Re the Fantastiques, there's a lot of possible reasons why they haven't sold out yet. Maybe they made huge quantities, maybe D&D want to have a deck around on a regular basis instead of a special issue that sells out then months of no D&D decks.
Re all that's been said, yes, use your cards. Yes, remember your roots: Bikes, Tallys, Bees, Studs, Aviators, Mavericks - all the "base" brands of the USPC. With all the custom decks and special issues and whatnot, I recently broke out a plain old pack of red Cincinnati Rider Backs. It's not all about buying everything and putting it under glass.
Actually, Dan and Dave claimed that they were very limited, even more so than the V6's.
You are correct in that one. They explicitly stated that. It has been brought up in this forum that it is not exactly known how many were made but they did say the cards had less made than V6. They also made a statement that they expected the cards to be sold out in a week. Anyway, I was annoyed by that whole thing for a little while but they are great cards. Very unique. I guess that is the important thing
