A simpler question and a more complicated one:
- When I get around to it, Adamant or Jolly Ho-oh? What balls look good?
- How exactly do Dive Balls work in this generation anyway? It says it's "good for Pokemon in the ocean". How would it define "ocean" exactly? Would it count for Lugia since the "arena" shows the same kind of water as surfing on the ocean between Olivine and Cianwood?
I would go with a Jolly Ho-oh, but Adamant wouldn't be bad. And no ball really looks great with Ho-oh, I say just find out which one you like the most or which one has the effect you like the most when you send out Ho-oh and use that one. And I think a Dive Ball gets a higher catch rate when it shows your fight against a wild Pokémon over the water, as opposed to grass or other terrain, so if the Lugia fight is above land, I would say it doesn't get an increased catch rate, if it's above water, I think it will
