Self-Diagnosis
Is your deck running a pattern?
Twelve yes-or-no checks, four groups, live score. Open your master deck in another window, answer honestly, and the verdict updates as you go. Nothing is stored and nothing is sent — this runs entirely on your side of the screen.

Tick what's true of your current master deck — the verdict appears here.
The checks come straight from the six patterns' failure modes — each one is a place a real deck quietly loses. The patterns are in Pitchcraft; the rest of the library is on one page.
