1. When cycling between cards the lower row (showing the cards not in your deck) sometimes gets out of sync with the upper row (showing cards in your deck). This causes the game to display a card as being in my deck when it is in fact not, and vice versa.
Also, I see no way to add cards that you've found to your deck. The rules say you can have multiples so long as they aren't from the same set, so why can't I add the Aces, etc. to my deck? Right now my inventory is cluttered with extra cards I've found.
