1 way 2 clone a master ball is 2 give it 2 a pokemon (I prefer 2 give it 2 a rare pokemon so that you get 1 more master ball and 1 more of that pokemon) then you trade that pokemon 2 a friend and then after you get out of the trading room then turn off the game without saving then turn the game back on then catch a really low level pokemon that you don't want and trade that low level pokemon 2 your friend and have them turn off the game without saving right after they get out of the trading room (warning! Do not use the GTS for this or you will get banned from ever using the GTS forever! ) and do that as many times as you want so that you and your friend will have more than 1 master ball each!!!! Or you can get a action replay ds from game stop or walmart!
Best way to catch heatran without a master ball
Give the pokemon you r going to clone 2 hold a master ball. .
