After the first two scenarios of The Circle Undone, the Diana/Preston team is starting to better define their roles. With the initial 10xp, Diana has leaned farther to melee combat with the addition of Timeworn Brand and Ace of Swords. With these two cards out early, Diana can reliably hit for 6 str and 2 dam, and save up her big bang for when she's built up some cancel will.
Other useful early upgrades were Vicious Blow(2) and Ward of Protection(2) to make up for the single core set limitation on these cards. Uncage the Soul was dropped as this deck is moving away from a heavy investment into spells, and resources have been plentiful in the first two scenarios. Hopefully that will prove to be a wise choice. Both Delve Too Deep cards were also replaced.
