What happens if the game has not yet begun when too many cards are drawn?

In the scenario where the game has not yet begun and a player draws too many cards, the appropriate action is to shuffle the excess cards back into the deck and allow the player to continue with their mulligan. This approach maintains the integrity of the game and ensures that the player does not gain an unfair advantage from having extra cards. Mulligans are part of the initial game setup, and correcting the error by returning the extra cards to the deck allows for a fair start to the match.

The process emphasizes that, before the game officially starts, errors like drawing too many cards can be resolved in a way that resets the situation to a state that adheres to the starting conditions. This keeps the game fair and orderly, allowing players the opportunity to align their starting hands appropriately after the adjustments are made.

Other responses do not adequately address the established rules and procedures for handling a situation where too many cards are drawn prior to game commencement. For instance, placing the cards randomly on top of the library or resetting the game entirely does not align with the corrective measures highlighted in the rules. Similarly, issuing a warning is not warranted in this context since the player is still in the pre-game phase and can correct the error with a mulligan instead.
