Well, if we're talking balltism, I'm deciding on which ball is best for Palkia.Since it's the Spatial Pokemon, I am debating between.
>Dusk Ball for night sky (Space)
>Moon Ball for night sky (Space)
>Dive Ball for "the ocean is kind of like space, you guys" which is why Palkia is a Water type to begin with
You can only catch so many pink Pokemon in Heal balls before you need to mix it up beyond color, you guys. Also, I don't have the Love Ball, but I can catch a shiny Palkia with that on a dynamax adventure.
