This new priest legendary from The Witchwood could be a more powerful Shifter Zerus.

[Insert Monster Hunter joke here.]

    Class: Priest
    Card type: Minion
    Rarity: Legendary
    Mana cost: 1
    Attack: 1 HP: 1
    Card text: Each turn this is in your hand, transform it into a card your opponent is holding.

An interesting card; more playable Shifter Zerus, perhaps? Even if a player doesn’t put this minion onto the battlefield, it’ll still be useful for seeing what the opponent is holding in their hand.
