Hi, first post! :-P Um, ok. :-D

I had the same thought as the OP, and wanted extras of certain cards, specifically, but, yeah, getting whole X of release was too much money, so I went searching online and found this site. It's pretty bare-bones, so there aren't pictures or anything, but I was able to find what I needed. I think they're being shipped on Monday, so I'll let you know what happens with that. If it works out, it's awesome, because I think a lot of people might not want dupes of every card, but will probably want to fine-tune certain decks (like me...I don't have any interest in how the Beastmaster plays, for example, so I don't really need anything pertaining specifically to him). Anyway, blah. I'm kind of a ranter, haha. Maybe I'm speaking too soon? I'll update when I get my order and everything.
