Mega Gengar dominates as top counter for Mega Starmie in Pokémon Go

In Pokémon Go, players face Mega Starmie, a powerful Psychic-type Pokémon. Mega Gengar is identified as the best counter due to its Ghost-type moves, which exploit Mega Starmie's weaknesses. For those lacking Mega Gengar, Mega Sceptile is a strong alternative. Additionally, Dawn Wings Necrozma is recommended as a non-Mega counter, being one of the most powerful Ghost-types in the game.
