Malcolm, Keen-Eyed Navigator

Magmaw

Amorphous Axe

Exalted Sunborn

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 engine uses Magmaw to fuel a loop where sacrificing nonland permanents deals direct damage, turning each activation into a profit thanks to Malcolm, Keen-Eyed Navigator and Exalted Sunborn. When Magmaw deals damage to an opponent, Malcolm triggers to create a Treasure, but Exalted Sunborn doubles that generation into two Treasures instead of one. By sacrificing one Treasure to pay for Magmaw's ability and keeping the extra, you generate a surplus of mana and fodder to repeat the process until every opponent is reduced to zero. Meanwhile, Amorphous Axe sits on the battlefield ready to turn any creature into a Pirate, ensuring Malcolm's trigger condition is always met even if your primary attackers lack the creature type.
