You will earn a WPN Promo card if you reach 10 wins + matches played. So if you play everyone and muster up a single win you will get a card. If you play 5 matches and win them all you will also get a card. If you can somehow play 10 matches and win them all then you can get two ... I guess that will have to wait for Season Two.
I'm really not sure what the cards are - possibly Rise from the Grave and Mind Control?? Hopefully we will be able to do this with each season of the league.
Booster prizes remain as before.
