Only 3? Oh! I thought it was thirty. Thanks, that should help. The only problem is that I don't have anything other than quick balls, repeat balls, a couple pokeballs, a couple luxury balls, and several timer balls. I can't believe Darkrai has a catch rate of 30. Oh well. I just hope that when I find a shiny, it'll go into a quick ball easy enough, or I'll have to wait it out with paralysis and hope for a timer ball capture.
 I'm now trying to catch it for good nature, I don't care if it's shiny. I'll check for relative IV's as well. First catch: Pokeball.
