>>54184629Don't do this, this is one major turn off people have with fangames, all types having gyms and gym leaders having a legendary/mythical, fusion pokemon is already well over done in the fangame community. If you want a gimmick, make it your own.
Choose 8 types for gyms and 4 types for Elite 4 members, it makes the region and characters more unique, try do what Kanto/Johto did and make the unused types in Kalos the types for the gyms here, so that leaves Fire, Water, Flying, Normal, Poison, Ground, Ghost, Dragon, Dark and Steel - A lot of these types don't have many gyms in the mainline games i.e Ground and Poison, so make use of that.
