クリーチャー１体を対象とする。ターン終了時まで、それは－４/－０の修整を受ける。
調査を行う。（「, このアーティファクトを生け贄に捧げる：カードを１枚引く。」を持つ無色の手掛かり・アーティファクト・トークンを１つ戦場に出す。）

Rulings:

• 4/8/2016 The token is named Clue and has the artifact subtype Clue. Clue isn’t a creature type.
• 4/8/2016 The tokens are normal artifacts. For example, they can be sacrificed to cast Angelic Purge or targeted by Root Out.
• 4/8/2016 If you sacrifice a Clue for another card’s cost or effect, such as that of Angelic Purge or Tamiyo’s Journal, you can’t also pay <img src="/Handlers/Image.ashx?size=small&amp;name=2&amp;type=symbol" alt="2" align="absbottom" /> and sacrifice it to draw a card.
• 4/8/2016 You can’t cast a spell without choosing legal targets. If all of those targets become illegal, the spell doesn’t resolve and you won’t investigate.
