Hello ! I can't find precise information about the cards distribution. There is this frequency info on the bottom right, but is it just about the number, or also the color ?
And what about the spirals and cross ?
Thank you for your help !

Another tip is that the number of creatures on the card show the number of cards with that color and number.

Thank you for your answers, it's perfect ! (The detail and the tip top remember easily )
