Use A Master Ball Or Ultra Ball To Catch. But I Think It is Hard To Find Master Ball...:/
You cannot find a second master ball however you can trade Pokemon to get another Pokemon with a master ball or use an action replay
theres only 1.
The only way to get a Master Ball is to win in the Pokémon Lottery Corner, by storing a Pokémon with a trainer ID with 4 or more numbers that match to the last numbers in the number you are given by Felicity. And no, there is no place you can "find" a Master Ball. -M_C
The only way to get another master ball in Pokemon dimond whithout cheating is by giving a Pokemon a master ball as an item in another game and trading that Pokemon to your Pokemon dimond game and take the master ball then you can use it. Or you can get an action replay at www.amizon.com for $20.00 and find the master ball cheat for it then you can get lots of master balls all the time it realy works try it.
you must win 1st prize in the lottery.
Mewtwo is in Cerulean cave.i recomend you save your master ball for this and also take a couple of max repels
Fly TO Lilicove city and Surf ontop and you will find a cave,go inside and find the master ball
yes. once you have beaten the game go to your home city and travel around the whole map. there is a master ball you can find in the grass on any side of the map. its different for everyone. also, it may be in the water or on rocks. look carefully. because I once battled a master ball. the way you get to battle one is to catch every single Pokemon in the game and then realease your pikachu.Satoshi Tajiri,Pokemon creator
