I've been playing MTG since Alpha and as you can see amassed quite a collection.  I'm up for trading just about anything but I won't break up International Collectors Edition, Commander, Commander 2013, Planechase, Planechase 2012, Versus decks, Premium Decks.  Any other set is open season, I prefer to trade newer sets for older cards, specifically I'd like to finish Arabian Nights, Legends and Antiquities.
