Considering how fast Goblins can get out of control, this isn't a bad option as a boardwipe. Since it only targets one type of creature, it's pretty much relegated to the sideboard, but it still functions nicely for what it does. It comes out one turn earlier than Wrath of God and can easily be a one-sided wipe, which makes this situationally great.
Pros: Cheap Goblin wipe
Cons: Only hits Goblins
