Apocalypse Rain

({p/r} can be paid with either {r} or 2 life.)
Destroy all permanents target player controls,
and that player's life total becomes 1.
Kicker {2}{p/r} (You may pay an additional {2}{p/r} as
you cast this spell.)
If Apocalypse Rain was kicked, it can't be
countered.
It is a nightmare from the skies...
