I was hoping I'd find a fighting type in Mt. Moon or Route 4, but no luck>>18473358Under the options in game you can change it from Shift to Set. Basically it doesn't give you the option to switch out your Pokemon when an opponent is switching his Pokemon.
Additional rules are all optional, you can customize the Nuzlocke to your liking by adding/removing or making new rules. It's all about self-imposed challenge.
