At the Marvel: Next Big Thing panel at Wondercon, comic book writer/artist Rick Remender mentioned that what he'd like to write is a book that gathers various Marvel mystic characters and write them as a team. A Marvel version of DC's Trenchcoat Brigade and/or Justice League Dark.
Doctor Strange, Scarlet Witch, Juggernaut, H+Damon Hellstrom, Iron Fist, Ilyana, Valkyrie… you could see how this could go…
Would you pick up such a book? And with Rick's importance to Marvel right now, could they deny him?
They do have plans for Doctor Strange after all- as was reiterated on the panel.
