The Flavormancer

Legendary Creature — Hero Villain

Before the game begins, if The Flavormancer is your commander, legendary creature and planeswalker cards in your deck that are flavorfully Heroes or Villains gain that creature type. (For example, Gideon becomes a Hero and Yawgmoth becomes a Villain. Yes, planeswalkers get creature types this way. Don't worry about it.) Once during each of your turns, you may cast a Hero or Villain spell from your hand without paying its mana cost.
