What Mega Pokemon do you want?

What Pokemon do you want to see get Megas? Post your Top 3 and why! 1) Flygon- outclassed by every OU dragon. It has a great typing/ability making it immune to ground and electric moves, so switching in is easy. It also gets U-Turn! Boosting it's speed could make it an awesome scouter/revenge killer. 2) keckleon- it has an awesome design, a super diverse move pool and was a important Pokemon in r/s/e (blocked off a gym and Steven helped you get them out of the way). It could be the next great protean user. 3) Walrein- another great hoenne Pokemon that never really got a foothold in the metagame. We need more good Ice Pokemon.
