I also have a ton of magic cards, I don't know what's considered good/rare anymore, as I got out of it over 10 years ago. Most of my stuff is from the Unlimited/Revised era. I obviously have no use for them, and am willing to trade/sell. If anyone is interested, PM me.
As far as decks go, the only one I think I still have in one piece was a simple basilisk/cockatrice lure deck with force of natures and craw giants...
