I am thinking of including some combination of these two cards in my T-Bolts/Avengers deck. The deck is mostly T-Bolts, with a smattering of Avengers mostly for Justice For All & Rick Jones. For thematic reasons, I don't use Citizen V (either drop) so I don't have a ton of exhaustion in the deck, other than blizzard. I do run Hawkeye however and, with the general amount of curve jumping involved in T-Bolts, I figured No Fear may even allow me to do it with guaranteed safety of a non-stunback.

Basically, I was wondering if anyone had any thoughts or suggestions on this.

I don't think there's enough exhaustion at all to try Crushing Blow. If you really want +3/+3, then use Call Down the Lightning. If I wrote the name of the card wrong, it's the card that gives you +3 attack when you replace a reservit card, and if it's an Avengers card, it's +3/+3 you get instead.

Otherwise, do what I'm doing and run No Fear. It's still really good, and you still have effects that make you unstunnable anyway while team attacking.

Then again, I'm running both No Fear and Call Down the Lightning.

+3/+3 you say? how about combat maneuvers?
