エンチャント
いずれかの対戦相手がそのプレイヤーのライブラリーを切り直すたび、あなたはそのライブラリーの一番上から2枚のカードを見てもよい。 あなたはそれらのカードのうち1枚を追放してもよい。 その後、残りをそのライブラリーの一番上に望む順番で置く。
In most cases, Green Sun’s Zenith instructs you to shuffle your library twice. Although shuffling that library only once is an acceptable shortcut, Psychic Surgery’s ability will still trigger twice.
You look at the top two cards of that library as the triggered ability resolves. That happens after your opponent is done shuffling.
If your opponent’s library has one card in it and they are instructed to shuffle that library, Psychic Surgery will trigger. You may’ exile the one card in that library.
