Progenitor Mimic + Capture of Jingzhou + Pinnacle Monk // Mystic Peak

Progenitor Mimic

Capture of Jingzhou

Pinnacle Monk // Mystic Peak

How it works

1. Cast Capture of Jingzhou by paying 3, causing you to take an extra turn after this one.
2. At the beginning of your next upkeep, Progenitor Mimic triggers, creating a token copy of Pinnacle Monk.
3. When the token Pinnacle Monk enters the battlefield, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
4. Repeat.
