In case you're looking for the same thing in red, try Power of Fire. (It could be considered a planeshifted version.)

In that case, you probably want to run Fire Whip instead, which can also be sacrificed for 1 damage. It can only be cast on your creatures, but it's not like you were planning on making one of your opponent's creature a pinger anyways.
