I've used this team a bit, it's pretty solid. Spdef allows marowak to live longer (and tank one surf from tapu fini)
SM physical minior, ev spread ensure that necrozma's psychic bring you below 50% after shell smash and you are immune to para before shield Down.
Scarfed rapid spin tsareena, because grass and fighting coverage is great. Hope you like it bud
