This puzzle is weird and random. Don't look for too much logic, just try things. Start by looking at the grey letters in the 5 main columns.
The black letters spell out the bad destiny: EIGHT DAYS HENCE DEATH WIELDS HIS SCYTHE AND POSSESSES YOUR SOUL. Ignore the black letters for the rest of this.
To get the good destiny, start with the grey T in the bottom right, and read up the columns from right to left. Skip the black letters and also the grey letters that are directly above/below tarot cards - these are the "twelve ignored". As you read these 55 grey letters, write them into the grey blanks, but skip the black blanks. The black blanks get filled in with a rearrangement of the 12 random letters in the tarot cards (the YF from the HERMIT for example) and also the 10 letters missing from the card names (the H from the HERMIT for example). If you do it all right, you get the good fortune:
THREE HEAVENLY BODIES CONFOUND DEATH AND HIS SCYTHE MISSES ITS MARK YOU WILL ENJOY LONG LIFE
