Here is another Elemental deck, and this time in Shaman class. Rastakhan's Rumble introduced a new elemental card for Shaman -- Bog Slosher, a 3-mana minion that returns to your hand and buffs other friendly minions.
It's not only a great way to both heal and buff a damaged minion, but also re-use its battlecry. That is also the reason why this list includes Murmuring Elemental that triggers battlecries twice.
So you could say that this is a value deck with some very good synergies. For example, you could play Elementary Reaction and Earthern Might and get a ton of new cards in just one turn. This combo alone will supply you with a big hand very early in the match-up.
