Well, there isn't really an obvious answer to your question. The only thing you can do is hope you catch it with something else, such as an ultra ball. I suggest if you don't have a master ball use either a quick ball or an ultra ball.
Hope I helped!
Use an Ultra Ball, not a Master Ball
i recommend using a master ball or a Heall Ball Hoped I helped!!
Either weakening its HP or using a Master ball, but i recommend you use a master ball.
don't capture Gratiana with the master ball that you get from team galactic leader instead keep the master ball and go to see heatran after Pokemon league and use master ball on heatran and catch him instantly
you should use it on lugia. he is the hardest one to catch. you cant catch him with any other pokeball. you can only catch him with a master ball.
After you go to burned tower it will appear in the wild randomly. how you catch it is up to you (personally I would use a master ball)
Any pokéball
no
I'm not quite sure what your talking about, but I would have to say that you would not have to catch it in a Master Ball.
Yes
you need to have two master balls.
yes, i caught suicine with a friend ball!
Use an Ultra Ball, not a Master Ball
Of course, a Master Ball catches any Pokemon without fail, Legendary or not.
This is impossible without the use of cheat codes, unfortunately. Only the Master Ball can catch Pokemon without fail.
not without a gameshark
You use a master ball
