Malcolm, Keen-Eyed Navigator + Magmaw + Primal Vigor + Psychic Paper

Malcolm, Keen-Eyed Navigator

Magmaw

Primal Vigor

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 loop relies on transforming unassuming pieces into a lethal engine, starting with Psychic Paper equipped to Magmaw to grant it the Pirate creature type. Once Magmaw is a Pirate, its activated ability can be used to sacrifice a Treasure token, paying its own cost while dealing 1 damage to an opponent and triggering Malcolm, Keen-Eyed Navigator. Because Primal Vigor doubles all token creation, that single point of damage yields two Treasure tokens instead of one, providing a net gain of mana and fodder. By continually sacrificing one Treasure to fuel Magmaw and banking the extra token, you can repeat this cycle to deal infinite damage and incinerate the entire table.
