Re: What Captain America graphic novels would you recommend?
For Non-Brubaker material I recommend Stern's War and Remembrance and Englehart's Secret Empire, which was the first great multi-issue Cap arc.
Dream MCU phase 3:
2016: Thor: Ragnarok, Doctor Strange
2017: Captain America: Secret Empire, Black Panther
2018: The Incredible Hulk: Rise of the Leader, Guardians of the Galaxy: War of Kings
2019: The Inhumans, Avengers: Thanos Imperative
