Progenitor Mimic + Salvager of Secrets + Capture of Jingzhou

Progenitor Mimic

Salvager of Secrets

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