Eternel Darkness have been changed during the last update: The Enchanted Grove. It now cost 8 gold and summoned a squad of zombie n a 3x3 area. It also have Dramactic Entrance, making spawn block possibility next turn. Also, it can be buffed by cards such as Armory, or Necromancer. This is make a very threatening card when they have man board buff on the board. Because of this, many people run Swordsman in order to prevent spawn block from happening. Redmaster didn't rate this card yet, but I predict that he would rate it a rank-A class card. It is a powerful card that summoned 18/18 stat on the board, but there is many board clear that punish the player.
