The Chi. winner used Magnetic Action (he played it when it COULDN'T be played so he wasted it...), Swoop Slash (the BakuCon exclusive card that gives + 100 to Darkus for every ability your opponent plays that turn. Again, a USELESS ability), and his only good card, Shadow Lash.
Swoop SLash actually worked though, he got +300G form using that, I guess they counted abilities in the game though (when I think its actually for the battle)
I think I couldv'e easily beaten Abel, anyways, the hardest brawl I had was on saturday, in the battle for day 2 champ, their was a 14 year old usin ventus, he had ventus percival 720, ventus lyte myriad hades 720 and ventus altair 710, and used atmos character card, I think it was an average silver, and like this one gold that gave him an ability back from his collection. Then he used The gust or updraft, whichever one is the play on your opponents gate one, stealin', and blue green combine, he was pretty good with abilities, not so much gates, I still won though.
Atmos' gate card is Gold like almost every other one, you might be thinking of Ocean Spray, a very good Ventus card that has a picture of Atmos.
