Malcolm, Keen-Eyed Navigator + Magmaw + Amoeboid Changeling + Peregrin Took

Malcolm, Keen-Eyed Navigator

Magmaw

Amoeboid Changeling

Peregrin Took

How it works

1. Activate Amoeboid Changeling by tapping it, causing Magmaw to gain all creature types 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 Pirate with the help of Amoeboid Changeling, granting it all creature types so that its own damage-dealing ability triggers Malcolm, Keen-Eyed Navigator. Every time Magmaw flings a nonland permanent at an opponent, Malcolm rewards you by generating loot, which Peregrin Took happily supersizes by tossing in an extra Food token alongside the Treasure. By cycling the mana from that Treasure back into Magmaw's activation cost, you can repeat the process indefinitely to burn out the table.
