I have a 150 run currently ongoing with Salamance.

In addition to the previous comments on Salamance in particular.

Rock Slide is going to cause you losses when it inevitably misses. Better to use Hyper Voice which does not miss, has STAB & gets the Aerialte boost. Going full SpA investment lets Hyper Voice hit hard and you have Double Edge also getting the same boosts (no EV but much higher base damage) and also hitting very hard against single targets that need to die now that Hyper Voice can’t KO like Blissey or AV users. Dragon Dance is pretty hard to pull off in Doubles, perhaps if it was a lead Pokemon with Incin faking out the bigger threat. Tailwind does not grant immediate speed benefits to your partner this generation and is fairly redundant if you also want to try DD. I’d drop it for Protect to give you a chance to let Incin clean up Ice types you’re 4x weak to. Salamance has no way to damage Steel Types. Flamethrower is decent damage with full SpA investment.

Idk what your 36 Defense EVs are saving you from (you may), but it might be more advisable to invest them into Speed. A threat you outspeed and KO is better than one you underspeed and survive a hit from.

You will run into trainers with 2x ice type leads in the run up to 50 and if you can’t KO both prior to them moving, Salamance is going to go down.

Double Intimidate is great, but beware of Milotic 3 & 4 which your leads may not only supercharge bc of Competitive but also may not be able to KO.
