Sven
* 
Whirling Axes (Melee)'s blind makes Sven nearly useless in the early game and allows Troll Warlord to take him on comfortably.
* 
Battle Trance will mean Sven will never take Troll out in a 1vs1 with equal farm.
Additional:
* Berserker's Rage together with Troll Warlord's high attack speed gives Troll a high chance of rooting enemies, which allows Troll Warlord to man-fight Sven.
* Whirling Axes (Melee) provides a 60% miss chance, and the passive armor provided by Berserker's Rage makes Troll resilient to physical damage in early game. Sven's 
God's Strength is much less effective as a result.
* Beware that Sven can farm much faster than Troll Warlord by stacking ancients and clearing them with 
Great Cleave.
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.
Sven
* 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.
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.
Sven
* 
Cold Embrace saves any ally Sven initiates on and wastes the duration of God's Strength in team fights.
* 
Winter's Curse can be devastating to Sven's team, as his massive damage can take out a teammate before there is much time to react.
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.
Sven
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: 
Clockwerk, 
Beastmaster.
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.
Sven
* Multicast Fireblasts over the course of fights are a decent nuisance to stall Sven's massive damage output.
* Bloodlust and Ignite gives Ogre Magi's team the movement speed difference needed to chase and/or disengage against a Sven and his 
Warcry.
* Ignite provides strong damage over time to pressure Sven early on in the laning phase and keep his health low, delaying his transition into the jungle. Ignite is also an easy way to disrupt 
Blink Dagger, Sven's most popular way of initiation.
* Ogre Magi's presence in the laning phase both in terms of damage and durability keeps high pressure on Sven in lane.
* Purchasing an Aghanim's Shard allows Ogre Magi to greatly reduce the burst damage of Sven, who tends to build items focused on damage per hit instead of attack speed.
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.
Sven
* Heroes with naturally low mana can be easily shut down by E.M.P.: Sven, 
Tiny, 
Wraith King, 
Omniknight
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.
Sven
* Heroes who can fight back easily are not ideal matchups for Sven, such as 
Troll Warlord as mentioned above, 
Lone Druid and 
Templar Assassin.
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.
Sven
* Sven is very vulnerable to chain stun such as 
Lion, 
Shadow Shaman or 
Magnus.
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.
Sven
* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: Sven, 
Underlord, 
Bristleback.
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.
Sven
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, 
Slark, 
Phantom Lancer.
* Once you have an 
Aghanim's Scepter, Shadow Demon instantly reaches a new power spike and becomes a counter for a variety of heroes that have strong passives.
* Heroes that lose a great amount of their tankiness and become easier to finish off: Bristleback, 
Spectre, Phantom Assassin, Enchantress, 
Dragon Knight.
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
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.
Sven
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
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
* 
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.
Sven
* Heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him thanks to his 
Atrophy Aura, and will also be unable to ambush Underlord and his team if Underlord chooses to use 
Fiend's Gate to get to a designated point of the map: Phantom Assassin, 
Terrorblade, Troll Warlord, 
Drow Ranger, Phantom Lancer, 
Chaos Knight, Sven, Wraith King, 
Bounty Hunter, 
Alchemist, Templar Assassin, Nyx Assassin, 
Bane.
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.
Sven
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as 
Dark Seer. Underlord and 
Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
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.
Sven
* Undying can use Decay not only to reduce Sven's maximum health, but also to reduce the damage he can deal with his ultimate.
* Zombies spawned by Tombstone together with Flesh Golem slow Sven down significantly. Landing Sven's powerful but somewhat slow right-click on Tombstone would be a waste.
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.
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.
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.
Sven
* 
Cloak and Dagger makes Sven unable to detect where Riki is until he shows or his team provides detection.
* 
Smoke Screen will make Sven miss attacks before he has his Black King Bar.
Sven
* His Heartstopper Aura deals the same gradual damage over time no matter how high Sven builds his strength or health pool up, and should he fall down to a certain percentage, his high health will no longer matter if Necrophos manages to land his Reaper's Scythe, killing him instantly. But it is best if Necrophos can either catch him off guard before he can possibly use his Black King Bar (which is an item Sven players commonly purchase), or bait him out of it.
* Ghost Shroud prevents Sven from hitting Necrophos, and if he doesn't have his 
Storm Hammer available, it could make him completely immune to Sven and allow Necrophos to easily kite him around.
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.
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.
Sven
* Against her Untouchable, Sven is barely able to hit Enchantress even with his Black King Bar.
Sven
* Primal Roar takes Sven out of the fight completely, even with Black King Bar.
Sven
* Heroes that deal few, powerful instances of damage, like 
Oracle, Lion, or Sven, have a hard time breaking through Gravekeeper's Cloak.
Sven
* Heroes that can prevent Sven from farming are very strong against him. Such as 
Riki and Bounty Hunter with their respective invisibility.
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.
Sven
* Heroes who thrive on teamfights can be a problem, such as 
Venomancer, 
Necrophos, 
Centaur Warrunner...
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.
Sven
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, Alchemist, Troll Warlord, Wraith King, Tiny, Sven.
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.
Sven
* Heroes who can take advantage of God's Strength being on cooldown are also not great matchups, such as Templar Assassin, 
Morphling and 
Huskar.
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.
Sven
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, 
Lifestealer, 
Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Sven
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,
Bloodseeker, Lifestealer, Troll Warlord, Sven
Sven
* Heroes who thrive on teamfights can be a problem, such as Venomancer, Necrophos, Centaur Warrunner...
Sven
* Heroes who can take advantage of God's Strength being on cooldown are also not great matchups, such as Templar Assassin, Morphling and Huskar.
Sven
* Batrider often hides in the trees to initiate on a target. As such, he has a slight edge against heroes that have no scouting tools and cannot see him coming, such as Lion or Sven.
Sven
* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mana Shield negates much of Sven's burst damage.
Additional:
* 
Mana Shield makes it very hard for Sven to burst her within Storm Hammer's stun duration.
* 
Stone Gaze makes it very difficult for Sven to fight Medusa at any stage of the game.
* 
Mystic Snake can slow Sven down enough for allies to capitalize on his commitment in a fight.
Primal Beast
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as 
Medusa, Drow Ranger...
Sven
* 
Berserker's Call prevents Sven from bursting his targets before Axe can interfere. The worst kind of opponent for Sven is one who can stop him from attacking who he wants to, which is exactly what Axe does.
* 
Culling Blade may finish off Sven before he has the chance to lifesteal or run with Warcry.
* Axe is a very common 
Blade Mail carrier which will make very short work of a Sven with God's Strength activated.
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.
Sven
* Sven has no easy way to burn 
Refraction charges and needs help from teammates to kill TA successfully.
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...
Sven
* Great Cleave with God's Strength clears Terrorblade's illusions quickly.
* Storm Hammer's AoE stuns Terrorblade and his illusions.
* Warcry gives Sven and his allies armor to withstand Terrorblade's only-physical damage output.
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.
Sven
* Great Cleave cleans up Spiderlings quicker than most spells, as it ignores their magic resistance.
* Sven is a natural Black King Bar carrier, protecting him from Silken Bola, Spawn Spiderlings and 
Orchid Malevolence.
* Warcry and God's Strength allow Sven to easily out-damage Broodmother.
Additional:
* Great Cleave can clear Spiderlings very quickly, and give Sven lot of gold.
* Warcry shields Sven and his allies against Broodmother and her Spiderlings.
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.
Sven
* Late game heroes are Sven's favourite kind of opponent, such as 
Anti-Mage, Spectre and 
Shadow Fiend.
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.
Sven
* Storm Hammer's faster projectile speed and cast time allows Sven to stun Chaos Knight and his illusions before he can cast Chaos Bolt.
* Warcry's armor bonus counteracts Reality Rift's debuff and reduces Chaos Knight's damage output.
* Great Cleave and God's Strength devastates Phantasm illusions.
Additional:
* Great Cleave is very effective against Chaos Knight's illusions.
* Storm Hammer's radius can catch all of Chaos Knight's illusions at once, especially after 
Reality Rift.
* Warcry shields Sven and his teammates against Chaos Knight's physical damage output.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, 
Naga Siren, Terrorblade.
Sven
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
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.
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as 
Lina, Slark and 
Zeus.
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.
Sven
* Heroes with high armor and/or durability can handle Juggernaut's ultimate, such as Sven and Dragon Knight.
Additional:
* Warcry allows Sven to tank the damage from 
Omnislash due to its high armor gain.
* However 
Blade Fury provides spell immunity which blocks the stun from Storm Hammer.
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.
Sven
* Heroes who cannot prevent Sven from killing towers will often struggle from a small map very early, such as Phantom Assassin, 
Storm Spirit and Phantom Lancer.
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.
Sven
* Special mention to Sven as he may not be able to get close, but if he does, God's Strength will make very short work of Sniper.
Sven
* Past the early game, Sniper is an easy target for Sven to jump on with Aghanim's Scepter upgraded Storm Hammer, Blink Dagger, 
Silver Edge or 
Harpoon, common items on Sven.
* Sven's high armor and health pool makes it difficult for Sniper to focus, as his main source of damage is his right click, especially if Sven uses Warcry.
* Sniper is very squishy, and will not stand a chance against Sven head on.
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.
Sven
* Heroes whose attacks can affect multiple enemies at once will clear Naga Siren's illusions. Such heroes include Sven, Magnus, Dragon Knight, Luna, Medusa, Templar Assassin, 
Gyrocopter, 
Muerta.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Sven
* Fragile supports who die in a few hits against Sven's high physical damage: 
Crystal Maiden, 
Vengeful Spirit, Dark Willow.
Primal Beast
* Any hero with low mobility and max healthsuch as 
Silencer, Crystal Maiden etc.
Sven
* Great Cleave and God's Strength destroys illusions in just a few hits.
* Storm Hammer's AoE stun will hit Phantom Lancer when he's grouped up with illusions.
* Sven's low mana causes him to take less damage from 
Diffusal Blade. This is further reduced by the armor bonus from Warcry.
Additional:
* Great Cleave and God's Strength cuts through Phantom Lancer's illusions in no time.
* Storm Hammer's AoE stun will hit Phantom Lancer and his illusions.
Sven
* Storm Hammer locks down Chen and his converted creeps.
* Great Cleave and God's Strength can destroy Chen and his creeps quickly.
* Warcry minimizes damage taken from creeps's attacks.
Additional:
* Great Cleave can quickly destroy Chen's creeps in team fights, before they have a chance to do much.
Sven
* Storm Hammer stunned can stops Snapfire's 
Mortimer Kisses.
Sven
* 
Doom generally does not impede Sven in almost any way, provided he has activated God's Strength beforehand.
Sven
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
Sven
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, 
Enigma, Luna, Naga Siren, 
Mars, 
Jakiro, Venomancer, 
Elder Titan, 
Faceless Void, 
Rubick, Keeper of the Light, 
Pugna, 
Invoker, Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, 
Phoenix, 
Razor, Huskar, 
Batrider, Kunkka, 
Tidehunter, Wraith King, 
Sand King, Medusa, 
Dawnbreaker.
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.
Sven
* Sprout is good for trapping melee carries with no escape abilities: Sven, Alchemist, Lifestealer etc.
Sven
* Heroes with cleave damage: Sven, Magnus, Kunkka.
Primal Beast
* 
Sprout gets destroyed by Trample and Onslaught.
Sven
* 
Avalanche and 
Toss will never be enough damage to take out Sven in a clean way.
* Tiny is very slow with low armour growth and does not buy items to sustain Sven's damage output.
Sven
* Great Cleave will kill Lycan's summons very rapidly.
* Warcry will allow Sven and his allies to tank Lycan's damage, which is mainly physical.
* Storm Hammer will damage and stun Lycan's as well as his summons.
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.
Sven
* God's Strength allows Sven to take down Death Prophet quickly, reducing the damage dealt over time from 
Exorcism.
* Warcry's bonus armor and movement speed is very useful for Sven and his teammates against Exorcism, which deals physical damage.
Sven
* With God's Strength, Warlock's Golem from 
Chaotic Offering will go down in a matter of seconds. The two weaker golems granted by Aghanim's Scepter will fare worse due to Great Cleave hitting both.
* Aghanim's Scepter upgraded Storm Hammer Aghanim's Scepter can dispel 
Shadow Word.
Additional:
* God's Strength combined with Great Cleave destroys Chaotic Offering golems within seconds.
* Warcry gives Sven and his allies armor to help against Warlock's Golem's heavy physical damage and movement speed to help escape Upheaval.
* Storm Hammer disrupts Upheaval.
Sven
* Great Cleave and God's Strength can take down Meepo and his clones very quickly.
* The lack of spell immunity for Meepo's clones makes them vulnerable to Storm Hammer.
Additional:
* Great Cleave will devastate Meepo's clones. Against a closely packed group, Sven does not even need to target the clone with the lowest health.
Sven
* Sven has a high health pool and is a natural Black King Bar holder and is very hard to kill for Lina.
* Sven also has high physical damage, making it easy for him to burst her down.
Sven
* God's Strength makes Sven one of the worst heroes to Duel.
* Storm Hammer can be used to interrupt Duels.
* Warcry gives a big boost in passive defensive ability with the active component to nearby allies.
* With the Aghanim Shard Warcry also gives nearby allies passive increases.
Sven
* Warcry makes it difficult to burst Sven down with both the passive (with Aghanim's Shard) and active component.
* Sven under the effect of God's Strength and his massive physical damage make Sven very dangerous to engage in the mid game.
Sven
* Storm Hammer interrupts Echo Stomp.
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
Sven
* Sven's Great Cleave can clear Anti-Mage's illusions from Manta Style and his high health pool and low mana, making Mana Void very ineffective, although keep in mind that Storm Hammer is extremely easy to reflect with a well-timed Counterspell.
Additional:
* Anti-Mage is fairly fragile, and cannot stand against Sven in a prolonged fight.
* Sven's Black King Bar and low base mana can protect Sven from the effects of 
Mana Break and 
Mana Void.
* Great Cleave destroys the illusions from Anti-Mage's 
Manta Style.
* Although Sven should be careful as a well-timed 
Counterspell can block and reflect Storm Hammer back at Sven.
Sven
* Heroes who cannot prevent Sven from killing towers will often struggle from a small map very early, such as Phantom Assassin, Storm Spirit and Phantom Lancer.
Sven
* Late game heroes are Sven's favourite kind of opponent, such as Anti-Mage, Spectre and Shadow Fiend.
Sven
* Generally heroes who don't rely on magical damage, such as Sven, Phantom Assassin, and Outworld Destroyer, as they can practically ignore Flesh Heap's damage block.
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
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: 
Spirit Breaker, Gyrocopter, 
Leshrac
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...
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Sven
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Sven
* Heroes who struggle to fight back against Sven at any point in the game are at a severe disadvantage: Alchemist, Anti-Mage, Crystal Maiden.
Sven
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer. Underlord and Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
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.
Sven
* 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.
Sven
* 
Purification can heal allies while dealing pure damage to Sven.
* 
Heavenly Grace can remove Storm Hammer's debuff immediately or make it a very mediocre stun.
* 
Guardian Angel negates Sven's massive damage during God's Strength.
* It should also be noted Sven can remove Omniknight's active spells with Aghanim's Scepter.
Sven
* Although Sven relies often on physical damage, an Aghanim's Scepter upgraded Storm Hammer can dispel Guardian Angel with its wide radius.
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...
Sven
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: Terrorblade, Sven, 
Clinkz, 
Windranger, Alchemist, Dragon Knight, Legion Commander
Sven
* Warcry can protect Sven and his teammates from 
Swashbuckle.
* With Black King Bar, Sven will be able to protect himself from most of Pangolier's skills.
Sven
* Heroes that rely on right-clicks will find themselves unable to damage opponents seriously after being affected by Static Link, like Sven, Bloodseeker, and 
Juggernaut.
Additional:
* 
Static Link saps Sven's insane attack damage, and goes through Black King Bar.
Primal Beast
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
Sven
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, 
Sniper, 
Monkey King, Sven.
Sven
* Sven with Aghanim's Scepter-upgraded Storm Hammer can easily chase down Windranger and dispel her Windrun at the same time.
Sven
* Muerta's attacks during 
Pierce the Veil ignore Sven's Warcry.
* Sven using God's Strength can be completely ignored by using Pierce the Veil.
* Sven with Aghanim's Scepter will still not be able to dispel Muerta's Ethereal form during Pierce the Veil.
* However, Sven is a natural purchaser of Black King Bar that can protect him from Pierce the Veil and the rest of Muerta's kit.
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.
Sven
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe, Dragon Knight, Sven.
Primal Beast
* Heroes who rely on burst damage with magical damage will struggle to kill Primal Beast: Spirit Breaker, Gyrocopter, Leshrac
Sven
* Melee carries during the laning phase: Sven, Slark
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...
Sven
* Pugna can save allies with both healing or by making them ethereal but needs to be careful of Sven's Aghanim's Scepter purge.
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.
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.
Sven
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
Sven
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like Lifestealer or Juggernaut or heroes that tend to pick up Black King Bar, like Sven.
Sven
* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, Vengeful Spirit, Dark Willow.
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.
Sven
* Sven can be easily kited since Weaver is a natural
Linken's Sphere carrier and Sven relies on 
Storm Hammer to disable and kill a hero.
Primal Beast
*
Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
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.
* Trample disarms Primal Beast, so casting
*
