Still working on the cardgame. I switched it to just a regular 3 way roshambo (blue, red, yellow) and redrew a few cards.
Here is a concept for the top of a card drawn on a Post-It Note. I like putting the number and suit/color pip in the top left like in traditional player cards rather than in the top right like the Pokemon card game or Magic the Gathering. I was originally going to do four suits/colors based on traditional playing cards as well but dropped it for the rowshambo idea.
