What is the infraction when a player slows down play intentionally to run out the clock while losing?

The infraction related to intentionally slowing down play to run out the clock while losing is categorized as "Cheating - Stalling." This is because stalling is an intentional act of manipulating the pace of the game for an advantage, which directly violates the principles of fair play in Magic: The Gathering.

In this situation, a player who is behind in the game may try to prolong each turn deliberately, thereby potentially running out the time limit for the match. This behavior is detrimental to the integrity of the game, as it affects not only the individual game being played but also the overall tournament experience for all participants.

By designating this infraction as cheating, it highlights the seriousness of the action—indicating that such behavior is not just a minor offense or error, but a deliberate attempt to gain an unfair advantage by manipulating game mechanics.
