... who would be on your roster?
Rules of thumb to follow: New 52 is in effect, has to follow the Hickman concentric circle grid (use ALL 24 slots, so 4 teams of 6), may use a character if s/he hasn't made a New 52 debut unless it infringes on DC mandate (i.e. Wally West, Donna Troy, Stephanie Brown, Cassandra Cain, etc.)
Core founders - Superman, Batman, Wonder Woman, The Flash, Aquaman, Cyborg
