Powersaves General?
So I'm building up a premier ball team and apparently Roselia hordes are the rarest damn hordes in the game because psyduck and hoppip are commons. I do however, have access to nest ball HA roselia. If someone's willing to swap one into a premier ball for me, i'd be willing to trade them either a trophy shiny psyduck or a nest ball leaf guard female roselia of their own for their troubles.
