I suggested using Uxie and Regigigas both just yesterday when I came back to posting in here again. Nobody said anything regarding it but I thought Regigigas could be awesome choice in the story.
I agree about using the 5th gen legends such as Zekrom and Reshiram because they represent important concepts.
I was going to say what about Jirachi because that was the before list of legends included in the regions but Diancie does work I guess. I still don't like Hoopa lol. Oh well.
I think we should just use some common like Darkrai, Giratina and Celebi but other not very used ones such as Regigigas, Diancie, Xerneas/Yveltal, maybe swords of Justice, thundurus, landorus and tornadus.
If there is an elite four with ghost/dark, am I still the ghost gym leader or am I something else now?
Me and Commander have been discussing my character at length and if things are shifting possibly storywise, then maybe he can do some of what I have requested. What do you think Commander and Jacob?
