Just got back, made it to round 4 then lost some bad luck with missing a Toxic and Draco Meteor that were crucial to me winning (Toxic early in the game on a scarf'd-ogre which I needed to continuously weaken it's Spout and Draco Meteor to kill Mewtwo which since it missed it turned around and killed my RayQ with ice beam).
Very fun, glad I was able to compete unlike last year because of the lottery.
For people wondering I was running
Rayquaza Blissey lead
Cresselia Groudon in reserve
I'll write up more detailed stuff later.
