Nightmare Decks for The Lord of the Rings: The Card Game allow players to revisit their favorite scenarios cast in the shadows of the game's challenging Nightmare Mode. Featuring deadlier enemies, darker locations, and more terrifying surprises, each Nightmare Deck introduces new, alternate encounter cards and instructions for using them to reshape a scenario's encounter deck. The result? A nightmarish journey through territory players thought they knew, but with new twists and turns that will have them on the edges of their seats! Khazad-dûm Nightmare Decks is a single set of three twenty-card Nightmare Decks, one for each of the three scenarios from Khazad-dûm, the first deluxe expansion for The Lord of the Rings: The Card Game.
