Another hazard stacking core this time focusing around Calm Mind Tapu Koko and Victini setting up for the former in becoming an amazing wincondition. Hippowdon and Skarmory are amazing defensive core as well as hazard setters for these type of teams with Sand Strom making chip a lot easier to wear down stuff, and Hippowdon is even running Whirlwind to phase out set up attackers notably Volcarona and Clefable. Skarmory is running speed here lets it be faster than max Speed Magnezone can be helpful in hitting hard back after a boost and even picking it off on the switch. Scarf Tapu Fini fitted nice here since it help in dealing with Urshifu-R, Volcarona, and Weavile gave the team a lot better speed control in handling with Dragapult and friends. Defog seems redundant here cause of hazard stack, but it helps with Hippodown and Tapu Fini from getting overwhelmed by opposing hazard stack teams, and really would be click when you know you need to. Weavile concludes the team another great wincondition with spikes, and does Weavile things pretty self explanatory.
