In Hearthstone's upcoming Journey to Un'Goro, Shamans will get a spell in the same vein of Echo of Medivh. But rather than putting a copy in your hand when cast, you'll need to wait until the minion dies as the effect is due to a silenceable Deathrattle.
As if those pesky Wild Control Shamans needed more ways to get additional Earth Elementals.
Where do you think this fits in with a Standard Shaman deck though? Let us know!
