Hi, I think if you have two players in the game each person should get half the deck. One player would get hearts and diamonds, and the second player would get clubs and spades. I don't see why half the deck shouldn't be used. Or, why not have a choice factor in the game so the player can choose which suit is preferred?

Like the game so far. Cool rules. If two players play a queen, they should cancel each other out, otherwise you could be waiting forever for each other to play the next card since two people can see the other cards. Hope this makes sense.
