  10. 10. THE RULES THE CR EDITION CR 103.1. At the start of a game, each player shuffles his or her deck so that the cards are in a random order. Each player may then shuffle or cut his or her opponents’ decks. The players’ decks become their libraries. CR 701.16a. To shuffle a library or a face-down pile of cards, randomize the cards within it so that no player knows their order.
  11. 11. THE RULES THE MTR EDITION Decks must be randomized at the start of every game and whenever an instruction requires it. Randomization is defined as bringing the deck to a state where no player can have any information regarding the order or position of cards in any portion of the deck. Pile shuffling alone is not sufficiently random. Once the deck is randomized, it must be presented to an opponent. By this action, players state that their decks are legal and randomized. […] the opponent must notify a judge.

  26. 26. CONCLUSIONS • Players are aware that cheating occurs • Players think it’s mostly done at the levels above wich they play • Players become more vigilant if they play for higher stakes
  27. 27. INTERESTING QUOTE “If I ever would want to play on professional level, the first thing I would learn is shuffle techniques, it’s what all pros use…”
  28. 28. THE CHEATS PERFORMED DURING SHUFFLING • Stacking the deck in a specific order • Stacking the deck for optimal sequencing • Loading a card in a specific spot while tutoring for another card • Loading an opening hand after an opponent shuffled the deck • Forcing an opponent into cutting/shuffling badly (by using force and jogged deck) • Substituting cards on hand (or even GY) with cards from the library • …
  29. 29. WHAT ARE OFTEN TELLS • “Please don’t shuffle my deck like that it’s bad for my cards” • A player shuffling excessively and with lots of flair • A player watching how his opponent shuffles in anticipation of his own shuffling • Players using the very same shuffling techniques every round in the same order • They use other techniques to shuffle the deck of their opponent • The player shuffles while keeping guard of his suroundings • Midround deckchecks with 5 copies of a card
  30. 30. THE 7 PRINCIPLES OF MAGIC
  31. 31. FALSE CUTTING
  32. 32. FALSE OVERHAND
  33. 33. FALSE RIFFLE
  34. 34. MY ADVICE • Monitor the false shuffler all day long (be very vigilant between rounds) • Use undercover judges • Look at his decklist and try to find what patterns he would be interested in. • Be even more vigilant if he uses cards that let him tutor • Do a casual deckcheck on the first game of the match • At the start monitor him, not the shuffling, you won’t pick it up anyway. • Try to speak with his past opponents in descretion
