This deck is probably just ok, but it uses the new Rost as its hero, and I did get 7 wins (7-2) with it. I just wanted to play a fake Hooru midrange/control deck, and Rost, the Walking Glacier
The problem is that even in a 2-faction deck, Sediti is not very good for this event, and I can only run 2 merchants if I want to use insignias. And insignias are just too good (not to mention the other influence requirements.) At that point, you have to go back to 3-factions which are reliably the best decks for this event.
