Solid art with several nice designs per set. This is one of my favorite sets of the Mirror Universe line. There's not a whole lot of explication in the origin tales, but it's more than enough for inspiration. You even start to get an idea about the game world, because some of the origins from different sets begin to tie in together. If you already have your own campaign setting, the information isn't so specific that you would have to do much (if any) work to make them fit. Keep these products coming.
