What should players be aware of in a Looking at Extra Cards situation?

In a Looking at Extra Cards situation, players should be aware of checking legally known cards before randomization. This is important because when a player looks at more cards than they are allowed, it can lead to an unfair advantage or knowledge that may influence their decisions during the game.

In this context, legally known cards refer to the cards in a player’s hand that their opponent is aware of, along with any face-up cards on the battlefield or in play. It's essential for players to understand what cards are legally known to maintain the integrity of the game and ensure that they do not accidentally use information they should not have access to when making strategic decisions.

Being aware of this aspect helps players avoid further complications from the infraction, as they can properly address what cards have been seen and ensure that randomization and other game processes are handled according to the rules. Other options do not align with the core understanding of this situation, focusing instead on actions that either are not relevant or would lead to unethical gameplay.
