Eldest Hellfire

Target creature you control deals damage equal
to its power to each other creature and each
opponent. Whenever a creature dies this turn,
you may pay 1 life. If you do, return target
creature card from your graveyard to your hand.
"The skies will darken from the ash of the unbelievers,
the oceans will boil into tarnished salt, and we the
living and the dead, shall burn at his side for all
eternity."
— Grimoire of the Eldest Oblivion
