Corrosive Skin minimizes the damage from Ignite and Fireblast.
Anti-Mage
[wiki] rating: 1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* 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.
Undying
[wiki] rating: 1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
Chaos Knight
[wiki] rating: 1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* 
Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.
Lifestealer
[wiki] rating: 1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's as hero with great durability and high health is great target for Lifestealer in any stage of the game, thanks to Feast.
Additional:

Rage and his high health pool amplifies 
Feast.

* 
Dark Pact dispels Ignite's slow and Fireblast's stun.
* 
Shadow Dance allows Slark to regenerate HP, even when he is affected by Ignite and Fireblast.
Winter Wyvern
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* 
Winter Wyvern's 
Winter's Curse works very well against the increased attack speed from Bloodlust.
Arc Warden
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* 
Arc Warden's 
Tempest Double is helpful for killing Ogre Magi who lacks AoE damage and disables.
Earth Spirit
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* 
Earth Spirit's useful kit of Slows, Stuns, and Silences can set up kills on Ogre Magi and the silence can stop him from using his abilities.
Legion Commander
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: 
Venomancer, Earth Spirit, 
Ogre Magi
Puck
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* 
Puck silences Ogre Magi with 
Waning Rift, and 
Phase Shift makes Puck untargetable for the duration.
Abaddon
[wiki] rating: 0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as 
Skywrath Mage, 
Techies, 
Juggernaut, 
Shadow Shaman, or Ogre Magi.
Sven
[wiki] rating: -1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Multicast Fireblasts over the course of fights are a decent nuisance to stall Sven's massive damage output.
* Bloodlust and Ignite gives Ogre Magi's team the movement speed difference needed to chase and/or disengage against a Sven and his 
Warcry.
* Ignite provides strong damage over time to pressure Sven early on in the laning phase and keep his health low, delaying his transition into the jungle. Ignite is also an easy way to disrupt 
Blink Dagger, Sven's most popular way of initiation.
* Ogre Magi's presence in the laning phase both in terms of damage and durability keeps high pressure on Sven in lane.
* Purchasing an 
Aghanim's Shard allows Ogre Magi to greatly reduce the burst damage of Sven, who tends to build items focused on damage per hit instead of attack speed.
Nature's Prophet
[wiki] rating: -1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Nature's Prophet treants can be cleared by Ignite or Multicast 
Hand of Midas
* Fireblast and Unrefined Fireblast prevents Nature's Prophet from using 
Teleportation.
Templar Assassin
[wiki] rating: -1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* The damage block instances of 
Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a 
Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.
Earthshaker
[wiki] rating: -1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Ignite can prevent Earthshaker from escaping and/or initiating with Blink Dagger.
* Fireblast and Unrefined Fireblast may help prevent Earthshaker follow through with his combo after landing an 
Echo Slam.
Io
[wiki] rating: -1.0 (winrate: 0% pickrate: 0%)Ogre Magi
* Fireblast is a good tool to interrupt Io during its escapes through 
Tether.
* Ignite can be one of the few spells with enough total damage to out-trade the sustained healing Io provides for its fellow laner.
* However, picking other supports that focus less on the laning phase is generally a better choice against Io.
Mars
[wiki] rating: -1.0 (winrate: 48% pickrate: 24%)Ogre Magi
* Mars has no way to trade with Ogre Magi in the early game thanks to his high base health, resistance and Ignite.
* Once Ogre Magi gets level 2 he may also have 
Bloodlust, which makes him even harder to deal with in lane.
* 
Fireblast can be ridiculously strong later on in the game for controlling Mars.
* Spear of Mars, which is Mars' main source of damage in the early game, cannot guarantee kills early on Ogre Magi.
Weaver
[wiki] rating: -1.0 (winrate: 59% pickrate: 22%)Ogre Magi
* A well-timed Fireblast with Multicast can prevent Weaver from escaping with 
Shukuchi and even 
Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and Time Lapse dispels it if needed.
Techies
[wiki] rating: -0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* Techies struggles early game against heroes with naturally large strength and health regeneration such as 
Pudge, 
Axe or Ogre Magi, as the player is forced to lay down more mines than usual to kill these bulkier heroes.
Void Spirit
[wiki] rating: -0.6 (winrate: 0% pickrate: 0%)Ogre Magi
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: 
Sven, 
Tiny, 
Wraith King, Ogre Magi.
Spirit Breaker
[wiki] rating: -0.6 (winrate: 58% pickrate: 22%)Ogre Magi
* Heroes that can cancel Charge of Darkness: Ogre Magi, 
Earthshaker, Lion .
Ogre Magi
* Ogre Magi has single-targeted magical-only damage and disables and is less effective against Meepo's clones.
