That's good. They're trying to make a slower more control version of Hunter work and Deathrattle Hunter is a good deck to do it with. Plus you have cards to trigger your deathrattle effects and you have big ole N'zoth for late game.
Look at the direction hunter is looking to go, this card might actually be kinda decent. Turn 6 hero card deal 2 to everything gain 5 armor and change your hp, into this card to establish a solid board with a solid deathrattle effect.
I mean, I'm just saying. It seems to make sense. On top of that, the deathrattle is really good when you take into consideration that stat distribution on this card as well. Now imagine if some type of control hunter makes an appearance and it involves nzoth, this card and many other to come out. Cmooon reveals :D.
Synergises well with Deathstalker Rexxar, but is slower than glacial drift to get it off. It's difficult to see games - even in a slow control meta - where Hunter remains alive for the protracted periods necessary to make this truly viable.
