[@Dynamo Frokane] About your post, you need an official Pokedex given to you by a Professor to challenge Gyms in most if not all regions. That's been set in stone in the Anime I'm pretty sure. I could accept that the Pokedex Model you put in your post was the one you were given, but one would have expected you to have at least the Sinnoh Dex since you came from Sinnoh and such.
