This is the Clutchmother Zavas 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: Whenever you discard this, give it +2/+2 and return it to your hand.
You can get Clutchmother Zavas by opening packs from the Journey to Un’Goro set.
*Some obvious discard synergy, and interesting to see a Beast card for Warlock.
