- If playing online, you may take notes of your opponent's cards. In real-life Duels, you may not. (This disparity is due to the nature of online play, as it's impossible to enforce note-taking: Online, you could screenshot the cards in your opponent's hand or write them down in a notepad, and nobody would be able to tell that you're note-taking).
