Don't forget Garchomp. It is one of the best Pokemon for a number of reasons. It was banned to Ubers in competitive gaming, but it works wonders in the battle facilities in the games. It all depends on what you plan to do.

I am not sure. I have never participated in the VGC, but from what I know, they have a ban on different Pokemon than in usual online competitive battling. I would guess Garchomp is not banned from VGC, though I do not know how the rules have been for earlier seasons.So do you think that Garchomp will be banned to the Uber tier as well in the up coming 2011-2012 VGC play?
You should use Houndoom or Floatzel because they are great and quite fast. Maybe even Absol.
