Crumbling Ruins

{t}: {b}{b}
{3}, {t}: If you would lose life, you may instead sacrifice a creature for each 1 life lost. For each creature sacrificed, put a +1/+1 counter on target creature. If a creature with +1/+1 counters on it is sacrificed, you may gain X life where X is how many +1/+1 counters on that creature.
The smell of rot and destruction fills the air for the horrors to savor its aroma.
