Variant covers these days have nothing to do with the story. The Avengers group you mentioned is New Avengers, with one character holding an AIM card reading "Avengers Idea Mechanics"... I'm also not sure Squirrel Girl is on that team. Most of their team books had me going 'WTF?!?' to half their rosters. I also think books like A Force is Marvel trying a little too hard to get more female readers. An Avengers book about all male characters would've been called sexist by fans and reviewers alike, all women though? That's progression... lmao ~KL~
