I'm making a card minigame. There are about 30 possible positions for the cards to be placed in. It's more the assigning that I'm concerned about, because, while it's possible within the rules of the game to have more than 20 cards shown at a time, it's not very likely. I need to be able to assign the numbers to each potential position, however, to reserve each possible spot and also so that the card continues to be shown after after it's played.
