Tarot cards can be drawn at will regardless of any formation.

You can't draw cards at will when there is a card array indicating the order of drawing cards. For example, some arrays may be designed with psychological mathematics, and special numbers have special meanings. Therefore, when there is special indication, it is correct to draw cards in the order indicated.

If there is no indication, you can smoke at will in principle. But generally, for convenience, fortune tellers will draw cards in a fixed way (such as randomly drawing cards at a time or drawing cards from top to bottom at a time).
