Extravagant Replication + Capture of Jingzhou + Mnemonic Wall

Extravagant Replication

Capture of Jingzhou

Mnemonic Wall

How it works

1. Cast Capture of Jingzhou by paying its mana cost, causing you to take an extra turn after this one.
2. Move to your next turn.
3. At the beginning of your upkeep, Extravagant Replication triggers, creating a token copy of Mnemonic Wall.
4. When the Mnemonic Wall token enters the battlefield, it triggers, returning Capture of Jingzhou from your graveyard to your hand.
5. Repeat.
