This Duskmourn: House of Horror Bundle contains 9 Duskmourn: House of Horror Play Boosters, plus 1 Traditional Foil card with Bundle-exclusive alternate-art, 15 Traditional Foil and 15 nonfoil Land cards (including 5 foil and 5 nonfoil Full-Art Lands), 1 oversized Spindown life counter, 1 card storage box, and 2 reference cards
