Is Eight of Wands a yes or a no?

This card leans yes. It carries forward movement, and in a straight yes/no draw most readers take it affirmatively.

The Eight is speed. Everything that was held up releases at once and arrives fast.

The deck's clearest card of momentum, messages and things finally moving.

There are no people in it at all. Eight staves fly through open sky over a green landscape, and this is the only Smith minor with no human figure whatsoever. That absence is why it reads as pure motion: the card describes a condition rather than somebody's situation.

Yes/no readings are the most popular use of tarot and the one it is worst suited to. A seventy-eight card deck built to describe nuance is being asked for one bit of information, and most of what it knows is discarded in the process.

A more useful version of the same draw: read Eight of Wands as what shape this takes, not whether it happens. Rapid progress, news arriving, travel, a situation accelerating.

Delays end here. Act quickly and keep up, which is the whole of the practical advice and is unusually literal for this deck.

It is a good card for anything that has been waiting on somebody else, and a poor one for anything that would benefit from another week of thought. The window is the point.

Reversed, the lean weakens or inverts. Delay, misdirection, messages not landing. Momentum lost.

Or speed without aim: a great deal of motion in no particular direction, which is the version where everybody is extremely busy and nothing is advancing.

The most ordinary reading is the most likely: something that was expected has not arrived, and the card is describing the interval rather than a cause.
