I'm thinking either protection or justice. I've heard good things about aggression too though. Anyone else have any preference?

Justice is quite good due to a lot of good energy cards.

Leadership is also really good. She is the best hero for the Avengers Leadership deck because she has great resource generation and an Avenger signature ally.

Control Protection Captain Marvel has potential, I have not played it but I can see it working. Tho I doubt I'd call it her best aspect.

Aggression Capt Marvel was decent in the core set, but honestly, Ms Marvel Aggression is just plain better.

I really like her with Leadership.

I like her with Leadership or Aggresssion, as she has the big resources needed to pay for the, on average, more expensive Aggression aspect cards.

Leadership's probably best, but I also really like her on protection. The energy barriers synergize really well with her Rechannel, allowing you to minimize incoming damage and heal through what remains. You can stay in Hero form virtually all fight. Which is really cool, but also means you're neglecting her alter-ego resource generation, which is why Leadership is best for her, in my opinion. But yeah, protection's a really fun deck for her. Lots of great energy resources to throw at her abilities.

She's currently the best hero for a Hulk focused deck, because of her icon spread and what the icons hulk doesn't like are on.

But like most heroes at the moment, she's best as either Justice or Leadership.

I've mostly played her with Leadership and if felt pretty strong. Keep in mind that I only own Core set though, don't know how well she interacts with any of the new cards.

I also like Leadership above others.

Added to the reasons already explained here, I tried to check which aspect provided most and best energy resources, helping the obvious sinergy of those resources in the Danvers deck (rechannel hero action, photonic blast, energy channel).

We find at the moment that leadership adds 6 cards that include energy resource, and 3 of them are non permanent (which is better imo).

Aggresion adds only 3 (2 of them permanent)

Justice adds 5 (4 of them permanent)

Protection adds 6 (5 of them are permanent)

When measuring which is the best aspect, I agree that this question does not match the importance of the sheer quality of cards, but I mention just to add another reason. Leadership cards are good too, and I find the ally deck quite versatile and fun also.

There isn't a ton of good ones, but I would say Justic simply because it is the best aspect right now, and she does struggle a bit with mass thwarting, and is a bit slow.
