Invalid About Set Up A New Format

[QianJiang-China]

I want to apply for the development of a new format：National Dex Doubles OU/Uber.Since many of my friends considered that National Dex is only available in singles format.And it will be very interesting to try to blend Gen8's Pokémon with Gen7's mega and Z.I hope that you can take my advice.If the format is set up,I
will be willing to help.
