This is a not-very-competitive-but-fun deck whose objective is trying to achieve an OTK via Highkeeper Ra.

You play it like your usual Exodia Mage, but there are a few differences. Before the combo:

• Both Mogu Cultists must get a tick from Emperor Thaurissan.
• You must play both Simulacrums with both 0-cost Mogu Cultist in hand, we must have 4 copies in hand.

Then, the combo is:

• 4xMogu Cultist (0) + Echo of Medivh (4) + 3xMogu Cultist (3) + Drakkari Enchanter (3)

Of course, it is not easy to survive long enough to achieve it, but the outcome is so satisfying. The more cards you hit with Thaurissan, the earlier you will be able to perform it.

Witchwood Pipers are there to help you draw the Cultists.

I also thought about adding cards that can create copies of a minion, but that would fit better on a 2-turn kill with Open the Waygate. Definitely worth experimenting!
