Some people say that when you hold A, B, SEL together, it is like a master ball (when being thrown). Some people say they are liars.

But I know the truth! :NOTE: Can only be used on legendarys.

Ok, when fighting legendaries, ever find it hard? That ends here! When fighting legendaries, their health is low, and they have a status problem, (sleep poison etc...) throw an ultraball and before it leaves ur hand, hold A,B,SEL together. And before it opens 2 catch whatever pokemon ur trying 2 catch, take ur finger off A. it works 80% of the time.
