Templar Assassin
[wiki] rating: 2.0 (winrate: 48% pickrate: 6%)Lifestealer
[wiki] rating: 2.0 (winrate: 48% pickrate: 8%)Sven
* Lifestealer excels at killing high health heroes with 
Feast, and Sven is no exception.
* 
Rage stops Storm Hammer from hitting Lifestealer.
* Rage and 
Open Wounds helps Lifestealer survive against Sven's high physical damage.
Invoker
* Rage protects Lifestealer nearly from all of Invoker's spells.
Additional:
* Rage grants immunity from Invoker's spells and can dispel most of the disables such as the armor loss from Forge Spirit and the constant stuns of Cold Snap.
Spectre
[wiki] rating: 1.0 (winrate: 53% pickrate: 16%)Sven
* 
Spectral Dagger hinders Sven's low movement speed, and can be an easy tool to escape against his high damage.
* 
Dispersion makes it harder for Sven to burst down Spectre in one on one fights, and can reflect Sven's high damage back to him or his nearby teammates.
* 
Haunt and 
Radiance disables Sven's 
Blink Dagger.
* 
Desolate's pure damage ignores Sven's high armor.
* Spectre should not attempt to stand up to a full slotted Sven, since she will get shredded.
Clockwerk
[wiki] rating: 1.0 (winrate: 52% pickrate: 10%)Sven
* 
Power Cogs greatly limits Sven's positioning, potentially wasting the duration of 
Black King Bar in a teamfight.
* 
Battery Assault makes it hard for Sven to fight Clockwerk in his Power Cogs.
* Clockwerk's 
Blade Mail forces Sven to avoid attacking while inside Power Cogs, effectively rendering him useless for a few seconds.
Razor
[wiki] rating: 1.0 (winrate: 51% pickrate: 1%)Sven
* 
Static Link saps Sven's insane attack damage, and goes through Black King Bar.
Beastmaster
[wiki] rating: 1.0 (winrate: 51% pickrate: 3%)Sven
* Primal Roar takes Sven out of the fight completely, even with Black King Bar.
Pugna
[wiki] rating: 1.0 (winrate: 51% pickrate: 7%)Invoker
* Because Invoker relies on casting a large amount of spells to contribute to fights, Nether Ward can force him to not cast anything at all or take a large amount of damage to cast spells.
Sven
* Pugna can save allies with both healing or by making them ethereal.
Invoker
* Invoker can use Tornado or Cold Snap to prevent Pugna from channeling 
Life Drain
* A poorly used 
Decrepify on Pugna's allies means Invoker's abilities can be used to deal more damage to it
* Tornado allows Invoker to purge Pugna's Decrepify when it is used defensively
* Special care has to be taken, however, when casting several abilities within the range of a 
Nether Ward
Venomancer
[wiki] rating: 1.0 (winrate: 51% pickrate: 7%)Sven
* Venomancer forces Sven to choose between using his Black King Bar or getting constantly slowed by his poison.
Earth Spirit
[wiki] rating: 1.0 (winrate: 50% pickrate: 8%)Invoker
* Earth Spirit is a dangerous foe to encounter for Invoker in the early stages of the game. Since Invoker needs to gain levels as fast as possible and is not very strong in the early game, Earth Spirit can use his incredible early game power to gank Invoker and ruin his game plan.
* Earth Spirit combines stuns and silences with his spells and can apply them from a great distance. This is bad for Invoker as he is dependent on a smart usage of his spells with 
Invoke and Earth Spirit can disrupt his combos easily.
Troll Warlord
[wiki] rating: 1.0 (winrate: 50% pickrate: 4%)Sven
* 
Whirling Axes (Melee)'s blind makes Sven nearly useless in the early game and allows Troll Warlord to 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.
Silencer
[wiki] rating: 1.0 (winrate: 49% pickrate: 7%)Invoker
* Invoker is heavily dependent on his spells, making him useless during 
Global Silence, as well as interrupting Invoker during his combo.
* 
Arcane Curse is particularly deadly, because Invoker will continuously lose health if he keeps invoking and casting new spells.
* 
Last Word will silence Invoker when he casts Invoke, interrupting his combo.
Weaver
[wiki] rating: 1.0 (winrate: 48% pickrate: 4%)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.
Queen of Pain
[wiki] rating: 1.0 (winrate: 47% pickrate: 12%)Invoker
* Queen of Pain usually outlanes Invoker, giving her team a significant early game advantage while Invoker is still farming.
* 
Blink allows Queen of Pain to escape from Invoker's combo if he doesn't have disables.
Rubick
[wiki] rating: 1.0 (winrate: 47% pickrate: 19%)Invoker
* All of Invoker's abilities scales with his level, thus Rubick possesses great potential in late game by owning any of Invoker's arsenal.
* Fade Bolt counters early push from 
Forge Spirit.
Outworld Devourer
[wiki] rating: 1.0 (winrate: 46% pickrate: 3%)Invoker
* 
Astral Imprisonment allows Outworld Devourer to save himself or ally from Invoker's combo, or remove Invoker from a fight temporarily.
* 
Arcane Orb's pure damage will deal a lot of damage against Invoker's mediocre strength gain.
* EMP is useless against Outworld Devourer by activating 
Equilibrium.
* However, be aware that 
Sanity's Eclipse will most likely not deal any damage at all, due to Invoker's high intelligence gain compared to Outworld Devourer's.
Sven
* Tanky melee heroes that can easily be kited, which allows Outworld Devourer to build charges with Arcane Orb from a distance: 
Sven, 
Underlord, 
Bristleback.
Invoker
* Any heroes with high intelligence, such as 
Invoker and 
Pugna.
Kunkka
[wiki] rating: 1.0 (winrate: 45% pickrate: 6%)Invoker
* 
Tidebringer pressures Invoker easily in lane due to Invoker's low health and armor in the early game.
Enchantress
[wiki] rating: 1.0 (winrate: 45% pickrate: 2%)Sven
* Against her Untouchable, Sven is barely able to hit Enchantress even with his Black King Bar.
Underlord
[wiki] rating: 0.6 (winrate: 55% pickrate: 10%)Sven

Dragon Knight, 
Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.

Death Prophet, 
Riki, 
Drow Ranger.
Bane
[wiki] rating: 0.6 (winrate: 52% pickrate: 5%)Invoker

Medusa, 
Outworld Devourer,

* Heroes with silence: Death Prophet, Riki, Drow Ranger.
Slardar
[wiki] rating: 0.6 (winrate: 51% pickrate: 10%)Invoker
* Invoker's 
Ghost Walk can be countered, however, Invoker could also use abilities like 
Tornado or 
Ice Wall to escape by other means.
Bounty Hunter
[wiki] rating: 0.6 (winrate: 51% pickrate: 5%)Invoker
* Bounty Hunter and 
Slardar both have ultimates (
Corrosive Haze and 
Track) that reveal Invoker through Ghost Walk.
Oracle
[wiki] rating: 0.6 (winrate: 50% pickrate: 10%)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.
Nyx Assassin
[wiki] rating: 0.6 (winrate: 50% pickrate: 3%)Invoker
* Large area-of-effect with delay or require channeling: Enigma, 
Crystal Maiden, Invoker, Shadow Fiend, Pugna, 
Keeper of the Light
* The nature of some abilities turn them into an easy target for a turnover from Spiked Carapace:
* Slow-moving projectiles: 
Skywrath Mage, 
Tinker, 
Necrophos
* Large area-of-effect with delay or require channeling: Enigma, Crystal Maiden, Invoker, Shadow Fiend, Pugna, Keeper of the Light
* Deals damage over time: 
Venomancer, 
Huskar, 
Ember Spirit, Dark Seer, 
Sand King, Doom
Additional:
* Nyx Assassin takes advantage of Invoker's massive intelligence gain and mana pool to do tons of damage using 
Mana Burn, as the spell does more damage based on the target's intelligence.
* Nyx Assassin can simply activate 
Spiked Carapace while under many Invoker's abilities to stun him.
Viper
[wiki] rating: 0.6 (winrate: 50% pickrate: 5%)Invoker
* 
Corrosive Skin makes Viper receive less damage from Invoker's spells
* Viper can harass Invoker with his 
Poison Attack in the early game.
* 
Viper Strike and Poison Attack can kill Invoker easily if Ghost Walk is on cooldown.
Sven
* Melee heroes with low mobility can be kited and killed by Viper: Treant Protector, 
Kunkka, Alchemist, 
Troll Warlord, Wraith King, Tiny, Sven.
Invoker
* Ice Wall and Ghost Walk can be used to kite and escape from Viper.
* 
Chaos Meteor and 
Sun Strike deal heavy damage and can quickly bring Viper down.
* 
Cold Snap, Tornado, and 
Deafening Blast are powerful disables that reduce Viper's effectiveness.
* 
EMP burns Viper's limited mana pool, reducing his potential poison damage.
* Forge Spirits can melt Viper's armor and reduce his durability.
Shadow Shaman
[wiki] rating: 0.6 (winrate: 50% pickrate: 6%)Invoker
* Heroes with long lockdowns: 
Shadow Shaman, Legion Commander.
Puck
[wiki] rating: 0.6 (winrate: 48% pickrate: 6%)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.
Shadow Demon
[wiki] rating: 0.6 (winrate: 47% pickrate: 3%)Sven
* Heroes that lose a great amount of damage output and become less threatening: Phantom Assassin, Sven, 
Slark, 
Phantom Lancer.

* Keeper of the Light's AoE blind can keep Sven from landing hits.
Batrider
[wiki] rating: 0.6 (winrate: 46% pickrate: 2%)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
[wiki] rating: 0.6 (winrate: 45% pickrate: 2%)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.
Undying
[wiki] rating: 0.4 (winrate: 52% pickrate: 7%)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.
Invoker
* Invoker's multiple spells can lock down Undying and disable him from doing much.
Juggernaut
[wiki] rating: 0.4 (winrate: 50% pickrate: 20%)Invoker
* Juggernaut's instant spell immunity from Blade Fury helps him dodge Invoker's combos. He can dispel the disables from Cold Snap and Deafening Blast and dodge the damage from Chaos Meteor, as well as walk through Ice Wall.
* Juggernaut's high DPS allows him to kill split pushing Forge Spirit(s) effortlessly, and his high armor prevents them from being a threat to him.
* However, Invoker can hit Juggernaut with Sun Strike through Blade Fury, making the Tornado > Sun Strike combo a threat if he does not dodge Tornado.
Additional:

Omnislash renders Juggernaut invulnerable to Invoker's spells and can easily take Invoker down.

Pangolier

* Heroes with abilities which have a built-in spell immunity: Lifestealer, 
Juggernaut, 
Pangolier.

Swashbuckle.

Additional:
* 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.

* Sven also has high physical damage, making it easy for him to burst her down.

Earthshaker, 
Monkey King, Shadow Fiend

* In general, heroes such as Lion, 
Silencer, Skywrath Mage, Sven, 
Ogre Magi and others with reliable disables are crucial to killing Techies before they can suicide.
Invoker
* Heroes with summons like 
Broodmother,Enigma, Invoker, 
Nature's Prophet, 
Lycan, 
Visage;or illusions, like 
Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

Diffusal Blade. This is further reduced by the armor bonus from 
Warcry.
Timbersaw
[wiki] rating: -1.0 (winrate: 48% pickrate: 5%)Invoker
* Cold Snap can prevent Timbersaw from using both Timber Chain and Chakram due to the frequent stuns interrupting the lengthy cast animations, as well as stopping him mid-chain. This can negate Timbersaw's attempts to escape or dole out extra ability damage.
* Later in the game, Invoker's heavy magical and pure damage can be difficult to avoid, meaning Timbersaw's armor is less useful.
Legion Commander
[wiki] rating: -1.0 (winrate: 48% pickrate: 14%)Invoker
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
Sven
* God's Strength with Sven's tankiness and item build makes him difficult to take down in Duels.
* Storm Hammer can be used to interrupt Duels (until Legion Commander buys Aghanim's Scepter).
* Sven also has a talent at level 15 that allows Storm Hammer to apply a basic dispel on any enemies hit by it, which can remove the buffs from Overwhelming Odds and Press the Attack.
* Warcry gives a shield to Sven's teammates, which can completely waste Duel's duration depending on how much strength Sven has.
Invoker
* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, 
Ancient Apparition, Zeus, Invoker, Treant Protector

Additional:

Alchemist
[wiki] rating: -1.0 (winrate: 50% pickrate: 3%)Invoker

* Great Cleave and God's Strength devastates Phantasm illusions.
Warlock
[wiki] rating: -1.0 (winrate: 51% pickrate: 7%)Sven
* With God's Strength, Warlock Golem goes down in a matter of seconds. The two weaker golems granted by Aghanim's Scepter will fare worse due to Great Cleave hitting both.

* Heroes who Sniper can kite: Sven, Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.

* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, 
Sniper, Monkey King, Sven.

Necrophos
[wiki] rating: -0.4 (winrate: 52% pickrate: 6%)Sven
* Some heroes, such as Necrophos can be an issue if not initiated onto by Sven first.
Additional:
* 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.
Invoker
* Tornado allows Invoker to purge Necrophos's 
Ghost Shroud, nullifying any benefits he could get out of it
* EMP allows Invoker to burn Necrophos's mana, preventing him to use his abilities constantly

[wiki] rating: 0.0 (winrate: 47% pickrate: 6%)Invoker

Wraith King
[wiki] rating: 0.0 (winrate: 47% pickrate: 6%)Sven

* 
Wraithfire Blast's low cooldown allows Wraith King to stun Sven several times in a team fight.

Winter Wyvern
[wiki] rating: 0.0 (winrate: 48% pickrate: 6%)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.
Invoker
* Cold Embrace is the perfect setup for all his nukes - Chaos Meteor, EMP and especially global Sun Strike.
Death Prophet
[wiki] rating: 0.0 (winrate: 49% pickrate: 2%)Invoker
* Quas-Exort Invoker is also a good matchup due to the fact he has no 
Wex to run faster due to the movement impairment on his stealth. The Forge Spirit and Cold Snap combo doesn't harm her as well since you can drain Invoker's HP with Spirit Siphon which forces him to retreat.
* Silence also prevents Invoker from using Invoke or casting his main spells temporarily. There is no way Invoker can block it unless he has 
Eul's Scepter of Divinity to cyclone himself or has help from allies.
Sven
* God's Strength allows Sven to take down Death Prophet quickly, reducing the damage dealt over time from 
Exorcism.
* Warcry's shield is very useful for Sven and his teammates against Exorcism, which deals physical damage.
Medusa
[wiki] rating: 0.0 (winrate: 49% pickrate: 2%)Sven
* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mystic Snake eats away at Sven's small mana pool.
* Mana Shield negates much of Sven's burst damage.
Invoker
* EMP is a large mana burn nuke which can hit Medusa's Mana shield with enough damage to lose even more mana.
* Deafening Blast disarms Medusa's ability to deal pseudo-AOE damage during teamfights.
* Cold Snap allows the opposing team to repeatedly stun Medusa in short succession, preventing her from successfully casting her ultimate due to its long cast time.
Additional:
* EMP allows Invoker to burn Medusa's mana to weaken 
Mana Shield.
* Medusa's lack of mobility makes her easy to kite with Invoker's spells.
Faceless Void
[wiki] rating: 0.0 (winrate: 50% pickrate: 19%)Invoker
* Time Walk can easily avoid Invoker's combo damage if doesn't have disables.
* Chronosphere will reveal Invoker during Ghost Walk.
* All of Invoker's hidden cooldowns are affected by Time Dilation, so Faceless Void can easily slow him down a lot.
Additional:
* 
Time Dilation prevents Invoker from further invoking for the entire duration of the debuff, as well as massively slowing Invoker based on the large amount of spells he has.
* 
Time Walk will completely negate Invoker's combo damage.
* If Invoker is caught in 
Chronosphere, he will most likely be the primary target due to the large teamfight contribution he can provide.
Sven
* Warcry can absorb damage while allies are trapped in Chronosphere.
Tinker
[wiki] rating: 0.0 (winrate: 50% pickrate: 6%)Invoker
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, 
Gyrocopter, Lion, Riki, 
Techies, Terrorblade, Necrophos, Invoker.
Invoker
* Heroes that can gain vision over trees to catch Tinker: Invoker, 
Shadow Demon, Batrider
Additional:
* Tinker is relatively helpless against Invoker, as his 
Rearm and 
Boots of Travel can be easily interrupted by Invoker's long range disables, even if he blinks away.
Anti-Mage
[wiki] rating: 0.0 (winrate: 51% pickrate: 16%)Invoker
* Anti-Mage's mobility and magic resistance make him nearly impossible to kill alone.
* Invoker's spells cost a lot of mana, and Invoker himself has a lot of mana. This means Invoker and his team are vulnerable to 
Mana Void's heavy damage.
* 
Blink allows Anti-Mage to escape from Invoker's combo if he doesn't have disables.
Sven
* Anti-Mage is fairly fragile, and cannot stand against Sven in a prolonged fight.
* Sven's Black King Bar and low base mana protects against 
Mana Break.
* 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.
Omniknight
[wiki] rating: 0.0 (winrate: 53% pickrate: 1%)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 negate's Sven's massive damage during God's Strength.
Invoker
* Tornado dispels Guardian Angel from multiple targets.
* Guardian Angel is generally useless against Invoker as he primarily relies on magical damage.
* EMP depletes Omniknight's already small mana pool.
* Invoker's many disables keep Omniknight's team occupied until Guardian Angel times out.
Night Stalker
[wiki] rating: 0.0 (winrate: 54% pickrate: 6%)Invoker
* 
Crippling Fear is a good way to shut down and gank Invoker in the early game..
* 
Void deals good damage to Invoker and makes escaping harder.
* With 
Hunter in the Night and Void, Invoker can't get away from Night Stalker and won't be able to catch him with Sun Strike during the night.
Sven
* Night Stalker can't kill Sven quickly while he has the armor bonus from Warcry.
* Sven under the effect of God's Strength and his various physical damage strength items can kill Night Stalker first.
Vengeful Spirit
[wiki] rating: 0.0 (winrate: 54% pickrate: 8%)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.
Broodmother
[wiki] rating: 0.0 (winrate: 57% pickrate: 2%)Invoker
* Broodmother can kill Invoker easily in the early game with her 
Spawn Spiderlings and her spiderlings.
* Broodmother is both an Orchid Malevolence and a 
Nullifier carrier. As she can farm it early, she can kill Invoker easily.
Sven
* Great Cleave clears Spiderlings quickly to increase gold income.
* Warcry shields Sven and his allies against Broodmother and her Spiderlings.
Additional:
* 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 Incapacitating Bite and Orchid Malevolence.
* Warcry and God's Strength allow Sven to easily out-damage Broodmother.
Invoker
* Templar Assassin can easily counter Invoker's last hitting process in the early game with
Refraction. 
Refraction also negates the stun from Cold Snap, since it will need to deal damage in order to apply its stun.
* Additionally, Refraction completely blocks damage from Sun Strike should Invoker try to finish her off, provided she activate Refraction beforehand.
Sven
* Sven has no easy way to burn
Refraction charges and needs help from teammates to kill TA successfully.
