Toxapex must run specially defensive to help support Skarmory and take pressure off of Chansey. This is especially important when dealing with Pheromosa. Buzzwole is just a theorymon on the team because it pairs up very well with Skarmory, Toxapex, and Chansey all at once. Earthquake, Hammer Arm/Brick Break, Bulk Up, or Substitute are all possible options to run over Lunge on Buzzwole; however, each move will change how Buzzwole functions overall. Bulk Up is an interesting idea, but I have not tested it. It looks a bit too gimmicky on paper. Earthquake or Fighting STAB give Buzzwole some absolutely crazy coverage Ice+Ground already cover 9 types for super effective damage, and Ice+Electric cover a large majority of pokemon for at least neutral damage. Roost is mandatory on this type of Buzzwole set for recovery. Skarmory CANNOT hold any item over Shed Shell due to Magnezone existing. Losing Skarmory for nothing in return immediately puts the whole team at a severe disadvantage against most matchups. Buzzwole is the best thing to take knock offs for everything on the team with Sableye-Mega being the alternative option for taking knock offs. Chansey is a very passive pokemon and should not be kept in battle for too long due to the presence of strong physical attackers, taunt users, and dangerous setup sweepers such as Landorus-Therian, Tapu Fini, or Mega Charizard X respectively. Dugtrio is your primary way to get a revenge kill on something that can pose a huge issue, such as Mega Metagross. Groundium Z EQ from Dugtrio is a magic nuke to ward away evil monsters such as Mega Metagross, weakened Ferrothorn, and anything that EQ doesn't 100% OHKO. The magic nuke from Dugtrio can potentially serve as a useful way of breaking through something that benefits from Grassy Terrain, such as Heatran or Magnezone. Counter is another option that Skarmory can use, but isn't as consistent as Brave Bird. Iron Head is technically another option if you find fairy types not named Tapu Koko/Fini to be problematic, but Brave Bird is much stronger and has fewer type resistances than steel.
