What state-based action occurs if a player has no cards to draw?

When a player is required to draw a card and has no cards left in their library, state-based actions dictate that this player loses the game. This is a fundamental rule within the Magic: The Gathering game structure, specifically outlined in the Comprehensive Rules.

The concept hinges on the understanding that a player is expected to draw cards as a core part of gameplay, and if they cannot comply with this requirement due to an empty library, it triggers the state-based action of losing the game. This rule is crucial in maintaining balance and strategy within the game, as players must manage their resources carefully to avoid such a situation.

The other options do not align with the established rules governing game states. Continuing the game without any consequences would undermine the importance of managing one's library. Similarly, shuffling a graveyard into a library does not rectify the inability to draw, nor does skipping a turn provide a solution to the problem. Therefore, the correct identification of the action that occurs when a player has no cards to draw emphasizes the serious implications of library management in the game.
