I have a question that I don't think has been asked before. Can you cast this card when your opponent attacks with a card whose attack cannot be nullified (Ex: Bal Burst Smasher)? I would assume so if the effects of the attacking card do not state "Your opponent cannot use or cast [counter]". This can be useful if your opponent pulls off an unnullifiable attack and you have exactly the amount of life points so you would be killed.
