Went 43-10 in the event and currently sit at 10 on the leaderboard.
Nothing too surprising here; Winchest still has a lot of good cards, and you can just keep dropping bigger and bigger threats.
Xo was already the best Hero for this type of deck in my opinion, but with the release of Dark Frontier, he got even better because you can now run 5 merchants/smugglers for consistent market access. Typically, the first merchant will put Xo into the market and the second can pull him back out providing consistent card advantage even if you miss the card draw options.
Also, Dark Frontier added even more Justice removal, so this deck can counter just about anything. Added the best new cards from Dark Frontier as well like Eclipse Dragon
, Pristine Light
, Minotaur Platemaker
, and the perhaps surprising Vishni, Lethrai Highblood
