It was easy for me, I gave my pokemon really crudy moves and used pp UPS and HP ups, and defence medicine, THEN AFTER ABOUT 2 minutes of using tickle and false swipe, 1 pokeball was all it took. 3 wiggles and ding, he was mine. Easeist legend to catch, but then I accidently turned the game off without saving, so i rebattled him and killed him purposely, then I traded a manaphy to one of my friends to get giritina, nothing done right once he caught it.(I have like 8 pokemon rangers so I don't really care about them)
