MONO BUG

by Here Comes Team Charm

Vivillon kills nearly everything below 304 speed by spamming pseudo-Spore and substitute. Also beats Rock Blast Crustle (sleep powder, attack twice) and Mega Venusaur. Notably beats things like Magnezone and Magearna pretty reliably. Crustle is crazy solid versus most of the things that outspeed Vivillon, like Greninja, Victini, the Zards, Porygon-Z, and Tapu Lele. It also beats nearly all dragonites with Counter and/or a +2 Z-move. Volcarona is there to beat Mega Mawile, Metagross, and Gardevoir, as well as Registeel, Aegislash, stall Mew, and Whimsicott. It also beats Garchomp: EVs are to tank a rock tomb/tectonic rage/band outrage and KO with Swarmed Z-Bug Buzz). The team has a few problematic matchups like Rock Blast Golem, scarf special Dragonite, and Overcoat Kommo-O, but those tend to be rare.
