May's 60-card booster set, Dark Saviors, gives a classic horror movie monster the powers it's known for and introduces brand-new Deck themes for both novice and advanced Duelists! All of the necessary themed cards for each of these Decks can be found in Dark Saviors, but they can also be augmented using cards from Flames of Destruction, Extreme Force, and Structure Deck: Lair of Darkness.
