This is a funny card - I love it. What can I say, all the good points have been stated already.

From T1 Dark Ritualing to play this on your opponent, to combining this with means that let you copy this card to mess with your opponent, to using it like a black Timetwister. I definitely think it's more than a mere 3 stars - maybe not a 5 stars, but in its own right very useful and annoying. The troll in me is squee'n with joy. :D
