My apologies for a lack of info on the last couple of tournaments.
Proving Grounds are the league play of Shadowfist tournaments.
We're running the first South Bay Proving Ground this spring at Match Play in Mountain View. The season consists of six tournaments, alternating between two player and four player formats. This means you can miss a tournament with no effect whatsoever on your score. That'll be the prizes for the season as a whole. We're going to start off with a Golden Gunman for the first tournament winner.
