Sven
* Sven is very vulnerable to chain stun such as 
Lion, 
Shadow Shaman or 
Magnus.
Gyrocopter
* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: 
Lina, Lion, 
Zeus
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.
Gyrocopter
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: 
Storm Spirit, Morphling, 
Ember Spirit
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.
Gyrocopter
* Guardian Angel negates most of Gyrocopter's physical АоЕ damage.
* Heavenly Grace dispels Homing Missile stun.
Sven
* Although Sven relies often on physical damage, an Aghanim's Scepter upgraded 
Storm Hammer can dispel Guardian Angel with its wide radius.
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.
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.
Gyrocopter
* 
Rage ignores all of Gyrocopter's magical attacks.
* 
Feast helps Lifestealer out-damage Gyrocopter at close range.
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.
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.
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.
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.
Gyrocopter
* 
Blink makes it hard for Gyrocopter to pin down Queen of Pain.
* 
Sonic Wave is very effective at ganking Gyrocopter in the early game.
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.
Gyrocopter
* Timbersaw is often too mobile and durable for Gyrocopter to bring down with his area attacks.
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.
Gyrocopter
* 
Time Walk makes it hard for Gyrocopter to pin down Faceless Void. With 
Backtrack it also negates most of his attacks.
* 
Time Dilation will prevent Gyrocopter from using his cooldown spells.
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.
Gyrocopter
* Any hero with a low HP pool is easy for Tinker to nuke down: 
Crystal Maiden, 
Enchantress, 
Gyrocopter, Lion, 
Riki, 
Techies, 
Terrorblade, 
Necrophos, 
Invoker.
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.
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.
Gyrocopter
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
Sven
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
Sven
* Heroes that can prevent Sven from farming are very strong against him. Such as Riki and 
Bounty Hunter with their respective invisibility.
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.
Gyrocopter
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, 
Clinkz, 
Drow Ranger, 
Faceless Void, Gyrocopter, 
Juggernaut, 
Meepo, 
Mirana, 
Monkey King, Morphling, Phantom Assassin, 
Phantom Lancer, Riki, 
Shadow Fiend, 
Slark, 
Sniper, Terrorblade, Troll Warlord, 
Weaver.
Sven
* Heroes who thrive on teamfights can be a problem, such as 
Venomancer, Necrophos, 
Centaur Warrunner...
Sven
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: 
Clockwerk, 
Beastmaster.
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.
Sven
* Melee heroes with low mobility can be kited and killed by Viper: 
Treant Protector, 
Kunkka, 
Alchemist, Troll Warlord, 
Wraith King, 
Tiny, Sven.
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.
Gyrocopter
* 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
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 with naturally low mana can be easily shut down by E.M.P.: Sven, Tiny, Wraith King, 
Omniknight
Sven
* Heroes who thrive on teamfights can be a problem, such as Venomancer, Necrophos, Centaur Warrunner...
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.
Gyrocopter
* 
Magnetic Field evades most of Gyrocopter's attacks.
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
* 
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.
Gyrocopter
* 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.
Gyrocopter
* Void Spirit can easily dodge Gyrocopter's {Ability ID:Homing Missile|gyrocopter} with the help of Dissimilate.
* Void Spirit can partly dodge 
Call Down via Dissimilate or move out of its range with Astral Step.
* Gyrocopter has no escape abilities, which benefits Void Spirit's high mobility.
Sven
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Gyrocopter
* 
Blade Fury and 
Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.
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.
Gyrocopter
* 
Mana Break makes Gyrocopter, who has low mana pool, unable to use his abilities that most of his damage output depends on.
* 
Counterspell negates magical damages from Gyrocopter and it can also reflect Homing Missile back to himself.
* Anti-Mage can easily escape from Gyrocopter's attack range and Call Down with 
Blink.
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
* Sven has no easy way to burn 
Refraction charges and needs help from teammates to kill TA successfully.
Gyrocopter
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, 
Queen of Pain, Shadow Shaman (
Shackles), 
Jakiro, 
Pugna, 
Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, 
Witch Doctor, 
Lycan, 
Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, 
Chaos Knight, 
Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
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.
Gyrocopter
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has Pierce the Veil active: 
Luna, Lina, 
Tusk, 
Broodmother, Shadow Fiend, Ember Spirit, Gyrocopter, 
Vengeful Spirit, 
Arc Warden, 
Medusa, Shadow Shaman.
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.
Gyrocopter
* Flak Cannon destroys Phantom Lancer's illusions very quickly.
Additional:
* 
Flak Cannon and Call Down destroy Phantom Lancer's illusions very quickly.
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.
Gyrocopter
* Flak Cannon destroys Terrorblade's illusions very quickly.
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.
Gyrocopter
* Flak Cannon destroys Chaos Knight's illusions very quickly.
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.
Gyrocopter
* Flak Cannon and Call Down will shred Meepo's clones.
* Homing Missile can catch and single out retreating Meepos, making them an easy kill.
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.
Gyrocopter
* Flak Cannon and Call Down can easily clear Naga Siren's illusions.
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.
Gyrocopter
* Heroes with heavy early and mid-game magical damage are also problematic for Phantom Assassin due to being able to easily kill her before she can gain an item advantage over them: Lina, Necrophos, 
Nyx Assassin, Gyrocopter, Jakiro, 
Death Prophet.
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
* 
Doom generally does not impede Sven in almost any way, provided he has activated God's Strength beforehand.
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.
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.
Gyrocopter
* 
Homing Missile can be used to cancel escape attempts with 
Relocate.
* Flak Cannon allows Gyrocopter to attack both, Io and his 
Tethered target, especially when upgraded with Aghanim's Scepter.
* 
Rocket Barrage and Call Down allow Gyrocopter to deal serious damage to both Io and his Tethered target.
Additional:
* Homing Missile can be used to cancel escape attempts with Relocate.
* Flak Cannon allows Gyrocopter to attack both, Io and his Tethered target, especially when upgraded with Aghanim's Scepter.
* Rocket Barrage and Call Down allow Gyrocopter to deal serious damage to both Io and his Tethered target.
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 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.
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
* Storm Hammer interrupts Echo Stomp.
Sven
* Late game heroes are Sven's favourite kind of opponent, such as Anti-Mage, Spectre and Shadow Fiend.
Sven
* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, Vengeful Spirit, 
Dark Willow.
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.
Sven
* Late game heroes are Sven's favourite kind of opponent, such as Anti-Mage, Spectre and Shadow Fiend.
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
Sven
* Heroes with high burst damage and Black King Bar can take down Dark Willow quickly: Phantom Assassin, Sven, Wraith King
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.
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.
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.
Gyrocopter
* 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

Gyrocopter
* Heroes with summons that are destroyed by a fixed number of attacks: 
Undying's 
Tombstone, Gyrocopter's Homing Missile, and Zeus's Nimbus.
Sven
* Storm Hammer stunned can stops Snapfire's 
Mortimer Kisses.
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
* 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.
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.
Gyrocopter
* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, Ursa, Drow Ranger
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
* 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.
Sven
* Heroes that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
Gyrocopter
* 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.
Sven
* Sprout is good for trapping melee carries with no escape abilities: Sven, Alchemist, Lifestealer etc.
Sven
* Heroes with cleave damage: Sven, Magnus, Kunkka.
Gyrocopter
* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina, Lion, Zeus
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
Gyrocopter
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit
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.
Gyrocopter
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: Gyrocopter's Rocket Barrage and Dark Seer's 
Ion Shell are just a couple examples.
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.
Gyrocopter
* 
Laguna Blade ends Gyrocopter very quickly in the early to mid game.
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
* 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.
Gyrocopter
* Flak Cannon rips through Tombstone's zombies.
Additional:
* Flak Cannon enables Gyrocopter to clear the zombies easily.
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.
Sven
* Heroes that deal few, powerful instances of damage, like Oracle, Lion, or Sven, have a hard time breaking through Gravekeeper's Cloak.
Gyrocopter
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter, Kunkka, Magnus and Medusa.
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.
Gyrocopter
*
Life Break and 
Burning Spear usually kills Gyrocopter before he can do much damage to Huskar.
Inner Fire applies a disarm on all enemies, which can be a hindrance to Gyrocopter.
*
