There's a little blackmarket trading going on with cards right now, over in the 'moo me!' group.

Send one of your cards out into the world and receive another in return. With 10,000 free packs out there and countless 100 packs, that's a lot of mail before you collect the set!
But some of you like your cards way to much to give them up... and to be honest, with some of the amazing stuff we've seen, we don't blame you.
So, what are you doing with yours? (Personally, I kept half and gave half away. I'm good like that, you know).
