Jynx is long overdue for an evolution in my opinion. The ones I would want to see are Jynx, Qwilfish, Stantler, Corsola, Girafarig, and Tropius. Some Pokemon Should Not evolve though, but I wouldn't mind seeing these. At least 2 of the ones I mentioned.
EDIT: The Jynx evolution should be a big fat ice queen. It already has decent Sp.Def, so making her a fat queen with big lips and giving her higher sp.def would make sense. Her fatness sponges attacks. ^.^
