If this was a battlecry effect I would still think this was a bad card.
Now it is a deathrattle which makes it even slower, and even a worse card.
You can't run this in a mech deck because you need to guarantee it hitting a deathrattle mech so it goes in a deathrattle deck and won't win the game there.
[sarcasm] YES. As Battlecry it would be such a bad card..... Getting 3\4, 7\7 and 2\2 deathrattle that will give another 7\7 is not a big swing by any standards. 3\4 + 9/7 divine shield is a joke too. 3/4+deadly shot+2/2 with a deadly shot deathrattle would also be a crap. [/saracasm]
That is why I said hunter players will need some time to learn how to play again, they become to used to simple spend 6 manas and win the game, if the new cards don't do this they think is crap.
