aikira21, I agree that the metagame is way too cookie-cutter now - even so than it was before.
At my league people actually do try to play fun or unusual decks (one of my friends who has just moved up to Masters is running Mewbox of all things, and another friend is running Shining Suicune - and both decks work great), and I'm trying to shift to something Vileplume-based myself. Right now I'm running Gengar, since I'm a big fan of gimmicks (most every deck I have run for the past several years is gimmick), and I view Slowking as a staple for the deck (and he's amazing - I was vsing a ZPS at a Worlds side-event, my worst nightmare, and I stalled him out for 7 turns with Second Sight; I lost, but still, Slowking is great, and the Prime isn't half bad either), so that guy has helped me win many a game.
Lock decks are pretty much my favorite decks to see, because even though they're sometimes slow in setting up themselves, they slow your opponent down even more. I think something Vileplume will be good for BRs, because I hate Yanmega with a passion (after going to Worlds and seeing the format for what it was) and since most of the builds nowadays are very Trainer-heavy, I figure either Gothitelle or Vileplume is a good answer. And since Vileplume is much more fluid, I'm going with that.
I miss MD-CoL format so very badly. I played my favorite deck ever then.
