In which situation is a time limit not applicable?

In the context of Magic: The Gathering tournaments, a situation where a time limit is not applicable typically refers to instances where the tournament structure allows for matches to continue until a winner is determined without the pressure of time constraints. Final matches are often considered "un-timed," meaning that players can take as much time as needed to resolve the match, allowing for a fair and thorough conclusion to a high-stakes game without the risk of running out of time. This practice ensures that players have the opportunity to fully engage with their strategies and make optimal plays during crucial moments of the tournament.

In contrast, individual events, quarterfinal matches, and Sealed Deck events typically have rounds that are timed to keep the tournament running smoothly and on schedule. Therefore, the absence of a time limit in final matches distinguishes them from these other types, where time constraints help manage the flow of the tournament.
