Dark Necrofear can be Special Summoned after removing from play, on your side of the field, 3 Fiend-Type monsters in your Graveyard. Her Summoning requirements are rather easy, you can use cards such as Giant Germ, Painful Choice, or Magical Merchant to get monsters into the Graveyard. You could use her as a wall to block any attacks, or just ram her into another monster on your opponent's side of the field, and get it at the end of the turn. Date: March 23, 2006
