Malcolm, Keen-Eyed Navigator + Magmaw + Doubling Season + Psychic Paper

Malcolm, Keen-Eyed Navigator

Magmaw

Doubling Season

Psychic Paper

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 relentless damage-dealing engine by constantly recycling your own permanents. To get the gears turning, Psychic Paper is attached to Magmaw to grant it the Pirate creature type, ensuring that any damage it deals will trigger Malcolm, Keen-Eyed Navigator. With Doubling Season sitting on the battlefield, every single time Malcolm triggers from that damage, it generates twice as many Treasure tokens to fuel Magmaw's activation cost. By sacrificing one of those freshly doubled Treasures to Magmaw to deal 1 damage to an opponent, you start the loop anew—infinitely pinging your foes to victory.
