Registeel uses/EV spread/moveset?

[LethalTexture]

My PalParked Registeel has been sitting in my box for months. May 2nd to be exact. And I've just noticed it is Impish and capable of taking hits. This screams out for a Physical Wall. Any suggestions on him?

every registeel needs tbolt/thunder and hammer arm/earthquake to take care of threats.

boosting its defenses is pointless when you can't do any damage to them anyway.

Hmm. So, would you suggest:

ThunderBolt
Explosion
Earthquake
Thunder Wave/Stealth Rock/Toxic
