@Blitzle You mean Head Smash? That'd be lethal in a Hone Claws set, what with the then-fixed accuracy; then you have a drawback-free wrecking ball of a Rock STAB. Brave Bird would also destroy things left and right.
Here's the set in my head:
Jolly / Life Orb, Leftovers, Lum Berry, or Babiri/Passho Berry / Rock Head
252 Attack / 4 Defense / 252 Speed
- Hone Claws
- Head Smash
- Brave Bird
Blindingly fast with 394 Speed and razor-sharp with 463 Attack after one Hone Claws (601 with Life Orb) and STABs packing 225 and 180 power respectively, this thing will tear opponents apart in the blink of an eye when set up. Both STABs are resisted by Steel-types, with Earthquake does a good job covering. The list of item choices is actually pretty wide. Life Orb grants a substantial power boost, Leftovers increases longevity (especially with the Sandstorm immunity), Lum Berry foils a status attack, and Babiri/Passho Berries allow it to survive one of two nasty priority attacks: Bullet Punch and Aqua Jet, respectively.
