Medomai the Ageless + Alesha, Who Smiles at Death + Spark Double + Umbral Collar Zealot

Medomai the Ageless

Alesha, Who Smiles at Death

Spark Double

Umbral Collar Zealot

How it works

1. Declare Alesha as an attacker.
2. Alesha triggers, causing you to pay U/BU/B to return Spark Double from your graveyard to the battlefield tapped and attacking as a nonlegendary copy of Medomai the Ageless.
3. Deal combat damage using Spark Double.
4. Spark Double triggers, causing you to take an extra turn after this one.
5. Activate Umbral Collar Zealot by sacrificing Spark Double
6. Repeat each turn.

This clever loop exploits the nonlegendary loophole on Spark Double to bypass Medomai the Ageless's dreaded restriction against attacking during extra turns. By copying Medomai with a nonlegendary variant, you can continuously reanimate it using Alesha, Who Smiles at Death—thanks to Alesha's power-filtering reanimation—to trigger an endless string of combat damage and extra turns. Whenever you need to reset the clone into the graveyard for the next iteration, Umbral Collar Zealot neatly steps in to sacrifice it while setting up your draws with surveil.
