Alice and Nathan are playing in a Competitive REL tournament.
Alice mulligans to six cards but accidentally draws seven cards. Alice and Nathan agree to not to call a judge, and instead apply their own solution where Alice mulligans to five cards. After drawing her five cards, Alice has a change of heart. She calls a judge to get an official ruling.
If Alice had called a judge before applying the solution she and Nathan agreed to, then the judge would have applied the remedy described in the Infraction Procedure Guide.
If the player has too many cards in hand, he or she may choose to reveal his or her hand, and his or her opponent chooses a card from it to be shuffled back into the library. If more than one excess card was drawn (for example, eight cards drawn during a mulligan to 6) his or her opponent continues removing cards until the correct number has been reached.
If cards are not removed from the hand this way (either due to an error that didn’t lead to too many cards, or by the player choosing not to reveal), that player takes an additional mulligan.
Players may continue taking mulligans after the remedy has been completed.
Should a judge fix or partially fix a solution that was implemented by the players, or should the judge let the situation stand?
