Forum:Bone Tower and Zombie World question

Let's say I have Zombie World, Soul-absorbing Bone Tower, and Substitoad out on the field. I tribute Substitoad to special summon a Unifrog from my deck. Does this count as special summoning a zombie and does my opponent discard 2 cards off their deck? Similarly, what if I have Zombie World and Bone Tower out and play Scapegoat? Does my opponent discard 2 cards? 69.116.155.192 10:29, 9 August 2008 (UTC)
