As a doubles squad, Whimsicott likely brings Prankster-boosted speed control such as Tailwind or Encore to set up the rest of the team.
Charizard and Basculegion serve as the main offensive threats, hitting hard once tailwind or weather support is active, while Garchomp and Kingambit apply physical pressure and clean up with coverage or priority moves.
Floette adds Fairy-type support and chip damage, rounding out a balanced doubles core built around speed control into a fast sweep.
