Wow, those are all real fun (in that murky, creepy, slightly uncomfortable way).
Too bad only one of the three will be included in the deck, but out of all of them, Symbols is probably my favourite. The way players get just a starting point and have to find the horror in that on their own probably works in the game's favour. Also, although simple, I really enjoy the mechanics of acquiring the items—having just one shot at receiving one of the most mundane items on the list somehow makes it feel that much more important, thus, again, stoking the reader's creativity ^^
