What is a violation of the integrity clause that could lead to disqualification?

Using deceptive practices that could alter match outcomes is a clear violation of the integrity clause, as it undermines the fairness and honest competition that is essential to Magic: The Gathering tournaments. Integrity in a tournament setting means that all players must engage in the game with honesty and without manipulation of the rules or the game state for personal gain. Engaging in deceptive practices not only affects the individual match but can also impact the overall integrity of the tournament, potentially leading to an unfair advantage.

In contrast, seeking help with card choices, taking breaks between rounds, or inquiring about opponents' decks are within acceptable limits of player interaction and do not inherently compromise the integrity of the game. Players often discuss strategies and experiences during tournaments, and both taking breaks and seeking information about decks align with the expected social dynamics of the competitive environment. These actions do not manipulate the outcome of matches in an unethical way, making them acceptable behaviors in the context of the integrity clause.
