I think the bonuses from monster cards are a bit weak. What good does +1 jump do me? Might be worth looking into buffing some of the lacklustre ones so it's actually exciting to find the card. Just to be clear, I'm talking about individual card bonuses you get whenever you pick up a card and not the exp bonus when you complete a set. Some of them are nice, like increased resists or something, but ones that add like +1 speed? Totally worthless. ETA: I don't really have an ideas about how these could be buffed or changed. Just remarking that finding a card should be exciting beyond just grinding to complete a set. It would also make finding cards again exciting (after you complete the set).
