Not exactly Boah, because you have Zapdos on your team already, and that covers your Skarmory needs ( I would suggest getting a Zappy with HP grass also as your team has no surefire way of dealing with Swampy).
Maybe just a CB one, or even a curser-which could even prove to be a great special wall, and that's really what you need to cover your weakness to the common Bolt-Beam.
