I'm mainly opting for capturing regional Pokemon over Unova native, since most of the Unova pokemon I dislike, and the ones I do like, I've used in BW. So far my teams is settled at:
Currently considering an electric type, but jolteon has an icky movepool, which leaves electrivire, which I don't know what moves to give it. xD I usually assign moves as I play, so I suppose it wouldn't be that big of a deal. I'm also considering a grass type, but so far non take my tastes, except for Tropius.
