I've been playing since 5th just came out, but I've never had enough money to really get into it, though I attempted to last year in Type II. Considering how little I played, and that my Affinity deck only had 1 Ravager, I was quite impressed that I hit top 2 in several different smaller (16-ish people) tournaments, despite most of them having, you know, decks that were actually finished. I didn't even have a sideboard. :/
Most people just don't know how to play the game. I'm a good player, but don't have the money to squander... especially for limited and such. Which is too bad, since it's really a lot more fun than Poker, which seems to be the "in" game amongst college students.
