Medomai the Ageless + Alesha, Who Smiles at Death + Thermopod + Chameleon, Master of Disguise

Medomai the Ageless

Alesha, Who Smiles at Death

Thermopod

Chameleon, Master of Disguise

How it works

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

This clever loop turns Alesha, Who Smiles at Death into a relentless engine for infinite turns, relying on her ability to resurrect Chameleon, Master of Disguise from the graveyard tapped and attacking as a copy of Medomai the Ageless. Because this cloned extra-turn trigger bypasses Medomai's original restriction against attacking during extra turns, the copy can safely swing and trigger again every single turn. Finally, sacrificing the copy to Thermopod before combat ends allows you to bin the creature cleanly so Alesha can bring it right back on the next swing.
