Malcolm, Keen-Eyed Navigator + Magmaw + Amorphous Axe + Anointed Procession

Malcolm, Keen-Eyed Navigator

Magmaw

Amorphous Axe

Anointed Procession

How it works

1. Activate Magmaw by paying 1 and sacrificing another nonland permanent, dealing 1 damage to an opponent.
2. Malcolm triggers, creating two Treasure tokens.
3. Activate a Treasure by tapping and sacrificing it, adding 1.
4. Repeat.

This loop turns Malcolm, Keen-Eyed Navigator and Magmaw into a lethal firing squad by leveraging Amorphous Axe to make Magmaw a Pirate so its damage counts as Pirate damage. Every time Magmaw flings a permanent at an opponent, Malcolm triggers to generate a Treasure token, which is instantly doubled into two tokens thanks to Anointed Procession. Sacrificing one of those newly minted Treasures to fuel Magmaw leaves you with an extra token to spare, creating a self-sustaining loop that easily generates infinite damage to close out the game.
