Starmie

Starmie is a prominent offensive Pokemon as a result of its good movepool, Analytic, ability to outspeed Latios and Keldeo, and decent defensive typing, which lets it pivot into Fire- and Water-types like Heatran and Keldeo. These traits make Starmie fit well on hyper offense teams as a strong Rapid Spin user and on rain teams as a devastatingly strong wallbreaker. However, Starmie can struggle to break through common Pokemon that resist its STAB moves and aren't weak to its coverage, namely Ferrothorn, as well as others like Rotom-W and Gastrodon, while offensive Pokemon like Latios and Kyurem-B can take at least one hit from Starmie and OHKO it. Starmie is also quite frail and easily worn down by entry hazards, Life Orb recoil, and sand, making its longevity and ability to switch-in limited despite its typing. Further, Choice Scarf users and Alakazam outspeed Starmie and threaten it with super effective coverage, with Choice Scarf Tyranitar and Scizor even being able to Pursuit trap it. Starmie also faces competition as a fast Water-type attacker from Keldeo, which has more set versatility, can threaten Ferrothorn, and has a better defensive typing.
