Progenitor Mimic + Capture of Jingzhou + Mnemonic Wall

Progenitor Mimic

Capture of Jingzhou

Mnemonic Wall

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