>>52557475You only really need Salt Cure and Recover. You can go Iron Defense/Body Press if you want a secret setup sweeper, or even Tera Blast if you find yourself having to Tera on waters often. Rocks too of you have the slot, but in that case you might want to go Tera Ghost instead. There's nothing better than turning your rock setter into its own spinblocker (but omit this if you're carrying Gholdengo)
As for EVs/nature, Impish is better most of the time, Relaxed if you're making a Trick Room team. Go full HP and Defense for IVs with the last 4 on SpDef. After that, you might want to do some calculations and adjust some values on the fly depending on what you're doing.
