How do you get more than one Master Ball?

All you have to do is win the lottery at the Jubilife TV station and you will recieve another Master Ball. To win the lottery one of your pokemon's I.D. Number has to match exactly with the number you draw. This is very unlikely so your best chance is to trade for Pokemon with as many people as possible to increase your chances of winning another Master Ball.

Goo goo g'joob

Yes but you have to migrate from another game in the other game you give the Pokemon the masterball and when you migrate it take the item away from it

Also I got a master ball from the glactic grunt boss after I beat him in veil stone after I got the icicle badge.

|*sigh*|
I just answered this same question but except masterballs it was rare candies...

1) give item 2 Pokemon you don't care about

2) use the 'emerald cloning glitch' on that Pokemon 7 or 8 times

3) migrate 6 of that Pokemon holding that item to you're ds game

4) catch that Pokemon in the pal park...and it will be holding the item you gave it

Be happy w/ you're 6 masterballs a day...

1. Win at the Jublife TV or migrate Pokemon from other games holding a Masterball.

2. At an Event.

You can also... if you have another pokemon game, use recycle after you use the master ball you got trading from the other game and bam! you have another master ball.

i need another master ball without another pokemon game
