Malcolm, Keen-Eyed Navigator + Magmaw + Maskwood Nexus + Stridehangar Automaton

Malcolm, Keen-Eyed Navigator

Magmaw

Maskwood Nexus

Stridehangar Automaton

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 fascinating loop transforms a modest sacrifice outlet into a lethal engine by turning every permanent you control into the fuel you need. With Maskwood Nexus granting all your creatures every creature type, Magmaw counts as a Pirate alongside its ability to sacrifice nonland permanents to deal damage. When that damage hits an opponent, Malcolm, Keen-Eyed Navigator triggers to generate Treasure tokens, which Stridehangar Automaton enhances by sweetening every token creation with an additional 1/1 colorless Thopter artifact creature token. You then sacrifice those very same Thopters—alongside the Treasures—to fuel Magmaw over and over again, looping endlessly to deal infinite damage to your opponents.
