50 Decay scrolls. A great way to boost your collection! Who is Irva? Some say a test subject of Nuru who went mad. Whatever the case, Irva has powerful undead synergy and that's what this deck is about. Irva's Curse is an interesting take on an aggressive deck. Although they are slow, the undead forces of Decay can overwhelm and take your opponent by surprise. If you fall behind, scrolls designed to directly damage your opponents' idols can close out a victory.
