I went 6-3, 7-0, 7-1, 7-2, 6-3 with this list. (Something like that, I can't remember the rounds exactly.) I'm sitting at rank 14 right now, but probably not for long. At least two losses were due to horrible gameplay punts on my part.
The list is obviously pretty greed, but most people in the event seem to be playing slow decks, and you'll probably win the late game when you play bomb after bomb. You can survive against fast decks if you draw Hailstorm or Kothon or friends.
