Mesprit

Mesprit is one of the more versatile Pokemon in the RU metagame. With well-rounded stats, a solid offensive movepool, and a good support movepool, it can take on quite a few roles effectively; for example, Mesprit can support its team, sweep, or even break down defensive cores depending on its set. Its ability to check powerful Pokemon such as Slowking, Gallade, and Sigilyph while keeping up offensive pressure is a big key in differentiating itself from the many other Psychic-types in the tier such as Uxie and Slowking. Mesprit also has Levitate, which lets it get a free pass on Spikes, Toxic Spikes, and Ground-type moves, thus making it a better user of U-turn than most other Pokemon in the tier. However, a lack of reliable recovery, a Pursuit weakness, and having only decent Speed leaves Mesprit vulnerable to being worn down or revenge killed by the many offensive Pokemon in the tier. Mesprit's Psychic typing not only leaves it weak to Pursuit, but it also leaves the pixie weak to Bug-type moves from the likes of Galvantula, Durant, and Escavalier. Mesprit's stat distribution, while solid overall, leaves it without a true "standout" stat, meaning that no single set can threaten multiple types of team at the same time. Even so, Mesprit's versatility can give your opponent a headache as they attempt to work out what set it could be running. Mesprit is a versatile Psychic-type and can support its team in multiple ways, so always give it some consideration when building a team.
