Justice League #30 (2014) (High Grade)

It all changes here! The next era of the Justice League begins as heroes quit, villains join and a Justice League roster you've never seen before emerges, led by the world's greatest hero—LEX LUTHOR?! As the dust settles and the bodies are buried, the violent consequences of FOREVER EVIL must be dealt with—while a mysterious new force sets its target on the League. But is this force friend or enemy? And why does he want Luthor dead? (If you ask Batman, it's a long list.)
