Its not great, you play a bad minion with no impact in a class that requires a strong curve to win games, has nothing to do with beasts, most good deathrattles are gone after rotation. This is a worse The Mistcaller, sure hope its fake.
Turn 6 vs Turn 2 or 3 is pretty important difference. Also the Mistcaller had bad stats for it's cost. 4/2 for 3 mana ain't half bad. It also will give a strong tempo build for a few turns.
It awkwardly doesn't fit Hunter all that well. Seems like it's main playstyle - no matter the version - is playing lots of cards that give you value now. This is mediocre now and gives you better stuff for the next few turns. Not bad, but question how good this is. You won't add extra deathrattles into your deck just for this, though.
