Hundred Demons already have their own seperation method.

And its not really crammed. They just use the spot for exess flags, and Yamigedo. If you are saying that 10 extra cards is making it crammed, then that is actually your own problem.

Generic is going to continue harboring the attributes flags, as they are not worlds. If a new world is introduced however, then that world will be added on the slot list.
