@Spydyr: Yes, final forms are okay. Probably best to not use all evolved forms, or put some limit on it, though (maybe your Pokemon doesn't like you, or is really stubborn) so your power doesn't get Mary-Sue-ified. I have to do the same for my own lineup, because if I don't watch out, I tend to go for the biggest, baddest, meanest ones I can find.
@Phi: yeah...you're right.
