I have a couple of dumb questions. I am fairly new and don't mind playing the DPA decks. My questions are when I click on the Theme Decks to play one of them there are alot of different series' listed. Are the older decks available to buy to play or is just the newer sets is all that is available? thanks for any help. To me it would seem easy enough to make them available as decks and a money maker if people wanted to buy them.
