The things that make men's blood run cold. The danger, the darkness, the destroyer, the big bad guy. Yup, that's you!

Play as a mighty Dragon or an undead Lich and take on an entire group of your friends and their pathetic, puny, mortal characters. Or, if you're up for a real challenge, you and a friend can battle these boss decks against each other!

Boss decks include 30 cards. Each boss is unique, having different numbers of cards in their starting decks, different ability cards, and even brand new card types.
