ソーサリー
プレイヤー1人を対象とする。あなたはカードを3枚引く。そのプレイヤーは、自分のライブラリーの一番上から3枚のカードを自分の墓地に置く。
Follow the instructions in the order listed on the card: if you target yourself, you'll draw three cards, then put the top three cards of your library into your graveyard.
If the target player is an illegal target when Thassa's Bounty tries to resolve, it won't resolve and none of its effects will happen. You won't draw three cards.
