It goes without saying that a majority of the stat buffs given to Shuckle from this Mega-Evolution all went into Defense and filled it up so bad it rivaled Blissey's HP stat, with all of the surplus points going into Special Defense and HP. Shuckle was never meant to attack or outright outspeed anything, if anything, Shuckle is meant to stall.
Serena realizes this, and takes full-well advantage of it.
Due to being faster, Edgy hits Mega-Shuckle first with a neutral Close Combat, boosted by both STAB and Adaptability. Unfortunately for Korrina, it does little to Mega-Shuckle's health, he still stands tall, and pissed too.
Next, Mega-Shuckle executes Power Split, connecting an orange beam between both him and Edgy that nicks the jackal's EXTREMELY high Attack stat down to a low pathetic 20.
"Lovely."
