Great Justice

A great mono-J Gauntlet deck that I've been running and tweaking continuously since I started playing in 2016. Even now, I find mono-J to be the most consistent Gauntlet deck type. This is more of a controlling midrange version.

Early Plays:
Justice Etchings, Lingering Influence, Copperhall Porter, Hojan, Crownbreaker, and Icaria, Valkyrie Captain are all cheap cards that either pull power out of your deck or ramp. Don't forget to hold Hojan, Crownbreaker in hand unless you have Finest Hour or preferably Silverblade Intrusion to protect it or just to make sure you get the value off it. Justice Etchings can also be used to trigger Hojan, Crownbreaker if you have the influence requirement.

Mid Plays:
After turn 2, play removal as needed, or just slam Unseen Commando and Valkyrie Enforcer. Copperhall Bailiff is great at neutering aggro and aegis decks. Winchest Merchant can grab an early use Lay Siege or Pristine Light, or it can grab Reweave to replace itself with something more useful.

Endgame:
Harsh Rule resets the board. Sediti, the Killing Steel gives you overwhelming card advantage. Biggest finisher in the whole game, in my opinion, is Telut, Queen's Hand. Pull it from the market when you have a unit on board and can slam it and attack with someone.
