I'll try to be Snivy as a starter, and I'm deciding between Oshawott and Axew for Partner. There is no way those other two are ever even coming close of getting on my team, other than completion purposes.
This is in no way the ending list, there have got to be some more partners coming. (Cubchoo, Zorua, Munna, Drifloon, Ralts, Elektrike)
EDIT: Rank Up! Yes! That's two badgesM
