You gat a master ball after you defeat dreyden in black , or iris in white, professor juniper gives you one , then if you go to the Pokemon center in castelia city , you must talk to the man next to the union room , ( with the black hair and sunglasses) and after you have traded fifty Pokemon he will give you a master ball, he also gives you a choice scarf , a zoom lens , a wide lens , an everstone , and I can't remember what else off the top of my head , but I think those are the two ways, or you can just trade Pokemon who are holding master balls, I hop that helped
