I know that everyone has already pretty much come to the conclusion that that list is fake but you can easily prove that it is anyway. Ever since Gen V(?) the Pokedex has gone in order of where you find them in the game. We already know that the second island is Akala, the pink island, so the Psychic Tapu should have been before the Fire one in the Dex. Then on top of that, there is stuff like Bewear, which is never going to be that early in the Dex, and stuff like Lurantis, which we already know is found in the Lush Jungle on Akala Island being way to late in the dex. So basically, that list is fake as fuck.
