How it works

1. Activate Urza by paying 1, creating a token copy of Prized Statue that is a 1/1 Soldier in addition to its other types.
2. When the Prized Statue token enters the battlefield, it triggers, creating a Treasure token.
3. Activate the Treasure by tapping and sacrificing it, adding 1.
4. Repeat.
