Secret Aggression Man

Trigger preparation upgrades to load up the suit form upgrade via Secret Agent then spend those counters to boost attack events in Assault form. There's no limit per phase, thus multiple attack events can pop off for damage well above the cost curve.

Melee and One by One are multiple instance attack events, so the suit upgrade spend boosts both instances of damage. Easily defeat a minion while also punching the villain.

Man on the Wall exploits Nick's solider trait to pay for multiple instance attack events when multiple minions are in play.

The Winter Soldier ally helps manage both minions and threat, having some synergy with Looking for Trouble.
