Teach the engine what broken means.

Decksmith deals real opening hands from your deck and plays each one out. You judge: is this start broken, not broken, or borderline? Your calls train a model that learns your intuition — so "broken" stops being an arbitrary rule and becomes your palate, made reproducible.
