Mulligans
Elemental Shaman
Win Condition: Grumble, Worldshaker
Strategy:
For most of the game, use elemental synergy to dominate the bored and slowly play out the bigger elementals. The win condition combo is to lower the cost of the elemental lords with Fire Plume Harbinger, then try to play them together and keep them alive with Stone Sentinel and Ozruk. As soon as you have all the big elementals on bored, you can play Grumble, Worldshaker and empty your hand next turn to fill your bored with huge elementals.
