I have to completely disagree with Mesprit being better than Uxie. The bulk and Speed are so important. I know that a few people, including myself, are running an offensive Uxie lead with the same set as a lot of lead Mesprit (Grass Knot / Psychic / Thunder Wave / Stealth Rock) and it has performed better than Mesprit using the same set. The ability to outspeed and 2HKO Qwilfish before it can explode or Spike again is vital. Uxie still maintains the OHKOes or 2HKOes against Rhyperior, Kabutops, Omastar, Cloyster, etc. The ability to revenge kill Venusaur is also pretty great. That is just including that lead set; dual screen Uxie, Sub CM Uxie, regular support lead Uxie, Scarf Trick Uxie, etc. are still more reliable at their job than Mesprit would be.
