1. The magician (The magus of power)

Alchemy symbols: Fire (Next to the candle at the right foot of the magician), Earth (Between the athame and the flowers), the symbol of water in the chalice, the air below the chalice and the planet mercury resembles as the "sun" in black sphere.

Basic elements: The candle, athame, flowers, cards with a draw of a pentacles inside, the chalice and the swords. Those elements has multiples purposes. The first one is represent the minor arcana: the flower as the wands; cups as chalice; swords (isn't obvious), the pentacles as  the star of David. Also there is the presence of the four elements (besides for the elements of the minor arcana) , candle as fire, incense (the "smoke" behind the magician) as air, the water inside the chalice, the flowers as earth. The magician is inside of the circle made it by all the elements. As it knows, every work done by the magician should be protected with a circle.

Clothes of the magician: He is wearing a hat  with wings in the sides. long tunic that only show the hands and barely the foot. His left hand is holding a parchment

Mercury, in this case, is upper middle part of the card. Also Mercury is enclosed by a black sphere and between it, there are 2 wings (apparently eagle wings). Just below the black sphere, there is a big flower blooming, the petal of this flower is in fact snakes. 
The magician is holding his wand with the right hand and in the upper end, the wand has the star of david. The star of David in the wand is emitting a wave towards to soil (to be specific to the naked man). Also, the man is point to the start of David from below with his right hand and the other this man is holding a caduceus. The naked man is emitting a wave from his center of mass.  

Between the magician and the symbol of earth, there is an hebrew written as דפאל, tin hebrew this means Raphael, therefore this card is under Raphael Angels representation 

Extra notes: This card makes honours to its name. There are some hidden concepts of hermetism such as "As Above, So Below." (the waves from the wand towards to the soil and in contrast the wave from the man towards to wands). The caduceus is a symbolism of hermetism. 
Meaning of the caduceus according to wikipedia: represents number 8 (equilibrium amongst antagonist forces). Also represents of the eternal cosmic movement, the foundation of regeneration and infinite. It is the formal vertical symbol of the infinite.As is seen is the magician in Marselles and RWS based, the symbols as infinite is a lie down 8, but in this case is just the caduceus.
