I've thought about this since I've gotten my deck, and there really isn't any cards that "scare" me or creep me out. Of course certain cards in any deck can frighten me depending where they come up in a reading though. But just going with the images, no not a one.
I do know the woman in the Lovers is creepy, only because she's so errrr bug-eyed ugly!

I really dislike the looks of that woman.
