since we have the randomizers by element and such, i was thinking maybe:
- 15 random cards
- 10 new release cards
- 10 neutral cards
- 10 cool cards
- 10 elegant cards
- 10 cute cards
- 10 chaos cards
- 5 random crystals

numbers can be adjusted for balance if needed of course! but that gives 8 categories that are pretty easy to snag from the randomizer
