  一旦碎岩亚龙的触发式异能开始结算，则直到其完成结算之前，没有牌手能有所行动。特别一提，对手不能试图在你完成占卜，但还未展示牌库顶牌之前改变你的牌库。

  Once Sifter Wurm's triggered ability begins to resolve, no player may take other actions until it's done. Notably, opponents can't try to change your library after you scry but before you reveal the top card of your library.
