I'm at the last battle, and I am stuck. I have two questions, what nature should lugia be, and should I waste my masterball on it? I want the masterball to catch mewtwo in heartgold, but lugia is a pain to catch. He takes like 50 balls to catch each time, and though I have enough to catch his other six, I just hate resetting just to get a crappy nature. Now I've done this twice before, one a quirky nature (didn't know better) and a careful nature. Now I know better and what should I do?
