  攻击和阻挡一经宣告，便不能利用威权高塔来撤销。如果想要阻止生物攻击，则最迟需要在战斗开始步骤的时候起动其异能；如果想要阻止生物阻挡，则最迟需要在宣告攻击者步骤中起动。

  Edifice of Authority can’t be used to undo an attack or block once it has been declared. Its abilities must be activated no later than the beginning of combat step to stop a creature from attacking, and no later than the declare attackers step to stop a creature from blocking.

  一旦牌手宣告起动某生物的异能，便无法利用威权高塔来撤销。威权高塔的最后一个异能必须在该牌手起动该生物的异能之前起动。该牌手可以回应威权高塔的异能来起动该目标生物的异能（如有）。

  Once a player has announced that they are activating the ability of a creature, Edifice of Authority can’t be used to undo it. Its last ability must be activated before the player activates that creature’s ability. The player may respond to Edifice of Authority’s ability with the target creature’s ability if able.

  起动式异能会包含冒号。通常会写成「[费用]：[效应]。」有些关键字异能也属于起动式异能；它们的规则提示中会包含冒号。触发式异能（以「当～」，「每当～」或「在～时」为开头）不受威权高塔最后一个异能的影响。特别一提，耗竭生物不属于起动式异能。

  Activated abilities contain a colon. They’re generally written “[Cost]: [Effect].” Some keyword abilities are activated abilities and will have colons in their reminder text. Triggered abilities (starting with “when,” “whenever,” or “at”) are unaffected by the last ability of Edifice of Authority. Notably, exerting a creature isn’t an activated ability.
