Malcolm, Keen-Eyed Navigator + Magmaw + Leyline of Transformation + Exalted Sunborn

Malcolm, Keen-Eyed Navigator

Magmaw

Leyline of Transformation

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.

With Leyline of Transformation reshaping the battlefield to turn every creature into a Pirate, Magmaw and Malcolm, Keen-Eyed Navigator form a self-sustaining engine of destruction. Magmaw provides the sacrificial outlet to ping your opponents, which immediately triggers Malcolm to generate Treasure tokens—a payout that is doubled thanks to Exalted Sunborn's token-doubling replacement effect. You then sacrifice one of those Treasures for mana to fund Magmaw's activation, leaving a surplus of extra tokens to fuel the loop into infinite damage.
