Has a 60-card deck that can be broken up any of the LCM ways. Uses color, shape and number. These would be visual as well.
While the deck can't be changed, you do acquire spells which consume different parts of the deck and manipulate various things, all with the ultimate goal of dealing magical damage to something.
You have a limited amount of spells you can use per card game, if you don't deal enough damage you lose.
You can also discard N cards, drawing N new ones. This counts as a spell but does nothing.
The deck is basically just a symbol. Cards are therefore probably squares rather than rectangles.
There are six symbols. They're somewhat blocky. While they're distinct from one another, there are some commonalities -- AB,CD,EF as well as ACE,BDF.
Symbols are represented in 5 colors.
Symbols are "inverted" half the time -- instead of being the symbol of the correct color on the bg (likely white or black), it's instead the bg as a symbol on the correct color.
This setup allows for probabilities that use 2,3,4,5,6,10,12,15,20,30
