There are many cards included in the deck, such as The Emperor, or Cloud of Darkness - boss characters who appeared throughout the FINAL FANTASY series - with powerful new abilities, to be used specifically for Boss Fights.In addition to the pre-constructed deck, there are 17 cards that you can use to change the difficulty level, to make the boss deck stronger, and make for a more challenging fight.
