Uxie

Uxie's position in the metagame stems from the viability of Grassy Terrain hyper offense, which allows it to serve as a consistent sweeper with a Grassy Seed. Thanks to Stored Power and Draining Kiss, it can boost past Steel-types like Togedemaru and Aggron and get past Dark-types like Sneasel and Absol, all of which are common Psychic-type checks. Compared to competition like Swoobat and Comfey, it combines the STAB Stored Power and Toxic Spikes immunity of the former, the latter's ability to hit Dark-types super effectively, and its own formidable initial bulk, which surpasses both of theirs. With that and a solid Speed tier, it is difficult to take down, even with common offensive Pokemon like Charizard and Archeops. However, it is solely found on Grassy Terrain teams, as otherwise, it is too vulnerable to having its setup interrupted before it can sweep. It also can't deal with anti-setup options like Taunt and Encore from Pokemon like Jellicent and Sableye, and it must choose between Substitute and Rest in dealing with moves like Toxic, each of which has its own downsides. It lacks immediate power to force foes out, so even with Grassy Seed, it can be overwhelmed before it becomes a threat. Finally, some wallbreakers, such as Vikavolt and Silvally-Ghost, can use super effective STAB moves break past +1 Uxie with little support.
