Bringing Endra back for Echoes of Eternity.
Winchest Endra is built around revenge buffs in Swear Vengeance and Touch of Resilience, tutors in Reweave and Rujin's Choice, and void recursion in cards like Dark Return and Display of Ambition. When you build an Endra deck with justice in it, the only merit is for the tutors you gain access to. In Winchest, this means you also lose a lot of the raw draw potential from cards like Honor of Claws or Nahid's Distillation, so you need to make other concessions with the card draw, like putting in Kindling Carver in a deck with 8 other units.
Endra: fairly standard, needs no explanation
SS Banner: Banner helps you meet influence/power requirements
Bore: fairly important attachment removal. You lose really hard to Avigraft and Gavel, and as a result you fairly consistently need access to ways to remove it.
Quarry: Quarry helps you if you start to gas out in the later stages. I don't like Demand Death, so running Quarry as draw seems like the best option
Cremate: hard removal for Tocas. He ruins this deck rather hard, so including it to deal with him tends to be pretty useful.
