Mega Skarmory

Mega Skarmory has the advantage of being able to act in two different types. But oh boy, there are not types that most Pokemon want to compete in! First we have Steel. Still is dominated by Zacian, Zamazenta, and Dusk Mane Necrozma, so it can be hard to fit it in. Its one advantage here is the fact that it's a Mega Evolution.... but guess what? Mega Metagross is a thing. So how about its Flying perfor-.....oh, right. Mega Rayquaza exists.

Mega Skarmory is an okay early-game Mega for pulling double duty, but that's about it. The only other thing to do is grab one and give its talons a clip, because wow this poor bird CANNOT be comfortable!
