I have to ask: other than being really fun flavor/theme-wise... what do you see this card most useful for? Who would you put it in, and what targets would you be looking for?
Additionally, is this the kind of card you feel should be discussed before played? Or is this the kind of card you're going to whip out just to cause some friendly hijinks and fun stories?
These sorts of cards are very interesting to me because they are verging on the edge of potential griefing tools. Ideally, they should not be used for that, but what should they be used for? And how much table talk will you allow?
