Investigate

Investigate is a keyword action introduced in Shadows over Innistrad and reused in Innistrad: Midnight Hunt. It later became deciduous.
==Description==
To investigate, you create a Clue token. Clues are colorless artifacts, which have the ability ", Sacrifice this artifact: Draw a card."
Investigate sometimes is triggered when specific things happen. For example, lets you investigate when a land enters the battlefield under your control, and lets you investigate when a nontoken creature you control dies. Some cards also have abilities that trigger when a Clue is sacrificed. This makes the decision of when to sacrifice a Clue more interesting, and so in some cases sacrificing Clues as soon as possible is not necessarily the best play.
<c>Fae Offering</c> and from Modern Horizons 2 were the first cards to create Clue tokens without investigating (as these cards simultaneously create other predefined tokens along with Clues). As a consequence, the Clue token also became a predefined token. However, investigate won't be made obsolete.
Investigate and clue tokens are considered to be deciduous. It was a main mechanic for Murders at Karlov Manor where it was used in several ways (e.g. as a trigger, on spells, etc.).
