This is a fan made Nightmare Expansion Set. (not the original but a reprinted one) 150 cards PLUS the original authentic dividers, nothing else, No book, or box. Just the fan made printed cards, and the dividers.
The original Nightmare set is very hard to find so this is an alternative to be able to play with it for less. The original is out of print as you may know.
The printed cards look good and they're very close to the originals on the front and back.
See the pictures for a side by side comparison to the real cards.
