My friend's Shuckle - 614 Defense and 240 HP. (NO STURDY) My Rhyperior - 416 Attack.
My Rhyperior use Rock Wrecker, can Shuckle survive this??? Also REMEBER rock types are x2 to Shuckle!
You shall DIE! Take this Rock Wrecker!! Dam.. PROTECT! haha xD
>252+ Atk Rhyperior Stone Edge (Base 150) vs. 236 HP / 252+ Def Shuckle: 218-260 (90.8 - 108.3%) -- 56.3% chance to OHKO
252+ Atk Rhypherior is equivalent to a Rhypherior with a Attack Stat of 416 236/252+ Shuckle is equivalent to 240 HP and 614 Defense Base 150 Stone Edge is basically Rock Wrecker (Both rock types as well, so STAB is factored).
The simple answer?
