Card Trivia:Fool of Prophecy
- This card is based on the Tarot card, The Fool, of the Major Arcana and is numbered 0, 22, or unnumbered depending on the Tarot deck.
- This card's OCG name is from the French name for "The Fool", Le Mat.
- This card appears to transform into two "advanced forms" when combined with a "Spellbook": with "Spellbook of the Master" he becomes "Reaper of Prophecy", and with "Spellbook of Judgment" he becomes "World of Prophecy". These are two other "Key" Tarot cards whose numbers have extra meaning: 13 and 21, respectively.
