* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, after an Incapacitating Bite she will get her swarmed in no time.
* Medusa usual do not build a BKB to benefit from Mana Shield fully while Broodmother can fit a Diffusal Blade to burn away mana.
Additional:
* Incapacitating Bite will give Medusa a dire time to clear horde of small spiderlings or retaliate Broodmother herself.
* Spin Web will allow broodmother to pick her own fights and sometimes slip away to ambush Medusa.

* Anti-Mage easily destroys Mana Shield with Mana Break, especially once he has Manta Style.
* Anti-Mage effectively avoids Stone Gaze with Blink, and can reinitiate after its duration is over.
Additional:
* Anti-Mage's Mana Break burns Medusa's mana easily, especially when coupled with a Manta Style.
* Can easily initiate on Medusa with Blink, burning her mana or forcing her to use Stone Gaze.
* Mana Void is effective against Medusa's big mana pool and mana usage, presenting a huge hazard to Medusa's allies around her since her Mana Shield still gives her some protection if she has mana.

* Spin Web and Broodmother's auto-attacks allow her to gank Rubick easily before Rubick has a chance to retaliate, especially if Broodmother obtains Orchid Malevolence.
* Broodmother loves buying Diffusal Blade, which drains Rubick's low supply of mana, preventing Rubick from spamming his abilities.
* Though Insatiable Hunger is a great spell to steal, Broodmother's untargetable nature and her low cooldown spells makes it a difficult spell to steal.

* Mana Break quickly eats away at Rubick's low mana pool, preventing Spell Steal abilities from triggering.
* Rubick's complete lack of mobility makes him very easy for Anti-Mage to chase down with Blink.
* Anti-Mage dispels Fade Bolt damage reduction debuff with Manta Style or severly reduced by Counterspell.

* Anti-Mage's mobility and magic resistance make him nearly impossible to kill alone.
* Invoker's spells cost a lot of mana, and Invoker himself has a lot of mana. This means Invoker and his team are vulnerable to Mana Void's heavy damage.
* Blink allows Anti-Mage to escape from Invoker's combo if he doesn't have disables.

* Broodmother can kill Invoker easily in the early game with her Spawn Spiderlings and her spiderlings.
* Broodmother is both an Orchid Malevolence and a Nullifier carrier. As she can farm it early, she can kill Invoker easily.

* Mana Break quickly eats away at Wraith King's small mana pool, preventing Reincarnation from triggering.
* Wraith King has no innate mobility. Even with Blink Dagger, Wraith King is easily kited by Blink.
* Anti-Mage can farm much more quickly than Wraith King, allowing Anti-Mage to overpower Wraith King once a significant farm advantage is established.
Additional:
* Mana Break can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard that removes the mana cost from Reincarnation.
* With Manta Style, his mana burning will triple because illusions can also use Mana Break.

* Broodmother can easily clear Wraith King's skeletons with Spawn Spiderlings and summon spiderlings in their place.
* With Diffusal Blade, Broodmother can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard.

* Anti-Mage Blinks directly into Magnetic Field, bypassing its protection.
* Anti-Mage's high mobility allows him to deal with Tempest Double while it is split-pushing.
* Anti-Mage's Battle Fury cleans up Arc Warden's Necronomicon summons, and Counterspell protects him from Necronomicon Warrior's Last Will.
Additional:
* Arc Warden's high reliance on casting spells leads him to be dependent on mana, which Anti-Mage can easily burn with Mana Break. Coupled with the fact, that Magnetic Field doesn't work against melee gap-closing heroes and Zet's low armor, Anti-Mage will almost always be able to kill Arc Warden in one-on-one situation.
* Blink mitigates the threat of Flux slow and allows Anti-Mage to close the distance between himself and Arc Warden.
* Anti-Mage's ability to farm quickly allows him keep up with Arc Warden's farm while also de-pushing the lanes Arc Warden shoves in with Tempest Double. When Tempest Double clone meets Anti-Mage, the former will be killed very quickly, giving Anti-Mage even more farm.
* Counterspell significantly reduces the effectiveness of Arc Warden's magic damage.

* None of Arc Warden's skills work against Broodmother and her Spiderlings.
* Arc Warden is forced to go any lane other than mid, which he doesn't want to do, because on the lane against Broodmother he'll die over and over again.
* Broodmother is a hero best known for ending the game very early, and Arc Warden needs a couple of items to be effective.
* Arc Warden has no disables to stop Broodmother from lifestealing with Insatiable Hunger and shredding through Zet's low armor.

* Enchantress is well known for taking control of various summons with her Enchant. However, Broodmother's summons are not a good target for that, because she can swarm up a bunch of her summons with Spawn Spiderlings and Enchantress has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
Additional:
* Enchantress' lack of AoE abilities allows Broodmother to swarm her with Spiderlings.
* Spawn Spiderlings can kill enchanted creeps.

* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage

* Anti-Mage's high mobility from Blink and tendency to build Battle Fury makes him strong against split-pushing heroes: Nature's Prophet, Tinker, and Arc Warden.

* Broodmother can destroy Nature's Prophet's treants with Spawn Spiderlings and summon spiderlings in their place.
* Broodmother loves buying Orchid Malevolence, which can prevent Nature's Prophet from escaping with Sprout and Teleportation.
Additional:
* Sprout cannot protect Nature's Prophet if Broodmother puts down a web.
* Nature's Prophet's low mobility means he is defenseless against Incapacitating Bite.
* Spiderlings absorb much of the damage from Wrath of Nature.

* Sniper is completely helpless against Incapacitating Bite, and can be seriously damaged by Spiderlings in lane.

* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.

* Heroes with summons like Broodmother,Enigma, Invoker, Nature's Prophet, Lycan, Visage;or illusions, like Naga Siren, Phantom Lancer, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity mines in the early game.

* Thanks to Counterspell Anti-Mage can fight Techies head on and trip multiple mines once the late game hits.

* Chain Frost can bounce to the Spiderlings that Broodmother spawns.

* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.

Additional:
* Although he can be effective against Anti-Mage in an aggro offlane, Lich has a hard time nuking down Anti-Mage in the midgame due to his Counterspell.
* All of Lich's abilities are also targeted, which makes it much harder to disable Anti-Mage.
* In the lategame, Anti-Mage can easily pick off Lich with Blink, and the high mana cost of Chain Frost along with Lich's large mana pool makes him vulnerable to Mana Void.
* Blink allows Anti-Mage to escape Chain Frost.

* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or Broodmother.

* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: Lich, Necrophos, Oracle, and Leshrac.

Additional:
* Oracle has minimal damage potential against Anti-Mage due to Counterspell, and may even have some ability damage reflected at himself.
* Anti-Mage can easily overwhelm Oracle with Mana Break and Mana Void.
* Blink allows Anti-Mage to easily chase and take advantage of Oracle's low mobility.

* Counterspell's bonus magic resistance causes the Ethereal Blade and Adaptive Strike combo to deal significantly less damage.
* Counterspell's active component can reflect the Ethereal Blast and Adaptive Strike combo back into Morphling, dealing significant damage or even killing him.
* Mana Break combined with Manta Style can quickly burn away Morphling's mana, leaving him unable to use his spells.

* If Meat Hook is used before Blink, Anti-Mage may be able to escape Pudge's grasp by blinking safety.
* Counterspell grants Anti-Mage a large degree of magic resistance, a damage type Pudge is highly reliant on to secure kills. This make Anti-Mage a bad target for Pudge. The active can also block Dismember if timed correctly.
* Mana Break can quickly drains Pudge's low supply of mana, which may render Meat Hook & Dismember unusable and making him a prime target for Mana Void.

* Chen has no area-of-effect spells to deal with Broodmother's spiderlings and must rely on his creeps to take care of them.
* Spawn Spiderlings can kill Chen's creeps and spawn spiderlings in their place.
* Spin Web allows Broodmother to disrupt Chen's jungling.
* Incapacitating Bite and Insatiable Hunger let Broodmother easily win fights against Chen.
Additional:
* Chen's low mobility and lack of AoE abilities makes him an easy target for Broodmother and her Spiderlings.
* Broodmother can easily pick off Chen's creeps with Spawn Spiderlings, and by ambushing them through terrain in her web.

* Spectre cannot chase down Anti-Mage with Spectral Dagger because of Blink, though it still grants her team vision over him.
* Counterspell reduces much of the damage from Dispersion and Spectre's Radiance.
* Anti-Mage usually builds a Manta Style, preventing Spectre from dealing any Desolate damage to him once he summons his illusions.
Additional:
* Spectre has no way to prevent Blink, for escape or initiation. Anti-Mage can easily pick off enemy supports and Spectre cannot do anything about it.
* Mana Break burns through Spectre's low mana pool.
* Manta Style's illusions prevent Desolate's damage.
* Even though Anti-Mage is outcarried by Spectre in the later stages of the game, a competent Anti-Mage with a Battle Fury can easily outfarm and get ahead of Spectre before she can come online.

* Mana Break makes Gyrocopter, who has low mana pool, unable to use his abilities that most of his damage output depends on.
* Counterspell negates magical damages from Gyrocopter and it can also reflect Homing Missile back to himself.
* Anti-Mage can easily escape from Gyrocopter's attack range and Call Down with Blink.

* Past the mid game, an isolated Vengeful Spirit makes for an easy kill for Anti-Mage.
* Magic Missile is the only disable Vengeful Spirit has against Anti-Mage, but he can either Blink away to disjoint the stun or reflect it back against Vengeful Spirit with Counterspell.
* Nether Swap isn't very effective against Anti-Mage - if used offensively, Anti-Mage can simply blink away to safety, and if used defensively, Blink's low cooldown allows him to persistently chase as well.

* Because Queen of Pain's spells cost a decent amount of mana, Anti-Mage can easily use Mana Void if she spams her spells recklessly.
* Anti-Mage has similar mobility through Blink, which can allow him to catch up with her.
* Counterspell will reduce the damage done by Shadow Strike and Scream of Pain.

* Zeus almost exclusively relies on magical damage, which is heavily reduced by Counterspell.
* Zeus' complete lack of mobility makes him very easy for Anti-Mage to chase down with Blink.
* Zeus likes to stand in the back during team fights, but Anti-Mage can easily Blink to close the distance.
Additional:
* Anti-Mage can burn mana, which is a big problem for a spellcaster like Zeus that heavily relies on it.
* Counterspell decreases magical damage taken from Zeus.
* Zeus' high intelligence and mana pool makes him a perfect target for Mana Void.

* 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 reflects the Snowball back onto Tusk

* Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.

* Her Spiderlings can harass Luna in lane heavily, as Luna has no AoE abilities to clear Spiderlings.
* Broodmother can knock down towers in the early game quickly, and limit Luna's farming space.

* Anti-Mage dispels Phoenix's slows with Manta Style.
* Anti-Mage can Blink directly next to Supernova, giving him more time to destroy the egg.

* Venomancer's damage-over-time abilities do little damage against Counterspell.
* Blink helps Anti-Mage get away from Venomancer's slows.
Additional:
* Counterspell provides magic resistance, diminishing the effectiveness of Venomancer's spells.
* Venomancer's lack of hard disable allows Anti-Mage to use Blink, circumventing the slows Venomancer depends on.

* Ogre Magi only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage dispels Ignite with Manta Style.
* Ogre Magi has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.

* Anti-Mage can Blink into or out of Power Cogs, negating Clockwerk's initiation and bypassing his defenses.
Additional:
* Anti-Mage can easily Blink out of Power Cogs, escaping any ganking or initiation attempts.
* Mana Break depletes Clockwerk's much-needed mana.

* Counterspell negates Dark Willow's high magic burst damage. Its active blocks Cursed Crown.

* Pugna has a very large mana pool. This allows Anti-Mage to constantly deal bonus damage to Pugna with Mana Break and devastate Pugna's entire team with Mana Void.
Additional:
* Since Pugna relies on his teammates for protection, it is fairly common for Anti-Mage to get multiple kills with a single use of his Mana Void on Pugna if he's missing a considerable portion of his mana.
* Pugna's massive mana pool will result in Anti-Mage's Mana Break almost always dealing the bonus damage from the mana burn.
* Counterspell negates a large amount of Pugna's damage, as most of Pugna's damage comes from his spells.

* Counterspell decreases the amount of damage received from Aphotic Shield and Mist Coil.

* Enigma's Midnight Pulse damage can be substantially mitigated by Anti-Mage's high magic resistance thanks to Counterspell.
* In the early game, Anti-Mage's Mana Void can cancel a Black Hole until Enigma gets his Black King Bar.
* Should Anti-Mage survive a Black Hole combo, Enigma will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.

* However, Anti-Mage is weak early-game to Ancient Seal until he can dispel silences, but still, Skywrath's solo kill potential is very low.

* Death Prophet has a high mana pool and due to her heavy reliance on her spells, she will be a prime target for Mana Void.
* Death Prophet has less mobility than Anti-Mage due to Blink.

* Drow Ranger's lack of mobility makes her easy prey for Broodmother and her Spiderlings.
