Demonstrate (When you cast this spell, you may copy it. If you do, choose an opponent to also copy it. Players may choose new targets for their copies.)

Destroy target artifact or creature you don't control. If that permanent is destroyed this way, its controller exiles cards from the top of their library until they exile a nonland card, then they may cast that card without paying its mana cost.

示范（当你施放此咒语时，你可以将其复制。若你如此作，则其选择一位对手一同复制。牌手可以为各自的复制品选择新的目标。）

消灭目标不由你操控的神器或生物。如果以此法消灭该永久物，则其操控者从其牌库顶开始放逐牌，直到其放逐一张非地牌为止，然后该牌手可以施放该牌，且不需支付其法术力费用。
