How it works

1. Activate Urza by paying 4, creating two token copies of Prized Statue that are 1/1 Soldiers in addition to their other types.
2. When the Prized Statue tokens enter the battlefield, they trigger, creating four Treasure tokens.
3. Activate four Treasures by tapping and sacrificing them, adding 4.
4. Repeat.
