Salamence has a large number of sets. You can run a bulkier spread with Substitute or Refresh over Earthquake, a mixed or special set with Return/Fustration or Hyper Voice, Fire Blast, Draco Meteor, and Earthquake or Hydro Pump, or even a mixed DD set with Return, Fire Blast, and Draco Meteor or Earthquake.
Gallade has a couple of option too, it can run Substitute over either Zen Headbutt or Knock Off, while this does leave it walled by either Fairies or Psychics, it enables Gallade to set up over Status users such as Mew and Rotom-W. Taunt is a pretty niche but still viable option which achieves more-or-less the same purpose, while stopping the opponent from recovering.
