The first four issues chronicle an attempt by the newly-reformed Masters of Evil to take over the Avengers flying city. The last two deal with the search for the "Missing Moment" and the anti-climactic reveal of who exactly Myrddin is (saw that from miles away). There's nothing connecting the two, just a sudden, jarring shift from one story to the next. The Masters seem particularly inept this time, never a real threat at all, even for Captain America, who's feeling sorry for himself since he's not a superhuman and has been injured in the fight against Doctor Doom. It also doesn't help that there are 3 very different, very distinct artists at work through these 6 issues. It's really not a terrible collection, just not especially well tied together. I'll echo another critique--I, too, think maybe MacKay is better off focusing on individual characters rather than writing a team book.
