Seems good. Deal 8 damage (potentially two targets), gain 8 life, and maybe even survive, remove some minions, and even an elemental tag (though that seems less relevant, I think there's only two cards in standard that benefit from that).
A good replacement for Al'Akir the Windlord? This is also a great late-game healing option for Shaman, especially since Healing Rain is rotating. If Blizzard reverts the nerf to Flametongue Totem, this would basically be a 10 mana Healing Rain + more if it survives or is not cleared immediately.
