I know I don't have Love Ball stuff, but I might make a point of going back to SS and looking up the various Apricorn Balls. I might be able to come up with some interesting stuff to carry forward. I also occasionally get Apricorn Balls on WT (I wish they showed on Bank, I'll have to import boxes to release 'Mons). So far on Bank I've released Eevee, which aren't in the wild in the first 4.5 generations (only as gifts before, apparently they all visited Kalos before we ever knew about it, those secretive folk :P ), as well as some Fletchling and Bunnelby (native to Kalos).
