Malcolm, Keen-Eyed Navigator + Magmaw + Runed Stalactite + Elspeth, Storm Slayer

Malcolm, Keen-Eyed Navigator

Magmaw

Runed Stalactite

Elspeth, Storm Slayer

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 relies on transforming your entire board into a pirate armada using Runed Stalactite, ensuring that any damage dealt to your opponents triggers Malcolm, Keen-Eyed Navigator. With Elspeth, Storm Slayer doubling the creation of those resulting artifacts, each sacrifice actually yields a net surplus of Treasure tokens to keep the engine running. Magmaw provides the reliable outlet to convert those sacrificed tokens into direct damage, and since Elspeth's token-doubling replacement effect turns every trigger into a double bounty, you can easily loop this process until all of your opponents are defeated.
