Played from 3rd edition through Ice Ages. Worked at a card and comic book store in our area and basically signed over half my paycheck every payday. Looking at some of the guys at my work playing the new stuff, I long for the simplicity of trample, first strike, and flying.
Loved making decks. Everyone goes through the same phases of deck making though. "Let's make a flying deck. Now a weenie deck. How about a land destruction deck. Or a control deck, etc, etc."
My favorite deck was an unorthodox three-color deck made up of walls. Playing Wall of Caltrops always got a look from my opponents.
