Earthshaker
* Her 
Psionic Traps will usually disable Earthshaker's 
Blink Dagger prior to a teamfight, preventing him from initiating.
* 
Refraction blocks all of Earthshaker's abilities.
Skywrath Mage
* Templar Assassin easily withstands all the damage from Skyrwrath Mage, thanks to its first ability Refraction. In addition, Templar Assassin can kill Skywrath Mage with a single hit from under the second ability 
Meld.
Additional:
* Templar Assassin easily withstands all the damage from Skyrwrath Mage, thanks to its first ability Refraction. In addition, Templar Assassin can kill Skywrath Mage with a single hit from under the second ability Meld.
Earthshaker
* Earthshaker must be careful not to use Blink Dagger or 
Aghanim's Scepter upgraded 
Enchant Totem to blink into 
Riki's 
Smoke Screen or 
Night Stalker's 
Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.
Skywrath Mage
* Due to his low health and armor, Riki can easily kill Skywrath Mage.
* Smoke Screen prevents Skywrath from using all of his abilities, as he does not tend to buy 
Black King Bar.
* However, Skywrath Mage can easily kill Riki if he manages to root Riki with Rod of Atos or Gleipnir, followed by Dust of Appearance, Ancient Seal and Mystic Flare.
Earthshaker
* Earthshaker's stuns will rarely save him once Huskar has initiated on him with Life Break.
* A full initiation combo will not kill Huskar, only lower his health and increase his attack speed.
Skywrath Mage
* Skywrath Mage's armor and agility gain is very low, so when Huskar's 
Burning Spears stack they can take him down very quickly at any point of the game.
* 
Berserker's Blood grants bonuses as Huskar uses Burning Spears to harass Skywrath Mage, granting him attack speed, magic resistance, and strength as health regen, making it possible that Huskar can harass Skywrath Mage out of lane and sustain through his magic burst through staying injured throughout lane, or even the game.
* 
Life Break allows Huskar to jump onto Skywrath Mage, closing the distance between them and busting him down so he cannot run. This can be combed with 
Inner Fire, adding a movement speed slow if Aghanim's Shard is applied so Skywrath Mage cannot escape.
Skywrath Mage
* Heroes with high magical burst can easily kill Huskar when he is at low health: 
Lion, 
Lina, 
Skywrath Mage
Earthshaker
* Earthshaker must be careful not to use Blink Dagger or Aghanim's Scepter upgraded Enchant Totem to blink into Riki's Smoke Screen or Night Stalker's Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.
Additional:
* 
Fissure has a short stun and creates an impassable ridge. However, Night Stalker can fly over it during Dark Ascension.
* Night Stalker can find Earthshaker, disable his Blink Dagger with Void, and then take him out with Crippling Fear.
* Earthshaker may fail his blink combo against Night Stalker's team if he is not careful, as he can blink into the silence.
Skywrath Mage
* Heroes with silence such as Riki, 
Silencer, or Night Stalker prevents Skywrath Mage from using his spells.
Earthshaker
* Silencer's 
Global Silence and 
Doom's 
Doom makes Earthshaker temporarily useless.
Skywrath Mage
* Heroes with silence such as Riki, Silencer, or Night Stalker prevents Skywrath Mage from using his spells.
Skywrath Mage
* In the early-mid game, Skywrath consistently needs to use his entire mana pool to kill a hero, but Wraith King's 
Reincarnation allows him to finish off Skywrath after the first death, as Skywrath Mage will have likely expended all his mana.
Skywrath Mage
* Fate Edict can completely negate Skywrath Mage's heavy magic damage.
* Fortune End dispels 
Ancient Seal.
Earthshaker
* 
Spectral Dagger can be used to traverse past Fissure.
* 
Haunt will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating.
* On the other hand, Haunt will amplify damage done from Echo Slam. Use this to your advantage.
Additional:
* Spectre can use Haunt to intercept and disrupt Earthshaker's initiation attempts.
* Spectral Dagger can be used to traverse past Fissure.
* Earthshaker often travels alone when he is trying to initiate, so 
Desolate can be very effective against him.
* Beware that the Haunt illusions amplify the damage done from 
Echo Slam, which can prove fatal for Spectre's own team.
Earthshaker
* Venomancer's slows and magical damage-over-time works well against Earthshaker's which completes lack of mobility.
* 
Plague Wards are useful for slowing and kitting down Earthshaker, revealing him from initiating and re-initiating and putting his Blink Dagger on cooldown if Venomancer has vision over Earthshaker.
Additional:
* Earthshaker can be kited by Venomancer's slows, which is lack of mobility.
* Plague Wards is very useful for slowing and kitting down Earthshaker, revealing him from initiating and re-initiating and putting his Blink Dagger on cooldown.
Earthshaker
* Luna's 
Lucent Beams and 
Eclipse will prevent Earthshaker from initiating or re-initiating.
* Aghanim's Scepter upgraded Eclipse can be used to counter-initiate against Earthshaker after he uses Aghanim's Scepter upgraded Enchant Totem.
* Skilled Luna can buy either {I|Gleipnir
Additional:
* Luna's Lucent Beams and Eclipse will prevent Earthshaker from initiating or re-initiating.
* Aghanim's Scepter upgraded Eclipse can be used to counter-initiate against Earthshaker after he uses Aghanim's Scepter upgraded Enchant Totem.
* Skilled Luna can buy either {I|Gleipnir
Earthshaker
* Frequent healing from 
Death Pulse and 
Mekansm/
Guardian Greaves or 
Pipe of Insight makes it difficult for Earthshaker to execute his combo with Echo Slam.
* Necrophos usually buys 
Radiance to improve their burning aura damage from 
Heartstopper Aura will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating or re-initiating.
* 
Reaper's Scythe allows to kill Earthshaker while he blinks in, preventing him from executing his combo (although Earthshaker is rarely a primary target).
Earthshaker
* 
Rage prevents Earthshaker from damaging and stunning Lifestealer.
* 
Feast is very effective against Earthshaker, because of him being a strength hero, allowing Lifestealer to heavily harass and kill him.
* 
Open Wounds prevents Earthshaker from escaping after he initiated.
* 
Infest gives Lifestealer an easy way to escape should he get caught out by Earthshaker. And against carry Earthshaker, Aghanim's Scepter upgraded Infest can be used to disarm Earthshaker and attack him from within, rendering him unable to attack with Enchant Totem.
Earthshaker
* Ignite can prevent Earthshaker from escaping and/or initiating with Blink Dagger.
* Fireblast and Unrefined Fireblast may help prevent Earthshaker follow through with his combo after landing an Echo Slam.
Earthshaker
* 
Poison Attack and 
Viper Strike allowing to kite and slow Earthshaker significally, putting Blink Dagger on cooldown and preventing him from initiating or re-initiating.
* 
Nethertoxin breaks Aftershock. The silence from Level 25 talent also prevents Earthshaker from initiating or re-initiating.
Additional:
* Being a melee hero, Earthshaker's movement is liable to suppression by Poison Attack and Viper Strike.
* Earthshaker's kit, with the exception of Enchant Totem, deals magic damage. 
Corrosive Skin effectively blunts his killing potential with a standard Blink combo among other things.
* Nethertoxin disables 
Aftershock, which removes the stun and bonus damage from Enchant Totem and Echo Slam.
Earthshaker
* 
Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* 
Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.
Additional:
* Sniper is able to kite Earthshaker with his very long range.
* Sniper can dodge Earthshaker's stuns like Fissure and Enchant Totem with mobility items such as Blink Dagger, 
Force Staff/
Hurricane Pike and 
Shadow Blade/
Silver Edge.
* Sharpnel can be used to cancel Earthshaker's Blink Dagger and preventing effective use of his Echo Slam in a majority of situations.
Earthshaker
* 
Thunder Strike can be used to cancel Earthshaker's Blink Dagger.
* 
Glimpse brings Earthshaker back after he jumps on Aghanim's Scepter upgraded Enchant Totem.
* 
Static Storm if used on a fight can prevent Earthshaker from executing his combo after blinking in with Blink Dagger.
Earthshaker
* 
Geomagnetic Grip can be used to silence Earthshaker after he blinks in, preventing him from executing his combo.
* 
Magnetize does damage over time and thus disables Earthshaker's Blink Dagger for a long time.
Earthshaker
* Death Prophet's 
Crypt Swarm and 
Spirit Siphon can repetively damage Earthshaker, preventing him from using Blink Dagger.
* 
Silence can be used to silence Earthshaker after he blinks in with Blink Dagger, preventing him from executing his combo.
* Spirits from 
Exorcism are completely invulnerable and cannot interact with anything at all, which will greatly weaken damage from Echo Slam. This can put Earthshaker in a serious disadvantage against Death Prophet.
Earthshaker
* 
Phase Shift allows Puck to dodge all of Earthshaker's abilites.
* 
Waning Rift disables Earthshaker's stuns, leaving him and his team vulnerable.
* 
Dream Coil takes a stun from Earthshaker if he tries to escape from Blink Dagger or Enchant Totem upgraded from Aghanim's Scepter.
Earthshaker
* 
Static Link drains the damage bonus from Enchant Totem, until he purchase Aghanim's Scepter or Force Staff to break it.
* 
Storm Surge with Razor's high mobility items can easily avoid all of Earthshaker abilities.
* 
Plasma Field & 
Eye of the Storm prevents Earthshaker escaping from Blink Dagger.
Additional:
* Static Link drains Earthshaker's bonus damage from Enchant Totem until he purchases an Aghanim's Scepter or Force Staff to break it.
* Eye of the Storm and Plasma Field can disable Earthshaker's Blink Dagger, preventing him from initiating or re-initiating.
Skywrath Mage
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as Skywrath Mage, 
Techies, 
Juggernaut, 
Shadow Shaman, or 
Ogre Magi.
Additional:
* 
Aphotic Shield removes silences, slows and stuns, possibly foiling a full-duration Mystic Flare.
* 
Borrowed Time makes it impossible to burst 
Abaddon down, even healing him up due to Mystic Flare's damage.
Earthshaker
* Heroes with no mobility will take some good damage from Sand King's spells: 
Dragon Knight, 
Jakiro, 
Pugna, 
Earthshaker.
Skywrath Mage
* Slow-moving projectiles: Skywrath Mage, 
Tinker, 
Necrophos
Additional:
* Skywrath Mage's low health makes him rather easy prey for Nyx Assassin and his lack of armor generally means he'll take the full brunt of a 
Vendetta strike.
* 
Mind Flare turns Skywrath Mage's high intelligence growth against him and deals heavy damage.
* 
Spiked Carapace gives Nyx some degree of protection against Skywrath's spells.
Earthshaker
* 
Warlock often stays back and counter-initiates by dropping his 
Chaotic Offering on Earthshaker and his allies.
Skywrath Mage
* Fragile heroes: Bounty Hunter has decent nuking capabilities with Shiruken Toss and Jinada thus making fragile heroes easy picks for ganking. Few examples of such heroes are:
Crystal Maiden, Pugna, Skywrath Mage, 
Io, 
Witch Doctor, etc.
Earthshaker
* 
Invoker's 
E.M.P. is extremely effective against Earthshaker due to his low natural mana.
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or 
Phantom Assassin, the latter occasionally downing a support Skywrath in a single 
Stifling Dagger.
Skywrath Mage
* Heroes with a low health pool (Crystal Maiden, Skywrath Mage etc)
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Earthshaker
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, Riki, 
Weaver, Earthshaker, 
Nyx Assassin, etc. that are constantly moving around the map.
Earthshaker
* Silencer's Global Silence and Doom's Doom makes Earthshaker temporarily useless.
Earthshaker
* 
Thundergod's Wrath will often disable Earthshaker's Blink Dagger before a fight starts.
Skywrath Mage
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, 
Kunkka, 
Puck, Skywrath Mage, 
Spirit Breaker, 
Tusk and others.
Skywrath Mage
* 
Mana Break drains Skywrath Mage of his mana, slowing him and dealing bonus damage while rendering him unable to cast his spells.
* 
Blink makes it incredibly easy for Anti-Mage to close the gap between himself Skywrath Mage to right-click him down. He can also use Blink to get away and escape into fog of war.
* Anti-Mage passively reduces enemy spell damage with 
Counterspell, and can activate the ability to block and send back Skywrath's Ancient Seal or Arcane Bolt, causing him to silence himself or deal massive damage to himself.
* Skywrath Mage's large mana-costs makes him an easy target for 
Mana Void.
* Anti-Mage often builds Black King Bar and 
Manta Style which can dispel Ancient Seal and Concussive Shot.
Skywrath Mage
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, 
Grimstroke, Witch Doctor, Riki, 
Faceless Void, Skywrath Mage, Puck.
Skywrath Mage
* Due to the high mana cost of his spells and the low cool down of them, Nether Ward can seriously damage Skywrath Mage if he isn't careful.
* Skywrath Mage's fragility makes him very susceptible to Pugna's high burst damage.
Additional:
* 
Nether Ward will make Skywrath Mage next to useless in fights, as his low hp pool will not allow him to sustain through the damage of the ward should he choose to cast spells. Be wary though that Skywrath's huge burst will make very quick work of Pugna's low hp should the ward be destroyed, and 
Decrepify won't help Pugna at all.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, 
Bane, Pugna, 
Pudge.
Earthshaker
* Supernova allows Phoenix to save himself (or an ally, with Aghanim's Scepter) through Echo Slam. Earthshaker will also have a difficult time destroying the supernova, due to his low base attack time and poor agility.
* Icarus Dive can pass through Earthshaker's Fissure.
* Most of Phoenix's abilities disable Earthshaker's Blink Dagger for a good period of time due to the damage-over-time nature of its spells.
Skywrath Mage
* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like 
Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.
Earthshaker
* Windrun can be used to dodge Earthshaker's abilities if Windranger has a quick reaction time.
* Focus Fire and Windrun allows Windranger to kite Earthshaker.
* A Windranger with fast fingers can prevent Earthshaker from using Fissure with Shackleshot.
Skywrath Mage
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: 
Zeus, Tinker, 
Leshrac, 
Viper, Skywrath Mage, Lion, Lina, 
Venomancer.
Earthshaker
* Battery Assault will continuously interrupt Earthshaker's long cast animations.
* Power Cogs can also trap Earthshaker after he initiates.
Additional:
* 
Battery Assault interrupts Earthshaker's long cast animations, preventing him from using any abilities apart from Echo Slam.
* 
Power Cogs often separate the battlefield so that both enemies and allies are unlikely to cluster.
* 
Rocket Flare allows Clockwerk to scout Earthshaker before a fight starts and potentially cancel his Blink Dagger.
* 
Hookshot enables Clockwerk to catch Earthshaker before he gets a chance to initiate a fight.
Skywrath Mage
* Skywrath Mage's 
Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.
Skywrath Mage
* Skywrath Mage's very low health allows Monkey King to ambush and finish him off quickly.
Earthshaker
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, 
Alchemist, Earthshaker, 
Razor, Tinker, Leshrac, 
Queen of Pain
Earthshaker
* Earthshaker's AoE stuns can save ally against 
Duel, forcing Legion Commander to spend Aghanim's Scepter or Black King Bar.
Skywrath Mage
* Mystic Flare can easily burst down Legion Commander while she is Dueling.
Earthshaker
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, Earthshaker, 
Elder Titan, Faceless Void, Invoker, 
Legion Commander, 
Mars, 
Primal Beast, Riki, Shadow Shaman, Silencer, 
Vengeful Spirit, 
Void Spirit.
Skywrath Mage
* 
Arcane Bolt can target Terrorblade's low health pool in the laning phase.
* Ancient Seal can prevent Terrorblade from casting Sunder.
* Mystic Flare can be used to great effect to burst Terrorblade down before he gets a Manta Style or a Black King Bar.
Earthshaker
* Echo Slam will deal immense damage due to the amount of creeps Chen will have.
* Fissure and Enchant Totem deal large amounts of AOE damage, wearing down non-ancient creeps that Chen converts.
Skywrath Mage
* Heroes with either magical, physical or pure damage burst: Bane, 
Ember Spirit, Leshrac, Lina, 
Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, 
Ursa, Void Spirit.
Earthshaker
* Earthshaker's many stuns can lock down slippery heroes like 
Slark in his 
Shadow Dance and Weaver in his 
Shukuchi.
Skywrath Mage
* Even though 
Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, 
Morphling, 
Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Additional:
* Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Skywrath Mage
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using 
Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* 
Reactive Armor does not trigger on magic damage or spells, meaning that even a Pipe of Insight won't give him the massive sustain he normally gets from attacks.
Additional:
* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Skywrath Mage
* Arcane Bolt's low cooldown allows him to deal consistent damage to Morphling, and is a viable way to disable Linken's Sphere.
* Ancient Seal prevents Morphling from using any of his skills, giving Skywrath Mage and his team ample time to burst Morphling down.
* Mystic Flare coupled with a stun/root can easily burst Morphling down, especially if he has more stats shifted to Agility.
* Alternatively, Morphling can use Morph to use Skywrath Mage's own silence and nukes against him.
Earthshaker
* Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for Blink Echo Slams.
Skywrath Mage
* Ancient Seal instantly shuts down Dark Willow's abilities, rendering her defenseless against his high burst damage spells, while she cannot cast spells of her own.
* Mystic Flare deals immense burst damage in an area, damaging Dark Willow through Shadow Realm.
Earthshaker
* Fissure does a great job at interrupting 
Black Hole immediately, especially with Blink Dagger and 
Aether Lens.
* Echo Slam's damage potential increases due to the eidolons created by 
Demonic Conversion.
Skywrath Mage
* Skywrath Mage can easily harass Alchemist in the laning phase with multiple Arcane Bolts. Additionally, if Alchemist is in the process of throwing an 
Unstable Concoction, and has no way to dispel Ancient Seal, the self stun becomes an easy set up for Mystic Flare.
* Caution, however, as a decently farmed Alchemist with {Item ID:Radiance} and {Item ID:Manta Style} can easily send illusions to harass and force Skywrath Mage out.
Skywrath Mage
* A good Skywrath Mage with quick fingers will punish Queen of Pain for blinking aggressively. Ancient Seal is a six second silence with no cast time, so he can interrupt either her Shadow Strike or Sonic Wave, and a good Mystic Flare on top of that will seal the deal for her.
* Ancient Seal also has pretty good range so he could get it off before she blinks away.
Earthshaker
* Earthshaker's Aftershock combos and Fissure can stun Muerta consecutively and minimize Pierce the Veil's effective duration.
Skywrath Mage
* Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.
Earthshaker
* Fissure interrupts Spirit Breaker during 
Charge of Darkness.
Skywrath Mage
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.
Earthshaker
* Zombies summoned from Tombstone will amplify the damage of Echo Slam due to them increasing the echo damage.
Earthshaker
* Treants increase Echo Slam's damage.
* Earthshaker's AoE stuns can hit Nature's Prophet through 
Sprout, without having direct line of sight, in order to interrupt 
Teleportation.
Additional:
* Echo Slam can do a lot of damage to Nature's Prophet and his teammates if they stand close to his Treants.
Skywrath Mage
* 
Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast 
Winter's Curse on him. And if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
* However, bear in mind that Skywrath Mage has seriously awful armor, and that can make him an adequate target to being turned against his own team with Winter's Curse, which can result in his death quickly.
Additional:
* Cold Embrace is the perfect setup for Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.
Skywrath Mage
* Skywrath Mage stands perfectly on the center line against Tinker, thanks to his nuke and silence. Also, thanks to his abilities, he can quickly kill a victim, and Tinker is one of the most subtle heroes in the game
Additional:
* Skywrath Mage stands perfectly on the center line against Tinker, thanks to his nuke and silence. Also, thanks to his abilities, he can quickly kill a victim, and Tinker is one of the most subtle heroes in the game
Earthshaker
* 
Mirror Image's illusions increase Echo Slam's damage.
Additional:
* Earthshaker's strong AoE abilities can clear Naga Siren's illusions, or at least make it easier to distinguish the real one by the damage they take.
* Echo Slam deals more damage against more enemies, which can be devestating against Naga Siren and her illusions.
Earthshaker
* All of his spells can stun Elder Titan and interrupt Echo Stomp's channeling thanks to Aftershock.
* Fissure is particularly good for that purpose thanks to its long range.
* Elder Titan relies heavily on his spells and a chain-stun combo will usually be followed by certain death.
Earthshaker
* Aftershock in combination with Enchant Totem prevents Broodmother from continuing to attack Earthshaker without being repeatedly stunned.
* Echo Slam is greatly amplified by Spiderlings, often instantly killing Broodmother, her swarm, and anyone else unfortunate enough to be nearby.
* Earthshaker's vast amount of stuns makes it difficult for Broodmother to continue attacking enemies (to continue lifestealing with Insatiable Hunger) without Black King Bar.
Additional:
* Echo Slam's damage potential increases phenomenally due to Broodmother's hordes of spiderlings and spiderites.
* Long ranged Fissures can hit Broodmother if she runs into the treeline at the edges of the map.
Skywrath Mage
* Heroes with nukes: Bane, 
Lich, Lion, Skywrath Mage
Additional:
* 
Untouchable is useless versus constant Arcane Bolts, and it doesn't help that her strength gain is the lowest in the game.
* A jungle Enchantress can weaken lanes and make Skywrath Mage's job easier.
* The magic amplification from Ancient Seal makes her even squishier to Skywrath and his allies' magic nukes.
Skywrath Mage
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, 
Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, 
Oracle.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Skywrath Mage
* Heroes that can easily kill Faceless Void from outside his Cronosphere; 
Sniper, Skywrath Mage, etc.
Skywrath Mage
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Skywrath Mage
* 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.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Skywrath Mage
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, Leshrac, Lina, Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, Tinker, Ursa, Void Spirit.
Earthshaker
* Melee carries who usually buy an early Black King Bar, and have gap closing abilities can be good against the Arc Warden, such as Slark, Riki, Earthshaker with Aghanim's Scepter, 
Sven with Aghanim's Scepter etc.
Skywrath Mage
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single Stifling Dagger.
Skywrath Mage
* While Phantom Assassin can kill Skywrath Mage in a few strikes, Skywrath Mage can also do the same to her if she is not careful.
* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with 
Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Additional:

* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.
Earthshaker
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, 
Storm Spirit
Skywrath Mage
* Similar to Timbersaw, Storm Spirit builds items that don't help against silences.
* An 
Orchid Malevolence will most likely silence you first. However, if you grab a 
Eul's Scepter of Divinity, you might dispel his silence and turn the tides to your favor.
* Root and silence are Storm Spirit's ultimate counters. Skywrath Mage has a silence in his kit, and has 
Rod of Atos as his core item. If he dispels one, you cast the other, both leaving him vulnerable.
* If he builds Black King Bar, he spends 4050 gold that doesn't help him snowball effectively.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like 
Chaos Knight and 
Phantom Lancer, or by Heroes that summon other units like 
Lone Druid, 
Lycan and 
Beastmaster.
Earthshaker
* Having many summons out will cause Echo Slam to deal extra damage.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Earthshaker
* Phantom Lancer's many illusions increase Echo Slam's damage.
Additional:
* Echo Slam deals tremendous damage when multiplied by Phantom Lancer's illusions.
* Earthshaker's AoE abilities can quickly kill Phantom Lancer's illusions.
* Enchant Totem with Aghanim's Scepter gives Cleave to help destroy illusions.
Skywrath Mage
* Once you get a Black King Bar, squishy spellcasters like Zeus, Skywrath Mage and others will be probably easy to deal with.
Earthshaker
* A well landed Fissure can potentially take Lycan out of the fight for several seconds, who heavily relies on precious seconds from Black king bar and Shapeshift to fight.
* Aftershock reduces the effectiveness of his summons and can prove quite irritating for Lycan.
* Echo Slam is very powerful with the sheer amount of Lycan's units and will cause him to think twice when pushing towers.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Earthshaker
* Echo Slam will deal a colossal amount of damage to your Phantasms, as will Fissure at lower levels.
* The area stuns from Aftershock will always stun Chaos Knight's illusions, since they can't use Black King Bar.
* However, Earthshaker should not attempt to fight a farmed Chaos Knight, since he will be completely obliterated by Chaos Knight's colossal damage output, even if he managed to land an Echo Slam
Additional:
* Echo Slam's damage potential increases due to Chaos Knight's 
Phantasm illusions.
Skywrath Mage
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and Phantom Lancer, or by Heroes that summon other units like Lone Druid, Lycan and Beastmaster.
Skywrath Mage
* Mystic Flare can be used to effectively ignore the Spirit Bear entirely and burst Lone Druid during the early mid game.
* 
Concussive Shot and Arcane Bolt will provide vision of Lone Druid allowing for better chase in teamfights before the Spirit Bear can do too much damage.
* Ancient Seal denies the ability to transform into 
True Form and receive bonus HP from the skill.
Skywrath Mage
* Skywrath Mage's abilities are single targeted and he can't use Mystic Flare to its fullest potential, since all Meepos spread the damage between them. He also has no disables to prevent Meepo from Poofing to another one (unless he can get Ancient Seal off first).
Earthshaker
* Each of Meepo's clones count as real heroes, meaning that an Echo Slam hitting them will deal catastrophic damage to Meepo and his team.
* Eathshaker's AoE stuns can interrupt Meepo's 
Poof cast animation.
Additional:
* Echo Slam deals catastrophic damage against a cluster of Meepos and anyone nearby.
* He can potentially stunlock any number of Meepos for a fairly long duration, often enough to finish one off.
Earthshaker
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit
Earthshaker
* Earthshaker's many stuns can lock down slippery heroes like Slark in his Shadow Dance and Weaver in his Shukuchi.
Additional:
* Earthshaker's many AoE stuns help lock down Slark and will often waste the duration of Shadow Dance.
* As a frequent Force Staff buyer, he can later on escape or save teammates from Pounce.
Earthshaker
* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit
Skywrath Mage
* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Earthshaker
* Both 
Ice Path and 
Macropyre are the good setup against Earthshaker after he jumps in with Blink Dagger, and stay out of Echo Slam initiation radius.
* Jakiro's damage over time abilities can potentially disable Earthshaker's Blink Dagger.
Skywrath Mage
* Ancient Seal can silence Jakiro and make him vulnerable to magical spells up to 6 seconds.
* Skywrath Mage can usually burst down Jakiro with his high damage magical spells.
Earthshaker
* Outworld Destroyer's pure and magical damage is particularly effective against Earthshaker.
Astral Imprisonment catches Earthshaker while he blinks in, preventing him from executing his combo.
Arcane Orb, therefore depleting his mana pool and mana regeneration.
Sanity's Eclipse deals high damage to Earthshaker, due to his low intelligence and mana pool.
*
* Earthshaker has mana troubles, and Outworld Destroyer's abilities can press this by stealing intelligence comes from
*
Skywrath Mage
* Outworld Destroyer can steal more mana with
Astral Imprisonment from 
Skywrath Mage with 
Shield of the Scion (granted by 
Aghanim's Shard). Shield of the Scion grants Skywrath Mage bonus intelligence every time he deals magic damage to an enemy hero with his abilities. The higher his intelligence, the larger his mana pool. Since Astral Imprisonment steals based on the target's max mana, Outworld Destroyer can steal much more mana from Skywrath Mage.
