Sakashima the Impostor

How it works

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