Noctowl is weak to Rock (×1.6), Electric (×1.6), Ice (×1.6).
Watch its Flying/Psychic/Ghost moves — counters like Deoxys (Attack) and Deoxys (Normal) take super-effective damage from them.
Rainy weather boosts Electric moves ×1.2 — the best time to battle Noctowl.

Rankings are estimated cycle DPS (attack stat × move damage ÷ cycle time, with STAB and type effectiveness). Not a full battle simulation.
