What should a player state if they want to proxy a card during a tournament?

When a player wishes to proxy a card during a tournament, it is essential for them to provide a reason for using a proxy. This requirement serves to ensure clarity and transparency concerning their intention to use a card that they do not physically possess. It enables the tournament organizers and opponents to understand the player's situation, which may stem from a lost card, a misordered deck, or other reasons.

By providing a reason, the player complies with a key aspect of tournament policy that prioritizes honest communication and fair play. It helps maintain the integrity of the game and facilitates a smoother process for both the player and their opponent. This practice also aligns with the expectations set forth in the tournament's rules, where the use of proxies is often regulated to prevent abuse and to protect the experience of all participants.
