How to build Iron Man?

So I've had the core set since 2022 but only just really gotten into the game.

I have:

* Black Panther

* Captain Marvel

* She-Hulk

* Silk (bought her last week)

* Spider-Man

* Star Lord

* Venom

And then there's a pile of Iron Man cards I want to use. I really like She-Hulk and don't want to break her down for the basic Iron Man deck. How do I about collecting more cards to build Iron Man? What archetype should I focus on for him?
