Mesprit

Mesprit is a highly flexible Pokemon that is capable of fulfulling a multitude of roles within the ZU metagame. Its balanced stats and useful movepool allow Mesprit to work well in offensive and defensive utility roles, while its Nasty Plot set is a threatening sweeper that is extremely challenging for bulky builds to deal with. Mesprit is also a good check to Fighting-types such as Virizion and Passimian, and Levitate lets it deal with many Ground-types, such as Sandslash and Sandaconda. Unfortunately, Mesprit's balanced stats means that it isn't truly exceptional at any role that it tries to play, as its offensive stats aren't fantastic, and bulky sets are prone to getting chipped down over time. Its Psychic typing also leaves it vulnerable to common Dark-types, such as Sneasel, Spiritomb, and Persian-Alola, while also leaving it weak to the ubiquitous U-turn. Finally, Mesprit's coverage is quite limited, as it lacks a way to hit Steel-types hard and doesn't hit much of the metagame for super effective damage. This can lead to it sometimes struggling to break through bulky threats such as Articuno and Snorlax.
