What kinds of tarot cards are there (such as Waite ~ ~)? What is the tarot card with a khaki cover, which is a little classical but very authentic?

The one you're talking about is Waittarot's packaging. Tarot cards can be roughly divided into Waite, Thoth and Marseille (this system is controversial), and some divination cards and Oracle cards can't be called tarot cards strictly, but there are too many kinds. If you use it, it is Waittarot. The version of the khaki cover is Waite's original, with strong colors and lines. If you buy a domestic classic tarot card, that version is the standard knight Waite.
