It's Time To D-D-D-D-D-D-Change out your deck man

"You've had it for awhile and it's starting to smell." Are you still willing to risk eating it?

I once had an idea of making one of those giant rectangle party pizzas and cutting it into playing-card-sized pieces and using toppings to make the numbers and suits, like a 3 of mini pepperoni or a 7 of olives, etc. And then you could play War with them. Except if you beat the opponent's card, you don't add the cards back to your deck, you just eat them. So you have to fight to eat, and if you lose the war, you starve.
