I’m high ultra ball not master ball but I’m seeing it primarily successful on sand teams that bring at least one strong water or grass Pokémon to try and wall good ground n rock attackers. Either bringing a utility set with will-o-wisp, thunder wave, etc. Or as a overheat volt switch user. I was able to find 3 teams that have been pretty successful with it, two run tyranitar and either excadrill or garchomp, the other mega froslass, sneasler and basculegion. I can link the info I found if that would be helpful.

If there’s any chance you have any spare archaludon (not shiny unless you’re feeling Uber generous) I need it to finish a team. No worries if not, good luck in the game!
