let's assume the card effect is translated right (still doubt it's translated well)
The effect is kinda bad The Mistcaller had this effect on greater scale for a tempo loss aswell this card is limited to DR minions in your hand, would be great in warlock but in hunter your hand size is normally quite small,
in aggro you just don't care and top deck lethal.
in midrange you play 1-2 cards max per turn.
There is yet to be any realiable hunter draw spell so you can't assure you will have DR minions..
it's also not a beast which really matters in hunter(worgens aren't beasts so it's ok)
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.
