裁定
The creature cards you exile are face up. Your opponent can see them while deciding whether to take one and which to take.
You may choose to exile only one creature card. If you do, the target opponent chooses who gets the card.
You may choose to exile no creature cards, even if there are one or more among the top ten cards of your library.
The cards that you look at but don’t exile never leave your library. They’re shuffled along with the rest of your library.
In a multiplayer game, you must choose the target opponent before you look at your top ten cards and decide what to exile.
