I asked my informant if he had any rituals or practices for when he is playing Magic the Gathering, and he really needs to draw a certain card or cards. He says that he does not have any such practices, but that his friend does. His friend comes from Taiwan, and he says that in Taiwan, all the Magic players will knock on their deck when they are desperate for a card, like when the right draw is the difference between staying in the game or losing. Also if his girlfriend is around or any of his buddies are around, the player will get all these people to also knock on the deck. My informant says that if you believe in it, it increases your luck of drawing what you need. It’s similar to “believing in the heart of the cards” like in the show Yugioh. And when you do draw that card, you make a big, dramatic effort of unveiling the card.
I find it very intriguing that this informant says that the “knock on the deck” tradition is practiced by his Taiwanese friends, but my other informant on Top Decking rituals, who is American, also does this “knock on the deck” thing even though he has probably never heard of the Taiwanese folk belief.
