I think galuctus will show up at end of phase 4/beggning of phase 5
I don't think doctor.strange could or would do that
Mrriddle0 that would be good in my opinion

While galuctus while may not be a villean he would be a good way to bring all the hero's rogether again a long with this. he galuctus would help explore the backstory between the infinity stones and coiled help bring in or explain the clestials.in guardians of the galaxy you see a celestial destroying a world along with the this ego said he was a celstial.While ego may not be a celestial he mentioned them confirming them in the mcu so how better to explain the backstory of the stones Bring a new bad guy in a new big bad guy in and introduce more characters
Lastly gualctus may not be a villain. But in the eyes of the people of earth who don't know why galuctus is trying to eat planet earth.would you think a person eating your planet is good without knowing a good reason why.
