If Firestorm Phoenix would be put into a graveyard from the battlefield, return Firestorm Phoenix to its owner's hand instead. Until that player's next turn, that player plays with that card revealed in his or her hand and can't play it.1 "The bird of wonder dies, the maiden phoenix,/ Her ashes new-create another heir/ As great in admiration as herself." -William Shakespeare, King Henry the Eighth

10/4/2004: It may not be cast again until your next turn, but it can be put onto the battlefield by other effects.
10/4/2004: The "rebirth" is a replacement effect.
10/1/2009: The replacement effect works even for a copy card copying a Firestorm Phoenix. The copy card goes to your hand instead of going to the graveyard. It will cease to exist almost immediately afterward as a State-Based Action.
10/1/2009: The Firestorm Phoenix you return to your hand is tracked by its ability. As long as it remains in your hand, that particular card can't be played before your next turn begins, but a different Firestorm Phoenix in your hand can.
10/1/2009: The Firestorm Phoenix returned to your hand can't be played by any player (in case a spell or ability, such as the one on Mindleech Mass or Sen Triplets, allows an opponent to play a card from your hand).
