It doesn't really need to be added. It just makes it faster for you to quit matches that you know you have a bad hand in. Also would make it easier to win trade if it went towards a win. Or the player could just quit before the match is over. Doing NPCs with random card rules sucks I know im at 146cards. Its just something you gotta deal with. Wish they added another card rank or added something for collecting more cards in the game.
