According to the events calendar there are also Championship Qualifiers this weekend. Several rounds of play are happening through Sunday if you're interested in participating. At the end of the weekend's play the top two places will have a Match Play Constructed Deck playoff to determine the winner for the ultimate prize: $500 USD, a "Bye" into the 2008 Legends of Norrath Championships, paid hotel and air travel to Gen Con Indy, 4-day Gen Con Indy badge, and the winner's likeness on an upcoming Legends of Norrath game card. And second place is $750. So ... not bad for a weekend's work.
Good luck, card players.
