On September 9, we return to where it all began for Magic's 30th anniversary—and the first act of a legendary story.

It's near the end when it takes about Wizard's Presents, which is big, big announcement thing August 18th, the same day Dominaria United finishes it's story.
They even have art for the event with Drizzt, Boo, and a Beholder on one side and Jaya Ballard, Elish Norn, and Ajani on the other.
I think they could finally be merging the multiverses, fingers crossed. I think it could be tied to time travel shangegians like the original mending.
I'm also expecting an Honor Among Thieves set.
