When you draw a specific type of card instead of from your deck, that card could have a different back. That way your opponent could more easily keep track of what kind of cards you have. So differnt backs for werewolf cards, vampire cards, spirit cards, zombie cards, Melee Laser attack cards, Magic Laser Attack cards and Laser malfunction cards. So on the back of werefolf card maybe there is a werewolf or whatever. It already possible to know how many of these cards your opponent have by keeping track of what cards they discard etc, but that is tedious.
