I heard that if you give a ditto and another pokemon each a masterball and breed them the hatchling will be holding a masterball?!? Is it true?
That is not true. There is no way to do it without AR.
Well, you could breed. If you give the female the master ball to hold, the baby Pokemon might have another master ball, but I believe it is a very low chance of the egg to have one when hatched.
