you're going to get a starter, and it's going to mean a lot to you.
but throughout the game, you're going to run into plenty of other pokemon.
some, you'll use a pokeball to catch. others, a great ball, or even an ultra ball.
you're going to run into a couple rare pokemon and even a few legendaries.
but no matter what you do, save your master ball.
save your master ball for that one pokemon...
that one pokemon that is truly legendary.
