Ace Of Keys
Me and My sketch pad
Definitely Mega Camarupt and Mega Sharpedo due to their power ups and the fact they're the ace pokemon of their respective team's leaders. Plus their aesthetics are a nice touch
Mega Altaria is my personal favorite. Altaria has always been a favorite Pokemon of mine but I love the fact the fact that it got a mega in ORAS. It's typing is really good. I used one in my OR game and I was surprised at how good it actually was.
I agree how good it is. Its Mega has made it better in competitive because of its unique typing + better investment into improvement of its stats (except for Speed), making it shoot up to OU and when I tried it in the Battle Institute, it survived in all battles except for the last one.
