Kinda good card if it stick can be combo with grandmother and some other card on curve however might still lack some death rattle cards to make it cut and 5 drop is a dead draw early game(well mabye not so much)
Seems quite good, the stat distribution is nice, can be comboed with grandma. Although not sure the effect is that good in hunter, since the hunter doesn't have much draw, and you won't have that many minions in hand.
It feels playable, but the ongoing effects always need some immediate value. When it dies or when you do not have deathrattles in the hand, it was a 5 mana 4/6. Nesting Roc seems a better option in these cases.
Of course, you could have some stuff like Kindly Grandmother or fiery bat in your hand and empty your hand, but that will likely also be not very often the case. So I think it is not enough.
Effect is very strong, but it won't adress hunter's main issue for playing heavier decks which is lack of control tools and proper cycle. Emptying your hand can also be a very bad play for hunter, which is important to remember.
