They need to be worth more MGP in my opinion though. Selling a card for 5mgp is just depressing. You need 100x times that for an equivalent rank 'random' bronze. Even if you lucked out on rare cards, they're only worth a maximum of 50 MGP. When you earn more by punching a 'cur' in the gold saucer than you do for all the wins it took to win that one card you can't use, it puts things into perspective.
