Malcolm, Keen-Eyed Navigator + Magmaw + Runed Stalactite + Stridehangar Automaton

Malcolm, Keen-Eyed Navigator

Magmaw

Runed Stalactite

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 a 1/1 Thopter artifact creature token and a Treasure token.
3. Activate a Treasure by tapping and sacrificing it, adding 1.
4. Repeat.

This clever loop centers around transforming Malcolm, Keen-Eyed Navigator into a honorary Pirate via Runed Stalactite, ensuring that any damage dealt triggers a steady influx of artifact tokens. Thanks to Stridehangar Automaton's replacement effect, each newly created Treasure token comes paired with an extra 1/1 Thopter artifact creature token to keep our engine well-fed. We then turn those disposable tokens right back into fuel using Magmaw's ability, which lets us sacrifice a nonland permanent to ping an opponent and restart Malcolm's treasure-generating trigger. It's a closed-loop artillery system that converts mana into endless damage, death triggers, and mechanical artifacts.
