Forum:Any help with this scenario?

So I was dueling earlier and a scenario happened and I felt like I was in the right with the card ruling but I think I may have been wrong. Can anyone help me with this?

First I played Wall of Revealing Light sacrificing 4000LP. Several turns later my opponent had 2 Alexandrite Dragon and a Red-Eyes B. Dragon on the field. On his next turn he summons Lord of D. a proceeds to attack with his dragons because of Lord of D.'s effect. I told him that Wall of Revealing Light does not target, it picks all his monsters. He told me that by picking all his monsters it is targeting. After trying to tell him that he is wrong and he could ask the people around us he got up and left. So what I correct or he? I would like to know that way if the situation comes up again with someone else, I'll know what to do. 68.226.66.17 (talk) 20:04, May 27, 2012 (UTC)
