Have a friend trade you a Pokemon holding the master ball they received.
there are two ways you can get a second master ball is to trade someone a Pokemon holding a masterball or by hakingIt is impossible unless you want to hack. Google search for "gameshark".
No. You can only get one master ball. But you can get one from a friend or if you have a GBA game like emerald, leafgreen, ruby like those and have a master ball on your GBA save make a Pokemon hold it then in pearl or diamond go to Pal Park and choose the Pokemon with the master ball and 5 others from your box capture all of the Pokemon then you will have theMaster Ball
You can get only one Master Ball in LeafGreen (as in every Pokemon Game) in the Silph Co. by Giovanni. Another way to get more Master Balls in LeafGreen, is to hack your game using Action Replay (if your game is in a Game Console, because there's another way of hacking Pokemon games if they are in your computer). Hope I helped :)
buy them at walmart
You don't. The only one you get is from the Silph. Co. President after you beat Giovanni in Saffron City. There aren't any more.
there is only one master ball in leaf green, so should save it for mew and the 3 lgendary dogs
no
The only way to get an additional Master Ball in Pokémon XD is via trading with 1 of the Gameboy Advanced Pokémon games such as Ruby, Sapphire, FireRed, LeafGreen or Emerald.
In Pokemon Diamond, Pearl and Platinum you can get one master ball from Master Cyrus. To get more, you have to cheat using a Action Replay DS or DSI, or you can trade Pokemon with your friends and receive master balls from the Pokemon that they traded.
give one to a Pokemon and trade the Pokemon with the master ball.
You trade Pokemon from friends that's Pokemon is holding a master ball
Nah you can just get 1 Master Ball in a game... if u want more.... jus place the master ball in a Pokemon and trade it... after tht start the game all over and get another master ball :P
