Notes
All these pokemon require you to complete the things with girantina. All are LV50 and psychic Mesprit
Mesprit is at lake Verity. When you go to the cave in the middle and press A against Mesprit, it will fly away. It will roam around Sinnoh and you can track it with the marking map. Azelf
Azelf is at lake valor. It will be a normal battle. Tips: Bring lots of dusk, ultra, and timer balls. Azelf won't go to sleep if it used uproar till the uproar ended. High stats in attack and Spe. attack. Uxie
Uxie is just like Azelf but at lake Acuity. Has high stats in both defenses
