If you don't have enigma stone, keep it for Latios is my advice
use it
you can get 1 master ball
a utra ball or a master ball
master ball
you can use your master ball
to capture the legendary Pokemon you meet
Use a master ball
capture legendary Pokemon like rayquaza.
Once you have 8 bages, you talk to pofessor Elm and he will give you a master ball.
no the master ball works strait away without doing anything to the Pokemon
no, you don't have to use your master ball on it. you could use it for any legendary Pokemon like mewtwo, or... you know what i mean!
depends on Pokemon
