Medomai the Ageless + Alesha, Who Smiles at Death + Umbral Collar Zealot + Chameleon, Master of Disguise

Medomai the Ageless

Alesha, Who Smiles at Death

Umbral Collar Zealot

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 Umbral Collar Zealot by sacrificing Chameleon
6. Repeat each turn.

This clever loop sets up an endless chain of extra turns by constantly recycling a legendary restriction. By having Chameleon, Master of Disguise enter the battlefield as a copy of Medomai the Ageless, you bypass Medomai's typical legendary cloning hurdles while keeping that crucial combat damage trigger. When Chameleon connects with a player, Medomai's built-in clause to prevent attacks during extra turns would normally shut down the engine, but Umbral Collar Zealot elegantly steps in to sacrifice the copy first, feeding the graveyard so Alesha, Who Smiles at Death can resurrect the whole process again on the next combat step.
