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.
Primal Beast
* Glimpse can prevent Primal Beast from initiating for most of the game with Onslaught.
* While Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in 
Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a 
Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.
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.
Primal Beast
* Primal Beast is disarmed during Trample so will be unable to destroy a 
Supernova no matter how close it is to him.
* The same ability can also be used to save allies with the help of an Aghanim's Scepter.
* 
Sun Ray will do thousands of damage to Primal Beast if surviving a full channel time due to his high health scaling for the ability.
* 
Icarus Dive is a fantastic way to escape Primal Beast after he has used Onslaught.
* Phoenix has a naturally very high health pool making it hard for Primal Beast to deal with him with his magical damage.
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.
* Earthshaker has mana troubles, and Outworld Destroyer's abilities can press this by stealing intelligence comes from 
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.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as 
Troll Warlord, 
Lone Druid and 
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
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.
Primal Beast
* Any ganking heavy support can be a big problem for Primal Beast, such as: 
Earth Spirit, 
Grimstroke before he has a Black King Bar.
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.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: 
Lich, 
Ogre Magi, 
Winter Wyvern.
Earthshaker
* 
Invoker's 
E.M.P. is extremely effective against Earthshaker due to his low natural mana.
Primal Beast
* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (
Tornado, 
Cold Snap, and 
Ice Wall all help to disable Primal Beast and control him from a distance.
* E.M.P. disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow-paced hero and not particularly known for being survivable against a rampaging Primal Beast with Black King Bar.
Primal Beast
* 
Borrowed Time allows him to both exit his stuns prematurely and turn Trample into healing for himself. His Aghanim Scepter only prevents the automation of the spell, Abaddon himself can still manually activate it.
* 
Aphotic Shield will immediately debuff any stuns Primal Beast has put on allies but won't stop him from being stunned if casted on Abaddon.
Primal Beast
* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
* Oracle can interrupt Primal Beast's 
Onslaught charge with a well-timed Fortune's End.
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
Additional:
* 
Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself.
* 
Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
* 
False Promise can interrupt Primal Beast's abilities, as well as further delay Primal Beast from dealing lethal burst damage. In combination with Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.
Primal Beast
* Primal Beast's abilities require movement to deal damage, making 
Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to 
Blood Rite's powerful silence without items to counter it.
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.
* Viper Strike can disable 
Aftershock, which removes the stun and bonus damage from Enchant Totem and Echo Slam.
Earthshaker
* 
Arcane Bolt allows Skywrath Mage to harass Earthshaker out of lane.
* 
Ancient Seal is an instant silence that can be pre-cast onto Earthshaker to disrupt his combo, before he uses Blink Dagger to initiate.
* 
Mystic Flare will nuke Earthshaker down while he stands in place during his long cast animations.
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.
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.
Primal Beast
* The ensnare from melee 
Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build 
Fervor on him.
* 
Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* 
Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* 
Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death.
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.
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).
Primal Beast
* 
Time Walk makes it impossible for Primal Beast to stay on top of Faceless Void with his abilities and allows him to heal burst damage dealt to him.
* Once Faceless Void has an 
Aghanim's Shard, Onslaught can be easily escaped. He could also choose to get a lower cooldown on Time Walk, making it even harder for Primal Beast to catch him in fights or stop his initiations.
* 
Time Dilation will make Primal Beast useless for an extended time after casting his abilities if he does not have a dispel.
* 
Chronosphere has many uses such as stopping Primal Beast from casting abilities on him or allies or even on a teammate, since Primal Beast has no way to assist allies trapped within the sphere.
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.
Earthshaker
* 
Thundergod's Wrath will often disable Earthshaker's Blink Dagger before a fight starts.
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.
Primal Beast
* 
Soulbind prevents Primal Beast from being able to use Onslaught or his abilities to great effect for a lengthy amount of time.
* 
Phantom's Embrace is very difficult for Primal Beast to remove due to his slow attack speed and Trample preventing him from attacking.
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
* 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.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as 
Shadow Shaman, 
Lion, 
Nyx Assassin.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Earthshaker
* Heroes with no mobility will take some good damage from Sand King's spells: 
Dragon Knight, 
Jakiro, 
Pugna, 
Earthshaker.
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
* 
Warlock often stays back and counter-initiates by dropping his 
Chaotic Offering on Earthshaker and his allies.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes 
Dazzle, 
Shadow Demon and 
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Primal Beast

Earthshaker
* 
Silencer's 
Global Silence and 
Doom's 
Doom makes Earthshaker temporarily useless.
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.
Primal Beast
* 
Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
Earthshaker
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: 
Luna's Aghanim's Scepter upgraded 
Eclipse, 
Dawnbreaker's 
Solar Guardian, 
Axe's 
Berserker's Call,

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.
Primal Beast
* Special mention to 
Lifestealer who can use Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.
Primal Beast
* 
Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
* Trample disarms Primal Beast, so casting 
The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
* 
Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
Earthshaker
* Earthshaker's many stuns can lock down slippery heroes like Slark in his 
Shadow Dance and Weaver in his Shukuchi.
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.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like 
Keeper of the Light, Luna, 
Templar Assassin...
Earthshaker
* Earthshaker's Aftershock combos and Fissure can stun Muerta consecutively and minimize 
Pierce the Veil's effective duration.
Primal Beast
* Pierce the Veil does not prevent Primal Beast from using any of his spells to their fullest and is one of the few heroes that can disable her during her ultimate and a common Black King Bar purchase. She will also likely be fatal to herself if Primal Beast has a 
Blade Mail active.
* 
Gunslinger will be disabled if Primal Beast buys an Aghanim's Scepter.
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.
Primal Beast
* Sprout gets destroyed by Trample and Onslaught.
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.
Primal Beast
* While Broodmother can hide in the trees with 
Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* 
Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While 
Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* 
Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.
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.
Primal Beast
* Terrorblade has no stun and is vulnerable to Primal Beast's spell comboes due to his low health points in the laning stage and mid game.
* 
Reflection can be dispelled using Primal Beast's level 15 left talent.
* 
Sunder is the only real threat Terrorblade has against Primal Beast but he may die before he can even use it.
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.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as 
Chaos Knight, Naga Siren, 
Terrorblade.
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.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, 
Witch Doctor, Bane, Pugna, 
Pudge.
Primal Beast
* Primal Beast has multiple ways to cancel 
Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, 
Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.
Earthshaker
* Fissure interrupts Spirit Breaker during 
Charge of Darkness.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: 
Spirit Breaker, Gyrocopter, 
Leshrac
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Primal Beast
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and 
Omniknight should play very cautiously alone...
Earthshaker
* Having many summons out will cause Echo Slam to deal extra damage.
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.
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.
Earthshaker
* Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for Blink Echo Slams.
Primal Beast
* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's 
Empower and can even contribute to his Uproar stacks.
* Using 
Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.
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.
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.
Primal Beast
* 
Dark Pact, Shadow Dance and 
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with 
Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with 
Essence Shift and may allow Primal Beast to build Uproar stacks against him very rapidly.
* If Primal Beast buys an Aghanim's Scepter he can also break Essence Shift from working on attacks which is a big part of Slark's damage output.
Primal Beast
* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both 
Cold Feet and Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While 
Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.
Primal Beast
* Primal Beast can use Uproar to tank a portion of 
Omnislash, making him much more likely to survive it. Primal Beast can also charge away from Omnislash using Onslaught as the spell ends.
* 
Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as 
Ethereal Blade and 
Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.
Primal Beast
* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of Ethereal Blade, 
Vanguard and 
Shiva's Guard all of which are very good against 
Coup de Grace and 
Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once 
Blur becomes more potent, she may find herself being overwhelmed by Trample and Onslaught instead.
* Primal Beast's ultimate goes through spell immunity and his level 25 talent makes it even more devistating against Phantom Assassin.
* Primal Beast can dispel 
Stifling Dagger and any attack modifers it applies with his left level 15 talent.
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 will deal catastrophic damage against a cluster of Meepos and anyone nearby.
* Aftershock allows Earthshaker's abilities to potentially stun any number of Meepos for a fairly long duration, often enough to finish one off.
Earthshaker
* Zombies summoned from Tombstone will amplify the damage of Echo Slam due to them increasing the echo damage.
Earthshaker
* Earthshaker's AoE stuns can save ally against 
Duel, forcing Legion Commander to spend Aghanim's Scepter or Black King Bar.
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
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: 
Necrophos, 
Phoenix, Alchemist, Earthshaker, Razor, 
Tinker, Leshrac, Queen of Pain
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Primal Beast
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, 
Centaur Warrunner.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Earthshaker
* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.
Primal Beast
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, 
Beastmaster and Primal Beast are good examples of this.
Additional:
* Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* 
Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including 
Counter Helix or even a Blade Mail.
* Getting Primal Beast low enough to use a successful 
Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a Vanguard.
Primal Beast
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as Medusa, 
Drow Ranger...
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.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...
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.
Primal Beast
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.
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.
Primal Beast
* 
Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can also dispel Spectral Dagger's slow with his left level 15 talent, making it completely useless against him.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant matchup for Spectre.
* Should Primal Beast buy an Aghanim's Scepter he can also break both passive abilities.
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
Primal Beast
* Primal Beast has a massive healthpool making it very difficult to get through it with a nuke such as Eclipse or Lucent Beam.
* Primal Beast is faster than Luna, as one of her main ways to escape danger, is very problematic for her in the laning stage especially.
* His ultimate goes through debuff immunity, making Luna's Black King Bar less effective.
* Primal Beast commonly buys Blade Mail which is a big problem for a single target bursting hero like Luna.
Earthshaker
* Silencer's Global Silence and Doom's Doom makes Earthshaker temporarily useless.
Primal Beast
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
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.
Primal Beast
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
Primal Beast
* 
Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.
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.
Primal Beast
* Heroes who can do scaling health damage to Primal Beast are very threatening for the hero. Such as: Phoenix, Tinker etc.
Primal Beast
* Heroes with unorthodox escapes will struggle against Primal Beast, such as 
Nature's Prophet, Tinker, and Templar Assassin.
Earthshaker
* Battery Assault will continuously interrupt Earthshaker's long cast animations.
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.
* Power Cogs can also trap Earthshaker after he initiates.
Additional:

Primal Beast
*
Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well. 
Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking. 
Rocket Flare and 
Jetpack (from purchasing 
Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
