The Marvels

Cameo Ms. Marvel from Nova's hero kit. Then Sidekick her. She can recur events, including Side-by-Side, which will heal the damage she takes from bringing the event to hand. Boost her hit points further with a Reinforced Suit.

Spectrum wants to be played using Power of Leadership to get the maximum benefit from her ally ability. Hold Spectrum in Avengers Compound and/or hold PoL in Resource Reserve for the right moment. If she or Ms. Marvel are defeated, they can hang out in the Med Lab instead of getting lost in the vacuum of space (aka discard pile).

Team synergy with Lead From the Front, Teamwork, and Unified Strike, all of which have energy resources for Captain Marvel's hero ability Rechannel or powering up Energy Channel.
