Physical
at the current rate, this poke isn't going to be all that powerful and if we split the stats (and EVs) it will only make it even weaker. We need something capable of forcing switches and it needs to have decent power, so focusing on one attack stat is the way to go IMO. Also, for a scout it is much better to be walled by the few actually good physical walls than by every bulky Water around and other decent walls, simply because most physical walls are steel-typed, making them easy prey for Magnezone. But that is me.
