The card chosen was 3rd to the top. 'Six of diamonds magic' has the same amount of letters as 'ten of diamonds magic'. 'Six of diamonds magic' has 18 letters. Use 3 of the letters to get the chosen card at the bottom. A pack has 3 cards. You have 15 letters left. 15 is divisible by 3; the chosen card will come to the top.
