I personally think the Pokemon win, they have a metal snake, a woman that can make black holes, neutral ground for not only this, but also the other billion lions debate, and a Pokemon that can transform into other 'Mons and even another lion, all this, and more.
the only way the pokemon lose is if they run out of PP but that's not a big deal if one singular pokemon uses erupt or something that can cause a huge aoe like surf, earthquake, or some other natural catastrophy based attack.
