Completed my Gold nuzlocke today, finally. One of the harder nuzlockes. It seems that you're underleveled for half the game, so you really can't afford not to grind before any major battle. My team was perfect though - especially Tento who carried my ass against most of the elite 4. Not to mention Sloppo who turned into a tanky dragon slayer with Ice Punch and Nevermeltice. Onwards to Crystal from here!
