Bfury-less Anti-Mage

Anti-Mage doesn't have the stats to survive early game, if one person on the enemy team is wise enough to focus you, you're dead. He needs at least the Manta Style to fight.

It's a legit way to play him, especially if the enemies are reliant on nuking INT heroes. It's how I used to play him back in Dota 1, and honestly, if you're in a game with heroes that'll try to steal your farm anyway (between the jungle LCs, Medusas, Alchemists, Juggernauts, and Terrorblades), it's probably your best chance to win by activating early (btw, according to Dotamax Jugger and TB on same team as AM is some of his worst allies for his winrate). You can even get a battlefury later for the splitpushing, but an earlier manta is very powerful on AM and his big power spike can come earlier.

But you gotta beware of counterpicks really badly if you run this. Heroes with AOE stuns (Slardar, Axe, anyone who makes your manta spike timing rather useless), with non-magical burst damage (QoP, Timber), or with a ton of disables {Lion, Doom), you probably don't want to do this, since you won't have a recovery option and its pretty hard to snowball against it. And also avoid it against tanky heroes whose mana you will burn out but you won't be able to kill with Void.
