Simply put, you cannot. The "Select-A-B" combination among other things are just superstition and do not really work.

MasterBall
I would use a Masterball or a Nestball or a Ultraball. Hope it helps! ~Camille
masterball :) if not try use sleep and have at lowest energy and use fast ball or ultraball
A masterball would be the best choice but if you want to save it, you should use a Pokemon that does not let him flee (he always flees after the first turn) and use regular pokeballs or ultra balls
To make any normal Pokeball (not Great or Ultra Ball, just your normal, average, everday Pokeball) a Master Ball, do this: when you throw the ball, hold down A and B, but from the time that the Pokemon goes into the ball to the time that it hits the ground, hold B and Select. Works nearly all the time if you have perfect timing. I caught kyoger and rayquaza with it!
