So many emerald Nuzlockes, this is getting confusing. @Phadunk, it's a shame about Mach, but I don't think Nina is a massive loss. Ninjask has a terrible movepool and Shedinja is a massive pain in a Nuzlocke. Also, raise that Taillow! It will completely wreck Brawly, and I always find Swellow to be pretty decent in game. (Unless you're not using TMs).
