持續探查

Text:

每當由你操控的一個或數個生物對任一玩家造成戰鬥傷害時，探查。（將一個無色線索衍生神器放進戰場，且其具有「，犧牲此神器：抽一張牌。」）
，從你的墳墓場放逐一張生物牌：探查。你獲得2點生命。

Rulings:

• 4/8/2016 In a Two-Headed Giant game, if you control more than one creature that can attack, you may have them attack different opponents so that Ongoing Investigation’s first ability triggers twice.
• 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.
