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

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