What are the Magic: The Gathering deck size rules and how do they impact gameplay?

In Magic: The Gathering, the deck size rule is a minimum of 60 cards. This impacts gameplay by requiring players to carefully choose their cards to create a balanced and effective deck. A larger deck can dilute the chances of drawing key cards, while a smaller deck can increase consistency but limit options. Ultimately, the deck size rule encourages strategic deck building and decision-making during gameplay.
