Basic AP deck, aiming for a low curve and consistency.
Early game:
I’m currently using both Justice Evangel and
Unfamiliar Interloper for the early influence boost and as sacrifice targets for Siphoner and Devour. There might be better options out there still, but these do the job. Blightmoth also works as a sac target, but usually is better saved as removal.
Rolant:
Try to keep devour open against opponents in primal.
Removal:
Annihilate hits most earlygame targets in expedition, and Just Desserts deals with Ambush units. Defile is probably another workable option, use what feels right to you. Backbreaker is your third source, along with 3/3 weapons from Siphoner.
Market:
Silverblade Menace preys on the high prevalence of Petition and Treasure Troves, and can be a win condition on its own when shuffled in with Wasteland Broker. Really this is the main reason I’m running Broker instead of an exclusively justice market.
Gates works to stall in the mid game, and combos well with any weapons you have.
Svetya can turn a small board advantage into a massive one, and is a fine shuffle target as well for more fun.
Makto is an experiment - he’s hard to deal with outside of silence effects and Swirl the Sands (from Grodov’s Burden), just keep him out of combat range until you’re stabilized. Important against matchups with Fire since Marley is really their only efficient answer to him. Also punishes people who don’t read cards.
Other considerations: opponent relic removal might be worth marketing, for Burden and other AP decks.
