The Grace of God

Shroud, Flash unless you pay {3}{w}{g} to cast
The next time you would lose the game, you don't. If your health were to go below 0, it goes to 1 instead. Then sacrifice The Grace of God unless you exile all permenants you control. This must be at least 7. If you do, your life total becomes equal to your starting life total, and you draw up to 8 cards. Then take 2 extra turns after this one. You have no maximum hand size until this resolves.
You may cast The Grace of God from your graveyard for {7}{w}{g}
