Earthen Might Card Review
This is a Shaman’s version of Mark of Y'Shaarj – +2/+2 and an extra card if the condition is met. However, unlike Mark of Y’Shaarj, this will fit into a slower deck more than into an Aggro build. Unlike drawing a card from your deck (which is fast), random Elemental can be bigger / slower. However, this will be a great fit into pretty much any Elemental Shaman build – Midrange or Control alike.
Earthen Might looks solid throughout the entire game. On Turn 2, you can easily play it on your Fire Fly to get a 3/4 minion to trade with AND you save your other half to activate Elemental synergies AND you get a random Elemental too. Then, later in the game, you can just play something bigger, possibly even a Taunt (e.g. Tar Creeper) and immediately gain small advantage on the board and an extra card in your hand.
This is basically an auto-include in any Elemental Shaman build. There is simply no reason not to run it.
