Sakashima of a Thousand Faces + Aethergeode Miner + Aetherstorm Roc

Sakashima of a Thousand Faces

Aethergeode Miner

Aetherstorm Roc

How it works

1. Activate Aethergeode Miner by paying EE, blinking it.
2. Aethergeode Miner enters the battlefield, triggering Aetherstorm Roc and Sakashima of a Thousand Faces, causing you to get EE.
3. Repeat.

This clever loop gets its engine running thanks to Aetherstorm Roc, which acts as our energy generator by rewarding us with {E} whenever any creature enters the battlefield under our control. With that steady flow of energy, we can fuel Aethergeode Miner's activated ability to repeatedly exile itself and return to the battlefield, generating an endless stream of creature enters-the-battlefield and leaves-the-battlefield triggers. The secret ingredient that pulls the whole operation together is Sakashima of a Thousand Faces: its static ability bypasses the legend rule entirely, while also letting it enter as a copy of the Miner if desired, though its main purpose here is ensuring our board state and triggered loops can scale infinitely without interference.
