Knock Off I believe is mentioned in the OO part of the current Gliscor analysis. Torment is garbage unless you have really good typing. You'll only ever see it on Heatran due to its resists, and even then I never see it on Heatran. Bulldoze could certainly be interesting but even then you're not gonna hit really anything that won't KO you in return. It's annoying at best, honestly it's better to setup rocks or Toxic.
As for the weather options, they're all best left to Bronzong.
