Mega Mawile is a Steel & Fairy type, and has a great design, love this much better than regular Mawile. I also love how Mega Mawile is not useless in battles like regular Mawile, as it got decent stat buffs, and a decent ability of Pure Power, which makes it even more deadly. Mega Mawile is great and all, but just wasn't enough for it to pass the other 6.
