Now that shiny Eternatus is out, is there a way to legitimately register the shiny Eternamax on the SwSh dex or is that only possible by editing your save using PKHeX?
I tried using Eternabeam, but that also doesn't work.
I'm trying to make an event Mewtwo for LGPE but it keeps saying it doesn't exist a Mystery Gift data for it during the legality check.
Is it possible to add it on the PKHeX database?
