Flames of Aerith

As you cast Flames of Aerith, choose any number
of target creatures you control. Flames of Aerith
costs {1} or 1 life extra for each creature targeted
beyond the first. Put a Sigil counter on each of
those creatures.
{r/w}{r/w}, Sacrifice a creature you control with a Sigil counter on it: Flames of Aerith deals damage
equal to the sacrificed creature's power to any
target.
