>>50474685A short-gap lazy placeholder. ILCA probably didn't want to code PLA's balls and make sure they get inherited properly. In PLA's side of the equation, GF didn't want to code all the other balls that don't appear because it's the "past" and they don't exist. SwSh is like a middle ground, they don't have a Strange Ball nor they need to as they leave them instead into normal Pokeballs. ILCA could have done the same but I guess they wanted the Strange Ball to be everlasting proof of the "link" between Hisui and Sinnoh
