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.
Techies
* Thanks to Counterspell's magic resistance, Anti-Mage has a good chance of surviving a Blast Off combo.
* Anti-Mage is a natural 
Manta Style carrier, meaning he can dispel the silence from Blast Off and blink away when Techies initiates on him.
Lina
* 
Doppelganger can be used to easily dodge Light Strike Array if timed correctly.
* 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.
Techies
* Illusions can be sent out to destroy 
Techies mines.
Lina
* Heroes with low mobility that rely on spells: 
Zeus, 
Lina, 
Crystal Maiden.
Techies
* 
Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* 
Crippling Fear is effective in stopping Techies from using Blast Off and 
Void is effective in stopping them from running to the safety of their mines.
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 (except an upgraded Laguna Blade).
* 
Open Wounds is great to keep Lina in place because she has no abilities to help her escape.
Techies
* Rage protects Lifestealer from all of Techies' abilities. 
Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies' 
Proximity Mines safely.
Additional:
* Lifestealer's Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.
Lina
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: 
Lich, Lina, 
Sniper, 
Outworld Destroyer Zeus
Techies
* 
Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Lina
* Heroes with spell immunity until Lina takes Laguna Blade damage is pure and pierces spell immunity talent, like 
Lifestealer with Rage and 
Juggernaut with 
Blade Fury.
Techies
* Juggernaut can trigger Proximity Mines while in Blade Fury, and can walk away from a initiation with Blast Off if Blade Fury is activated before the silence.
* Juggernaut ignores Reactive Tazer when he uses 
Omnislash, whether Techies used it to protect an ally or themselves.
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.
Techies
* As long as Batrider is under the effect of Firefly, he can safely fly over Proximity Mines (He does not receive vision over the mines).
Techies
* Oracle can negate all of Techies' skills with Fate's Edict, as they are all magic damage. Fate's Edict can also be used to search and trigger Proximity Mines when crossing mined territory.
* Oracle can dispel Reactive Tazer off Techies, as well as the silence from 
Blast Off!, with Fortune's End.
* Oracle can further delay Techies' burst damage capability with False Promise.
Additional:
* 
Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage.
* Oracle's 
Fortune's End dispels Reactive Tazer buff from Techies allowing him to be attacked. However, Reactive Tazer will instantly perform the area of effect disarm that is normally applied at the end of the duration.
* Fortune's End will also dispel Blast Off silence, Techies' Etheral Blade, Proximity Mines' magic resistance reduction, and Sticky Bomb's slow. However beware that it will only dispel Sticky Bomb's first or second instance of slow and not the damage, which will trigger as normal.
Techies
* Familiars can fly over the mines, rendering them safe from damage of Techies's mines. Visage can also use Familiars to check for mines on the map.
* Techies's low attack speed and damage will give them a hard time in destroying Visage's Familiars, and that can become even worse if they are affected by 
Grave Chill.
* 
Gravekeeper's Cloak allows Visage to survive Damage from Techies's mines.
Techies
* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.
Techies
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.
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.
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
* 
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
* 
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
* 
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
* Heroes with long animations can be frequently interrupted with Cold Snap: 
Earthshaker, 
Monkey King, 
Shadow Fiend Lina
Techies
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, 
Enchantress, 
Gyrocopter, Lion, 
Riki, Techies, 
Terrorblade, 
Necrophos, 
Invoker.
Techies
* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, Pudge, Techies.
Lina
* Both Lion's 
Finger of Death and Lina's Laguna Blade have a 0.25 second delay before the damage is dealt.
Techies
* Aphotic Shield makes it less likely for allies to be killed by mines.
* Because they explode in very short intervals, a stack of 
Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of 
Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.
Additional:
* 
Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* 
Aphotic Shield's can easily break Techies' Etheral Blade combo.
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.
Techies
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, Techies, 
Rubick
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.
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
* Squishy heroes (
Io, Crystal Maiden, Lina...), as Earth Spirit can deal tons of damage with Magnetize.
Lina
* Low health spellcasters: Lina, 
Witch Doctor, 
Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Techies
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, 
Magnus, 
Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
Lina
* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.
Techies
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
Techies
* 
Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.
* Death Prophet is a natural Eul's Scepter of Divinity carrier, meaning she can easily escape a Blast Off initiation.
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
* 
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.
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
* 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).
Techies
* Morphling usually has low max health due to shifting strength into agility, which combined with Blast Off's silence will prevent him from using Waveform and 
Adaptive Strike (Strength), leaving him defenseless and making him an easy target to burst down.
Lina
* Light Strike Array catches Meepo and his clones if he tried to gank Lina with 
Earthbind & 
Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
Techies
* Reactive Tazer can lock multiple Meepos in place and prevent them from Poofing.
* Proximity Mines, 
Sticky Bomb and Blast Off! can deal heavy magic damage to multiple Meepos.
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.
Techies
* Techies can easily catch Chen off guard and kill him quickly with Blast Off! and 
Ethereal Blade combo, especially because Blast Off! can silence Chen and stun him when upgraded with 
Aghanim's Shard.
* However, Chen's converted creeps can trigger Proximity Mines, wasting them.
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' weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Techies
* Heroes with nukes that can jump her: 
Clockwerk, 
Snapfire, 
Spirit Breaker, Techies
Additional:
* Techies does huge amounts of magical damage, which will bypass Untouchable.
* Enchantress depends on abilities to do damage and heal, which Blast Off's silence prevents.
Lina
* Abilities that can destroy trees can give Hoodwink a disadvantage: 
Timbersaw, 
Windranger, Lina.
Techies
* Remote Mines are frequently placed in trees, and can thus kill an unwary Hoodwink should she 
Scurry away due to her low HP pool.
* Blast Off! can clear out trees, denying the tactical advantages from Scurry.
Techies
* 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.
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.
Techies
* Techies deals lots of magical damage with Sticky Bomb, Blast Off! and Proximity Mines that bypasses Terrorblade's high armor and can punish his low max life.
* Sticky Bomb is easy to land on a large clump of Terrorblade illusions and will damage and slow Terrorblade and all of his illusions if he can't quickly move the right one away.
* Reactive Tazer upgraded with Aghanim's Scepter can be used to protect an ally getting attacked by Terrorblade. Further, it disarms all of his illusions even while he has activated Black King Bar, greatly decreasing his damage.
* Blast Off! stuns Terrorblade, preventing him from casting Sunder.
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.
Techies
* Proximity Mines can be placed near trees to detect Monkey King.
* Follow up with Blast Off! to destroy the tree, causing Monkey King to take high damage, fall from the tree, and become stunned.
Additional:
* Techies can turn his tree jumping ability against him, by placing Proximity Mines that will detect him near trees, and then destroying the trees around him with Blast Off, stunning him and dealing high damage, on top of him being silenced when the stun expires.
* Monkey King's mobility is also severely limited around Techies' mines as he will almost always trigger them due to the cooldown time between tree jumps. Monkey King will be forced to take mine damage or escape with 
Primal Spring.
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.
Techies
* If Storm Spirit isn't careful, he could fall into a trap set by Techies and another hero acting as bait.
* Stasis Trap roots Storm Spirit for 2/3/4/5 seconds and Blast Off! silences for 4/5/6/7 seconds, which effectively prevents Storm Spirit from using 
Ball Lightning to escape for a lengthy duration.
Techies
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.
Lina
* Laguna Blade ends Gyrocopter very quickly in the early to mid game.
Lina
* Laguna Blade deals amplified magical damage (pure from Aghanim's Scepter) to Necrophos when he is under the effects of 
Ghost Shroud.
Additional:
* Laguna Blade's damage as well as damage from all of Lina's abilities will be greatly amplified during Ghost Shroud.
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
* 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
* 
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.
Techies
* Techies has great area of effect damage to deal with 
Phantasm illusions.
* Blast Off silences Chaos Knight, stopping him from using his disables and allowing his teammates to walk away from his heavy damage.
* Reactive Tazer will disarm all of Chaos Knight's illusions even if he has activated his Black King Bar.
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 remove 
Living Armor's protection.
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 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 high burst damage: Lina, Lion, 
Luna, 
Nyx Assassin, 
Queen of Pain.
Lina
* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).
Techies
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, 
Templar Assassin, 
Treant Protector
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 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.
Techies
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, Riki, 
Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
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.
Techies
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
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.
Techies
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Techies
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
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.
Lina
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Techies
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
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
* 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
* 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.
Additional:
* 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.

Techies
* 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.
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
* 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.
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.
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.
Techies
* Some abilities deals damage from an independent source and not from the hero itself, so Nyx cannot counter them with Spiked Carapace: illusions or summoning units, 
Homing Missile, 
Nimbus, 
Mass Serpent Ward, Death Ward and especially Techies's mines.
Lina
* Heroes that can close the gap can easily chase her 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
Techies
* 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.
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.
Techies
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
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.
Techies
* Techies spends lots of time standing still planting stacks of 
Land Mines away from creep waves.
* Sacred Arrow can be used to scout hidden Land Mines among trees and at uphill places. It can also be used to catch Techies while he's planting them.
* If Techies is hit with a Sacred Arrow, he can be killed before he has a chance to use Blast Off!.
* Mirana has a high attack range to destroy his traps from a safe distance.
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.
Techies
* Shadow Demon's spammable illusions can be used to scout Techies' Proximity Mines. The illusion of your carries can be even used to trick Techies into detonating his precious Remote Mines.
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.
Techies
* Plague Wards may reveal a hiding Techies. If there's a sentry nearby, they may also reveal a stack of mines hidden in a juking spot.
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.
Techies
* 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.
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.
Techies
* 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.
Lina
* Heroes with summons can find their summons eliminated easily by Lina, like Broodmother, Nature's Prophet, and 
Chen.
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
*
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.
*
*
Techies
*
Corrosive Skin will protect Viper from Techies' magical damage.
Poison Attack, he does lots of damage with his other abilities that can still kill Techies.
* Even though Reactive Tazer will disarm Viper if he attacks Techies with
