Uxie

Uxie has become one of the most prominent Pokemon of the DPP UU metagame, and for good reason. Its massive defenses, combined with its enormous support movepool, which includes (but is certainly not limited to) Stealth Rock, Sunny Day, Rain Dance, Yawn, and U-turn, and high base Speed stat, have made it the quintessential support Pokemon. Not only that, but Uxie is also one of the most dangerous users of Calm Mind in the tier. The only things stopping this knowledgeable sprite from storming the upper tiers are its irritating Psychic typing, which leaves it weak to Pursuit and U-turn; its lackluster offenses, even with the boost provided by Calm Mind; and absence of reliable recovery outside of Rest. Have no fear though; if you're looking for a good lead, supporter, or late-game sweeper, your search has come to an end. Welcome the omniscient pixie into your team with arms wide open.
