The Judgment is the card of revelations, announcements, awakenings, rebirth, absolution and of course judgments. The Queen of Swords represents the power of the mind from which actions and decisions arise. The logical -rather than emotional- process of information. Such a combination could indicate a clear decision, made after a discovery or epiphany.
The elements of the cards are Fire (Judgment) and Air (Queen of Swords). A very energetic combination, which leaves no room for second thoughts. There's the risk that a situation can get out of control or to extremes, if the right balance between the elements is not achieved. In other words, the dynamic of these two cards could either have a purifying or a destructive effect.
