Have you decided on what balltism you're going after?

It seems like the apricot and dream/beast balls aren't in just yet sadly. (Probably DLC?)

For the 4 dark legendaries I'm thinking;
Wo-chien - Best would be safari but you can't get, so I'm thinking maybe dusk?
Ting-lu. Level would be best but that's not in too, so luxury 2nd best?
Chien-pao - Obviously dive ball
Chi-yu - I like repeat ball for this, it matches the eyes
