Currently Masuda Methoding a shiny male Ralts for my OR game. Put out the good feels!
Mewtwo - #150 (Jolly) : 31 / 31 / 4 / 22 / 31 / 31
Not very good Defense, but Mewtwo doesn't really care about it. Besides, he can just use Bulk Up to compensate.
If I were the one to SR for good IV's I would have reset, especially because getting good IV's for legendaries generally does not take that much time with the free 3IVs they provide, especially if you have a one-off Pokemon at your disposal. I've done that for Rayquaza and I got 31/31/31/xx/27/31. I don't intend to disparage you of anything - if it suits you, then I'm fine with it.
SRing for HP Ice on Thundurus is suffering ;-; esp with its low catch rate
Get a master ball. Now. It's gonna take FOREVER if you don't...
But what if he wants to soft reset for more than one thing?
Get more master balls, or just decide what he wants to use one on if he has one, or just continue as he is, I don't know, I'm probably not helpful sorry
Maybe he also wishes to SR for shiny legendaries. =P (Ho-oh and Lugia only have 20 PP to use before they struggle)
