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

Medomai the Ageless

Alesha, Who Smiles at Death

Altar of Dementia

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 Altar of Dementia by sacrificing Chameleon
6. Repeat each turn.

This ingenious loop twists Medomai the Ageless's restriction against attacking on extra turns by using Chameleon, Master of Disguise to create a fresh, nonlegendary copy each time. By leveraging Alesha, Who Smiles at Death's ability to resurrect the shapeshifter directly from the graveyard into an attacking position, you bypass Medomai's normal limitations and trigger its extra-turn ability reliably. Finally, Altar of Dementia provides the necessary sacrifice outlet to send Chameleon back to the graveyard between combat phases, ensuring you can repeat the process indefinitely.
