I had someone complement me on how balanced this card was. Which is kind of odd, because when you design cards, you don't think to yourself "How can I make a balanced card?". Obviously, there's some Unholy Strength in here, and some Ravenous Rats in here, though I don't know how I got here. Maybe I thought of two well balanced cards and decided to make a third?

It's most reminiscent to me of Fill with Fright. But yeah, this is a combination of two reasonable effects to end up with a pretty strong common.
