Madame Lazul has now been revealed as one of Priest's Legendary cards in the upcoming Hearthstone expansion Rise of Shadows! The card is a 3-mana 3/2 Legendary minion that reads, "Battlecry: Discover a copy of a card in your opponent's hand." This seems pretty good on its face, as it not only gives you information about your opponent's hand and deck, but you also likely get a pretty good card out of it!
