Malcolm, Keen-Eyed Navigator + Magmaw + Arcane Adaptation + Stridehangar Automaton

Malcolm, Keen-Eyed Navigator

Magmaw

Arcane Adaptation

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.

By anchoring the loop with Arcane Adaptation naming "Pirate", all your creatures—including Magmaw and Stridehangar Automaton—gain the Pirate creature type, allowing them to trigger Malcolm, Keen-Eyed Navigator's wealth generation whenever they deal damage. Magmaw acts as the sacrifice outlet and win condition, converting any nonland permanent into direct damage to an opponent while fueling itself. Meanwhile, Stridehangar Automaton supercharges the whole loop by replacing every single Treasure token created by Malcolm with both that Treasure and an additional 1/1 Thopter artifact creature token, which in turn benefits from the Automaton's static anthem. This creates a self-sustaining cycle of sacrifices, treasures, and thopters that converts an initial mana investment into infinite damage and death triggers.
