A good team for a video walkthrough.

[Porygon Z]

Hi guys, help me to point out a good balanced team for Pokèmon White, I want to do a walkthrough once it comes out the Italian version. Also for some good movesets.
Just keep in mind I want to use Serperior and Vanilluxe.

Sorry for double post.
I've thought about a couple of teams.

What do you think about?
If you have to change or mix something, just stay with Serperior. And Vanilluxe, possibly.
