Well you can only use one mega per team, so eh, good luck with that.
I can't, for the life of me, understand why people would find it desirable to run through a new game with the same, stale Pokemon (mega or not) who have been in the series for over 15 years. With that in mind, I'm going for an entirely Kalos-based team. So far, I know for a fact that I'm using Skrelp, Spritzee, the Amaura line and - if the new set of rumours are true - the Ground-type badger.
Per battle, not per team. I like to shake things up. Also, I care more about the new adventure, gameplay mechanics, and plot than I do new pokemon. Froakie's all right, but I have no fond memories with it. Give me old pokemon in a new game, and that's an instant buy. --- Mewtwo, Charizard, Sora, Cloud, Roxas, Shadow from sonic, Heartless from KH, K.K.
