Medomai the Ageless + Alesha, Who Smiles at Death + Shilgengar, Sire of Famine + Chameleon, Master of Disguise

Medomai the Ageless

Alesha, Who Smiles at Death

Shilgengar, Sire of Famine

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 Shilgengar by sacrificing Chameleon
6. Repeat each turn.

This clever loop hinges on cheating out a nonlegendary copy of Medomai the Ageless using Alesha, Who Smiles at Death, bypassing Medomai's typical legendary restrictions and opening the door to infinite turns. By casting Chameleon, Master of Disguise from the graveyard to enter as a copy of Medomai, Alesha can continually reanimate it attacking on each combat step. Finally, Shilgengar, Sire of Famine provides the vital sacrifice outlet to put Chameleon back into the graveyard after it connects for damage, neatly resetting the loop so you can repeat the process every turn.
