Voracitase

If a creature would die, instead exile it and put a
croak counter on it.
Voracitase's power and toughness is 1 + the
number or creatures with a croak counter on
them.
When Voracitase dies, return all creatures with
croak counter to the battlefield, except they are
1/1 blue salamanders and lose all other creature
types.
{b}{b}, pay 2 life: All other creatures get -1/-1 until end of turn.
