Equinox, The only good balanced tier in the whole game... UU... I might try OU, but I just don't like having a team of 4 dragons and 2 strategy mons... Which normally end up having dragon coverage moves.
Equinox, Well, 70's-80's is my favorite, and early 90's. Generally though, I don't like the 90's much. To the 21st century ones, I'm rather indifferent, with a few exceptions.
Conpetitive as in the Batlle Tower? If that's what you mean, GofD, shinashu, and Mason are currently trying to revive it to its former glory. I'm sure they won't mind if you lent a hand.
Equinox, The same name as well, only with a ridiculously larger post count. I used to be called Samurott before my crappy internet and I trolled everyone.
