非生物永久物变成生物后，除非其操控者在他最近的一回合开始时便持续操控它，它才能攻击，其{横置}异能也才可以起动。该永久物成为生物的时间长短并不重要。
A noncreature permanent that turns into a creature can attack, and its {T} abilities can be activated, only if its controller has continuously controlled that permanent since the beginning of their most recent turn. It doesn't matter how long the permanent has been a creature. -

就算该咒语被反击，它也会变成生物。
It changes into a creature even if the spell is countered. -

当它变成生物时，它不再是结界。
When it turns into a creature, it is no longer an enchantment. -

此异能是在施放咒语时触发，因此它会在该咒语结算前就成为生物。对于会在进战场时消灭结界的生物而言，无法利用此类生物来消灭此牌，因为当此类生物进战场时，此牌已不再是结界。
It triggers when the spell is cast, so it becomes a creature before the spell resolves. A creature that would destroy an enchantment when it enters can't be used to destroy this card, since it will no longer be an enchantment when the creature enters. -

“生物咒语”是指具有生物此类别的咒语，即使它同时具有神器或结界等其他类别也是如此。旧版的召唤类别也属于生物咒语。
A "creature spell" is any spell with the type Creature, even if it has other types such as Artifact or Enchantment. Older cards of type Summon are also Creature spells.
