* 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.

* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.

* Mana Shield tanks most of the damage from Reaper's Scythe; with sufficient mana, the kill threshold drops significantly.
* Necrophos has a movement speed equal to Medusa, and is easy to chase down with a slowing item in Medusa's inventory.

* 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.

* Poof won't damage Medusa and she can Gaze an entire flock of Meepos.
* Mystic Snake will easily become the bane of Meepo early game.

* 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.

* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Keeper of the Light, Puck.

* Medusa's Split Shot can make quick work of Enigma's Eidolons and take advantage of their considerable bounty.
* If Medusa activates Stone Gaze at the start of a fight, it can make initiating — and landing an effective Black Hole exceedingly difficult.
* Stone Gaze can cancel Enigma's Black Hole even through spell immunity, which can discourage Enigma from initiating with Black Hole.
Additional:
* Mana Shield makes Medusa harder to kill with Enigma's Black Hole and Pulse combo.
* Medusa's Split Shot can kill Demonic Conversion creeps easier and Mystic Snake bounces off from them.
* Stone Gaze makes it hard for Enigma to approach Medusa for a Black Hole.

* 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 cleave abilities and area of effect damage can make quick work of Chen's converted creeps and at same time gain farm: Magnus, Jakiro, Shadow Fiend, Kunkka, Luna, Dragon Knight, Medusa, Alchemist.

* 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.

* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.

* Split Shot will keep attacking Pangolier even when he is rolling around.
* Stone Gaze stuns Pangolier during Rolling Thunder, or forces him to roll away.

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

* Mana Shield makes it very difficult for Bloodseeker to gain his Thirst bonuses.
* Rupture rarely kills Medusa through Mana Shield.

* If Medusa activates Stone Gaze, the charge will inevitably fail.
* Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation.

* 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 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.

* 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.

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

* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.

* 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.

* 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.

* 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.

* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.

* Her Mana Shield is too tough for Lycan to break.
* Mystic Snake can hit for a massive damage once it spread between his summons.
Additional:
* Can be easily petrified despite his speed.
* Summoned wolves will be targeted by Split Shot or Mystic Snake

* 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 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.

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

* Heroes with disables that ignore spell immunity will render Phantom Assassin quite useless in teamfights throughout the game: Axe, Enigma, Vengeful Spirit, Doom, Bane, Beastmaster, Pudge, Medusa.

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

* 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).

* Medusa's Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.

* 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.

* 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.

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

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

* 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.

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

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

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

* Heroes with a lot of burst damage, especially those who rely on casting spells: Lina, Zeus.

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

* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter, Kunkka, Magnus and Medusa.

Additional:
* Summoned gargoyles are easy targets to Split Shot.
* Mana Shield will resist Soul Assumption instances without effort.

* 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 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 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.

* Medusa's Split Shot will whittle down all of Naga Siren's illusions, including Naga Siren herself.

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

* 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:
* 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.

* Mana Shield reduces the effectiveness of Counter Helix.
* Stone Gaze makes it very difficult for Axe to pursue.

* Stone Gaze allows Medusa to easily kite and kill Sven.
* Mana Shield negates much of Sven's burst damage.

* Lifestealer's low mobility makes him easy to kite.
* Stone Gaze pierces Rage, wasting its cooldown and making Lifestealer unable to fight.

* Medusa cares less than other heroes about armor reduction, since Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
