Filling home with go

Gotta catch em all.

I am going for a full living dex of shiny mons. Doing it 95% throught pokemon go.

However the time it takes to be able to send one is just.... the worst.

​

Any idea how i can speed up the progress? I do have acces to another account on pogo and 2 switches.

​

Also no idea how to get shiny mythicals, prefer to grind them myself.

(Wanna avoid getting them from go, since they are once and paid as far as i know?)
