Agent Coulson and the newly-reformed Squadron Supreme of America are wading into Marvel's War of the Realms event beginning with April's Avengers #18. The series is written by War of the Realms writer Jason Aaron, with the returning Ed McGuinness on art.
Agent Coulson and the reformed Squadron Supreme returned in November's Avengers #10, recruited by Thaddeus "Thunderbolt" Ross to be the United States government's superhero team following the Avengers distancing themselves from working strictly for one country.
Here is Avengers #18's advance solicitation. Look for Marvel Comics' full April 2019 solicitations later this month on Newsarama.
