Lina
* Squishy heroes (
Io, 
Crystal Maiden, 
Lina...), as Earth Spirit can deal tons of damage with Magnetize.
Tusk
* 
Boulder Smash can return Tusk after his initiation.
* 
Geomagnetic Grip prevents Tusk from using Snowball to escape.
Lina
* 
Doppelganger can be used to easily dodge Light Strike Array if timed correctly.
* While Lina can clear Phantom Lancer's illusions with her abilities, Phantom Lancer can quickly deplete Lina's mana pool with his illusions and deal massive damage from it simultaneously since Phantom Lancer is a natural 
Diffusal Blade carrier.
Tusk
* Doppelganger allows Phantom Lancer to dodge an incoming snowball.
* Phantom Lancer usually buys a Diffusal Blade, which is very effective against Tusk's low mana pool.
* Phantom Lancer usually buys 
Manta Style which can also dodge an incoming snowball, much like Doppelganger.
Lina
* 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.
Lina
* Heroes with low mobility that rely on spells: 
Zeus, Lina, Crystal Maiden.
Tusk
* Durable heroes can stand against Tusk during 1v1: 
Axe, 
Dragon Knight, 
Night Stalker, 
Centaur Warrunner, Wraith King and more.
Lina
* 
Arcane Curse makes it too difficult Lina from using her abilities, preventing her from building up Fiery Soul stacks without causing harm to herself.
* 
Last Word and 
Global Silence are great against Lina for the same reason, as well as interrupting her combos and preventing her from casting spells.
Lina
* 
Spectral Dagger and 
Haunt allow Spectre to get close to Lina.
* 
Desolate is very strong against Lina, who's usually a bit isolated in fights because of her high attack and cast range.
* 
Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn on her afterwards.
Additional:
* Spectre can very easily close the distance on Lina with Haunt and Spectral Dagger, and due to Lina's abysmal mobility without a 
Blink Dagger and terrible health pool and armor, Lina easily gets slaughtered due Desolate.
* Dispersion can mitigate a good portion of Lina's burst damage, allowing Spectre to turn against her afterwards.
Lina
* 
Light Strike Array has a long delay, making her vulnerable for Ursa's burst.
* Enrage can protect Ursa against Lina's high magical burst.
Tusk
* 
Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for Blink Echo Slams.
Tusk
* 
Static Link drains Tusk's base damage, and it also reduces the critical damage output from 
Walrus PUNCH!.
* 
Plasma Field and 
Eye of the Storm allow Razor to chase Tusk after he uses Snowball.
Lina
* Ember Spirit absorbs quite a large amount of magical damage with its 
Flame Guard, and in addition dodges the abilities of 
Dragon Slave and Light Strike Array with its 
Sleight of Fist
Additional:
* Ember Spirit absorbs quite a large amount of magical damage with its Flame Guard, and in addition dodges the abilities of Dragon Slave and Light Strike Array with its Sleight of Fist.
Lina
* 
Dark Pact can be cast during the cast animation of Light Strike Array and dispel its stun.
* 
Pounce allows Slark to close the gap to Lina.
* 
Shadow Dance prevents Lina from killing Slark with her Laguna Blade when his HP gets low.
Tusk
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: 
Anti-Mage, 
Earth Spirit, 
Faceless Void, 
Magnus, 
Mirana, 
Monkey King, 
Morphling, 
Pangolier, 
Phantom Assassin, 
Phoenix, 
Puck, 
Queen of Pain, 
Riki, 
Sand King, 
Spirit Breaker, 
Timbersaw, 
Tusk.
Lina
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, 
Lion, Zeus
Lina
* Dragon Slave is easy to steal, and provides Rubick with a useful nuke.
* Light Strike Array serves as a cheap nuke as well as a crowd control ability.
* Rubick uses the fixed 0.15 second cast time when casting Light Strike Array, much faster than Lina herself.
* Rubick can gurantee a stun by throwing the victim into the area with 
Telekinesis, extending the overall lockdown duration.
* 
Laguna Blade is an awesome ultimate that gives huge burst damage.
* 
Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to a whopping 660/882/1134(830/1162/1494) (and even more so with 
Aghanim's Scepter), without considering spell amplification from items.
* Laguna Blade is an intelligence hero with no regen ability, and casting Laguna Blade back to Lina can result in her unexpected sudden death, or severly hinder her presence in the rest of teamfight. Nevertheless, the skill can also be cast on other squishy heroes or help bursting down enemy carries.
* Light Strike Array and Laguna Blade has a short cast range, and Rubick can extend its range thanks to Arcane Supremacy.
Lina
* 
Time Walk will easily backtrack Lina's burst damage (especially Laguna Blade) if not timed correctly.
* During 
Chronosphere, squishy heroes like Lina will be main target of Faceless Void in his ultimate.
Lina
* Sven has a high health pool and is a natural 
Black King Bar holder and is very hard to kill for Lina.
* Sven also has high physical damage, making it easy for him to burst her down.
Tusk
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.
Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like 
Batrider with 
Flaming Lasso, 
Pudge with 
Meat Hook and 
Vengeful Spirit with 
Nether Swap.
Tusk
* 
Sticky Napalm makes it difficult for Tusk to hold his own on lane.
* An ill-timed and ill-positioned 
Snowball will give Batrider a free counter-initiation with Flaming Lasso if Batrider is far enough to avoid the stun from the Snowball.
Additional:
* Sticky Napalm makes it difficult for Tusk to hold his own on lane.
* An ill-timed and ill-positioned Snowball will give Batrider a free counter-initiation with Flaming Lasso if Batrider is far enough to avoid the stun from the Snowball.
Tusk
* 
Shadow Demon, 
Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
Lina
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: 
Keeper of the Light, Lina, Lion, Zeus.
Additional:
* 
Rage protects Lifestealer from all of Lina's abilities. However, Lina can paritally counter this if played as Carry, a common role for Lina.
* 
Open Wounds from 
Aghanim's Shard can severely slow down Lina and allow Lifestealer and his allies to recover themselves by attacking her.
* Aghanim's Scepter upgraded 
Infest can be used to disarm Lina even if she is spell immune, rendering her unable to maximize the effect of her 
Fiery Soul and force her to use her abilities more often than intended. And Lina's only way to counter this is with 
Linken's Sphere
Lina
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Lina
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - 
Sniper, 
Drow Ranger, Lina, 
Rubick, etc.
Lina
* Heroes with long animations can be frequently interrupted with Cold Snap: 
Earthshaker, Monkey King, 
Shadow Fiend Lina
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Lina
* 
Mind Flare does tons of damage against Lina because of her high intelligence.
* 
Vendetta can deal heavy damage to Lina while also burning her mana, preventing Lina from casting her abilities.
* 
Spiked Carapace can easily be used to counter Lina's abilities because of their long cast animation, and could probably kill Lina outright if Laguna Blade is reflected. However, Lina can counter this with 
Eul's Scepter of Divinity, a common item on Lina.
Lina
* Heroes who build Black King Bar as either core or situational item will be able to fight back against Nyx Assassin and freely attack him as Spiked Carapace cannot pierce spell immunity at all: Axe, Broodmother, 
Dawnbreaker, 
Enigma, 
Huskar, 
Jakiro, 
Legion Commander, Lina, 
Luna, Lycan, 
Slardar, 
Slark, 
Troll Warlord, 
Witch Doctor.
Tusk
* 
Glimpse can return Tusk to where he was after using Snowball.
* 
Static Storm prevents Tusk from escaping with Snowball and when upgraded with Aghanim's Scepter, it will also prevent him from using items.
Tusk
* Tusk with Snowball
* 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
Lina
* Puck can dodge Lina's Dragon Slave and Light Strike Array with his Phase Shift skill, which helps him avoid combining these abilities with Laguna Blade and avoid burst damage from Lina.
* Puck forbids Lina to use her abilities with the 
Waning Rift ability, which will help her teammates survive and even give them the opportunity to kill her.
Additional:
* Puck can dodge Lina's Dragon Slave and Light Strike Array with Phase Shift. A good Puck player can even dodge Laguna Blade, as it has an invisible projectile, therefore avoiding all the burst damage from Lina.
* Puck forbids Lina to use her abilities with Waning Rift, which will help Puck's teammates survive and even give them the opportunity to kill her.
Tusk
* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, 
Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.
Lina
* Templar Assassin can outmatch Lina on the center line thanks to her own 
Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her.
* 
Refraction is good defense against Lina's burst damage. But remember that Lina can partially counter this with Dragon Slave's damage over time.
Additional:
* Outlanes Lina on the center line thanks to her own Psi Blades, which is why the advantage of Lina's long-range attacks become turned against her
* Closes from Lina's magic attacks with her own Refraction, which is why Lina can't make her combination: Light Strike Array, Dragon Slave, Laguna Blade and kill Templar Assassin quickly
Tusk
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a 
Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, 
Bounty Hunter, Riki, 
Warlock.
Lina
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than 
Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.

Tusk
* Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH!'s very high physical damage output can easily kill Sniper instantly due to his low health and armor.
Lina
* Dragon Slave deals reliable magic damage during the laning phase against Mars.
* Lina's Eul's Scepter of Divinity and Light Strike Array combo can interrupt Mars from being disruptive for a decent amount of time and leave him vulnerable for follow up stuns.
* Laguna Blade deals massive magical damage, and pure damage with Aghanim's Scepter.
Tusk
* Snowball can protect Tusk and his teammates from a Spear of Mars' stun after an Arena of Blood, and with proper targeting, even bring them out of the Arena. This is especially noticeable in the earlier stages of the game before allies buy Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out.
* Tag Team is a constant threat to Mars in-lane, as it deals significant damage and slow, making Bulwark slightly ineffective.
* It is worth noting that Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.
Lina
* Lina can outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the attack range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold.
* Lina can defeat Shadow Fiend with the combination of her abilities on lane and during teamfights: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying items for extra strength and health like 
Satanic, which is why Lina's strong magic damage is enough to kill him quickly.
Additional:
* Outlanes Shadow Fiend on the central line, due to the fact that Lina's attack range exceeds the range of Shadow Fiend, which makes it difficult for him to fend off her attacks and approach creeps, thus Lina has more level and gold
* Defeats Shadow Fiend` from Burst with a combination of skills: Light Strike Array, Dragon Slave, Laguna Blade, Shadow Fiend does not have a large pool of health before buying an item: Satanic , which is why Lina's strong magic damage is enough to kill him quickly
Tusk
* Shadow Fiend's lack of mobility and low base health make him an easy target for early ganks.
Lina
* Being a hero with low health and abysmal mobility, Lina can nuke her down easily.
* Since Crystal Maiden's 
Freezing Field is a channeled ability, Lina can use her Light Strike Array to cancel it easily.
Tusk
* Snowball allows Tusk to easily cancel Freezing Field from a safe distance without putting himself in any danger.
* Walrus PUNCH! is most certainly a high enough damage nuke to easily kill off Crystal Maiden.
* Ice Shards can prevent the already immobile Crystal Maiden from escaping, making her an easy kill for either Tusk or a teammate.
Additional:
* Crystal Maiden's low health and armor make her an easy target for Walrus PUNCH!
* Tusk's Snowball can protect allies and cancel Freezing Field.
* Snowball and Walrus PUNCH! can interrupt Freezing Field.
Lina
* Venomancer has low health, which makes him vulnerable to Lina's heavy magic damage.
* Fiery Soul attack speed bonus removes 
Plague Wards easily in all stages of the game.
Tusk
* Snowball can be used to save allies or himself during 
Venomous Gale and 
Poison Nova.
* Venomancer lacks mobility and has low base health, so he can be killed by Walrus PUNCH!
Lina
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use 
Hand of God.
Additional:
* Lina's high damage burst from Dragon Slave, Light Strike Array and Laguna Blade can easily kill Chen's allies or Chen himself before he can use Hand of God.
Tusk
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, 
Clinkz, Sniper, Slark, Phantom Assassin, 
Void Spirit, 
Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Lina
* 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.
Tusk
* Walrus PUNCH! can interrupt 
Black Hole and it can pierce spell immunity and neither Black King Bar nor Linken's Sphere can protect Enigma from Walrus PUNCH! as Walrus PUNCH! is an auto-cast ability.
* In pretty much any phase of the game, Tusk's abilities can easily cancel Black Hole and disrupt Enigma's positioning.
Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with Flaming Lasso, Pudge with Meat Hook and Vengeful Spirit with Nether Swap.
Lina
* Pudge has low armor and mobility, making him suspectible to her physical attacks (if Lina is the carry).
* Because 
Dismember is a channeled ability, it can be canceled through Light Strike Array within a distance.
Tusk
* Tag Team easily overwhelms Pudge, as he has low armor, which when combined with heroes with strong physical damage and Pudge's slow speed, it becomes for Pudge difficult to escape.
* Snowball can save a Dismembered ally and stop Pudge's Dismember.
* Walrus PUNCH! will removes a big chunk of Pudge's health and stun him.
* Pudge usually can't stand toe to toe against Tusk and his allies in the early game.
Lina
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has 
Pierce the Veil active: Luna, Lina, Tusk, Broodmother, Shadow Fiend, Ember Spirit, 
Gyrocopter, Vengeful Spirit, 
Arc Warden, 
Medusa, Shadow Shaman.
Tusk
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has Pierce the Veil active: Luna, Lina, Tusk, Broodmother, Shadow Fiend, Ember Spirit, Gyrocopter, Vengeful Spirit, Arc Warden, Medusa, Shadow Shaman.
Lina
* 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.
Tusk
* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, Lifestealer.
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with 
Death Ward and Bane's 
Fiend's Grip.
Tusk
* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.
Additional:
* Bane has low mobility and health, making him an easy target for Walrus PUNCH!
* Walrus PUNCH! can be used to cancel Fiend's Grip if he is not the target.
Lina
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress's creeps quickly.
Additional:
* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
* 
Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Lina
* 
Moonlight Shadow does little good against Dragon Slave and Light Strike Array.
* Lina's damage burst can quickly kill Mirana's teammates before she saves them with Moonlight Shadow.
Additional:
* Eul's Scepter of Divinity is an item Lina commonly buys, which in combination with and Light Strike Array can disable Mirana if she tries to Leap away.
* Laguna Blade's magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage takes advantage of Mirana's below average health.
Lina
* Light Strike Array catches Morphling while he jumps in from 
Waveform and also prevents Morphling from using his abilities.
* Laguna Blade can kill Morphling quickly before he shifts into 
Attribute Shift (Strength Gain).
Lina
* Laguna Blade is one of the best tools to kill Terrorblade before he can use 
Sunder due to its high magical damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.
* Lina commonly buys items that allow her attacks to deal magical damage to Terrorblade that can ignore his high armor, like 
Gleipnir, 
Monkey King Bar or 
Revenant's Brooch.
Additional:
* Laguna Blade is one of the best tools to kill Terrorblade before he can use Sunder due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.
Lina
* Laguna Blade ends Gyrocopter very quickly in the early to mid game.
Tusk
* Ice Shards can easily interfere with Rolling Thunder, making him stuck inside the arc and wasting his ultimate. Do not panic and use Shield Crash to get out of that position.
* Snowball helps Tusk and his allies follow a fleeing Pangolier, keep in mind that the Pangolier can always counter-initiate with his Rolling Thunder.
* Walrus PUNCH! deals heavy damage even during his Rolling Thunder.
Lina
* Lina has very high magic burst damage to use against the low-health-pool Luna. Laguna Blade can also be upgraded with Laguna Blade damage is Pure and pierces Spell Immunity to bypass Black King Bar, making Lina even more of a threat. Luna however, can easily counter this problem with Linken's Sphere, which is a common item for her.
* For the same reasons, Lina makes a very powerful ally for Luna when they are in the same team.
Lina
* Lina's damage burst can quickly kill Clinkz before he saves them with 
Skeleton Walk.
* Fiery Soul attack speed bonus removes 
Burning Army easily in all stages of the game.
Lina
* Light Strike Array and Dragon Slave allows Lina to destroy trees, countering 
Nature's Guise and 
Eyes in the Forest.
* Lina has many tools to bypass 
Living Armor's protection.
Lina
* Storm Spirit can quickly close the distance with Lina using 
Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array
Additional:
* Storm Spirit can quickly close the distance with Lina using Ball Lightning. In addition, Ball Lightning can be used as a way to dodge the abilities of Dragon Slave and Light Strike Array
Lina
* Lina can win on a line against Storm Spirit because of the range of her abilities and attacks, and Storm Spirit will be forced to survive on such a line, not farm
Tusk
* Tusks damage/stun is enough to obliviate Storm Spirit before he can do anything.
* Tusk is a common Blink Dagger carrier, and once he reaches Level 18, Walrus PUNCH! deals roughly half of Storm Spirit's health alone, It also stuns for a long enough time for Tusk to Snowball Storm Spirit, stunning him even more, If that hasn't finished him off, the damage from Ice Shards probably will. Combined with Tag Team, which adds bonus damage to Tusks attacks, Storm Spirit is unlikely to survive Tusk initiating on him
* Walrus PUNCH is even more potent if he uses a 
Silver Edge instead
* However while Ball Lightning doesn't disjoint Snowball, if used before Tusk hits with Snowball, prevents the stun and damage from being applied
Lina
* 
Ghost Shroud is not a good defensive ability against Lina as all of her abilities deal magical damage.
* Lina has a very long range of attack, which completely overlaps the range of 
Death Pulse and 
Heartstopper Aura.
* However, once Necrophos gets Aghanim's Shard, he will gain access to 
Death Seeker which will allow him to turn into a larger Death Pulse that can be used to close the gap on Lina and kill her if she is not careful.
Additional:
* Laguna Blade's damage as well as damage from all of Lina's abilities will be greatly amplified during Ghost Shroud.
Lina
* Dragon Slave will make quick work of the spawned illusions from Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Light Strike Array for the enemy.
* Shadow Demon doesn't have the burst damage to take Lina out of the fight quickly, although Demonic Purge can help his allies kill a squishy Lina.
Lina
* 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.
Lina
* Lina builds 
Shadow Blade (and upgrades it into a Silver Edge), which makes it hard for Ancient Apparition to land his abilities.
* Laguna Blade can kill Ancient Apparition easily due to his low health pool and lack of mobility.
Lina
* 
Guardian Angel is generally useless against Lina as she primarily relies on magical damage. Lina can also dispel it with Eul's Scepter of Divinity as she is a hero who often goes for it. Eul's Scepter of Divinity can later be upgraded into 
Wind Waker, which will allow Lina to escape from Omniknight.
* Laguna Blade can often finish off Omniknight's allies before he can save them with 
Purification and 
Repel. This can become even worse once Lina picks Laguna Blade damage is pure and pierces spell immunity talent, which will allow it to ignore both, any form of spell immunity and Guardian Angel.
Tusk
* Snowball negates 
Rupture and protects Tusk allies when Ruptured.
Tusk
* Snowball and Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.
* Tag Team allows Tusk to slow her down and land a killing blow on her.
* Walrus PUNCH! slows Drow Ranger and deals a huge amount of damage to her, due to her low health (and low armor without Marksmanship, since Tusk can quickly close the gap to Drow Ranger).
Lina
* Light Strike Array can catch Meepo and his clones off-guard if he tries to gank Lina with 
Earthbind & 
Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
Lina
* 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.
Lina
* 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.
Additional:
* Lina can easily prevent Nature's Prophet's Teleportation escape attempts with Light Strike Array, and can clear Sprout's trees instantly.
* Lina's Dragon Slave and Light Strike Array can kill Nature's Prophet's Treants.
Lina
* Abilities that can destroy trees can give Hoodwink a disadvantage: Timbersaw, 
Windranger, Lina.
Tusk
* Tusk can 
Walrus Kick Monkey King out of Wukong's Command.
Additional:
* Tusk can Walrus Kick Monkey King from 
Wukong's Command, making his ultimate useless.
Lina
* 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.
Lina
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)
Additional:
* Laguna Blade can kill Dazzle quickly before he casts 
Shallow Grave.
Lina
* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina
Lina
* 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.
Lina
* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.
Additional:
* Light Strike Array cancels out Death Ward from a long distance.
Tusk
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Lina
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Lina
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, 
Underlord, Spirit Breaker.
Tusk
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.
Lina
* Heroes who rely on armor or evasion to survive can easily be bursted down, like Phantom Assassin, Terrorblade, Underlord, Spirit Breaker.
Lina
* 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.
Lina
* Any hero with high attack speed will be a threat to Phoenix when it initiates, as they can easily tear down a Supernova, perhaps even while debuffed by Fire Spirits: Juggernaut, Clinkz, Troll Warlord, 
Beastmaster, Lina.
Lina
* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).
Tusk
* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).
Additional:
* Walrus PUNCH! makes Legion Commander lose 
Duel easily, especially when she doesn't have 
Blade Mail. Tusk can also snowball dueled allies, preventing them from taking damage for a large portion of the duel's duration.
Lina
* 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.
Lina
* 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.
Lina
* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Tusk
* Pugna's low health and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.
Lina
* Fragile support heroes are all ideal targets for the Phantom Assassin. Heroes such as Lina and Witch Doctor are all prime targets that may not be able to react quickly and fight back due to Phantom Assassin's sudden appearance.
Lina
* Laguna Blade is one of the best tools to kill Phantom Assassin before she can do anything in early-to-mid game due to its high magical (pure with Laguna Blade damage is Pure and pierces Spell Immunity talent) burst damage.
* 
Blur offers no protection against Lina's abilities. Likewise, Lina can counter Blur's evasion by buying either Silver Edge or Monkey King Bar.
* Lina just has to be careful about 
Fan of Knives from Aghanim's Shard and 
Coup De Grace, as Fan of Knives can deal pure damage to Lina and disable Fiery Soul awhile Coup De Grace can deal serious damage to her even if she is spell immune, which may force Lina to buy 
Ethereal Blade to deal with Phantom Assassin.

Lina
* Heroes with abilities that can pull Lina out of position can easily bring her to their team mates, like Batrider with Flaming Lasso, Pudge with Meat Hook and Vengeful Spirit with Nether Swap.
Lina
* Lina can burst Vengeful Spirit down, provided she can land Light Strike Array before Vengeful Spirit lands her Magic Missile.
* Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.
Tusk
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, Bounty Hunter, 
Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, Magnus etc.
Lina
* Light Strike Array in combination with Dragon Slave can easily clear Broodmother's spiders.
* Laguna Blade offers extensive damage that can kill Broodmother early on or before she is able to use Insatiable Hunger in attempts to salvage a fight.
Lina
* Both Lion's 
Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Lina
* Lina is a common Eul's Scepter of Divinity carrier which can waste some duration of Borrowed Time and following up with Laguna Blade if timed correctly.
Lina
* Heroes that can close the gap can easily chase Lina down, such as Timbersaw with 
Timber Chain and Anti-Mage with 
Blink.
Lina
* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, 
Enchantress, Queen of Pain
Tusk
* Queen Of Pain can similliar abilities from Anti-Mage 
Blink allows Queen of Pain to escape from an incoming Snowball and Ice Shards.
Lina
* Lina has a very long range of attack, which completely overlaps the range of Queen of Pain's abilities and attacks, which is why even a single 
Shadow Strike roll can become deplorable, since Lina will shoot Queen of Pain from a long distance before and after the Shadow Strike roll. And with the help of the abilities of Light Strike Array and Laguna Blade, Lina can even kill Queen of Pain because of her small health reserve if she is exposed to a blow

Lina
* 
Viper Strike prevents buildup of Fiery Soul stacks.
* 
Corrosive Skin provides magic resistance against Lina's spells. However, Lina can counter this with Silver Edge, a common item on Lina.
* 
Poison Attack and Viper Strike can burn away Lina's small health pool.
Tusk
* Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate. It's Viper Strike's break is also useless because he has no passive abilties at all. And to make things worse, Viper Strike cannot disable Walrus PUNCH! because it's an auto-cast ability
* As Tusk is a natural Silver Edge wielder, he can use it to disable Viper's magic resistance from Corrosive Skin, and make him vulnreable to his other allies.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Lina
* 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.
Lina
* Heroes with spell immunity unless Lina chooses to play Carry role like Lifestealer with Rage and Juggernaut with 
Blade Fury.
Tusk
* Heroes with abilities that can save teammates are also effective such as Shadow Demon, 
Dazzle, Oracle, Bane, Pugna, Tusk, 
Winter Wyvern, Io, Underlord, Treant Protector and Keeper of the Light.
Lina
*
Blink allows Anti-Mage to get on top of Lina and deal damage with his 
Mana Break.
Counterspell makes Anti-Mage tanky against Lina's heavy magic damage. It can also be used block and reflect Laguna Blade.
Mana Void is very hazardous for Lina, who has a high mana pool and quickly depletes it during fights.
*
*
Tusk
*
Mana Break is very effective against Tusk, as he has a very low mana pool.
Blink allows Anti-Mage to escape from an incoming Snowball.
Counterspell can reflect the Snowball back onto Tusk.
