King of Wands represents a man who has had his first Saturn Return; someone who has their Jupiter in Fire signs, in combination with Sun/Moon in ♌ or ♐.
Simply said, the King of Wands is a Manifestor that combines his charisma, intuition, imagination and life experience to reach his vision's goal and desired results.
Similar to Ace and Page of Wands - he doesn't lack in the libido department, and as such, he's very passionate both in his business and romantic relations. Although, unlike the Ace of Wands which symbolises erection, and Page of Wands represents a young and foolhardy man in heat, the King of Wands brings his experience and discipline into sexual encounters. As such, he can be a fantastic partner for Tantra, and magical/spiritual rites in general!
If the King of Wands comes up with Death XIII or the Devil XV, we know that Pluto and Saturn have their cosmic fingers in this spiritual pie, thus the man in question is not naive (at all), and despite knowing how to make use of various aces up his sleeve, he can very quickly be prone to violence, severe jealousy impulses, possessiveness and insecurities due to inner-child complexes and unhealed traumas.
When the King of Wands comes up with 4 or 9 of Swords, it can point to erectile dysfunction, and then, depending on the rest of the cards within the reading, we can deduce the spectre of possible reactions.
One should act diplomatically and moderately (Temperance XIV) when dealing with the King of Wands if the 'maleficent' cards come up with it. And if the entire reading sings of 'bees and flowers' (3 of Cups, 4 of Wands, 10 of Cups, 10 of Pentacles), then rejoice, for your axe fell into the honey jar.
People who have a firey spirit are especially jolly when the King of Wands comes up in a generally positive reading, for then the near future filled with adventuring, good times and creative productiveness awaits!
It's not for nought that the King of Wands is depicted with a lion in the background, he is the one who has mastered Strenght VIII, and in his arsenal of wonders, he holds patience and wisdom gained with the first Saturn Return. He is a changed man, a man who has the creativity, vision and imagination, but also the drive, perseverance and patience to see his dreams and goals come to full fruition.
The only one scarier than him could be the King of Swords for that man lacks empathy and detaches from his emotions perfectly, in order to execute his machinations. King of Wands still has a beating and a warm heart hiding in his ribcage, and he has a (very) soft spot for animals. He is, after all, depicted as a salamander, and his totem is a big cat.
If you get a chance to interact with animals in front of the King of Wands, you will either win his heart over or invoke his wrath, depending on how you treat the animals. Having King of Wands on your side is like winning the grace of a volcano over, so be wise in how you treat those "below" you, those who can't do anything for you, and you can do everything for them.
After all is said and done, King of Wands is still the Ace of Wands in his heart of hearts - a softie who cares about all living things with immense passion and righteousness. He might be seasoned and wise, but he is an advocate for justice, and of high moral ground.
Either way, when the King of Wands comes up in a reading, be prepared for firey occurrences and creative brainstorming, especially if he represents your boss (or a manager), and there's a project to be finished.
