How could eldrazi be reintroduced ?

I'm a big "alien horror" "uncanny looking titan" enjoyer, and the eldrazi just happen to fill that for me on top of being the most satisfying top end a green enjoyer like me could have ( and probably amongst the best green top end period )

And its been a while since we last Saw them in the story. I'm not an OG Magic player, nor do I know exactly how they where received story wise, however...

Should the eldrazi as a concept come back ( so I don't exclude other possibilities, such as something else than emrakul )

How would you like to see them ?

On which plane ?

How should the story approach them, which characters you would like to see involved etc...

So yeah, what's your wish for a potential return of the eldrazi and how would you like to see it play out ?
