This is the New Paladin Card Ivory Knight to be released as part of the new adventure One Night in Karazhan. It’s part of a chess board battle that takes place in the adventure.
This is another card that gives healing to the Paladin class. Combined with discovering a class spell makes this a great value card if you discover what you need in your current game.
Looks like a nice balanced card on the face of it. Will have to see how this one plays out once you can try it in different decks and see how effective it is.
