Mulligans
Play elementals. Play battlecries. Play Shudderwock. Consider Shudderwock an elemental chain card.
The Corpsetaker package can be replaced with the Tol’vir Stoneshaper. I’m not to big a fan of Al’akir. Tol’vir accomplishes just about the same thing. MC tech and ooze are considerations. However, they mess up the elemental train.
