I miss the old days of pre Time Vault power errata removal, where decks like Welder were prominent. I prefer the old spells rule days and not the current creature heavy meta.
One of my favorite thing about having frequent proxy tournaments is that you can play whatever you want. If you lose, so what? Buy-in was cheap and there's another tournament just around the corner. Everyone else starts to notice this, too. So you have many people bringing "rogue" decks. And you have awesome opportunities to exploit local weaknesses. I noticed players slacking on Dredge hate until I showed up with Pitch Dredge. Others focus on fun. We've got a guy planning to bring Gorger next time around because if he's going to play Vintage, he wants to do the dumbest thing possible.
