Espeon

When talking about Espeon, the thing that immediately comes to mind is its fantastic ability Magic Bounce, which bounces back status moves, particularly Taunt, Swagger, and most phazing moves. However, Magic Bounce is not the only reason to use Espeon, as it has a good Speed stat that enables it to outspeed common threats like Garchomp and Mega Kangaskhan and Speed tie with Gengar. Espeon also has a good offensive movepool with moves such as Stored Power, Dazzling Gleam, Shadow Ball, and Grass Knot, alongside a great Special Attack stat that aids in sweeps, and a handy defensive movepool, having access to Calm Mind, Yawn, dual screens, and a recovery move in its signature Morning Sun. With the combination of these tools, Espeon carves itself a niche in the Battle Spot Singles metagame as a Calm Mind sweeper, a fast dual screen user, or simply one of the best Baton Pass recipients in the game. What really keeps Espeon from being more than a niche Pokemon, though, is its lacking physical Defense and HP stats, leaving it vulnerable to many common physical attackers, such as Mega Salamence, Mega Mawile, and Talonflame, and Sucker Punch users due to its Psychic typing. Even on the special side, it is weak against common threats like Aegislash and Greninja that can easily take care of it. Because of its frailness, Espeon greatly suffers competition for a slot on the team from bulkier Calm Mind sweepers such as Mega Sableye, Suicune, and Raikou, and from dual screen users like Klefki, which has Prankster and a better defensive typing.
