如果在其操控者的下一个重置步骤开始时，该目标生物已是未横置，则该异能的第二部分不会对其产生影响。
If a targeted creature is untapped at the time its controller's next untap step begins, the second part of the ability has no effect on it. -

如果受影响的生物在其原本操控者的下一个重置步骤之前就已改变操控者，则此异能会在其新任操控者的下一个重置步骤中防止它重置。
If an affected creature changes controllers before its previous controller's next untap step, this ability will prevent it from untapping during its new controller's next untap step. -

你可以指定任意两个（或更少）生物为目标。就算其中有已横置者也没关系。如果你支付{蓝}来施放永冻陷阱，则你不一定要指定在对手操控下进战场的绿色生物为目标。
You may target any two (or fewer) creatures. It's okay if any of them are already tapped. If you cast Permafrost Trap for {U}, you don't have to target the green creature that entered under an opponent's control.
