How to read these recommendations

PvP sets are open-league starting points, not guarantees for every team or matchup. Ranked sets come from PvPoke simulations; unranked Pokémon receive a clearly labeled DexJourney estimate. The raid set is a neutral same-type cycle estimate rather than a boss-specific counter ranking.
