This is the Lakkari Felhound HS Warlock Card from the Journey to Un’Goro expansion due for release in April.
It’s a Warlock class minion and the card reads: Taunt. Battlecry: Discard two random cards.
You can get Lakkari Felhound by opening packs from the Journey to Un’Goro set.
*A strong early game taunt that interacts with the Warlock quest card.
