Nevermind. I figured out where the Pokemon League/Victory Road is.
But that's not important now. How do I catch the Mesprit? I understand the whole following it with my one Poketch application (stupid name for a Pokemon Watch, btw), but once in battle, it just seems to run away from all of my pokemon.
I recall reading that the move "Mean Look" will keep it there, but none of my Pokemon are fast enough to use it.
Also, was it a mistake to use my Master Ball on Palkia (and my fiancee used hers on Dialga). We kind of figured that since they were on the box, they were the equivalent to the Mewtwo of the game (making the three lake pokemon kind of like the three legendary birds from the first game).
Any general strategies on catching Mesprit, Azlef, and Uxie?
