I also have oodles of cards tucked away, a full set of revised edition and 3 or 4 decks made up. Love the old green/white Ernageddon deck.
As a result of my younger brother selling away most of my cards and earning me plenty of $$$ I don't have that many left over cards.
My remaining decks though;
Black Creature (mostly small ones, with plenty of ways to take out opposing creatures)
Black Pestilence (4x Pestilence, alot of regeneraters, a few life stealing sorcerys and more swamps than sense)
Green Creature (Something like 30 cheap creatures and a few giant growth-type cards)
Green/White/Red Token Deck (designed to assemble vast armies of 1/1 token creatures, includes my coveted Kjeldoran Outpost).
Mostly Black Raise Dead/Sliver Queen Deck (Pretty much designed around getting a Sliver queen into play without having to pay the silly casting cost...also has a hilariously awesome trick that pretty much = autowin if I pull it off
I also have the cards for a Suicide Black Deck (3 turn wins!) and a green deck full of huge monsters (although I miss my Forces of Nature
Obviously the black and green cards were my favorites - Red and white were alright but I never really liked Blue - counterspells always annoyed me to no end.
