Progenitor Mimic + Capture of Jingzhou + Izzet Chronarch

Progenitor Mimic

Capture of Jingzhou

Izzet Chronarch

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 Izzet Chronarch.
3. When the token Izzet Chronarch enters the battlefield, it triggers itself, returning Capture of Jingzhou from your graveyard to your hand.
4. Repeat.
