Self-Diagnosis
Is your deck running a pattern?
Twelve yes-or-no checks, four groups, live score. Open your seed 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 seed deck. The verdict appears here.
Each check is a place a real deck quietly loses. The patterns behind them, and the rest of the library, live in Pitchcraft.
