>>29970710Two different sets I can see working:
>Lycanroc-Midday @ Choice Band >Ability: Sand Rush >EVs: 252 Atk / 4 Def / 252 Spe >Adamant Nature >- Accelerock>- Stone Edge >- Crunch >- Fire Fang/Thunder FangThis a generic Sand Wallbreaker, similar to how Kingdra functions in Rain. Accelerock is handy for picking things off if you don't have Sand up or don't want to risk the Stonemiss, and the choice of Fang move is up to you. Would you rather kill Ferrothorn or Keldeo?
>Lycanroc-Midday @ Life Orb >Ability: Sand Rush >EVs: 252 Atk / 4 Def / 252 Spe >Jolly Nature >- Swords Dance >- Accelerock>- Crunch >- Fire Fang/Thunder FangThis set is much more late-game oriented, with SD and ideally some prior damage done to the opponent to make up for the lack of Choice Band. While you can go Adamant on this set as well, Jolly ensures that you can still sweep even if the Sand goes down.
The second set does not necessarily need Sand to work. You could put it on another team and choose another ability, but I don't recommend it. If you go Vital Spirit, anything that would Spore you will be just hit you with a Grass move. If you go Steadfast, anything that would Fake Out you will just hit you with a Fighting move.
