My new GAC defense works good for now

What do you guys think about my defense? Until which league could it work? My attacking teams are much weaker, but I have the feeling putting Darth Traya with Omni + Savage with Omni in the defense works perfect. I am Chromium 2. This could be my first GA with 3 wins.
