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.
I don't know, it doesn't feel that strong at first glance at least. If it had been a battlecry, it would've been a different story, but as a deathrattle I think it's too slow for a hunter's game plan. Probably borderline playable in some greedy hunter deck, but that's it.
It's probably going to spawn about a 3-drop on average and that's just not good enough for a 7 mana 6/7 deathrattle.
Hunter has been given a lot of cards like this, but they have never seen any real play. This card is maybe cool at first loot on it, but hunter is agressive class and this card is not agressive. Maybe people will experiment with this one in the beginning, but when it comes down to successful ladder decks this is not gonna be included in them.
