Mine are the Hisuian balls, specifically the Hisuian ultra ball. I just love the design of the latch, and the color palette used for all the balls. I especially enjoy the little flourish on the yellow stripes of the ultra ball!
What's your favorite? Any particular reasons why?
... Huh. So it is. Legends: Arceus was my first interaction with a Heavy Ball, and in those games it gets a bonus to capture any Pokémon that hasn't noticed the player. How odd.
I also totally understand where you're coming from. If I was a more patient person, I'd probably be the same. I am, unfortunately, not that disciplined. 😅
