I'm pretty sure that I have a couple of Wastelands, a Cursed Scroll and probably some less impressive ones, like Stone Rain.
What kind of value do you put on them?
Edit: Actually, I'm thinking about the World Championship cards, not sure if that's what you mean or not. Probably not.
We have a bunch of similars between wishlist inventory http://puu.sh/3w6FT.png. I'm trying to sell at TCG/SCG price. Let me know if you are interested.
