After extensive testing, came up with this team. I like juice Vullaby, but eviolite+roost can help against grookey. also abra is good for not losing to setup, specifically scraggy (who is stupid good rn). finally, you should almost always lead either mienfoo or nidoran; shellder on the rare occasion.
