I exclusively played this list to masters and maintained a solid 62% winrate in Diamond. This deck is quite good against aggro with a solid early game +
Hailstorm. The card that surprised me the most is
Sodi, Wingbreaker. She is really good in this shell since it's really easy to trigger both onslaught and the card draw.
Xumucan, the Surveyor and Sabertoth can be some nasty surprises and basically no one ever plays around them. I also think
Xumucan, the Surveyor is needed in this deck as this is it's otherwise not great against control.
Jotun Hurler is another anti aggro tool and great with the 6 Merchant setup.
Strategize feels like the best draw option in that slot (because of Hurler). Cycalis, the Burning Sand makes quite a lot of starting hands playable and allows us to keep that greedy power base. There isalso the choice of swapping Equivocate with
Ice Bolt from Market to Main, but
Ice Bolt feels much better in main
