Score every Ancient blessing against your current build. See which ones boost your archetype and which to avoid.
Automatically detects your emerging strategy from cards, relics, and blessings. Tracks multiple archetypes simultaneously.

Claude reads your card rewards directly from a screenshot. No manual typing — works at any resolution, any layout.
Full dashboard — deck stats, archetype signals, win condition, priority picks, missing key cards, and blessing impact.
