Forum:Tyrant’s Tantrum

When I activate Tyrant’s Tantrum, I only have to tribute the 2 monsters when I activate it, right? Or do I have to tribute 2 monsters every time my opponent activates spells? I a little confused, but I think it is the former. Help me clear up my confusion. -- Dark Ace SP™ (Talk)  12:40, May 22, 2011 (UTC)
