i belive bendis goal is to refresh his rosters and thereby making at least half of every avengers team - skrulls.

new avengers
strange = his lame magics on the series are all skrully
theAVENGER wolverine is one, he can't possibly be everywhere, the x-men one is another skrull
echo - a skrull sent by elektra
hawkeye - no bow? realy???
iron fist - he realy isn't impressing on the team
the only one who isn't a skrull is cage!

in MA
i'm not sure who is ar isn't a skrull there BUT spider woman IS a skrull
and she gave the elktra body to iron man to trow suspicion
