You can't do that unless you have emerald. then you can clone the master ball.

You can't always get master balls in any version of Pokemon, or so I've heard. You usually get a master ball once, unless you either clone it or look for it all around the Pokemon world. My advice to whoever wrote this question, don't use the master ball until the time is just right! Okayy... now look over here and not at that useless JUNK! To get masterballs in sapphire and ruby is the " Lucky Number thing " also in silver gold and crystal version you can clone the Pokemon. To clone them look at like " How to clone Pokemon in silver version " or something... anyway and in the Diamond and pearl you can clone too. idk how to obtain masterballs in red blue green and yellow version and idk about platinum too. but this... is all i no.
You cant catch any trainers Pokemon
If the Pokemon Game you are playing is Red or Yellow, then catch Mewtwo with it. If the Pokemon Game you are playing is Crystal, then clone your master ball and catch Suicune, Raikou, Entei, Ho-oh and Lugia.
Lower it HP till it turn red and keep throwing ultra ball at it.
you can't clone in red rescue team
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
