The Major Arcana Tarot Card allocated to the sign of Scorpio is The Death card. The general meaning of this card is transformation, regeneration, inevitability, rising again, reaping and sowing, releasing and recyling, and the surrender of the desire nature.
The Minor Arcana Cards of the Five, Six and Seven of Cups have a less obvious connections to the sign of Scorpio. However when a Decan Wheel is consulted (see image below), the first Decan of Scorpio, Oct. 23rd to Nov 1st, is found to correspond to the Five of Cups. The second Decan, Nov. 2nd to the 12th, corresponds to the Six, and the third Decan, Nov 13th to the 22nd, to the Seven. If your Sun sign is Scorpio, you can determine which minor card is “your” card, and it can be used as an alternate Identifier, or you may contemplate how the card is thematic in your life. Additionally, using the Decan Wheel allows for time or dates to be introduced into readings.
