One question, Mesprit's Nature is set when you meet him for the very first time, no??
So the best to get a good Natured one is Saving before meeting and then look for him at the Map, catching it with a Master Ball (Got Emerald to clone them), if has the desired Nature and Stats, save, and if not then Reset.
I'm pretty sure about this but i would like confirmation :$
