Since we don't have a Justice League Dark comic, and the main members of the Justice League mostly have science-based powers and are always fighting alien conquerors or cosmic beings. If there was a magical threat should the Justice League ever encounter, should Wonder Woman or Aquaman use magic if the Justice League faces a powerful magic-based villain? Or should they call magic-based allies such as Zatanna, Dr Fate, Constatine, etc.?
Between Wonder Woman and Aquaman, I'm leading towards Aquaman because the Atlanteans to me seems more magic-savvy than the Amazons who are a warrior race with limited magic resources.
