With families out for Atlantis. Maybe add some features for older heroes where they can trade mats or some sort of expendable resources to have them join a family? We have alot of cards kind of falling into “types” with most recent being the holoween event and vampires. Why not add:
Knight or knighthood
Etc. Families. This could go along the lines of what SG said about wanting to allow heroes to advance thier current strengths or even new skins. Ilhell you could have a new guild house for families as a new building in our bases.
