If it weren't for the weird plant portals in the preview pages, I'd be speculating that Hickman might bring back the Siege Courageous. I remember he thought it was fun back in AvX – it clearly seemed that he was the one of the team of writers that came up with it – and then he liked it enough to bring it back for Secret Wars.
Mahmud Asrar back on an X-book = all is right in the world.
Asrar's Jean Grey is so...eugh. She gets a big blocky head, and her hair starts to look like Sophie Turners. No thanks.
