A coworker recently got me hooked on Magic: The Gathering. We play pretty much every day over our break. I can't believe I'd never gotten into this kind of game before. Does anyone else around here play?

We're playing modern, and I'm trying to build budget decks (<$30). I just can't justify spending hundreds of dollars on a card game. If anyone else here plays do you have any good ideas for decks that fit this?
