Commander is the official title for what was previously known as Elder Dragon Highlander, a casual fan-made and maintained format that has been around for many years. While the format will still be maintained and controlled by the players, Wizards will be releasing Commander decks that will include some older commons and uncommons that, while not particularly valuable, are harder to find due to their age. In addition, 51 new Eternal format legal cards will be included among the decks.
