Okay, I just moved and I have no idea if the unopened decks of Guardians that I have are series one or not. I don't really recall buying any other than the series one because I didn't like the feel (I know it was altered later) but I may have as I bought them when I was deployed to Iraq a few years ago. Is there a way to determine which series they are without opening the box? UPC or something? I don't want to open them as I only have 3 decks left and I want to keep the series one sealed. Thanks.
