Double sided cards

Double sided playing cards
Double sided playing cards while great for magic tricks are horrible for an actual game. Due the the fact they are useful in one way and that way is their intended use it still serves a use however if one does not have any cards on them good luck trying to play any kind of game with these things. Also magic is not a very useful skill while it is cool it isn't very useful in everyday life so thats another reason it is here.
