the more I think about it, the more I like this card. At first I thought this was a six drop, and immediately thought how mediocre it was. But because its a 5 drop, and with all the good 5 drops leaving the game, this might have seen play on that merit. Now you have a control shaman's dream effect tacked on.
Overall pretty decent with a good stat-line and a useful, if somewhat bland effect. Also as others have pointed it does have combo synergy with AoE effects like Lightning Storm and Elemental Destruction
I'm just another one of those. You know, those who do things. Things that need to be done by those that do these things in order to do those things that don't do these things themselves. Has the word 'things' lost meaning to you already?
This card could be really good for a control style shammy, I mean think about it, if your losing to agro, and you play this turn 8, you could board clear, heal to full and still have a body. Its like Reno Jackson but more combo-ie. I think this might see some play.
