Undoubtedly, Elemental tribe is now one of the strongest in Hearthstone. So it would be wise to utilize all of the available Elemental synergies in a powerful class like the Mage.
This deck plays like a typical Tempo Mage, but with all the Elemental value. For example, Tol’Vir Stoneshaper gives you a taunt with divine shield for a mere 4 mana, while Servant of Kalimos discovers another powerful Elemental.
Since most Elementals are really strong, you could get some expensive cards out of this interaction -- like Blazecaller, or even Kalimos himself, if you’re really lucky. In this case, the rest of the match will go smoothly, and victory will be yours.
