If a player orders some cards in his deck during a search and fails to randomize them afterward, what is this infraction?

The infraction being described is classified as cheating, specifically manipulation of game materials. When a player searches their deck and fails to randomize or shuffle it afterward, they create a situation where the information about the order of the cards is altered without the opponent's knowledge. This manipulation disrupts the fairness of the game and can potentially give the player an advantage by allowing them to predict or control what cards they will draw next.

In competitive play, ensuring that decks remain randomized after a search is crucial to maintaining the integrity of the game. Players are expected to act responsibly and follow the rules regarding deck searches and randomization. Failing to do so constitutes a serious breach of conduct, as it directly affects the game by manipulating the way game materials are presented and used. Other infractions listed do not accurately capture the essence of a failure to randomize, as they relate to different aspects of gameplay or player behavior.
