Which factor is NOT considered when determining the penalty for an infraction?

The factor that is not considered when determining the penalty for an infraction is the strength of the player's deck. In the context of the Magic: The Gathering Judge Infraction Procedure Guide, the focus is on the actions and behaviors of the player rather than the composition or power level of their deck.

When assessing penalties, judges consider elements such as the potential for abuse, which involves evaluating whether the infraction could be exploited further, and the amount of disruption caused, which refers to how much the infraction impacts the game state or the opponent's experience. Additionally, repeated offenses by the player indicate a pattern of behavior that can lead to harsher penalties.

However, the inherent strength of a player's deck has no direct bearing on the infraction itself or the appropriate response to it. This allows for a more fair and level playing environment, focusing on the integrity of the game and players' actions rather than the strategic choices they've made prior to the match.
