"Pokémon Sun/Moon Retrospect: Who's worth your Master Ball?"

I've finally decided to take a weekend and play through the rest of Pokémon Sun before I go pick up Ultra Sun or Ultra Moon. I just received the master ball and wanted to figure out who to use the ball on. After a little bit of research, I think I've decided which Pokémon I will use it on.But what about you? Looking back (assuming you've beaten the game, even if you haven't), who would you throw the master ball at? via /r/pokemon http://ift.tt/2AHn8dF
