Audacious Swap 斗胆掉包
Casualty 2 (As you cast this spell, you may sacrifice a creature with power 2 or greater. When you do, copy this spell and you may choose a new target for the copy.)
The owner of target nonenchantment permanent shuffles it into their library, then exiles the top card of their library. If it's a land card, they put it onto the battlefield. Otherwise, they may cast it without paying its mana cost.
催命2
目标非结界永久物的拥有者将它洗入其牌库，然后放逐其牌库顶牌。如果它是地牌，则该牌手将它放进战场。若否，则他可以施放该牌，且不需支付其法术力费用。
催命2（于你施放此咒语时，你可以牺牲一个力量等于或大于2的生物。当你如此作时，复制此咒语，且你可以为该复制品选择新的目标。）

该咒语的复制品是在堆叠上产生，所以它并非被「施放」的。会因牌手施放咒语而触发的异能并不会触发。
The copy of the spell is created on the stack, so it's not “cast.” Abilities that trigger when a player casts a spell won't trigger. -

催命N意指「于你施放此咒语时，你可以牺牲一个力量等于或大于N的生物。」以及「当你施放此咒语时，若支付过其催命费用，则将其复制。如果该咒语具有目标，则你可以为该复制品选择新的目标。」
Casualty N means “As an additional cost to cast this spell, you may sacrifice a creature with power N or greater.” and “When you cast this spell, if a casualty cost was paid for it, copy it. If the spell has any targets, you may choose new targets for the copy.” -

支付某咒语的催命费用时，你只能牺牲一个生物，且也只能将该咒语复制一次。
You may sacrifice only one creature to pay a spell's casualty cost, and you copy the spell only once. -

如果你支付了某咒语的催命费用，则所成的复制品会比原版咒语先一步结算。
If you pay the casualty cost of a spell, the copy will resolve before the original spell.
