Well dang. Thanks for the answer though :)Same species only. Same egg group or evolutionary line doesn't work according to eworm's testing. So no Jangmo-o won't pass the ball.
As long as you can catch a wild axew in alola then yes moon ball axew is legal. So far there is no known method of purchasing apricorn balls.
Now, I am looking for a Male Smeargle with Psychic terrain for my uranguru. Don't want to wait till post game, since i want to use the monkey on my first team and feel bad replacing it for a baby after going through everything.
I can offer any natured abra, HA timid vulpix's with Extrasensory, freeze dry, and Moonblast, and Adamant Stamina Mudbrays with close combat.
