So, I won 3 of 5 games, but I got such insane luck in BW2 UU (our final match) that I didn't feel comfortable taking a straight-up win. I decided to let a coinflip decide it. We went on irc, rolled a 2-sided die, and it came up 2. Colcho had called tails (2), so he moves on.
It was really fun to play all 5 metas, and they were awesome games besides the crit-hax. GL in the Finals!
Edit: NM, we're going to re-play the BW UU with the same teams instead of doing a coinflip.
