I have some ideas for cards to put in this deck but im not sure which ones to choose. My friend told me he'd sell me one of these 2 cards: Vampire's Curse or Caius the Shadow Monarch and if I buy either one he will throw in these 4 cards: Zero gravity,Dragged down into the grave, D.D. Capsule and Chaos Necromancer. I might also buy Reign-Beaux, Ruler of Dark World. So plz rate and comment and suggestions!!!!!!!
