Hi there Jake! Thanks, I was hastily waiting for her hatching because I really started to be bothered by the sixth generation so I was hoping I could get this hunt done soon. Glad it was short, once again!
Ahah, I think I predicted right like twice, back when you wanted a Sneasel and just now. Rest of the time was failures.
Oh, I forgot that hunting with a full party meant that the shiny was sent to the PC, and thus was healed there. I completely forgot about that, but don't worry, it's absolutely understandable. When hunting a legendary, you must be really careful, so yeah... Still, that bird was caught, so the battle is history! Oh and believe me, you don't wanna lose a shiny legendary. I'm actually afraid to hunt legendaries for that specific reason without a Master Ball. Though I'm going to risk it with Shaymin without, I believe its catch rate is relatively high (45) for a legendary and has a lot of PP, so I might not need a single Master Ball this time.
Dry Skin Hilton ? Ohoh! I don't think so! I actually use Gallade in X and it works really well; Hypnosis, Thunder Wave, Swords Dance and False Swipe is working like a charm! Otherwise a quick and simple Smeargle can do the trick, especially if you want Super Fang instead.
Rayquaza's moveset is probably the worst; going after it without a Master Ball would be a suicide. Then again, that's the price to pay for such an awesome shiny form, probably one of the best ones, too!
Good luck with your hunts! What are you after, now ?
