So if we count Awaclus, we have 14 here. I am thinking we do 16 person, double elimination, and we leave 2 slots open (the 8th and 9th seeds). If no one takes them, the winner of 1v16 gets a second round bye. If two more people sign up, yay, there's room for them to play!
I'll throw a bracket together tonight, probably. Just gotta get a bunch of Iso ranks.
