I know you're all tired of me posting Pokemon in here. I'm not sure about the moveset, whether to go special or physical. Physical Registeel @ Leftovers Impish Clear Body EV Spread - 10 HP, 100 Attack, 200 Defense, 200 Sp. Def - Iron Head - Earthquake - Iron Defense/Amnesia - Protect/Stealth Rock/Toxic/Explosion Special Registeel @ Leftovers Bold Clear Body EV Spread - 10 HP, 200 Defense, 100 SP. Atk, 200 Sp. Def - Flash Cannon - Thunderbolt - Iron Defense/Amnesia - Protect/Stealth Rock/Toxic I'm leaning toward Amnesia for the 3rd slot because the nature will help defense. It's going to be my wall if this means anything to with your advice.
