Seems pretty run of the mill to me maybe just switch out toxic on excadrill for rocks but since you already have a Pokémon for rocks you can really leave it alone. Maybe switch out shadow sneak for something else since limiting your move pool to 2 types can be easy for your opponent to play around mim
