Malcolm, Keen-Eyed Navigator + Magmaw + Unnatural Selection + Parallel Lives

Malcolm, Keen-Eyed Navigator

Magmaw

Unnatural Selection

Parallel Lives

How it works

1. Activate Unnatural Selection by paying 1, causing Magmaw to become a Pirate until end of turn.
2. Activate Magmaw by paying 1 and sacrificing another nonland permanent, dealing 1 damage to an opponent.
3. Malcolm triggers, creating two Treasure tokens.
4. Activate a Treasure by tapping and sacrificing it, adding 1.
5. Repeat from step 2.

This clever loop turns your own board state into an endless artillery barrage by turning Magmaw into a Pirate with Unnatural Selection. With Malcolm, Keen-Eyed Navigator watching from the command zone, every single activation of Magmaw deals damage that triggers the creation of Treasure tokens, a yield instantly doubled by Parallel Lives. Sacrificing those very Treasures (or other expendable permanents) to feed Magmaw provides both the necessary mana and the fuel to keep the cycle spinning infinitely until every opponent is reduced to zero life.
