Use it in Uber. no kidding.
Trait: Sturdy (because gluttony have a 0.06% of chance of being useful, if target tricks you a berry, but... and contrary will only be PREJUDICIAL)
EVs: 248 HP, 252 Atk, 8 Def
Accupressure; it's the main move of this set. you will have to use literally 21 accupressures, but once your stats are maxed out, it won't be stopped unless you have a designed counter for it, such as focus sash topsy-turvy malamar.
Power Split; many people begins with their mega. and most mega Pokemon are really powerful. if you strike it on a foe with a very high physical attack, such as mega blaziken or mega mewtwo X, you will get really powerful, and can begin to accupressure.
Rest: you CANNOT leave your HP low. even though shuckle is bulky as hell. rest will bring your HP up to maximum, and leftovers prevides a low cure to heal you up while you are asleep.
Stone Edge: it is your only damage move and is a MUST. if you are maxed out in all stats, all power splited rightly, as I said before, you will not be stopped unless your opponent have a designed counter for it
many epople use this Pokemon alone in their team, but if you really wanna win, you should use this along with other 5 Pokemon. you will become mostly unstoppable.
