Sadly, aggression did not get a very exciting card this time. Forget it completely if you're playing normal: on the first stage it's 3 DMG for 2 resources, 4 DMG on the second stage. You'd better play Piercing Strike at this point.
Downside, it can only target the villain. And also, sadly, you have to be an Avenger to play it, making sure that the one hero who could pull this off nicely by recurring it over and over on 3rd stage - Ms. Marvel - is also the ONLY hero so far unable to play it.
