If cards need to be pulled out of the expansion to keep the game less confusing and maintain fun, then there is an issue. This set released some new cards that are enjoyable to play but we have to put this expansion lower due to the Curse of Cat Butt. The backs to the cards are designed only for the main version of the game so party pack players beware. Streaking Kittens is the set that released the curse of Cat Butt as well as several other cards for the game.
