Power Overwhelming

This is a build your ATK stat and take advantage of it by readying. Additionally, since she and her allies like energy, this deck is almost entirely energy resources.

To build her ATK stat, we have: Aggressive Conditioning, Combat Training, and Innate Aggression. So, we do want to be able to abuse this stat by readying ourselves. To do that, we have 3 Earth's Mightiest Heroes (with only Avengers allies in the deck), 3 copies of Spoiling for a Fight, Ready to Rumble, and a Battle Fury.

For Spoiling for a Fight, I usually just use this as a resource, hero ability fodder, or Energy Channel fodder until I have Blood Rage, Bambino, multiple ATK stat upgrades, or I'm just looking to gun down the villain. Depending on the allies I have in play/hand, it also might be worth using because 3 - 4 of our allies can swing for 3 - 4 damage, we might want a minion in play to get a tough from Throg, a minion could be stunned by Spider-Girl, we might be able to take care of it easily with Valkyrie, or we might be able to take care of multiple minions with Thor.

Hulk can be a good card to leave in play to power Earth's Mightiest Heroes or Iron Lad. Iron Lad can power Earth's Mightiest Heroes while waiting for one of our 3 ATK allies. While Sentry looks bad because of the encounter card, he can usually take care of whatever it spits out over the course of 5 rounds. It's not common to have a 2-THW ally in aggression and he really does help power up Iron Lad.

Quincarrier will help you keep alive through the healing from your hero ability while also cycling out poor Captain Marvel cards for something better. Hopefully, you'll be able to get Captain Marvel's Helmet to help you defensively. You can randomly draw it or put it into play via Superpower Training. That said, I usually prefer to recur Energy Channel if there's none in my deck.

I hope you try and enjoy the deck!
