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.
* A well-timed Counterspell can block and reflect Laguna Blade.
* 
Mana Void is very strong against Lina, who has a high mana pool and quickly depletes it during fights.
Leshrac
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and 
Leshrac.
Additional:
* Counterspell severely reduces Leshrac's magical damage.Counterspell also impacted reflect Lightning Storm and send back to Leshrac's also affected from movement speed.
* Leshrac already burns through his own mana with Pulse Nova, Mana Break will burn through even more.
* Leshrac's high mana pool will increase the amount of damage Mana Void does to him when his mana is low.
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.
Leshrac
* Leshrac needs to be close to target in order to do damage, Pugna can outrun Leshrac with ease due to his superior movement speed.
* 
Split Earth can also be hard to land on Pugna for the same reason.
* Leshrac uses huge amounts of mana to do damage, Nether Ward forces him to either not contribute in a fight or kill himself in the process.
Additional:
* 
Nether Ward punishes Leshrac's constant mana usage from spamming spells.
* Leshrac needs to be in the thick of the fight to deal damage, and so cannot escape from 
Nether Blast nor 
Life Drain easily.
Lina
* 
Mind Flare does tons of damage against Lina because of her high intelligence.
* The mana burn from 
Vendetta also prevents Lina from casting her full combo.
* 
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.
Leshrac
* Nyx Assassin's Spiked Carapace will stun Leshrac when hit by any of his AOE abilities.
* Mind Flare deals high damage due to Leshrac's high intelligence gain.
* Vendetta burns a large amount of Leshrac's essential mana pool.
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,

Blade Fury.
Leshrac
* Heroes with spell immunity: Juggernaut, 
Pangolier, Huskar.
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.
Leshrac
* Oracle's 
Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's 
False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* 
Fortune's End can stop Leshrac from chasing opponents or running away.
Lina
* 
Arcane Curse discourages Lina from using her abilities, preventing her from building up Fiery Soul stacks.
* 
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
* 
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
* 
Nethertoxin prevents buildup of Fiery Soul stacks.
* 
Corrosive Skin provides magic resistance against Lina's spells.
* 
Poison Attack and 
Viper Strike can burn away Lina's small health pool.
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.
Lina
* Puck dodges the abilities of Lina 
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 dodges the abilities of Lina 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
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
* 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
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them -

Leshrac
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, Jakiro, Leshrac, 
Naga Siren, 
Underlord.
Additional:
* Clockwerk naturally builds 
Blade Mail, reflecting Leshrac's high magic damage output back at him.
* 
Power Cogs will prevent Leshrac from reaching Clockwerk's team and dealing large AOE damage to them.
* Power Cogs will also keep Leshrac close, wasting his Diabolic Edict on just Clockwerk.
* 
Battery Assault interrupts Leshrac's long cast times of Split Earth and Lightning Storm.
Lina
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, 
Zeus.
Lina
* Heroes who cannot prevent Sven from killing supports will always be at a disadvantage in fights such as Lina, Slark and Zeus.
Additional:
* 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.
Leshrac
* Heroes with spell immunity: Juggernaut, Pangolier, Huskar.
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
* 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.
Leshrac
* Diabolic Edict and Pulse Nova will tear apart any illusions spawned from 
Disruption
* Split Earth can punish improper usage of Disruption.
* Leshrac does not have any buffs that can be removed by 
Demonic Purge.

Pulse Nova makes quick work of any illusions with amplified damage, and deals damage even if Leshrac is in Disruption.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Split Earth for the enemy.
* Disruption does not stop 
Diabolic Edict and Pulse Nova once they start pulsing, and even worse it provides a safe shelter for Leshrac to keep pumping up his powerful AoE damage onto the battlefield.
* Shadow Demon doesn't have the burst damage to take Leshrac out of the fight quickly, although Demonic Purge can help his allies kill a squishy Leshrac.
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

* Leshrac can catch multiple Meepos in Split Earth and follow up with the rest of his area damage spells making Meepo unable to get close to Leshrac.
* Diabolic Edict is a strong ability that can wear down a lone Meepo clone quickly.
Lina
* 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.
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.
Leshrac
* As Terrorblade's damage output comes mainly from direct attacks, he will struggle greatly against heroes who have abilities that give evasion, trigger on attack or which can disarm an enemy hero: Centaur Warrunner, 
Hoodwink, Huskar, Invoker, Leshrac with 
Nihilism from Aghanim's Scepter, Lifestealer with Aghanim's Scepter upgraded 
Infest, Pangolier, 
Phantom Assassin, 
Pugna, 
Techies, 
Windranger etc.
Lina
* 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.
Leshrac
* All of Leshrac's abilities, especially Pulse Nova, can easily deal with Naga Siren's illusions.
* Aghanim's Scepter gives Leshrac access to Nihilism ability, that allows him to turn himself along with Naga Siren and her illusions to turn ethereal. And to make things worse, Nihilism can slow Naga Siren and her illusions, make them more vulnerable to magical damage and unable to fight back while Leshrac moves faster and does not take increased magical damage for it's duration.
Lina
* Heroes with summons can find their summons eliminated easily by Lina, like Broodmother, 
Nature's Prophet, and 
Chen.
Additional:
* 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
* 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.
Leshrac
* Lightning Storm will usually hit both Io and his 
Tethered target since both will be close enough for the lightning to jump. It can then be followed up by Split Earth.
* Diabolic Edict and Pulse Nova hit all units near Leshrac, meaning he can do colossal damage to Io and his Tethered target.
Additional:
* Io is a hero who needs to be close to it's tethered target to make it effective, and that's where Leshrac gets the advantage thanks to many of his area-of-effect abilities.
* 
Lightning Storm will usually hit both Io and its tethered target since both will be close enough for the lightning to jump.

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.
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.
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.

Lina
* 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.
Additional:
* 
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.
Lina
* 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

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
* Laguna Blade ends Gyrocopter very quickly in the early to mid game.
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 
Heavenly Grace. 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.
Lina
* Laguna Blade can kill Dazzle quickly before he casts 
Shallow Grave.
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 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

Nature's Guise and 
Eyes in the Forest.

Living Armor's protection.
Leshrac
* Diabolic Edict and Pulse Nova hit all units around Leshrac, making it very easy for him to kill the 
Summon Familiars.
* Diabolic Edict and Pulse Nova also deal many instances of damage, nullifying 
Gravekeeper's Cloak.
* Split Earth and Lightning Storm makes it difficult for 
Visage to kite Leshrac, even while under the effects of 
Grave Chill.
Lina

Enchantress, 
Queen of Pain

Waveform and also prevents Morphling from using his abilities.
* Laguna Blade can kill Morphling quickly before he shifts into 
Attribute Shift (Strength Gain).
Leshrac
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like 
Mirana's 
Sacred Arrow or Leshrac's Split Earth, or combos like 
Kunkka's 
X Marks the Spot into 
Torrent.
Leshrac
* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos, 
Phoenix, 
Alchemist, Earthshaker, 
Razor, Tinker, Leshrac, Queen of Pain

Lina
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker, Jakiro, Lina, Luna, Pugna or

* Heroes who summon multiple units that are not spell immune. Nature's Prophet,Lycan,Beastmaster
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.
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
* 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.
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.

Diffusal Blade carrier.
Leshrac
* Leshrac's AoE abilities destroy Phantom Lancer's illusions.
