This is the Xixo Totemic Might Shaman Deck Sep he was playing on stream. The games I saw he didn’t even lose a match with this list. There is only one Wicked Witchdoctor, with the list leaning on its burst damage to be the main win condition.
It’s more like a midrange list with 1 x Totemic Might and 1 x Wicked Witchdoctor. It was very effective at high legend, so give it a go and see how you get on.
