结界
每当一个由你操控的生物死去时,将它放逐。
在每个结束步骤开始时,若你未操控生物,则牺牲明日许诺,并将所有以它放逐的牌在你的操控下移回战场。
If you control more than one Promise of Tomorrow, each creature you control that dies will cause the triggered ability of each of them to trigger. Those abilities can be put on the stack in any order, and the first one to resolve is the one that exiles the creature card. That creature card will be exiled by that Promise of Tomorrow, and only that Promise of Tomorrow can return it.
