7/15/2006: Haakon can't be played from your hand. It can't be played from any zone other than your graveyard, even if an effect such as that of Spelljack or Muse Vessel would otherwise allow you to.
7/15/2006: While Haakon is in your graveyard, you may play it. This follows the normal rules and timing for playing a creature spell; the only difference is what zone Haakon is being played from. The spell goes on the stack. You have to pay Haakon's mana cost and any applicable additional costs. The same applies for Knight cards you play from your graveyard while Haakon is in play.
