Malcolm, Keen-Eyed Navigator + Magmaw + Amorphous Axe + Parallel Lives

Malcolm, Keen-Eyed Navigator

Magmaw

Amorphous Axe

Parallel Lives

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 clever loop turns Magmaw into a lethal engine by leveraging Amorphous Axe to paint your entire board with the Pirate creature type, ensuring Malcolm, Keen-Eyed Navigator triggers whenever Magmaw flings damage at an opponent. Because Parallel Lives is sitting on the battlefield, every single time Malcolm's ability resolves, your Treasure generation is instantly doubled, providing you with a surplus of artifacts to sacrifice. You simply sacrifice a spare Treasure to pay Magmaw's activation cost, use the extra tokens generated by Parallel Lives to float the necessary mana, and repeat the loop to incinerate the table.
