This is the New Card The Curator revealed as part of the sneak-peak of the upcoming adventure One Night in Karazhan. It’s another legendary, the other revealed legendary being Barnes.
It has a powerful flavour text reading: Taunt. Battlecry: Draw a Beast, Dragon, and Murloc from your Deck.
The card draw is pretty powerful and value wise makes up for the low stats of 4/6 for a 7 mana card. But it’s all very situational and you need to build a specific deck around this card and draw your cards in a favorable order.
This is a card that needs some testing before we can make a real decision on how strong it is exactly. So I’m interested to see this card come out and what decks people can build around it.
