I remember all the cards from ccg's, LCG's and just plain card games that were never used due to building a "killer" deck.
So years ago I developed what was termed the "Generic" card game
The basic rules are simple:
Add the number of basic colors (not shades) to any numbers printed on the card and that is the cards strength.
Play with "war" rules, highest card wins, one with most tricks taken when you run out of cards is the winner.
The advanced rules require a calculator and creativity.
black x1 number total
brown x2
red x3
orange x4
yellow x5
green x6
blue x7
violet (purple) x8
grey x9
white x10
multiply it out for each color on card and add it up
then roll a d10 and each time you play a card and divide the card number by the d10 number and that is the strength during that play.
About the time you do this you stop and wonder why you are wasting all your time doing this and grab out 2 tylonal for your headache along with a different game to play
