What is the infraction for a player who attempts to reverse another player's mana weaving by pile shuffling instead of calling a judge?

The appropriate infraction for a player who attempts to reverse another player's mana weaving by pile shuffling, instead of calling a judge, is classified as cheating, specifically cheating – fraud. This is because the act of manipulating the opponent’s card distribution or attempting to interfere with their strategies without proper authority undermines the integrity of the game.

Mana weaving is a practice that some players use to manipulate the order of their cards when drawing. When a player attempts to counteract this by rearranging their opponent’s cards, they are engaging in deceptive behavior to gain an advantage, which falls under the definition of cheating. The use of pile shuffling in this context is not a legitimate play but rather a tactic aimed at disrupting genuine gameplay, thus qualifying it not simply as an error in judgment but as an intentional act to deceive.

In competitive settings, the expectation is that players uphold the integrity of the match and resolve issues through appropriate channels, such as calling a judge, rather than taking matters into their own hands. This reinforces the importance of following proper procedures and maintaining fair play.
