At the beginning of the game, if this creature is your commander, legendary creature and planeswalker cards you own everywhere that are flavorfully heroes or villains in their world gain that respective type. (For example, Gideon becomes a hero and Yawgmoth becomes a villain. Yes, planeswalkers get creature types this way. Don't worry about it.)

During each of your tums you may cast a Hero or Villain card from your hand without paying its mana cost.
