I will buy entire collections of Magic cards. Probably no more than 5-10 cents per common/uncommon, and slightly more for rares. I have a few rares from 9th, Planar Chaos and Time Spiral to trade, and I could be coaxed into trading some of my video games (Disgaea for PS2, anyone?)
Really not interested in singles except for a select few (9th Jester's Cap, 9th Birds Of Paradise, AN Juzam Djinn)
