Got my butt handed to me by Lucian of the E4. Caught Uxie, going after Azelf and Mesperit next.
Checked the IVs of Uxie and my Palkia
Palkia: 21, 7, 13, 7, 10, 30 (50% acc. 33% acc on hp and sdef) Naughty
Uxie: 24, 6, 18, 20, 30, 16 (50% accuracy) Serious.
This according to Serebii's DP Iv calculator.
