This looks like a solid deck! Have you considered using Lead from the Front instead of Avengers Assemble!? I made the swap myself and the former is considerably easier to play, while still allowing some other cards to be played. I was a big fan of AA's ability to ready Avengers, but as I played something similar, I noticed a lot of my best Ally cards didn't have the Avengers trait anyway, so I might as well save the two resources.
