This is the Runic Egg HS Card released as part of the card set unlocked in the adventure One Night in Karazhan.
It’s a 1-mana cost, 0/2 body card. The card reads: Deathrattle: Draw a card.
It’s hard to see where and why you would put this card into a deck. 1 mana is a cheap way to cycle a card so maybe this card will find its way into decks that need to cycle hard for a combo. But it’s not a good card and isn’t going to shake up any decks builds, that’s for sure.
