Following the success of the original cartoon network Crossover crisis deck building game, more of cartoon network's classic characters, past and present, are joining the fray! this standalone game is not only a great introduction to deck building, but also a fantastic expansion for the original set. The new "wonder" keyword brings a childlike sense of, well, wonder to the game as the ability allows players to play a card off the top of the main deck. You never know what you'll get except for a fun time and lots of surprises! the card you play goes straight to the line-up, so if you liked the effect, you can buy the card immediately. The more cards you have to choose from, the better!.
