Primarina

Primarina is a fearsome wallbreaker in the UU tier, possessing a high Special Attack stat that is complemented nicely by its fantastic offensive and defensive typing in Water / Fairy. Its typing along with its solid natural special bulk allows it to reliably handle Hydreigon as well as stomach hits from threats like Moltres, Chandelure, and Mega Pidgeot and KO in return. However, Primarina is ultimately held back by its lackluster Defense stat, worsening its one-on-one matchup against common Pokemon like Mega Aerodactyl, Scizor, and Dragon Dance Mega Altaria. Additionally, due to its low Speed stat, Primarina is often forced to take damage in order to get off attacks of its own, ultimately limiting its longevity in combination with its vulnerability to all entry hazards.
