This is something that's bothered me for whatever ever reason since I've been able to see the Poke Ball that was used to catch said Pokemon on it's information screen.
I'll elaborate; lets say there's an Elekid and knowing that its final evolution is Electivire, I can see that the Ultra Ball would look most complementary to its design rather than an average Poke Ball. Same story with a Shiny Absol and a Premier Ball. It's one of those things that bother me if I know I could have done something differently.
So my question is; does anyone else relate to the Poke Ball looking complementary to the Pokemon it was used to catch thing, or is it just me?
