Sentient Movepool Trivia
Please keep in mind that apricorn balls have been programmed into the previous two generations despite being inaccessible. It's likely just there to preserve HGSS Pokeball Pokemon having the right ball. I'm pretty sure you can do the same thing this person did with HGSS / Dream / Cherish balls in XYORAS.
What tent are you referring to? Do you have an image or other source you can share for clarification.there is a Johto Tent in SM I know. So we can only hope the tent can make Apricorn Balls or something lol
