What not to use

Psychic×0Fire×0.5Water×0.5Ice×0.5Ghost×0.5Dark×0.5Steel×0.5

These attacking types are resisted or blocked by the defender's typing, so they are usually lower-priority choices unless they provide a special battle role.

Battle caveats

  • This ranking uses modern Gen 6+ type matchups, STAB value, defensive switch-in safety, and base stats.
  • Abilities, held items, Terastallization, weather, terrain, and format rules can change real battle outcomes.
  • Coverage moves can punish obvious counters, so treat this as type-based guidance rather than a full matchup simulator.
  • Move availability depends on game version and learnset data; this page recommends attacking types rather than guaranteed moves.
