MtG: 15 Best Streets of New Capenna Cards for Commander

Professional Face-Breaker

This card has a terrific synergy with Prosper, Tome-Bound in commander, when you get the following combo:

1. Play Professional Face-Breaker.
2. Play Prosper, Tome-Bound.
3. Attack with Professional Face-Breaker, creating treasure token.
4. Sacrifice Treasure Token to exile a top card of your library.
5. Play the exiled card.
6. Create another Treasure Token with Prosper, Tome-Bound.
7. Rinse and repeat steps 4 through 6.

Obviously, it's going to be really hard to go infinite, but with the help of mana rocks from the top, you can still achieve much in just a single turn.
