Feels too rare for the player. Understands not wanting players to ignore the catching mechanic. Ought to be available in post-game for a high price, though. Developed these as early as Generation 1. Advanced technologically in the Pokemon world since then, much like the real world. How have their Pokeballs not improved? Expects standard Pokeballs to be like a 1 gigabyte hard drive today.
Saw Master Balls from Kieran and Sada/Turo in Scarlet/Violet too. Clearly acquired them somehow.
