How do you get more master balls without trading from the elder games?

The only master you can get in the game without trading for more is from silph co...

If you've already used it (on god knows what, let's pray it was the ledgendary dog) it's fine, you were never meant to catch the ledgendary birds with a masterball anyway, they're fairly easy to catch without a masterball.

How you ask? It's simple, how do you usually catch wild pokemon?? just like THAT.

Put them to sleep, poison them, burn them, paralyse them, freeze them, as long as you induce a status change this greatly enhances you chances of catching them.

After that just keep pummeling them until they read red health zone, and then throw your ultra ball at them~ and DONT press any buttons, it won't help, but it WILL decrease your GBA's life span.

There are no cheats to increase catch rate, all you can do is weaken the pokemon and induce a stat change on them... bring a pokemon that knows false swipe along to make the job 10 times easier =D

Good luck and have fun

(by the way, if you used the masterball already, I suggest you get someone to Trade you another one... you need it for the ledgendary dog, unless you have some fast pokemon that knows a sleep move...)

When you throw the ball hold up until the pokemon is inside the ball then hold up and b.

P.S. I was extremely lucky but I caught Moltres with the first ultra ball I used.
