Decided to go with 3 attacks + Knock Off because it's a cool tech that allows you to punish standard switch-ins, such as Celesteela or Slowking. I decided to really double down on punishing fat with Scarf+Toxic Keldeo, which really butchers AV Tangrowth/Slowking builds, while also keeping the offense matchup decent. Skarmory is the knock answer, while also handling threats like Krookodile and Scizor. Spikes, however, are the main reason for Skarmory being here, since I have 3 Knock users, Spikes are sure to be effective. I decided to try a tech with my fourth slot, being Bulk Up last rocks Krook. Bulk Up + Chople allows you to punish standard stuff like non-whirlwind Skarmory, Bulk Up Zeraora, Terrakion, and so on, by boosting out of KO range, and making Krookodile actually a threat. Still does Rocks Krook things, and Taunt is easily slappable in the fourth slot if you find yourself not liking Bulk Up. Last 2 slots are the rest of the backbone, as Tentacruel+Tangrowth handles a bunch of other threats, such as Azumarill. Only major issues this build has is Kommo-o, which is stupid mon anyways, mixed Victini, which is broken, and doesn't do particularly well vs unmon Mimikyu HO's. Also offensive Salamence 6-0s defensively.
