Aetherstorm Roc

How it works

1. Activate Aethergeode Miner by paying EE, blinking it.
2. Aethergeode Miner enters the battlefield, triggering Aetherstorm Roc and Blessed Sanctuary.
3. Resolve the Blessed Sanctuary trigger, creating a 2/2 Unicorn creature token.
4. The Unicorn enters the battlefield, triggering Aetherstorm Roc.
5. Resolve both Aetherstorm Roc triggers, causing you to get EE.
6. Repeat.
