Assume the Constable is discarded early in the game through the effect of a Prince or Bishop guess. So it goes to the Card Graveyard, but the (6) skull is visually shown to differentiate it from King.
But if would be nice that there is a visual difference when it is discarded by play, or discarded by effect, as several turns in, no one recalls how it was discarded.
