Let's begin by saying that this Beast has incredibly high stats for such low cost. It also has one of the strongest effects for breaking enemy combos in the Dirty Rat effect.
Since there are several very strong combo decks in Standard right now, Wild Bloodstinger is highly valuable. You can break the gameplan of decks that run Mecha'thun, Antonidas, Shudderwock, for example.
On top of that, it will attack those cards and make it easier for you to finish them off. So definitely craft this one if you're aiming at playing Hunter this season.
