Now this question might sound stupid, but I'm confused. Is there a difference between the Bicycle Maiden Back Marked Cards and Penguin Magic Marked Cards? I mean both are selling at almost the same price on the Penguin Magic website. If there is can you help me with: 1. Which one is easier to read? 2. Which one has a more hidden marking system? 3. Any additional bonuses to the decks (Double Backers, Blank Cards, etc) I believe that both come in mnemonica. Please help out!!
