/* So for the card objects, I needed them to be properly sorted
   which is why they let you specify the layer index when creating a new card object.
   Since the cards would overlap a lot in your hand, If they weren't sorted properly, it would look like a mess.
   The joker objects are functionally identical to card objects, so they use the same logic.
   But I'm going to use a simpler approach for the joker objects
   since I'm lazy and sorting them wouldn't look good enough to warrant the effort.
