I completed a Hoenn Living Dex in RSE by getting every Pokémon in their most difficult way possible!

This living dex contains the most difficult way to obtain each Pokémon, that means catching every single 1% encounter, Mirage Island Wynaut, no breeding for easier access to starters, fossils and Beldum, and also every swarm Pokémon obtained in no native games via record mixing.
