Progenitor Mimic + Warden of the Eye + Capture of Jingzhou

Progenitor Mimic

Warden of the Eye

Capture of Jingzhou

How it works

1. Cast Capture of Jingzhou by paying its mana cost, taking an extra turn after this one.
2. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Warden of the Eye.
3. When the token Warden of the Eye enters the battlefield, it triggers itself, returning Capture of Jingzhou from your graveyard to your hand.
4. Repeat.
