Huskar
* Huskar is often at low health, providing large Thirst bonuses.
* 
Life Break triggers Rupture's damage.
Additional:
* Huskar is often at low health, providing large 
Thirst bonuses to Bloodseeker.
* Life Break can trigger 
Rupture's damage.
* A self applied 
Bloodrage together with Blademail means it's almost suicidal for Huskar to jump on Bloodseeker with Life Break
Naga Siren
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: 
Spirit Breaker, 
Bloodseeker, 
Witch Doctor.
Huskar
* Lina interrupts Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use 
Burning Spear
Additional:
* Lina can interrupt Huskar on the center line because of her attack range, she can constantly be at a long distance, punching Huskar with her hand, while Huskar needs a very close distance to use Burning Spear.
Naga Siren
* Heroes with summons and illusions can find themselves easily bested by Lina, like 
Broodmother, 
Nature's Prophet, 
Chen, 
Terrorblade, 
Naga Siren, 
Visage, 
Wraith King, 
Lycan, 
Phantom Lancer, 
Shadow Shaman.
Huskar
* Heroes with pure damage can kill Huskar when he inevitably gets low on health: 
Outworld Destroyer, 
Silencer.
Additional:
* Outworld Destroyer can dodge Life Break with Astral Imprisonment, leaving him unharmed while Huskar loses HP.
* Sanity's Eclipse can deal massive damage to Huskar before he builds up his 
Berserker's Blood stacks due to Huskar's low mana pool.
Naga Siren
* 
Arcane Orb allows Outworld Destroyer's attacks to deal pure damage that can bypass Naga Siren's armor, and which can clear her illusions in no time.
* 
Astral Imprisonment can be used to harass Naga Siren by reducing her maximum mana and to prevent Naga Siren from escaping with Song of the Siren. Outworld Destroyer can also use Astral Imprisonment to protect himself from Naga Siren.
* 
Sanity's Eclipse will most likely instantly kill Naga Siren along with her illusions. Even if Naga Siren survives Sanity's Eclipse, it's mana allergy debuff will discourage Naga Siren from using her abilities as the mana allergy will heal Outworld Destroyer if she uses them for it's duration.
Huskar
* 
Windrun makes it impossible to hit Windranger with Burning Spears.
* Huskar cannot toggle 
Armlet of Mordiggian to regain health while taking constant damage from 
Focus Fire.
Additional:
* Windranger prevents Huskar from landing Burning Spears by using Windrun.
* Because Huskar tends to be at low health, Focus Fire and Powershot are good abilities against him.
Naga Siren
* As long as Windranger is able to identify the real hero among the illusions, heroes relying on them can be easily tagged with Focus Fire: 
Chaos Knight, Terrorblade, Phantom Lancer, Naga Siren.
Huskar
* 
Blade Fury makes Juggernaut immune to the damage from Life Break and Burning Spears.
* It can be instantly activated the second Juggernaut sees Huskar flying towards him with Life Break, blocking all damage.
* 
Healing Ward effectively negates any damage-over-time from Burning Spears.
* Huskar has no defense against 
Omnislash and takes heavy damage due to his low armor.
Naga Siren
* Blade Fury offers good AoE damage to clear illusions and can hurt the real Naga Siren as well if she chooses to blend in the illusions. 
Diffusal Blade does nothing to Juggernaut either when he uses Blade Fury.
* 
Aghanim's Shard upgraded Blade Fury along with Lv 20 DPS talent will shred all illusions almost instantly, especially when combined with 
Mjollnir, a common item for Juggernaut.
Naga Siren
* Illusion-based heroes are effective against Omnislash and Juggernaut's single-targeted damage: Naga Siren, Chaos Knight, Terrorblade,Phantom Lancer.
Huskar
* Heroes with high magical burst can easily kill Huskar when he is at low health: 
Lion, 
Lina, 
Skywrath Mage
Naga Siren
* Lion may upgrade 
Mana Drain, 
Hex and 
Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.
Additional:
* Both Hex and Mana Drain destroy Naga Siren's illusions in an instant, making it hard for her to teamfight or push against a team with Lion. If Lion chooses the AoE effect talent for Hex or the shard for multi-target Mana Drain, it can negate her pushing potential entirely.
* 
Earth Spike is an AoE disable with good damage. If used well, it can help distinguish the true Naga Siren by the damage they take (illusions take more damage).
Huskar
* Mass Serpent Ward rips apart Huskar quickly due to his poor armor.
* As soon as Huskar jumps in, he will be vulnerable to Shadow Shaman's disables if he does not have 
Black King Bar.
Huskar
* Brewmaster can use Cyclone to disable Huskar's healer for much longer than most other heroes can, to make Huskar vulnerable.
* Huskar has no way to stop Brewmaster from using Primal Split by himself, but can cut a good amount of his high health away if Huskar's team wants to burst Brewmaster down during a different disable.
Naga Siren
* Dawnbreaker can easily clear waves of Naga Siren's illusions from 
Mirror Image with 
Starbreaker, 
Celestial Hammer and 
Solar Guardian.
* Aghanim's Shard upgraded Starbreaker will allow Dawnbreaker to dispel 
Ensnare and freely attack Naga Siren during 
Song of the Siren when combined with Black King Bar, a common item on Dawnbreaker.
* Solar Guardian allows Dawnbreaker to counter any attempts of Naga Siren and rejoin her team with Solar Guardian when they require it. 
Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion while Dawnbreaker is airborne for it's duration, as Naga Siren mainly relies on direct attacks in order to deal damage.
Additional:
* Dawnbreaker can easily clear waves of Naga Siren's illusions from Mirror Image with Starbreaker, Celestial Hammer and Solar Guardian.
* Aghanim's Shard upgraded Starbreaker will allow Dawnbreaker to dispel Ensnare and freely attack Naga Siren during Song of the Siren when combined with Black King Bar, a common item on Dawnbreaker.
* Solar Guardian allows Dawnbreaker to counter any pushing attempts of Naga Siren and rejoin her team with Solar Guardian when they require it. Aghanim's Scepter upgraded Solar Guardian can also give Dawnbreaker's allies evasion while Dawnbreaker is airborne for it's duration, as Naga Siren mainly relies on direct attacks in order to deal damage. Solar Guardian can also be used after Naga Siren uses Song of the Siren near her allies to either escape from or counter-initiate against them.
Huskar
* Huskar's Berserker's Blood provides no protection against Clinkz's physical damage output.
* Huskar has no way to disrupt Clinkz's attacks and no way to kill Clinkz alone, as Clinkz can easily go invisible, teleport away, or even fight back.
* Clinkz will often build the items that counter Huskar and the items he usually builds. These include Black King Bar or 
Monkey King Bar for 
Heaven's Halberd, or a disable item like 
Scythe of Vyse or 
Bloodthorn to prevent him from using 
Inner Fire to disarm.
Huskar
* Ice Blast prevents Huskar from healing with Berserker's Blood and negates any lifesteal, making him significantly weaker in battle.
* Burning Spear and Life Break cost Huskar his own health, killing him under the effects from Ice Blast.
* Huskar often builds Armlet of Mordiggian which can be deadly during Ice Blast.
Additional:
* 
Ice Blast prevents Huskar from healing, regeneration, health gained from activating an Armlet of Mordiggian and will kill him when his health dips below a threshold. This makes it very dangerous for him to use his abilities.
Huskar
* Jumping on Ursa with Life Break is often suicide for Huskar, as he will be immediately bursted down with 
Fury Swipes.
Additional:
* Huskar likes fights with a long duration and is usually at low health, making him vulnerable against Ursa's physical damage.
* Jumping in with Life Break against Ursa is suicide, as Enrage, Overpower, and Fury Swipes will easily shred Huskar.
Huskar
* Warlock Golems do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using Life Break, because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allows Warlock's team to gather their wit and retaliate.
* After using Life Break to jump in, Huskar will not have any means to escape Upheaval. Which since he is an attack-dependent hero, this will nullify his impact in fights.
Huskar
* Chemical Rage mitigates damage from Burning Spear.
Additional:
* 
Chemical Rage negates almost all damage from Burning Spears.
Huskar
* Shadow Demon's 
Shadow Poison can quickly stack to the point where Huskars generally low health is easily finished off.
* Shadow Demon's 
Disruption can turn Huskar's high attack speed and regeneration against him, It also makes him an easy target for Shadow Poison,
* Shadow Demon commonly builds a 
Meteor Hammer, allowing him to land a heavy stun on Huskar
* Shadow Demon's upgraded 
Demonic Purge breaks Huskar, It also pierces Spell Immunity, Without his passive for 7 seconds Huskar quickly falls in battle
* However note that Shadow Demon is a squishy target and you can often overwhelm him if he is alone, But he can still Disrupt you to escape
Additional:
* Shadow Poison can quickly stack up on Huskar, And with his naturally low health you don't need as many stacks to be effective.
* Disruption turns Huskars high attack speed against him, They also have the highest survivability as illusions due to his passive Berserker's Blood, It also allows you to put Shadow Poison stacks on him,
* Dissimulate turns Huskar's burning damage against his team, You can cast it on an ally who is taking a bunch of Burning Spear stacks and cause Huskar to take high amounts of damage as well
* Scepter upgraded Demonic Purge is your most effective weapon against him, It's 7 second Break causes him to quickly die in battle
Huskar
* Quas Exort Invoker has high physical damage in the form of Cold Snap and Forged Spirits that allows him to trade hits with Huskar.
* Although Huskar can dispel Cold Snap with Life Break.
* Sun Strike deals pure damage and pierces spell immunity, and Huskar tends to drain his HP, making him a susceptible target.
Naga Siren
* 
Waveform clear Mirror Image illusions from Naga Siren. And though Ensnare can prevent Morphling from using Waveform to escape, he can easily dispel it with 
Manta Style, a common item on Morphling.
* 
Morph allows Morphling to copy Naga Siren's abilities and combine them with Manta Style, a commong item for Morphling, to destroy Naga Siren's illusions. Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Naga Siren that can do the same and which can also allow Morphling to close the gap on Naga Siren.
Naga Siren
* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Naga Siren is not a hero that likes to go for Black King Bar, and that makes her very vulnerable to Jakiro's damage over time in every phase of the game.
Additional:
* Jakiro's damage over time abilities can clear Naga Siren's illusions and can hurt real Naga Siren even for the duration of Song of the Siren.
* Since Naga Siren is a hero who barely goes for Black King Bar, this can make her very vulnerable to Jakiro's damage over time in every phase of the game.
Huskar
* The damage from Burning Spear can be reduced by turning away from Huskar.
* Bristleback can bait Huskar into using Life Break on him, then turn around and receive very little damage.
Additional:
* Bristleback's tankiness and 
Bristleback allow him to outlast Burning Spears' damage-over-time at almost any point in the game. In addition, if Huskar chooses to cast Life Break on Bristleback, Bristleback can simply turn around before it hits and receive little damage.
* 
Viscous Nasal Goo will reduce Huskar's low armor even further, and 
Quill Spray and 
Warpath will tear him down extremely quickly.
Naga Siren
* Avalanche and Toss combo makes short work of Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Huskar
* Husker is the kind of hero that likes to remain at low health, which is perfect for Queen of Pain to burst with Sonic Wave.
* She should be able to Blink away after he jumps on her with Life Break.
Naga Siren
* Timbersaw's innate durability provided by 
Reactive Armor is very hard to deal with as Naga Siren as she mostly relies on sustained damage rather than burst damage unless if she is played as Nuker.
* Timbersaw's high pure damage and low-cooldown area-of-effect nukes which are 
Whirling Death, 
Timber Chain, 
Chakram and 
Flamethrower from Aghanim's Shard can also destroy Naga Siren's illusions very fast.
* Timbersaw is a common 
Lotus Orb wielder which allows him to reflect Ensnare back at Naga SIren.
Naga Siren
* 
Mortimer Kisses can make quick work of Naga Siren's illusions.
* 
Scatterblast and 
Firesnap Cookie's AoE damage are also decent ways to deal with Naga's illusions.
Huskar
* Huskar’s low health play style put him at extreme risk to 
Sharpshooter's extreme damage. In addition, it breaks Berserker's Blood, nullifying Huskar's power source.
Huskar
* 
Untouchable makes it near impossible to stack Burning Spears.
* 
Impetus' pure damage puts an instant end to Huskar's low-health brinkmanship.
Naga Siren
* Many stacks of 
Sticky Napalm, combined with 
Flamebreak and 
Firefly, allows Batrider to destroy illusions from Mirror Image.
* If Batrider can manage to destroy all illusions from Naga Siren, he will be able to use 
Flaming Lasso on the real one, and will be able to drag her toward his team, potentially preventing Naga Siren from escaping with Song of the Siren.
Additional:
* Many stacks of Sticky Napalm, combined with Flamebreak and Firefly, allows Batrider to destroy illusions from Mirror Image.
* If Batrider can manage to destroy all illusions from Naga Siren, he will be able to use Flaming Lasso on the real one, and will be able to drag her toward his team, potentially preventing Naga Siren from escaping with Song of the Siren.
Naga Siren
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like 
Underlord's 
Firestorm, 
Elder Titan's 
Earth Splitter, 
Enigma's 
Midnight Pulse, 
Zeus's 
Arc Lightning, 
Jakiro's 
Liquid Frost from Aghanim's Shard etc.
Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: 
Weaver, 
Dazzle, 
Bristleback, 
Vengeful Spirit.
Additional:
* Huskar struggles against heroes that output high physical damage due to his low armor. Vengeful Spirit's Wave of Terror and Vengeance Aura help increase the physical damage of her team.
Naga Siren
* Naga Siren's Song of the Siren may be useful but Poof will destroy all of her illusions.
Naga Siren
* Heroes who are reliant on illusions: Chaos Knight, Phantom Lancer, Naga Siren.
Additional:
* Centaur's 
Retaliate will harm all attacking enemies, which will allow Centaur Warrunner to see which is the real Naga Siren.
* A well timed 
Hoof Stomp followed by 
Double Edge will clear all Naga's illusions and prevent Naga Siren from escaping with Song of the Siren.
Naga Siren
* Since Naga Siren is a hero who barely goes for Black King Bar, she is vulnerable to nukers with strong magical damage and big area-of-effect spells in every game more than any other carry heroes: 
Sand King, Jakiro, 
Leshrac, Lina, 
Earthshaker, Zeus.
Naga Siren
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer, Chaos Knight, Naga Siren, Terrorblade.
Naga Siren
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: Spirit Breaker, Bloodseeker, Witch Doctor.
Naga Siren
* Heroes who are reliant on illusions or summons: Chaos Knight, Broodmother, Naga Siren.
Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.
Naga Siren
* Dazzle can instantly destroy all of Naga Siren's illusions from Mirror Image with Aghanim's Shard upgraded 
Poison Touch used on her or any of her illusions.
Naga Siren
* Mirror Image's illusions can easily walk straight at Dazzle and attack him, due to Dazzle's lack of reliable AoE nukes or disables.
* Ensnare roots Dazzle or his allies, making it harder to stay in range of Dazzle's saving abilities.
* Song of the Siren can be used to initiate a fight with superior positioning, potentially zoning Dazzle's high-impact spells out of the fight.
Huskar
* Carries that can out damage Huskar will do well against him: 
Legion Commander, 
Faceless Void, 
Troll Warlord, 
Phantom Assassin.
Additional:
* Whirling Axes (Melee) provides a 60% miss chance, resulting in Huskar's attacks missing a lot of the time if it isn't dispelled.
* Troll Warlord's Fervor ramps up in a very similar way as Huskar's Berserker's Blood: as soon as Huskar has high enough health regeneration, Troll Warlord has a high enough attack speed to negate it.
Huskar
* 
Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: Phantom Assassin, 
Enchantress, 
Huskar, Underlord.
Naga Siren
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Huskar
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, 
Anti-Mage, 
Arc Warden, Chaos Knight.
Huskar
* 
Rage renders Lifestealer immune to the damage from Burning Spears.
* 
Feast makes Lifestealer one of few heroes that can outlast Huskar in a one-on-one fight.
Naga Siren
* Heroes with illusions: Chaos Knight, Naga Siren, Phantom Lancer, Terrorblade
Huskar
* Because Huskar tends to stay at low health to gain the maximum bonuses from Berserker's Blood, it makes him an exceptionally prime target for 
Reaper's Scythe.
Additional:
* Huskar is often at low health, making him easy prey for Reaper's Scythe.
* Ghost Shroud prevents Huskar from stacking Burning Spear, and if Heartstopper Aura stacks are active, can regenerate health lost to existing stacks.
Naga Siren
* Illusions make it difficult for Necrophos to target his Reaper's Scythe correctly, thus giving illusion heroes like Chaos Knight or Naga Siren an edge against Necrophos.
Naga Siren
* 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.
Huskar
* Heroes with spell immunity: 
Juggernaut, 
Pangolier, Huskar.
Naga Siren
* 
Atrophy Aura makes it hard or Naga Siren to farm on lane and damage Underlord with 
Rip Tide in teamfights. And her only way to counter this is by playing Nuker role.
* Firestorm is very useful for clearing Naga Siren's illusions from Mirror Image and Manta Style.
* However, Naga Siren can catch Underlord and his team unprepared with Song of the Siren if he chooses to use 
Fiend's Gate to get to a designated point of the map. Naga Siren can also prevent escaping with Fiend's Gate with Ensnare and 
Reel In from Aghanim's Scepter.

Naga Siren
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: 
Luna's Aghanim's Scepter upgraded 
Eclipse, 
Dawnbreaker's Solar Guardian, 
Axe's 
Berserker's Call,

Grimstroke's 
Soulbind, 
Ink Swell and 
Stroke of Fate, Earthshaker's 
Echo Slam and 
Fissure, 
Puck's 
Dream Coil and 
Waning Rift, 
Winter Wyvern's 
Winter's Curse, 
Magnus's 
Reverse Polarity.
Huskar
* 
Corrosive Haze and 
Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
Naga Siren
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Huskar
* Huskar's low armor and movement speed make an easy target for Chaos Knight to initiate on with 
Reality Rift and 
Chaos Bolt.
* Other than Inner Fire, Huskar has no reliable area of effect ability to clear Phantasm illusions.
* Huskar likes to stay at low health to benefit from his Berserker's Blood, thus making him vulnerable to Chaos Knight's high burst physical damage.
Additional:
* Chaos Bolt can stun Huskar when he jump in with Life break, giving 4 seconds maximum for Chaos Knight to deliver a beatdown.
* Reality Rift further reduces Huskar's low armor, boosting Chaos Knight's damage even more.
* Berserker's Blood offer no protection against 
Chaos Strike, which deal physical damage.
* 
Phantasm can be used to dispel the disarm from Inner Fire.
* Although Huskar can use this to disarm the illusion instead, buying himself some times.
Naga Siren
* Illusion-based and multi-unit heroes can take advantage of Chaos Knight's lack of area damage: Naga Siren, Phantom Lancer, Broodmother
Naga Siren
* Luna's 
Moon Glaives and 
Lunar Blessing can clear waves of Naga Siren's illusions from Mirror Image.
* Once Naga Siren's illusions are cleared with Aghanim's Shard upgraded Moon Glaives, Eclipse can often finish off Naga Siren before she can escape with Song of the Siren.
* A well-timed Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Lucent Ministun talent can be casted at long range and allow Luna to burst down Naga Siren faster and repetively stun Naga Siren, preventing her from escaping with Song of the Siren and 
Town Portal Scroll without getting caught in it's range.
* Luna is a natural Black King Bar wielder unlike Naga Siren who barely goes for it, which allows Luna to freely attack Naga Siren during Song of the Siren and potentially get rid of the most of the damage and crowd-control from Naga Siren.
Additional:
* Luna's Moon Glaives and Lunar Blessing can clear waves of Naga Siren's illusions from Mirror Image, especially when combined with 
Gleipnir and Manta Style. Aghanim's Shard upgraded Moon Glaives can also be used to destroy Naga Siren's illusions and damage the real Naga Siren if they are too close to Luna while also reducing any damage Naga Siren inflicts on Luna for their duration.
* Once Naga Siren's illusions are cleared, Eclipse can often finish off Naga Siren before she can escape with Song of the Siren.
* A well-timed Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Lucent Ministun talent can be casted at long range and allow Luna to burst down Naga Siren faster and repetively stun Naga Siren, preventing her from escaping with Song of the Siren and Town Portal Scroll without getting caught in it's range.
* Luna is a natural Black King Bar wielder unlike Naga Siren who barely goes for it, which allows Luna to freely attack Naga Siren during Song of the Siren and potentially get rid of the most of the damage and crowd-control from Naga Siren.
Naga Siren
* Heroes that create illusions: 
Spectre, 
Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, 
Lone Druid, Chen, Enchantress, 
Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Additional:
* Life Break is almost suicidal when used on Legion Commander, as it invites an instant Duel and Legion Commander herself is a natural 
Blade Mail carrier.
* Huskar's low survivability and mostly on low health make him particularly vulnerable to Legion Commander's high physical damage.
Naga Siren
* Heroes who rely on illusions will see them destroyed easily by Overwhelming Odds: Phantom Lancer, Chaos Knight, Terrorblade, Naga Siren
Naga Siren
* Song of the Siren lasts long enough to prevent a successful 
Duel (but only if Naga wasn't the target).
Huskar
* 
Sprout will not protect Nature's Prophet from Huskar if he has already locked on with Life Break.
* Even a farmed Nature's Prophet is usually not durable enough to fight Huskar alone.
Naga Siren
* Naga Siren is a natural split-pusher. With Rip Tide, she will easily out-push Nature's Prophet, farming his treants in the process.
* Ensnare prevents 
Teleportation. Even if he hides inside Sprout, Song of the Siren lasts long enough to prevent him from escaping.
Additional:
* Naga Siren is a natural split-pusher. With a 
Radiance equipped, she will easily keep the lanes pushed out, therefore keeping backdoor protection enabled and preventing Nature's Prophet from dealing building damage.
* Ensnare can prevent Teleportation. Aghanim's Scepter upgraded Ensnare can also affect Nature's Prophet even if he is spell immune. And Reel In from Aghanim's Scepter can also be used to separate Nature's Prophet from his treant and bring him close to Naga Siren and her team to burst him down.
* Song of the Siren will stop Nature's Prophet from escaping even if he has hidden inside of Sprout. Aghanim's Shard upgraded Song of the Siren can also heal her allies and save them from Nature's Prophet.
Huskar
* Inner Fire can damage and disarm Chen's creeps.
* Burning Spear's high damage over time that grows stronger the more it stacks can force Chen to use Hand of God prematurely, potentially wasting a chance to save his allies during a teamfight.
* Berserker's Blood makes it impossible for Chen and his creeps to kill Huskar.
* Life Break can deal huge damage to Chen and slow him down.
Naga Siren
* Naga Siren can make landing Chen's combo very hard due to her being an illusion hero thanks to Mirror Image.
* Rip Tide can deal big damage to Chen and reduce Chen's armor, as well as easily kill all of Chen's creeps.
* Naga Siren often builds Radiance, which allows her to quickly clear Chen's creeps.
* Ensnare will prevent Chen from escaping.
* With Aghanim's Scepter, Naga Siren can get access to Reel In, which can separate Chen from his creeps and draw him closer to Naga Siren and her team to finish her off. To make things worse, Chen has no way to cancel Reel In on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* Carry or Nuker Naga Siren can often finish off Support Chen before he can have a chance to activate 
Hand of God.

* Carry or Nuker Naga Siren can often finish off Support Chen before he can have a chance to activate Hand of God.
Huskar
* Huskar jumps on the hero without any problems, throwing the 
Summon Spirit Bear away from him and forbidding him to beat, which knocks down the regeneration of Lone Druid from the 
Spirit Link ability, in addition, Huskar instantly deals fatal damage to Lone Druid, in some cases he does not even have time to squeeze the 
True Form

Naga Siren
* Unless Lone Druid purchases a Black King Bar for his Spirit Bear, Ensnare will easily kite the Spirit Bear.
* Song of the Siren allows Naga Siren and her team to completely bypass the Spirit Bear and hunt for the Lone Druid himself when starting a fight.
* Lone Druid's lack of innate AoE capabilities mean that Naga Siren's illusions have no problem against him.
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: 
Lich, Crystal Maiden, Silencer, 
Keeper of the Light, Venomancer, etc.
Naga Siren
* Mirror Image can dispel Frostbite. A similar effect can be achieved with Manta Style, a core item on Naga Siren.
* Song of the Siren can stop Freezing Field regardless of any kind of invisibility as well as allow Naga Siren's team to quickly close the gap on Crystal Maiden.
* With Aghanim's Scepter, Naga Siren can get access to Reel In ability, which can allow her to pull Crystal Maiden toward herself and her team and cancel Freezing Field even through Black King Bar.
Additional:
* Mirror Image can dispel Frostbite.
* Song of the Siren can stop Freezing Field regardless of any kind of invisibility as well as allow Naga Siren's team to quickly close the gap on Crystal Maiden.
* Ensnare allows Naga Siren and her team to quickly catch up with Crystal Maiden and kill her.
* With Aghanim's Scepter, Naga Siren can get access to 
Reel In ability , which can allow her to pull Crystal Maiden toward herself and her team and cancel Freezing Field even through Black King Bar.
Naga Siren
* 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.
Huskar
* Huskar's burn damage from Burning Spear is incredibly strong against Templar Assassin as it completely cancels out her Refraction from the burning over time which results in making her very vulnerable to ganks and harassments, and in turn forcing her out of the lane.
Naga Siren
* Ensnare disables Templar Assassin's invisibility and Blink Dagger (a core item on Templar Assassin), and her illusions will break 
Refraction easily.
Naga Siren
* Sand King and 
Phoenix have many tools to deal with multiple enemies at once, which will work well against a crowd of illusions.
Huskar
* Huskar's high attack speed can counteract 
Fire Spirits, and easily destroy the 
Supernova.
Additional:
* Berserker's Blood will let Huskar easily face down a Supernova with increased attack speed.
* 
Icarus Dive may not be an easy escape from Huskar either as he can chase Phoenix during it with Life Break if Huskar times it right.
* However, Phoenix can buy items which can
Naga Siren
* Song of the Siren does not affect Supernova, which allows her and her team to focus the egg while the enemy team is affected by sleep.
* Phoenix cannot use Icarus Dive for escaping when rooted by Ensnare.
* However, Phoenix has many area-of-effect abilities that allow him to clear Naga Siren's illusions from Mirror Image.
Huskar
* Huskar with Life Break
* Heroes that can remove the Track debuff with their skills:
* 
Abaddon with 
Aphotic Shield and 
Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with 
Press the Attack
* 
Lifestealer with Rage and 
Infest
* Naga Siren with Mirror Image
* 
Omniknight with 
Heavenly Grace
* Oracle with Fortune's End and 
False Promise
* Phantom Lancer with 
Doppelganger
* 
Slark with 
Dark Pact
* 
Ursa with 
Enrage
* Weaver with 
Time Lapse
* 
Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Naga Siren
* Naga Siren with Mirror Image
* Heroes that can remove the Track debuff with their skills:
* Abaddon with Aphotic Shield and Borrowed Time
* Huskar with Life Break
* Juggernaut with Blade Fury
* Legion Commander with Press the Attack
* Lifestealer with Rage and Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with Dark Pact
* Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Additional:
* Bounty Hunter is a single target damage dealer, so he will not fare well against Naga Siren. Even though Bounty Hunter can use 
Track on her, Mirror Image will dispel the effect. Ensnare also reveals invisible units while they're rooted, putting Bounty Hunter at a disadvantage.
Naga Siren
* Song of the Siren is very difficult for Rubick to 
Spell Steal when he is affected by sleep.
* Ensnare and Rip Tide together with some attacks can take Rubick down quickly, due to his low health pool and armor.
* Naga Siren usually buys Diffusal Blade, which may prevent Rubick from using his abilities.
* Mirror Image allows Naga Siren to dodge the incoming stun from 
Telekinesis (when she is not a target), and it can also dispel 
Fade Bolt's damage reduction debuff.
Huskar
* Burning Spear's magical damage is very troublesome for Mars in the laning stage.
* Life Break's percentage-based magical damage bypasses Bulwark, and can also be used to jump in or out of Arena Of Blood.
Huskar
* Sunder can prevent Terrorblade's or an ally's death by swapping health, making damage-over-time abilities inefficient. Heroes that rely on damage-over-time abilities like Venomancer and Huskar will have a hard time against Sunder.
Huskar
* 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.
Naga Siren
* Naga Siren can very easily dispel the 
Reflection with Mirror Image. And Besides Reflection that can be used to detect real Naga Siren, Terrorblade has no other ways to deal with Naga Siren's illusions. And what's worse is that Naga Siren can much easily detect the real Terrorblade due to 
Conjure Image having illusions having different colors. In addition, Terroblade is not a common 
Battle Fury nor Mjollnir wielder to counter this problem.
* Aghanim's Scepter upgraded Ensnare will allow Naga Siren to root Terrorblade even ithrough Black King Bar. And with Aghanim's Scepter, Naga Siren can get access to Reel In ability, which can allow her to pull Terrorblade toward herself and her team and away from his illusions, even through Black King Bar.
* Naga Siren can rapidly damage Terrorrblade and weaken Terrorblade's armor with Rip Tide, which combined with Terrorblade's low health and strength gain can almost completely discourage Terrorblade from even being present in teamfights. Rip Tide can also weaken armor of Terrorblade's illusions and damage them.
* Song of the Siren can be used to save an ally whom Terrorblade has used 
Sunder under the condition Naga Siren is quick enough to do it. And since Terrorblade has no "real" burst damage potential outside from Sunder, Naga Siren will usually have plenty of time to save an allied hero on which Sunder was used. Aghanim's Shard upgraded Song of the Siren can also heal her allies around her for it's duration, which allows Naga Siren to nullify effects of Sunder.
* However, Naga Siren's lack of burst damage can make it difficult for her to burst down Terrorblade before he can use Sunder unless Naga Siren has either Black King Bar or 
Linken's Sphere to protect herself against it or if she is played as Nuker.

Naga Siren
* 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.
Huskar
* Magnus cannot manfight Huskar even with Empower, Berserker's Blood's high attack speed and health regeneration, combined with Huskar's high health and Burning Spear stacks will allow Huskar to kill Magnus before he can kill him.
* From a safe distance, Huskar can surprise and counter Magnus's initiation with Life Break and Burning Spear.
* Burning Spear also deals damage over time, disabling Blink Dagger and preventing him from initiating or escaping.
Naga Siren
* 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.
Huskar
* Since Tidebringer has a 4 second cooldown, Kunkka has little availability to manfight Huskar.
Huskar
* Life Break along with Burning Spear can quickly kill Razor before Static Link steals enough damage for Razor to take down Huskar.
* Berserker's Blood can make stealing Huskar's damage and using it against him somewhat dangerous, as Huskar will be able to inflict more and more Burning Spears rapidly.
Naga Siren
* Even though Naga Siren relies on direct attacks to deal damage for most of the time, Song of the Siren allows her to easily waste 
Guardian Angel.
* Ensnare fully works on targets affected with Heavenly Grace. However, Ensnare is dispellable with any dispel, and so can be dispelled by Heavenly Grace.
* As an agility hero that relies on illusions, Naga Siren is one of the most natural Diffusal Blade carriers, the bane of every hero with a small mana pool. Naga Siren can also buy items that deal magical damage like Radiance, 
Dagon, 
Ethereal Blade, 
Revenant's Brooch, 
Veil of Discord and Gleipnir to attack Omniknight's allies protected with Guardian Angel.
Additional:
* Although Naga Siren relies mostly on physical damage, Song of the Siren can be used to time out Guardian Angel, giving Naga Siren's team an easy opportunity to counter-initiate.
* Radiance allows it's owner to deal magical damage to multiple enemy heroes at once, and since Naga Siren often buys it, Guardian Angel is not a very good ability for protection against Naga Siren.
* Likewise, Nuker build Naga Siren (which primarly consists of items such as Radiance, Ethereal Blade, Dagon and Veil of Discord) can render Guardian Angel useless. Although Nuker is not a role Naga Siren should be playing.
Huskar
* Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* Berserker's Blood and Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.
Naga Siren
* Ensnare and Song of the Siren can be used to cancel both, 
Tether and 
Relocate and to close the distance on Io.
* Rip Tide combined with illusions from Mirror Image often finish off Io before he can save himself with Tether or Relocate.
* 
Spirits's weak area-of-effect makes it a bad tool to deal with Naga Siren's illusions from Mirror Image.
* Once Naga Siren buys Aghanim's Scepter, she can gain access to Reel In, which not only allows her to cancel both, Tether and Relocate, but also to pull Io to herself and her team while he is affected with Ensnare, similarly to Batrider's Flaming Lasso.
* Aghanim's Shard upgraded Song of the Siren can also heal the hero Io and his Tethered targed try to gank.

* Aghanim's Shard upgraded Song of the Siren can also heal the hero Io and his tethered targed try to gank.
Naga Siren
* Mirror Image can be effective since Night Stalker cannot withstand fighting illusions. If he's unable to tell which Naga Siren is real, he will have a hard time landing his 
Void. However, if Night Stalker obtains an Aghanim's Scepter, the upgraded Void will hit and may even locate the real Naga Siren in fights.
Additional:
* Ensnare and Song of the Siren prevents Night Stalker from escaping and ganking during daytime or even nighttime.
* Rip Tide reduces Night Stalker's armor, making him easier to focus down.
* Mirror Image can be effective against Night Stalker, due to his single target abilities.
Naga Siren
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Huskar
* Burning Spears can put Monkey King's 
Tree Dance on cooldown.
Naga Siren
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, 
Riki, Faceless Void, 
Storm Spirit.
Naga Siren
* Heroes who are illusion based, or even heroes who frequently build Manta Style can be cleared quickly by Pangolier's high damage, or lose their damage ouput because of Lucky Shot: Chaos Knight, Naga Siren
Huskar
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Naga Siren
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, Meepo, Crystal Maiden, Dark Willow, Underlord, Naga Siren
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Additional:
* Huskar can easily regenerate lost health from DoT spells through Berserker's Blood rendering them ineffective
* Venomancer has little armor and mobility, and rarely builds Linken's Sphere, so he is quite vulnerable to Life Break.
Huskar
* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, 
Pudge, Huskar, Wraith King, 
Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Naga Siren
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, Riki, Faceless Void, Storm Spirit.
Naga Siren
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, Riki, Faceless Void, Storm Spirit.
Naga Siren
* Heroes with summons and illusions such as Broodmother and Naga Siren, are ill-suited for Wraith King to fight, as he has no source of waveclear.
Huskar
* 
Nyx Assassin can reflect Life Break with 
Spiked Carapace.
Huskar
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, 
Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, Doom, Dawnbreaker. However, this also means they are easily stunned.
Naga Siren
* Nyx Assassin's skillset is mostly single-targeted, therefore he will have difficulties against heroes with illusions and summons: Naga Siren, Broodmother, Lycan, Visage, Phantom Lancer. And to make things worse, Nyx Asassin is not a common Battle Fury, 
Maelstrom, Mjollnir, Gleipnir or Radiance wielder to counter this problem.
Naga Siren
* Heroes with illusions and summons can swarm and overwhelm Bane, who has no area abilities to deal with them outside from Aghanim's Shard upgraded 
Brain Sap: Broodmother, Chaos Knight, Naga Siren, Nature's Prophet, Phantom Lancer, Terrorblade, Visage, 
Warlock, Wraith King.
Naga Siren
* Naga Siren with Mirror Image
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* Riki with 
Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and 
Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* 
Tusk with 
Snowball
* Juggernaut with Omnislash
* 
Brewmaster with 
Primal Split
* Lifestealer with Infest
* Phoenix with Supernova
Naga Siren
* Medusa's 
Split Shot and 
Mystic Snake combined with Mjollnir, a common item for Medusa, will whittle down all of Naga Siren's illusions, including Naga Siren herself.
* Medusa's Stone Gaze can disable Naga Siren even for the duration of Song of the Siren and even if Naga Siren is spell immune, discouraging Naga Siren from even trying to use Song of the Siren to save herself or counter-initiate against Medusa.
Additional:
* Medusa's Split Shot and Mystic Snake combined with Mjollnir, a common item for Medusa, will whittle down all of Naga Siren's illusions, including Naga Siren herself.
* Medusa's Stone Gaze can disable Naga Siren even for the duration of Song of the Siren and even if Naga Siren is spell immune, discouraging Naga Siren from even trying to use Song of the Siren to save herself or counter-initiate against Medusa.
Huskar
* Burning Spear's damage over time can rapidly burn Medusa's mana and health alike.
* Inner Fire can slow and disarm Medusa and also allow Huskar to follow up with Life Break.
Naga Siren
* Heroes that build Diffusal Blade or can fit it well into their item build will also make Medusa much less tanky: Riki, Naga Siren, Terrorblade, Juggernaut, Spectre, Slark.
Huskar
* Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
Huskar
* Heroes with damage over time abilities can quickly eat through Gravekeeper's Cloak charges like Huskar, Jakiro and Queen of Pain.
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Additional:
* Lich is going to have a hard time nuking Huskar because of his high health regeneration from Berserker's Blood.
* Lich is a squishy support without an escape mechanism, making Lich an easy kill thanks to Life Break and Burning Spear.
* Once Huskar has Armlet of Mordiggian, even a maxed out Frost Blast will struggle to finish Huskar off.
Naga Siren
* Heroes that heavily depend on illusions or summons, (Naga Siren, Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.
Huskar
* Huskar can destroy Ember Spirit both on the line and in the game. It will be extremely difficult for Ember Spirit to finish off the creeps, because Huskar will not let him approach them, and if Ember Spirit does come up, Huskar just shuts him up with his Burning Spear and Ember Spirit will have to go to the base or bring himself treatment, or continue to stand and die. In all cases, Ember Spirit will go into negative
Additional:
* Ember Spirit does minimal damage to Huskar until the very late game.
* Huskar can destroy Ember Spirit both on the line and in the game.

In all cases, Ember Spirit will go into negative
Huskar
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.
Huskar
* Weaver cannot Time Lapse out of Huskar's burn damage.
Huskar
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Huskar
* Skywrath Mage's armor and agility gain is very low, so when Huskar's Burning Spears stack they can take him down very quickly at any point of the game.
* Berserker's Blood grants bonuses as Huskar uses Burning Spears to harass Skywrath Mage, granting him attack speed, magic resistance, and strength as health regen, making it possible that Huskar can harass Skywrath Mage out of lane and sustain through his magic burst through staying injured throughout lane, or even the game.
* Life Break allows Huskar to jump onto Skywrath Mage, closing the distance between them and busting him down so he cannot run. This can be combed with Inner Fire, adding a movement speed slow if Aghanim's Shard is applied so Skywrath Mage cannot escape.
Huskar
* Heroes with low armor and little mobility, like Huskar, 
Io, etc. will also have an unfortunate fate.
Naga Siren
* Lycan is a hero focused entirely on single target physical damage and lacks disables or AoE damage. Due to this, he will have difficulties dealing with illusions or Naga Siren's Ensnare.
Naga Siren
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like Underlord's Firestorm, Elder Titan's Earth Splitter, Enigma's Midnight Pulse, Zeus's Arc Lightning, Jakiro's Liquid Frost from Aghanim's Shard etc.
Huskar
* Inner Fire can damage and disarm Enigma's eidolons, which can then be cleared out with Burning Spears.
* Huskar's Burning Spears can deal serious damage over time to Enigma during laning and teamfights, and it can also disable 
Blink Dagger for a long time.
* Berserker's Blood that provides Huskar with magic resistance and bonus health regeneration makes it difficult for Enigma to take down Huskar. Huskar is also a common 
Satanic wielder, which can help him recover from Enigma's Black Hole in case he survives it. Enigma's only source of dealing Pure Damage that can bypass Berserker's Blood. This forces Enigma to buy 
Silver Edge, the only item that can help him against Huskar's Berserker's Blood.
* However, Huskar does not have any way to cancel Black Hole outside from Aghanim's Scepter upgraded Life Break that can force Enigma to attack Huskar if used on him.
Huskar
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Naga Siren
* Naga Siren's illusions from Mirror Image can depush the lanes pushed by the Tempest Double, relieving the pressure.
* Mirror Image can dispel Flux, and the illusions can stop Flux from working to it's full power.
Additional:
* Song of the Siren stops Arc Warden from acting and allows Naga Siren's team to close in on him, past his 
Magnetic Field.
* Mirror Image dispels 
Flux. The illusions created from it also disable the slow from Flux if Arc Warden casts it after Mirror Image.
* Arc Warden's playstyle heavily favors split-pushing, which Naga Siren can compete against with her illusions.
Naga Siren
* Heroes with long cast animations can be continuously interrupted by Battery Assault: Centaur Warrunner, Jakiro, Leshrac, Naga Siren, Underlord.
Huskar
* Clockwerk cannot go head-to-head with Huskar in Power Cogs, as Berserker's Blood and Life Break will destroy him faster than the other way around.
Additional:
* Clockwerk's abilities cannot handle Huskar in a one-on-one fight, even if he gets the jump on him.
Huskar
* Heroes that deal damage over time will also fail to bring down Abaddon and his allies, such as Huskar, Venomancer, or Phoenix.
Additional:
* Huskar's damage over time gives Abaddon the opportunity to shield and heal his allies.
* Borrowed Time also makes Abaddon a hard support to gank, thus negating Huskar's early game dominance.
Naga Siren
* Song of the Siren completely wastes Abaddon Borrowed Time while keeping him in place.
* Naga Siren is able to simply dispel Abaddon's 
Curse of Avernus with Mirror Image before getting hit 4 times consecutively.
* Although Naga Siren's illusions can be easily destroyed by Aphotic Shield, Naga Siren can resolve that issue easily by purchasing 
Heart of Tarrasque to drastically increase her durability. Plus, the said item makes Naga Siren harder to be distinguished from her illusions.
Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Naga Siren
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, Riki, Faceless Void, Storm Spirit.
Naga Siren
* 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.
Huskar
* Heroes who can take advantage of God's Strength being on cooldown are also not great matchups, such as Templar Assassin, 
Morphling and Huskar.
Naga Siren
* 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.
Naga Siren
* Any long duration disables that can pierce through both, Pierce The Veil and Black King Bar are devastating against Muerta: Enigma's Black Hole, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Naga Siren's Aghanim's Scepter upgraded Ensnare and Reel In from Aghanim's Scepter, Jakiro's Aghanim's Scepter upgraded Macropyre, 
Bane's 
Fiend's Grip, Pudge's 
Dismember, Batrider's Flaming Lasso, 
Beastmaster's 
Primal Roar, Grimstroke's Soulbind, Medusa's Stone Gaze, Magnus's Reverse Polarity.
Huskar
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a 
Concussive Grenade and a 
Hurricane Pike in order to avoid the Life Break of Huskar
Additional:
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a Concussive Grenade and a Hurricane Pike in order to avoid the Life Break of Huskar
Naga Siren
* Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Naga Siren
* 
Flak Cannon and Call Down can easily clear Naga Siren's illusions.
Huskar
* 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.
Naga Siren
* 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.
Huskar
* Huskar can burn down Dragon Knight's health quickly during the early to mid game, but is not as effective during the late game. However, Life Break remains a constant threat due to the slow and percentage-based damage.
Additional:
* Huskar can negate Dragon Knight's passive with multiple trades of Burning Spear.
Huskar
* Heroes with illusions can overwhelm Huskar: Phantom Lancer, Anti-Mage, Arc Warden, Chaos Knight.
Huskar
* Huskar does not need any mana to fight Anti-Mage as most of his skills cost HP instead. He is a good counter to take away Anti-mage's farm in early to mid-game. He, however, struggles to kill Anti-Mage in the late game.
Additional:
* Huskar is not very reliant on mana to cast his spells, therefore, 
Mana Break is not very effective against him.
* Huskar also has low mana pool, he will take less damage once his mana pool is completely depleted. 
Mana Void is also ineffective against him.
* Huskar comes online earlier than Anti-Mage, and can take over the game before Anti-Mage can farm up.
Naga Siren
* Keeper of the Light can stall pushes with 
Illuminate. This makes him strong against pushing heroes: Terrorblade Naga siren Nature's Prophet and Anti-Mage
Huskar
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.
Huskar
* Heroes who rely on basic attacks will suffer from Laser: Phantom Assassin, Wraith King, Huskar.
Naga Siren
* Illusion heroes, such as Naga Siren, Phantom Lancer, Chaos Knight, Terrorblade will become strong against Tinker in the late game. Without Aghanim's Scepter Tinker is forced to defensively disarm heroes with Laser, leaving illusions free to deal physical damage which Tinker's low armor makes highly effective. In addition, Mjollnir or Battle Fury, two common pickups against illusion heroes, don't work well on Tinker at all.
Huskar
* Spirit Breaker's stuns pierce spell immunity, making him a good choice against heroes that heavily rely on Black King Bar; Huskar
Naga Siren
* Heroes with long-lasting, undispellable debuffs will pinpoint the true Naga Siren: Spirit Breaker, Bloodseeker, Witch Doctor.
Huskar
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion, Huskar, Shadow Shaman, Visage, 
Undying, Jakiro.
Naga Siren
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan, Wraith King.
Huskar
* Carries that can out damage Huskar will do well against him: Legion Commander, Faceless Void, Troll Warlord, Phantom Assassin.
Naga Siren
* Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, Slark, Riki, Faceless Void, Storm Spirit.
Naga Siren
* Mirror Image's illusions increase Echo Slam's damage.
Additional:
* Earthshaker's strong AoE abilities can clear Naga Siren's illusions, or at least make it easier to distinguish the real one by the damage they take.
* Echo Slam deals more damage against more enemies, which can be devestating against Naga Siren and her illusions.
Huskar
* Earthshaker's stuns will rarely save him once Huskar has initiated on him with Life Break.
* A full initiation combo will not kill Huskar, only lower his health and increase his attack speed.
Huskar
* His 
Poison Attack is very useful against Huskar, since he tends to stay at low health.
* 
Nethertoxin disables passive skills like Berserker's Blood.
* It is dangerous for Huskar to jump on Viper because 
Corrosive Skin and 
Viper Strike with the slowdown of movement and attack speed which usually will be deadly for Huskar.
Additional:
* Viper Strike can disable Berserker's Blood, which Huskar relies upon for attack speed and healing.
* The damage from Burning Spear and Life Break is largely absorbed by Corrosive Skin. It also will return some damage, making it risky to use Burning Spears in the laning stage.
* Because Huskar wants to be on low health for Berserker's Blood, he is particularly vulnerable to Poison Attack.
Naga Siren
* Naga Siren can easily disjoint, and dispel Corrosive Skin with Mirror Image.
* Since Viper is mostly a single-target hero, he will not have almost any chance against Naga Siren because she is an illusion based hero.
* Viper has no burst damage, so Naga Siren will have plenty of time to use Aghanim's Shard upgraded Song of the Siren heal her allies before Viper can finish them off.
