Valkyrie Aggression

A bit of an upgrade to the pre-con, focusing on her minion killing talent. I used this on the Sinister Motives campaign, and was lucky enough to pull the SHIELD tech that gives your basic attacks overkill, so Valkyrie tore through the villains.

Moment of Triumph is a great piece for Valkyrie's minion slaying, with that and Godlike Stamina, it's easy to stay in hero form for most of the game. "Bring It!" is awesome with Valkyrie, it is giving you a card for every minion, perfect to pay for all the Death-Glow attaching costs.

I used this deck to beat Sinister Motives on expert, paired with Iron Man Leadership.
