~~~~ With the recent reveal of Mega pokemon, I couldn't resist trying my hand at one of my favorites. I'm not quite sure the details involved as to what changes stat-wise when a certain pokemon mega-evolves, but I imagine that Sandslash would shed a bit of his Defense to boost his Speed and Attack. Once we learn a bit more about these forms, I'll update Mega Sandslash's info.
EDIT 11/2/13: Now that the game has been out for close to a month now, we have a general idea of how the Mega forms work stat-wise. I did my best to divvy up the stat boosts to fit the average total 100 that most of the Mega forms get, plus to fit what I assume would be a straight-up melee fighter. Plus I liked the idea of an ability that totally messes over the competitive types who spam wall pokemon. : p
