A shadow list focusing on cards that 2for1 in your favor such as
Rhysta, Acantha's Herald.
Vara's Favor alongside baby Vara take care of Aegis. Eremot, MIndsplinter has been surprisingly good, as the AI never plays around its abilities and has offed itself many times.
The market consists of a sweeper, 2 inscribe cards that serve as extra sigils mostly but often are played as threats. A neat interaction is to play
Fear and hit your land drop alongside binning your opponent's warcried unit/weapon. This has happened to me twice in the last seven matches, so it's more relevant than not. Otherwise, just a mana curve heavy on the 2 cost cards to let you survive on those mana screwed hands we always seem to get in Gauntlet.
