What is the remedy for Looking at Extra Cards?

The appropriate remedy for the infraction of Looking at Extra Cards is to shuffle the library and remove non-random parts. This is in line with the Infraction Procedure Guide that aims to address the integrity of the game and restore fairness when a player inadvertently looks at more cards than they should.

When a player accesses more cards than allowed, it can lead to an unfair advantage, as they may gain knowledge that can impact their strategic decisions. To counteract this, the game requires that any extra viewed cards be treated in a way that helps maintain the random nature of the game. Shuffling the library helps ensure that any information gained from seeing those cards is nullified, thus preserving the game's integrity while giving the affected player a chance to continue without disadvantage.

The emphasis on removing non-random parts also pertains to the fairness aspect, as it ensures that no aspects of the game state are artificially influenced by the extra information gleaned from those cards. Other options do not effectively address the core issue of maintaining fairness and randomness in the game.
