Mesprit

With its middling stats in comparison to UU's other Psychic-types, it may appear as if Mesprit has issues standing out from its competitors. Its fellow lake guardian, Uxie, boasts significantly superior bulk, making it far more resilient in a supporting role, whereas Alakazam is significantly stronger and faster, making it appear to be the superior offensive threat. However, it would be foolish to simply write off Mesprit as outclassed, as it has several key perks that differentiate it from these two competitors. Mesprit's higher Special Attack in comparison to Uxie allows it to pressure the opposing team while also providing some of the same support that Uxie would bring, making Mesprit much more suited for teams that want to be aggressive. Moves such as Healing Wish also allow Mesprit to facilitate aggression more easily than Uxie, which seeks to pivot out of dangerous attacks much of the time. Additionally, though Alakazam is stronger and faster, it lacks key coverage moves such as Ice Beam and Thunderbolt, and its lack of bulk means that it can only be used aggressively, whereas Mesprit can pivot into many common Fighting- and Ground-type attacks, providing some much-needed defensive synergy for some teams. Overall, these traits make Mesprit a versatile Pokemon that can fit easily on many teams.
