Aggron @ Choice Band
Ability: Heavy Metal
EVs: 252 Atk / 4 Def / 252 Spe
Adamant Nature
- Heavy Slam
- Earthquake
- Ice Punch
- Fire Punch
Why not just put Heavy Metal to double Aggrons weight? Rock Head doesn't boost any move on the set. Also Aggron already gets detroyed by Low Kick. Sure Grass Knot does more, but using a extra powerful Heavy Slam on a mon that doesn't have Grass Knot is entirely worth it in my opinion. (You could also just put Head Smash on it if you really wanted)
