Oh wow, this is really clever! I like the way the cards and dice intermingle, and how you can never feel fully safe with your key spread, even if you get lucky and have 13 cards in a row!
Plus, the fact that the game ends after three rounds and that everyone can lose means that it's a fast-paced game where you won't feel terrible if you lose and can just play again.
Very well done, and congrats on your first card game (and first game for four people)!
