Flying As Iona, Shield of Emeria enters the battlefield, choose a color. Your opponents can't cast spells of the chosen color.
Pro Tip! Against certain decks Iona is just lights out. Combo decks often get a key component shut down and mono-colored decks...well, you can see how that goes. Iona, Shield of Emeria is currently banned in Commander.
