In this game everyone has all the same cards, and they list on them a power that takes effect in the first round of the game, one that takes effect in the second, and one in the third.

Each one gets better the longer you keep it, but you can only play each card once, and you always have to play a card.

Or something like that. Maybe it's rounds "1,2,3", "4,5,6", "7,8,9" or something.

Either way, it's a tradeoff between immediate effects and later effects.
