Another discovery on the web: doing magick with playing cards; i copy/paste most of it and made some adaptations

I establish a space that can remain up for at least a lunar month, and dress it with a red cloth upon which I place a votive candle on the South side, a small incense dish on the East side, and a dish of water with a sprig of rue on the West side. 
I remove all the courts from a deck of playing cards, and lay them out on the cloth in a ring, in the following order:

1 – K ♠, The Magister, in the North
2 – Q ♦, The May Queen, in the South
3 – K ♣, The Harvest King, in the West
4 – Q ♥, The Seeress, in the East
5 – K ♦, the Devouring Sun, in the Southwest
6 – Q ♠, Dame Fate, in the Northeast
7 – K♥, the Red Lord, in the Southeast
8 – Q ♣, The Reaping Wife, in the Northwest
9 – J ♦, The Dancer, between Dame Fate and The Seeress
10 – J ♠, The Man in Black, between The Devouring Sun and The Harvest King
11 – J ♥, The Merry Men, between The Red Lord and The May Queen
12 – J ♣, The Kern Baby, between The Reaping Wife and the Magister

Then, I choose three cards to represent what I Will to Be, and set them under the Joker, in the center. 
Doing this represents the mastery of witchcraft over circumstance. I light the candle in its holder and the incense in its dish. 
I take three pinches of salt, cast them into the dish of water, and proceed to conjure a small circle around the coven of cards with my right hand, asperging the circle with the sprig of rue and censing it with the incense. 
After the circle is made, I sprinkle and cense each of the Coven cards.
Then I take up the Joker and the cards beneath it and lay all but the Joker out in a line in the center, naming each of the three cards as I set it down.   
I point to each of the three cards with my right forefinger, touching the card as I state my intention. 

(paraphrase/adaption)
… (lay cards down) 1-2-3
…state intention 1-2-3, connecting the cards as in a storyline/sentence
…”And…(scoop up the cards in the sequence 3-2-1 with Joker on top of all)
…”by the power of witchery” (kiss the Joker)
…“it is mine, here and now.”  (Knock three times with my knuckles of my right hand  to the north of my stack)
…“So mote it be.”

Then I set the stack of cards in the center of the circle, set my Athame in the North, pointing at the stack of cards, and leave the assembly to keep going on its own.
Knocking three times draws the attention of the spirits I work with, so that They take note of what I’m saying and do Their part.
The Athame pointing to the stack reinforces my will working on the intention in the stack of cards.
The Coven of Cards will continue to work on the spell, keeping a current of energy going just like a battery, with the red and black acting as positive and negative poles.
I restate the spell every morning when I first wake, and every evening right before I retire.
I don’t repeat the circle casting, or the censing and asperging again, but in the mornings I do light a candle and some incense.
I leave the spell going until I see definite results or until a lunar cycle has completed, whichever comes first.
I keep a couple of decks of playing cards set aside for this kind of work.
One deck to take the Coven from, and a second deck because I often need a court card to represent the person I’m working for.
When I dismantle the spell, I put the three cards back in the deck they came from, then give offerings and thanks to the Coven of Cards before dispersing them back in their deck.
