Forum:Dragunity Equip Rule

My buddy uses a Dragunity deck and says that when he has Light and Darkness Dragon equipped to a Dragunity, its effect still activates to negate anything. I figure its not the case because 1)Its an equip card and 2)It has no attack and defense to decrease for its cost seeing as its an equip card. How would that play out? Also, can he remove a dragon equipped to a Dragunity monster to special summon Red-Eyes Darkness Metal Dragon? 63.135.7.59 (talk) 16:42, November 6, 2011 (UTC)
