Malcolm, Keen-Eyed Navigator + Magmaw + Unnatural Selection + Peregrin Took

Malcolm, Keen-Eyed Navigator

Magmaw

Unnatural Selection

Peregrin Took

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 a Food and a Treasure token.
4. Activate a Treasure by tapping and sacrificing it, adding 1.
5. Repeat from step 2.

This clever loop turns Magmaw into an honorary corsair with the help of Unnatural Selection, allowing its own sacrificial damage to trigger Malcolm, Keen-Eyed Navigator for a steady stream of Treasure tokens. Peregrin Took supercharges this plunder by appending an extra Food token to every single creation event, fueling the mana-positive loop and giving you extra resources to spare. By sacrificing a permanent to Magmaw and using the mana from Malcolm's resulting Treasures, you can repeat the process indefinitely to deal infinite damage to your opponents.
