* Luna has low HP, low range and often stalks through jungle. She cannot properly disarm Proximity Mines and could fall victim to their traps.
* Of course, if Luna happens to catch Techies off-guard, they won't be able to survive for long against Eclipse, Lucent Beam, and right-clicks.

* Lina has very high magic burst damage to use against the low-health-pool Luna. Laguna Blade can also be upgraded with Aghanim's Scepter to bypass Luna's Black King Bar, making Lina even more of a threat.

* 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.

* Stasis Trap can lock multiple Meepos in place and prevent them from Poofing.
* Proximity Mines, Remote Mines and Blast Off! can deal heavy magic damage to multiple Meepos.

* 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.

* 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.
Additional:
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* 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.

* 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.

* Heroes with high damage output who can burst down Morphling before he has time to use Attribute Shift (Strength Gain), like Lina and Lion.

Additional:
* 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).

* Abilities that can destroy trees can give Hoodwink a disadvantage: Timbersaw, Windranger, Lina.

* 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.

* Heroes with low health or rely on evasion can easily be bursted down, like Phantom Assassin or Terrorblade.

Additional:
* Laguna Blade is one of the best tools to kill Terrorblade before he can use Sunder due to its high magical (pure with Aghanim's Scepter) burst damage.
* Dragon Slave and Light Strike Array allows Lina to clear Terrorblade's illusions from both, Conjure Image and Manta Style.

* 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! silences Terrorblade, preventing him from casting Sunder.

* 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.
Additional:
* Proximity Mines and Stasis Traps 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.

* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.

* Laguna Blade ends Gyrocopter very quickly in the early to mid game.

* 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.

* 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.

* 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.

* 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 will be greatly amplified during Ghost Shroud.

* 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.

* 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.

* Laguna Blade can kill Dazzle quickly before he casts Shallow Grave.

* 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.

* 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.
* 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 buys Aghanim's Scepter, that will change Laguna Blade's damage type from magical to pure and allow it to ignore both, any form of spell immunity and Guardian Angel.

* 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.

* Heroes who deal single instance burst damage will only proc Bristleback once: Lina, Lion.

* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina

* In general, heroes that provide vision will see Dark Rift coming: Techies, Templar Assassin, Treant Protector

* Heroes with high burst damage: Lina, Lion, Luna, Nyx Assassin, Queen of Pain.

* 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.

* 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 has both a silence and a powerful nuke in Blast Off!, root from Stasis Trap and even more magical damage in Proximity Mines and Remote Mines.

* 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.

* Heroes whose abilities can affect multiple enemies at once: Lina, Luna, Jakiro, Leshrac, Invoker, Lina

* 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.

* Heroes who have channeled abilities can be stunned by Light Strike Array, like Witch Doctor with Death Ward and Bane's Fiend's Grip.

* Heavy nukers will do well against Cold Embrace (Lina, Zeus etc).

* 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.

* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage

* 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.

* 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.

* Stasis Trap's root prevents Earth Spirit from using Rolling Boulder to escape.

* 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.

* Heroes with summons can find their summons eliminated easily by Lina, like Broodmother, Nature's Prophet, and Chen.

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.

* Heroes with damage burst can often kill Chen or his allies before he can use Hand of God: Lina, Techies, Shadow Fiend, Pugna, Nyx Assassin.

* 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.

* Timbersaw has a difficult time against magical and pure damage: Lina, Leshrac, Enchantress, Queen of Pain

* Heroes with low health or rely on evasion can easily be bursted down, like Phantom Assassin or Terrorblade.

Additional:
* Light Strike Array catches Phantom Assassin when she jumps in.
* Laguna Blade kills Phantom Assassin's abysmal health before she can do anything in early to mid game and also pierces her spell immunity when upgraded with Aghanim's Scepter.

* 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.

* 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.
* Lina usually builds Eul's Scepter of Divinity to dispel Soul Catcher and Linken's Sphere to block Disruption and Demonic Purge.
* 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.

* Eul's Scepter of Divinity and Light Strike Array combo will disable Mirana if she tries to Leap away.
* Laguna Blade's magical (pure with Aghanim's Scepter) 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.

* 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.

* 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.

* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Puck, Slark, Nyx Assassin, etc.
