E.T.C / Sideboard: Myra's Unstable Element, 2x Breakdance

Combo Setup: 
E.T.C., Band Manager and grab Myra's Unstable Element.
Anka, the Buried with Mecha'thun in hand.

Then you have 1 of 2 options, depending on if the opponent has minions on board.

Broomstick (Requires Enemy Minion on Board)
Cast 1 mana Mecha'thun + Animated Broomstick then cast
Myra's Unstable Element and Secret Passage, then kill the broomstick and Mechathun last to win the game.

Wild Pyromancer (If no enemy minions or no broomstick)
Cast Wild Pyromancer then cast Myra's Unstable Element
Then cast 1 mana Mecha'thun and finally Secret Passage 
to win the game.

If you're using Wild Pyro be careful to not kill the Pyromancer or Mechathun to early with spells, if you need to cast cards like Preparation or Counterfeit Coin cast them before the Pyromancer comes down.
