Which of the following actions reflects good communication between players?

Regularly checking the life totals aloud between players is a prime example of good communication. In a game of Magic: The Gathering, maintaining an accurate understanding of life totals is crucial for strategic decision-making. By confirming life totals verbally, both players can ensure transparency and mutual awareness of the game's state. This practice minimizes misunderstandings and can prevent disputes later in the match, fostering a more positive and respectful competitive environment.

Comparatively, the other options reflect poor communication practices. Ignoring discrepancies with card effects could lead to disputes and confusion, while feigning confusion disrupts the integrity of the match and could create an unpleasant atmosphere. Keeping plays hidden from the opponent is counterproductive to the spirit of the game, which emphasizes honesty and clarity in gameplay. Good communication not only enhances the resolution of the game but also supports a fair and enjoyable experience for both players.
