I have to update my previous review. I love this game and have spent many hours playing and building my decks up, but ever since they put a linted anount of keys to llay co-op it has ruined the game for me not all of my frineds are online when i am or free so i have to wait for some keys or for one of my friends to mot be in a game to play co-op?? I do not understand the point of the keys and not being able to just play co-op with random people without any limitations i hope they take them away!
