I wanted to take another swing at Hive Hexagon. I think while Xenan can work well with the card, it could really shine with Justice in the mix. Getting access to wonderful cards like Ghostblade Outcast (that no one ever wants to block), Deathwing, and Stonepowder Alchemist are all great ways to gain life. Desert Marshal keeps a lot of decks in check by silencing units like
Feln Adept, Grafters, literally any unit from Haunting Scream, you get the picture. Otherwise the deck plays good removal and notably, a Time market this time, not a Shadow one.
The Time Market gives you access to Behold the Truth which can really break a board stall. Machinations is generally good in every Time/Shadow deck. Grumbo's Platoon with +1/+1 and Charge has proven to be game ending over and over (thanks for Unleashing that on us Spiff). Disjunction for Relic removal on top of the 2 Display main. Excavate to get back key cards like Hexagon or Machinations while also triggering Hexagon is nice.
