You’re a mind reader; I toyed w. both Black Adam and Zod as Sentry!
I settled on Bats as Cap, despite how many Bat-fam members I’d wind up with, because Bats and Cap have that leadership prestige Bendis’ team needed/my team would need.
GL as Iron Man’s not perfect, but I wanted another normal guy underneath the mask, not an alien/Amazon/Atlantean...
I went w. Nightwing as Spidey for recognizability and the fact that it let me use Batwoman.
Black Lightning as Cage seemed right, as both started as 70s neighborhood protectors and been fan favorites since, if not critical successes.
Slade as Wolvie fit for me in terms of them both being around (in canon) forever, knowing/having fought everyone, having hardcore reps, and business wise they guest star in multiple books a year on the regular to boost sales.
Settled on edgy hood up Captain Marvel as (the Superman level character) Sentry to add a splash of color tbh, as my team mostly have dark outfits!
Glad you liked it.
