden's bad movement speed even worse.
* Soul Assumption charges can easily be stacked up from Freezing Field, allowing Visage to nuke enemies multiple times throughout the fight.
* {U:Familiar}'s Stone Form can also be used to interrupt Freezing Field, even while Crystal Maiden is under the effects of 
Glimmer Cape. Crystal Maiden must purchase a 
Black King Bar, which is far more costly.
Visage
* {U:Familiar}s can spot Clockwerk, allowing Visage's allies to dodge or block Hookshot attempts.
* Familiars will not be damaged by 
Blade Mail or Clockwerk's abilities, dealing dangerous amounts of damage to him.

Hookshot attempts.

* Grave Chill can make Shadow Shaman's bad movement speed and attack speed even worse.
* Visage is also a natural Bloodthorn wielder, which allows him to silence Shadow Shaman and make him more vulnerable to damage.
Additional:
* Due to their high attack speed, Visage's Summon Familiars will destroy 
Mass Serpent Ward quickly, granting Visage massive amount of gold.
Dark Seer

Dark Seer
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer, Chaos Knight, Naga Siren, Terrorblade.

Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Additional:
* Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.
Visage

Brain Sap: Broodmother, Chaos Knight, Naga Siren, Nature's Prophet, Phantom Lancer, Terrorblade, Visage, Warlock, Wraith King.
Visage
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, 
Tiny and 
Undying have a very hard time killing Familiars.
Dark Seer
* The haste provided by Dark Seer's Surge or a {Rune:Haste} renders Lich's slows ineffective.
Visage
* Heroes with magic immune abilities can negate most of Visage's attacks like 
Pangolier and 
Lifestealer.

Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.

* Stone Form can quickly interrupt 
Dismember.
Visage
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.
Dark Seer
* Dark Seer can take great advantage of 
Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable him for Dark Seer and his teammates to take out.
Visage
* Heroes with very little to no area-of-effect abilities will struggle greatly against Broodmother: Sniper, Phantom Assassin, 
Nyx Assassin, Bane, Visage, 
Bounty Hunter.
Dark Seer
* Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.

Additional:
* Ion Shell is a very powerful weapon against Broodmother's Spiderlings and makes her laning much harder.
Visage
* 
Venomous Gale, 
Poison Sting and 
Poison Nova deal damage over time and will chip away at Gravekeeper's Cloak in addition to slowing an already sluggish hero.
* Venomancer's normal attacks deal Poison Sting and will chip away at Gravekeeper's Cloak.
Dark Seer
* Venomancer is a low health hero and low range hero who is easy to harass with Ion Shell on a creep in the early game.
* Venomancer depends entirely on all his slows to keep distance or chase, but since Surge ignores slows, it is nearly impossible for Venomancer to hunt or run away from Dark Seer or his surged teammates.
Visage
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.
Dark Seer
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer, Chaos Knight, Naga Siren, Terrorblade.
Visage
* Tiny can deal with Visage's Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's 
Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with 
Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Visage
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, Tiny and Undying have a very hard time killing Familiars.
Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's Kinetic Field or Slark's Pounce.
Dark Seer
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, Jakiro, 
Underlord, 
Leshrac, Dark Seer, 
Earthshaker, Timbersaw, Crystal Maiden.
