I know about IVs and Natures, however, IVs continue to annoy me because you can't (without memorization) just eyeball a Pokemon and see if it's IVs are good, to the best of my knowledge. You'd need to do some research on the internet to see what a Pokemon's IV ranges are, and how yours stack up.<br/><br/>I guess if I was taking it seriously for competitive play, all I'd need would be the level 1 IVs, since breeding is king, but still.
