first of all, you need a ditto, but the thing is that you should have caught the sons of arceus (dialga or palkia) without a masterball. now give the ditto your masterball to hold. get a Pokemon with the TM thief with it. make ditto and the Pokemon with thief the first two Pokemon. get into a double battle. make the ditto toss the masterball and then make the other Pokemon use thief on the Pokemon which ditto gave the ball to. kill the other Pokemon for fun and then open your bagpack. look in the ball section and you will find 999x masterballs!!!!!!!!!!!!
