Probably. There is plenty of room in the box and a card or two adds effectively nothing to the printing cost, so that just makes it a design problem, which I'll start tackling this weekend. Just so everyone knows, I do plan to make a more detailed, pretty and slightly more fun PDF guide which will be free to all backers if we fund. I plan for it to contain images of the cards, classic effects desciptions, suggestions (worthy of ignoring) on how to DM some of the cards, plus a thank you page to all backers, little bios of the face card backers, and a centerfold of a goblin in a bikini. NO! That was a dream I had last night... can I still edit this?
