Ive been using this uxie set since the very dawn of RU, and despite the weird look, i personally think its the best uxie set ive ever used.
Uxie @ Lum Berry
EVs: 252 SAtk / 252 Spd
- Stealth Rock
- Thunder Wave / Giga Drain
Offensive Lum Berry can be a thorn in the side of many teams in the RU tier. Despite only having base 75 special attack, Uxie's Psychic still hits decently hard, enough to KO frailer opponents trying to set up on it or wear down a big threat to your team. Even without any defensive investment Uxie is still very very
bulky, and your opponent will find the pixie nearly impossible to OHKO (seriously, ive had this live Accelgor Bug Buzzes and Absol Night Slashes >_>). With a combination of this monster bulk and base 95 speed, Uxie will have no trouble setting up Stealth Rock and paralyzing multiple pokemon on the opposing team before it goes down. With max special attack Uxie can also utilize Giga Drain to OHKO Kabutops, and thus protect its Stealth Rock, i prefer Thunder Wave though. Uxie's Lum berry can really come in handy against other leads, it guarentees Smeargle will only get Stealth Rock up at most, as Psychic will 2HKO the painter before it can accomplish much of anything. It also does 40%+ to Aerodactyl, so Uxie isnt a sitting duck against the other common leads (pineco is a meanie :( ). Overall, despite the reduced bulk making a difference in some situations (vs nidoqueen, you will do 80% at most if you switch into Sludge Wave, still good enough for me though). I feel this is one of the best sets Uxie can run in this metagame, and i urge all of you to try it out!
Another set that hasnt been mentioned is the Dual Screens set, Uxie is perhaps the best setter of them in the tier, and shouldnt be overlooked. The set looks a little like this.
Uxie @ Light Clay
EVs: 252 HP / 4 Def / 252 Spd
- Stealth Rock
- Light Screen
- Memento / U-turn
This set is an excellent option for all kinds of offensive teams, it can come in on a variety of threats, set a screen or two, possibly get Stealth Rock up, and either Memento to provide your Pokemon with an even easier setup, or use U-turn to keep itself alive to set up screens later in the match. Once again, Uxie's base 95 speed comes in handy here, giving Uxie a chance to set up a screen before the opponent can even hit them, thus giving Uxie more time to set up the second screen! Overall, these are my two favorite uxie sets, and feel free to post your thoughts on them!
