Well the Aldieb leader guy beat me 2-0 and he was kinda a douche but I beat this other leader Aoki 2-0, it was a good battle but he was using a sandstorm team and I had 2 or 3 UU. Also, this guy named CJ was really cool and offered to make me a prof pic for the chat site they use. http://www.serebiiforums.com/showthread.php?t=483704 is a link to the clan page which has instructions on how to sign up if you wish to do so and http://xat.com/beastsofthenightclan is a link to the chat site the which you will be added to once ur accepted and stuffs.
Yeah, I definitely wouldn't recommend the casual battle forums. I got into a pretty big clan and could definitely get you in as you are leet. Some of the people seem like dicks but others seem pretty friendly so its all whatevs, I bet you could take the leaders pretty easily. If you're not interested its no big deal, only reason I joined was cuz mozarch recruited me and I've been looking to find more battles.
