This card went through a lot of changes before it made it to this form. When I first created this card a few years ago, it was an enchant permanent that did 1 damage to the permanent's controller each turn. It was a common that cost R. I called it Heat Curse and filed it away.
As I was looking through my files for a card to post, I found it again. I saw it and immediately thought of a similar card in Innistrad. They even made it a Curse! I wanted to make it more special, so I added a sense of urgency to it. A very red sense of urgency. This is the perfect card to put on an annoying opposing creature. It's fun to watch your opponent squirm trying to get rid of his own creature.
