A player makes an error in one of the steps of the mulligan process. Once the mulligan process is complete and the game begins, excess cards arising from an improper mulligan is a Game Play Error — Hidden Card Error and too few cards is a Game Play Error — Game Rule Violation.
牌手再调度流程中的一步出现失误。一旦再调度流程完成并且游戏开始后，由于错误的再调度而产生额外牌张属于游戏行动失误～非公开牌张失误，而牌张过少则属于游戏行动失误～违反游戏规则。

Unintentional process errors that provide no advantage, such as declaring an intent to mulligan early or exiling too many cards to Serum Powder, are not an infraction.
流程上无意的失误如不会带来优势，例如提前表明再调度之意图，或使用浆液粉末放逐了太多牌，不属于违规。

A. A player draws eight cards at the start of the game (instead of seven).
A. 牌手在游戏开始的时候抓了八张牌（应为七张）。
B. A player chooses to not take a mulligan then takes a mulligan after seeing their opponent choose to take a mulligan.
B. 牌手先选择不进行再调度，后在看见对手再调度后也进行再调度。

Errors prior to the beginning of the game have a less disruptive option—a forced mulligan—that is not available at any other point during the game.
较之游戏中的其他时点，在游戏还没开始便发生的失误，还可以采用强制再调度这种影响较小的方式来修正，而其他时点就无法做到这点。

The player takes an additional mulligan.
牌手再额外进行一次再调度。
