Truely rare stuff, like Asian Foils, and Beta Blue Duals are scarce, and tend to be what really impress me. Beta Duals and Asian Foils actually require a fair amount of searching out to find, and are what catch my eye when I look through a trade binder.
Is this why you guys kept after my Japanese foil Deep Analyses?

For instance, tomorrow at SCG Chicago compare the number of pieces of Power floating around to the number of Beta Duals, and I think that one would find far more Power circulating around than Beta Duals. Not to mention many more Black lotus than Foil Asian Goblin Welders. That is just one man's opinion, but collecting Power does not impress me much anymore.
I saw more Beta duals than I saw
Beta power, but that's because I happened to walk past one of your games. And foil Asian Welders? Well, counted zero there.
There's a reason for this though - there are less players collecting power than there are players going for 50 playsets of foil Goblin Welders. And even then, there's very few people who do.
I, for one, would sell that shit. The cash would interest me far more, and I'd be making someone happy (c'mon, who wouldn't be happy to get some of that stuff for some money? Hell, money's still in print).
Most of the people I know don't collect a certain card because of it's value. For instance, one of my friends has a few pages, front and back, of foil Shepherd of Rots, and if you think about the flavor of the card, you could understand why. Then there's the guy with like, 300 Clones.
