Primarina

Primarina is one of the most versatile Pokemon in UU, utilizing its excellent typing, amazing movepool, and solid stats to serve as an integral defensive glue or a potent offensive threat. Water / Fairy is a valuable typing both offensively and defensively, allowing Primarina to answer dangerous threats like Hydreigon, Keldeo, and Salamence while breaking past common walls like Hippowdon and Skarmory. Its RestTalk set counters the likes of Hydreigon and Keldeo, absorbs debilitating status moves from threats like Hippowdon and Swampert, and utilizes its potent STAB combination to threaten the enemy team. Meanwhile, Primarina's three attacks set hones in on its great offensive potential, using coverage moves like Ice Beam and Psychic to overcome foes like Amoonguss and Tentacruel and Substitute to ease prediction by taking advantage of the many switches it forces. This set retains valuable defensive utility against foes like Keldeo, so it is a huge help to bulky offense and balance teams looking for a wallbreaker that can patch up defensive holes. Its Choice Specs set is one of the most difficult wallbreakers to account for, since it has no safe switch-ins apart from Chansey; it tears apart teams relying on Amoonguss and Tangrowth to beat it with its STAB moves and coverage. However, this set does lack the defensive utility of Primarina's other sets, and the three attacks set typically outdoes it as a wallbreaker because it nets the same KOs and has more defensive utility. Primarina's fatal flaw is its Speed, leaving it very vulnerable to getting overwhelmed by faster foes like Thundurus-T, Nihilego, and Zarude that threaten it with super effective damage. Its Defense requires investment so Primarina can check threats like Mamoswine, Cobalion, and Excadrill. RestTalk sets are overly reliant on Rest to heal, meaning they can be taken advantage of if they fail to get the right move when using Sleep Talk. Primarina faces competition from Keldeo as an offensive Water-type due to Keldeo's higher Speed and comparable power, but Primarina's lack of counters outside of Chansey and defensive capabilities let it find a strong place in UU.
