Time travel's been done so many times...
Urza's Saga,
Time Spiral (
duh), Tarkir, but there's nothing stopping them from doing it again.
Obviously at least a couple members of the gatewatch will be front and center. at the end of the war of the spark novel they gave different groups of two or three watchers the tasks of hunting down
Dovin Baan, Tezzeret, and Liliana. So I think that will take up the next few sets. I just hope it's somewhere new. Perhaps we'll finally get an actual legion of doom, with dovin, tez, and lili recruiting people like ob nix or some of the other "evil" planeswalkers" or something. Magic: the Gathering: Civil War.
I just want more Davriel. and to know who the hell
the wanderer is.
Anyway, that's still a ways off. Next thing to hit spoiler season is C20, and then the next standard set to
release in Sept. Can't wait for C20 though, as a huge EDH lover. I only follow standard for the story.
