Dogiragon, Flaming Revolution

Triple Strike, Flying
You may sacrifice a red non-token creature with flying, rather than pay the cost of this card. When
you put this creature into the battlefield if your
life is 2 less or 0, you can't lose the game and
your opponent can't win until the end of your
next upkeep. Whenever this creature attacks, if
you have no hands, untap it. After this main
phase, there is an additional combat phase
followed by an additional main phase.
