Giratina-o has the same thing, as in fact a whole lot more related to the mega stone item. I honestly hope if anything, luke's speed is boosted significantly. Idgaf about anything else, if its speed was boosted to say, 110, that would suit me just fine. It may then end up not broken/banned (doubtful, but theres a higher chance if every stat got gradual increases), as this would allow it more effective sweeps, but at a cost of less power.
Im hoping megampharos becomes some aort of tornadus-t like mon, in that its defenses get boosted massively at the cost of a little power. Though i still put ampharos as ru at worst, uu at best. The intro of fairy types really hinders its effectiveness (smh gamefreak). Mega absol at ou, possibly ubers. Mega absol would be so great under dual screens with its coverage moves. And ofc, huge power mawile. Ou/uu :x
