I've played a lot of versions of Cultist aggro-ish decks, and just hit Masters with this version, going 11-5 in the last stretch.
The deck just so happens to be very close to an Expedition list, which was entirely by accident. The addition of Smuggler's giving you additional 3's for Machinations is pretty big. Balancing the various 1,2 and 3's is a delicate dance, and there have been a lot of cards in and out of various versions.
I've gone back and forth between Dova and Nahid's Distillation main or Market. Dova getting the main currently because of the interaction with Vox, Nurthuring Sadist. The Pledge is some nice icing though.
The Market is still very open, as I haven't done a deep dive in options since moving Crack the Earth out of the deck, and hence moving away from an entirely 5 cost Market.
