Anyway, those are the important points:

1 - By defeating an enemy and getting the card, you'll gain a small boost in your powers. The more cards the more powerful you'll become.

2 - The Minor Arcana aren't meant to be useless cannon fodder. Sure, they are silly and all that, but they are meant to be at least a credible threat, since they will be some of the only enemies on this RP, other than the corrupted Major Arcana, who are truly dangerous foes.

Keep that in mind fro now on, since it looks like I wasn't specific enough before.
