I'm relatively new to competitive battling. I'm also new to this forum so excuse me if I broke a rule I'm not aware of or something.

there's virtually no reason to run drill run over earthquake on excadrill

If you're running hex, run special Dragapult.(I can't believe that I'm suggesting this, I love physical Dragapult) Change dragon darts to Draco meteor then u can pivot out with u turn.then change it to either timid or modest with 252spa/252spe/4hp. May consider changing thunder wave to will o wisp for physical bulk. Facade is really powerful on conkeldurr so I advise u to swap a move out.
