What if there were new apricorns? I was thinking that the next set of games would have a guy named Dave who was Kurt's apprentice (yes this in reference to Dave Grohl and Kurt Cobain), and not only did he learn to make apricorn balls, but he also cross-pollinated some to make new balls, and these were my thoughts:
Grey ApricornarrowStone Ball, which is good for catching Pokemon that need a stone to evolve Silver ApricornarrowMagnet Ball, which is good for catching Steel and Electric type Pokemon Gold Apricornarrow Legend Ball, which is the apricorn version of the Master Ball, but the tree only yields one on the trainer's birthday, and it takes a month to craft.

That legend ball would be pretty easy to exploit in just changing the date on your 3DS.
They'd probably put in a feature that if you change the date, that it won't ever give out fruit, or possibly Dave would say something like "Time got ahead of me and I couldn't finish." meaning that you wouldn't get the Legend Ball.
