What type of pairing algorithm is typically used in Magic tournaments?

In Magic tournaments, the most commonly used pairing algorithm is the Swiss system. This format allows for a series of rounds in which players are paired against others who have similar records, meaning that players who win the most matches face each other in subsequent rounds. The Swiss system accommodates a larger number of participants and ensures that each player has multiple opportunities to compete, unlike single-elimination formats where one loss can eliminate a player immediately.

This method allows for a more balanced and competitive environment, as it not only matches players based on their current performance but also provides enough rounds to give players a random chance to face opponents of differing skill levels. Since players are not eliminated after a loss, they can continue playing through the event, contributing to a more engaging tournament experience.
