i caught it with a dusk ball just try and lower it's hp a lot. i recommend you take a lvl 70 and above Pokemon to drain it's hp down to yellow or red, then use a weak lvl 30 to 40 Pokemon to take the rest of it's hp down slowly. once you do that, us dusk ball as they are the best and you should catch it. i used about 6 dusk balls, then i caught it. hope this helps.
