Duskmourn: House of Horror is a Magic: The Gathering set set entirely inside a single, sprawling, nightmarish sentient house that has swallowed a plane whole. The set leans into survival-horror tropes with room-based enchantments that represent moving through the house's corridors, plus a cast of monstrous villains and desperate survivors. Its horror-movie aesthetic and room mechanic make it a standout, atmosphere-driven release. Shop Duskmourn booster packs and sealed product, or browse singles from this horror-themed set.
