Forum:Question regarding hysteric party

So I was dueling a friend who was using Harpie Ladies. I used royal decree and he said he could activate hysteric sign in response, even though it's a continuous trap, not a counter trap. Royal Decree is supposed to negate all trap effects on the field. Can he do this or is this breaking the rules? Yeeeeeah! Now it&#39;s a party! (talk • contribs) 06:42, January 3, 2015 (UTC)
