Curse of Naxxramas, the first Adventure mode content to come to Blizzard’s Hearthstone, is expected to arrive this summer. Blizzard has continued to tease the set by revealing cards slowly. Today, the big reveal is a new Mage secret – Duplicate!

When two Leper Gnomes just isn’t enough, there’s Duplicate. Let’s not even talk about the Mana Wyrms.

Also recently revealed is the Shaman card Rebirth, which will allow players to take advantage of a variety of cards that already exist and the pile of deathrattle cards found in Naxxramas.
