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?
Lure Balls! They're such a fun design and such a specific use, they're super satisfying to use. It helps that most of my favorite Pokemon are fish
Given my undying love for the bug type you'd think I'd have used more net balls in my Pokémon journey, but uh... Nope. I don't think I've ever tossed a single net ball, ever. I should look into that.
