Oh gosh, you're asking me to list a lot haha.
Shinies I have: Clefable, Wigglytuff, Azumarill, Granbull, Gardevoir, Mawile, Togekiss, Whimsicott, Florges, Aromatisse, Slurpuff, Dedenne, Carbink, Sylveon, Klefki, Galarian Weezing.
Shinies I need: Alolan Ninetales, Galarian Rapidash, Mr. Mime, Primarina, Ribombee, Shinnotic, Comfey, Mimikyu, G-Max Hatterene, G-Max Grimmsnarl, G-Max Alcremie
And I guess I need the Tapu's, Diance, Magearna, Zacian, Zamazenta, and Xerneas too but they're shiny locked iirc. Most of these are still unreleased in SWSH though.
I'm also not counting shiny Arceus or Silvally -- but I do have shiny Swablu and Audino in case Mega Evolution comes back! :D
