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.
Leshrac
* Oracle's 
Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's 
False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* 
Fortune's End can stop Leshrac from chasing opponents or running away.
Sven
* Heroes who can stun Sven even with an activated Black King Bar can be an issue: 
Clockwerk, 
Beastmaster.
Leshrac
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, 
Jakiro, 
Leshrac, 
Naga Siren, 
Underlord.
Additional:
* Clockwerk naturally builds 
Blade Mail, reflecting Leshrac's high magic damage output back at him.
* 
Power Cogs will prevent Leshrac from reaching Clockwerk's team and dealing large AOE damage to them.
* Power Cogs will also keep Leshrac close, wasting his Diabolic Edict on just Clockwerk.
* 
Battery Assault interrupts Leshrac's long cast times of Split Earth and Lightning Storm.
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.
Leshrac
* Heroes with spell immunity: 
Juggernaut, 
Pangolier, Huskar.
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
* 
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.
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.
Leshrac
* Leshrac's high magic damage is ignored by 
Rage.
* Lifestealer can get in Leshrac's face with Rage and mitigate any other damage taken by Leshrac with 
Open Wounds.
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.
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.
Leshrac
* Nyx Assassin's 
Spiked Carapace will stun Leshrac when hit by any of his AOE abilities.
* 
Mind Flare deals high damage due to Leshrac's high intelligence gain.
* 
Vendetta burns a large amount of Leshrac's essential mana pool.
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.
Sven
* Against her Untouchable, Sven is barely able to hit Enchantress even with his Black King Bar.
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.
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.
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.
Sven
* Heroes who thrive on teamfights can be a problem, such as 
Venomancer, 
Necrophos, Centaur Warrunner...
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.
Leshrac
* 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 that rely on physical damage are ineffective against Dragon Knight due to his high armor: Phantom Assassin,Bloodseeker, Lifestealer, Troll Warlord, Sven
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.
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
* 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
* Primal Roar takes Sven out of the fight completely, even with Black King Bar.
Leshrac
* Heroes who summon multiple units that are not spell immune. 
Nature's Prophet,
Lycan,Beastmaster
Sven
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: 
Terrorblade, Sven, 
Clinkz, 
Windranger, Alchemist, Dragon Knight, 
Legion Commander
Leshrac
* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.
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
* 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.
Leshrac
* Leshrac can easily clear Phantom Lancer's illusions with his huge area of effect damage.
Additional:
* Leshrac's AoE abilities destroy Phantom Lancer's illusions.
* 
Diabolic Edict and 
Pulse Nova require no targeting, thus hitting Phantom Lancer whenever he's nearby.
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.
Leshrac
* Pulse Nova deals an insane amount of damage in an area around him, which can quickly wear down Meepo clones.
* Leshrac can catch multiple Meepos in Split Earth and follow up with the rest of his area damage spells making Meepo unable to get close to Leshrac.
* Diabolic Edict is a strong ability that can wear down a lone Meepo clone quickly.
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.
Leshrac
* Your AoE abilities should make quick work of her spiderlings.
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.
Leshrac
* Heroes with either magical, physical or pure damage burst: 
Bane, 
Ember Spirit, Leshrac, 
Lina, 
Luna, 
Nyx Assassin, Phantom Assassin, 
Skywrath Mage, 
Tinker, Ursa, 
Void Spirit.
Additional:
* Leshrac's AoE abilities make quick work of Chen's creep army.
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.
Leshrac
* As Terrorblade's damage output comes mainly from direct attacks, he will struggle greatly against heroes who have abilities that give evasion, trigger on attack or which can disarm an enemy hero: Centaur Warrunner, 
Hoodwink, Huskar, 
Invoker, Leshrac with 
Nihilism from Aghanim's Scepter, Lifestealer with Aghanim's Scepter upgraded 
Infest, Pangolier, Phantom Assassin, 
Pugna, 
Techies, Windranger etc.
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.
Leshrac
* All of Leshrac's abilities, especially Pulse Nova, can easily deal with Naga Siren's illusions.
* Aghanim's Scepter gives Leshrac access to Nihilism ability, that allows him to turn himself along with Naga Siren and her illusions to turn ethereal. And to make things worse, Nihilism can slow Naga Siren and her illusions, make them more vulnerable to magical damage and unable to fight back while Leshrac moves faster and does not take increased magical damage for it's duration.
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.
Leshrac
* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,Beastmaster
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.
Leshrac
* Heroes that can punish aggressive heroes, such as: Leshrac, 
Shadow Demon, Pugna, 
Death Prophet.
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and 
Zeus.
Leshrac
* Heroes with AoE abilities will hit Slark in Shadow Dance: Lina, Jakiro, Underlord, Leshrac, 
Dark Seer, 
Earthshaker, 
Timbersaw, 
Crystal Maiden.
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
* 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.
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
* 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.
Leshrac
* Io is a hero who needs to be close to it's tethered target to make it effective, and that's where Leshrac gets the advantage thanks to many of his area-of-effect abilities.
* 
Lightning Storm will usually hit both Io and its tethered target since both will be close enough for the lightning to jump.
* Diabolic Edict and Pulse Nova hit all units near Leshrac, meaning he can do colossal damage to both, Io and its tethered target.
Additional:
* Lightning Storm will usually hit both Io and his 
Tethered target since both will be close enough for the lightning to jump. It can then be followed up by Split Earth.
* Diabolic Edict and Pulse Nova hit all units near Leshrac, meaning he can do colossal damage to Io and his Tethered target.
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.
Leshrac
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, 
Viper, Skywrath Mage, Lion, Lina, Venomancer.
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.

* 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
* Storm Hammer interrupts Echo Stomp.
Leshrac
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, Alchemist, Earthshaker, 
Razor, Tinker, Leshrac,

Leshrac
* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,Beastmaster
Sven
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
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
* 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
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
Leshrac
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain
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

* 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

Leshrac
* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, 
Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, 
Keeper of the Light, Invoker, Leshrac, 
Puck.
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
* 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
* 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
* 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 damage output and become less threatening: Phantom Assassin, Sven, Slark, Phantom Lancer.
* You can always stack camps and farm the scepter with Shadow Poison.
Leshrac
* Diabolic Edict and Pulse Nova will tear apart any illusions spawned from 
Disruption
* Split Earth can punish improper usage of Disruption.
* Leshrac does not have any buffs that can be removed by 
Demonic Purge.
Additional:
* Pulse Nova makes quick work of any illusions with amplified damage, and deals damage even if Leshrac is in Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a 
Split Earth for the enemy.
* Disruption does not stop Diabolic Edict and Pulse Nova once they start pulsing, and even worse it provides a safe shelter for Leshrac to keep pumping up his powerful AoE damage onto the battlefield.
* Shadow Demon doesn't have the burst damage to take Leshrac out of the fight quickly, although Demonic Purge can help his allies kill a squishy Leshrac.
Sven
* Heroes that deal few, powerful instances of damage, like 
Oracle, Lion, or Sven, have a hard time breaking through Gravekeeper's Cloak.
Leshrac
* Diabolic Edict and Pulse Nova hit all units around Leshrac, making it very easy for him to kill the 
Summon Familiars.
* Diabolic Edict and Pulse Nova also deal many instances of damage, nullifying 
Gravekeeper's Cloak.
* Split Earth and Lightning Storm makes it difficult for 
Visage to kite Leshrac, even while under the effects of 
Grave Chill.
Sven
* Sven has no easy way to burn 
Refraction charges and needs help from teammates to kill TA successfully.
Leshrac
* Pulse Nova can easily burn Templar Assassin's Refraction charges quickly, and can also hit her while she is invisible in 
Meld.
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
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
Leshrac
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like 
Mirana's 
Sacred Arrow or Leshrac's Split Earth, or combos like Kunkka's 
X Marks the Spot into 
Torrent.
Leshrac
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, Necrophos, Oracle, and Leshrac.
Additional:
* 
Counterspell severely reduces Leshrac's magical damage.Counterspell also impacted reflect Lightning Storm and send back to Leshrac's also affected from movement speed.
* Leshrac already burns through his own mana with Pulse Nova, 
Mana Break will burn through even more.
* Leshrac's high mana pool will increase the amount of damage 
Mana Void does to him when his mana is low.
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.
Leshrac
* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.
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.
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 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.
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.
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.
Leshrac
*
Nether Ward punishes Leshrac's constant mana usage from spamming spells.
Nether Blast nor 
Life Drain easily.
Split Earth can also be hard to land on Pugna for the same reason.
* Leshrac needs to be in the thick of the fight to deal damage, and so cannot escape from
Additional:
* Leshrac needs to be close to target in order to do damage, Pugna can outrun Leshrac with ease due to his superior movement speed.
*
* Leshrac uses huge amounts of mana to do damage, Nether Ward forces him to either not contribute in a fight or kill himself in the process.
