What Pokemon do I not need in order to get the shiny charm in sun/moon?

Question

I'm trying to Complete my 'Dex to get the shiny charm, with some help from the GTS.

I can get Magearna By Finding the QR code online (But I'll upvote any answers that show the QR code).
Then I realised that Marshadow is unreleased. Pls give a complete list of Pokemon that are not nessacary to complete the Pokedex (not including Pokemon not in the regional dex, but including forms.)

Answer 1

Here is a list of all the Pokemon you will need to catch: LINK
As you can see if you scroll down, Marshadow is not needed to complete the Dex, but Magearna is needed so you can find the QR code here.
