The first one is out, because it isn't fair. We want a 50/50 chance to win. If we add 2 cards with stars, then your chance of winning increases too much(as much as that'd be great). If we take away 2 blank ones, it would be fair, but we want to still have 10 cards. So the only choice left is to add a start to 1 of the blank cards.
