My girlfriend has a colorless RH Dialga from PL (I think...).
Also, I bought a Rebellion theme deck that had 61 cards. There was a bonus psychic energy.
EDIT: Oh, and I have a lot of mis-cut cards. Some awfully mis-cutted, like Slowking GS and Giratina PL (Dragon Breath). The other ones are Steelix Prime, Feraligatr Prime and... err I dunno, I kinda forget now...
it seemed to me that all phanpys at the pre-release had the misspelling error, but after the set was released only the RH had the error. I saw someone with a RH tv reporter from ex dragon on Saturday. I also had more of a pack error than a card error; I pulled a german lucario GL out of an english RR pack at target and pokemon sent me three undaunted packs.
The regular rh tv reporter was foil on the picture, but the error was foil on the rest of the card instead, similar to how rh's from dp-on are. I don't know the history of it or where it came from though.
Finally found an error DGX Clash box at a random Toys R Us, but that's not the coolest part. The rare in the Unleashed pack had a double-printed name or something, here's a scan: http://i4.photobucket.com/albums/y132/DDR_hacker/001-1.jpg
I'm trying to figure out what's printed on top of Crobat's name, but I have no idea.
