Once you beat the eighth gym, go outside of the gym then,then after that go to castelia city and trade with 50 people around the world then talk to a man on top of the stairs from the Pokemon center and he will give you a master ball hope this helps!!! :)
Or you get one from Professor Jupiter after getting the 8th bradge.
the master ball is for zekrom in white and reshiram in black
you can trade a Pokemon from black or white holding a master ball.
professor juniper gives it to you
In white you use the master ball in black you trade
Yes, you can get a master ball in Pokemon black. You get the master ball towards your last gym battle from Prof. Juniper =)
Definitely Thundurus. You can get 2 Master Balls in Black and White. You should save the second one for shinies or event pokemon.
you can get one from trading from someone else a pokemon that is HOLDING a master ball, or you can use cheats
From the professer in main story at plane town
to get a 2nd master ball trade with 50 diffrent people and go see a man in black in the castela pokemon center
