the new direction on the back should provide for some interesting deck fans!
Will you be repeating that line pattern on the front. where the lines go into the bleed?
Some magicians perform tricks that involve inverting a card in the middle of a pack without the spectator's knowledge. When doing so with a deck that's printed into the bleed but only on one side, especially if the pattern at the edge is a simple, non-repeating one such as this, will reveal an inverted card in the middle of the pack - it stands out, clearly noticeable.
The options to prevent this are to remove the print that goes into the bleed or to repeat the same pattern on the card fronts, being careful to insure that a card will look the same from the edge whether face-up or face-down. Alternately, you could use a small, repetitive pattern, something like the Bee Diamond Back or the Republic No. 02, to help camouflage it, though pulling it off requires a little more skill for the magician using the deck.
