ok first of all , as the tittle says, you will need plenty of REGULAR pokeballs (the more the merrier) (NOTE: for every 10 normal pokeballs you buy, you will get a free premier ball) anywaywhen u use a pokeball on a WILD pokemon where it says ''kezza used a pokeball'' or ''Mary used a pokeball'' when that area goes white, hold in the L and R triggers. When the ball 'explodes' release the triggers and HOLD in the A and B buttons at the same time. QWhen it hits the ground and just before the firsts wiggle, release the B button whilst holding in the A button. (NOTE: you may need to use 2 pokeballs for it 2 work.)
