Primarina is weak to Poison (×1.6), Grass (×1.6), Electric (×1.6).
Watch its Fairy/Water/Psychic moves — counters like Sceptile (Mega) and Beedrill (Mega) take super-effective damage from them.
Rainy weather boosts Electric moves ×1.2 — the best time to battle Primarina.

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