I'm not sure what kind of card array the target uses.

Uncertain target uses akana array. In tarot cards, the uncertain target is played by Akana. Akana card array consists of 22 Akana cards, each card represents a different symbol and meaning, which can cover various topics and problems. This card array can be used to explore deeper problems and challenges and help people understand their inner and spiritual growth direction. Tarot cards, transliterated from the word "tarot cards", are called "the secret library of nature". It is an ancient western divination tool, which has been popular in Europe since the Middle Ages, and its origin has always been a mystery. This answer is for reference only. Don't be blindly superstitious.
