Core Team Roles
Sweepers, walls, pivots — what each Pokémon on a 6-mon team is actually doing.
The Five Roles
Sweeper (fast attacker that snowballs after a KO), Wall (high HP/Def, stalls), Pivot (switches in safely, U-turns out), Lead (sets up the field early), Cleaner (mops up at the end). A balanced team has 2 sweepers, 1 wall, 1 pivot, 1 lead, and 1 flexible slot.
