Serperior looked so cool to me and is one of my favorite Gen 5 Pokemon. Why don't we give it a mega? It has decent bulk, decent HP, decent attack and special attack, and amazing speed. It is commonly known for it's contrary Leaf Storms that can put a dent in some Pokemon. except Heatran and most types that resist grass. So if it got a bit bulkier and got more attack/special attack, it will be a force to be reckon'd with. With Protean you can have STAB on all moves that your Serperior carry. A move set you can have on Mega Serperior can be: Leaf Storm, Dragon Pulse, Hidden Power Fire/Ground, and Protect/Taunt. With this move set you can set up a Leaf Storm using your previous ability (Contrary), then Mega Evolve to use Mega Serperior's boosted stats. With boosted defenses and boosted attack stats, but shallow movepool, Mega Serperior will be used to sweep and tank a few hits.
Tell me whatcha think ^3^
