This is exactly the same list that LightOutAce and TheBoxer played at the Quarterly Championship.
The deck is great and took me easily to master.
The only thing I was not satisfied with is the Emerald Waystone in the market, I almost never took it, but since the above players are far more experienced than me with the deck I will trust their choice for now.
I will try to write a detailed guide, once I get more repetition with the deck.
However, there are 3 copies of this deck in the top 16 of the Quarterly Championship, including 1 in the top 4.
I think that it is a very well rounded deck that has currently good chances against everyone. Usually, you are not a huge favorite against anyone but is more like a 55-45 odds in every matchup. Probably you need to get some more repetition with the deck and tune a bit the way you are playing. Or maybe you just were unlucky in the 17 games you have played.
