In ‘94 I was 11 and Magic was blowing up in my hometown - the 3rd (or Revised) edition had just come out. The local comic book stores would have Magic tournaments on Friday nights. Turnout would usually be 30-50 people and it was mostly grown ups. You would play a number of 1:1 matches and whoever had the best records at the end got to a final four. The winner of the tournament would get a high value card.
I played with an all red deck with quick spells to inflict major damage (Fireballs, Lightning bolts, etc…) and Forks to double the power of those spells. The grown ups didn’t like it because “it was a cheap strategy”.
I sold all my Magic cards in college - I really wish I would have kept those.
