Up + B INKREESEZ TEH CAPTUR RATE!!!!!@!!11111

Hahahahaha! I remember when people used to say stuff like that. I used to tap A real fast just incase it helped the ball stay closed.

The pokeball capture probability is all about chance, so I just threw pokeballs until one worked on the first try (before the Abra could Teleport away) . With those lower level pokemon, I don't think you really need to weaken them much (if at all).
