... no it doesn't? (This is a case of "the conclusion is correct, but the reasoning is wrong", the card does get shuffled into Agatha's deck, so you don't need to read the rest if you don't care about the reasoning) — Thatwasademo · 59 12/14/25

From You/Your - Expanded: "When resolving a triggered ability ... "you/your" refers to the investigator triggering the ability." So it clearly *would* be shuffled into the deck of the investigator spending the action to clear it. BUT, from Ownership and Control: "If a card would enter an out-of-play area that does not belong to the card's owner, the card is physically placed in its owner's equivalent out-of-play area instead. The card is considered to have entered its controller's out-of-play area, and only the physical placement of the card is adjusted." So the card is considered to be shuffled into the deck of the investigator who triggers the action, but is physically shuffled into Agatha's deck instead. — Thatwasademo · 59 12/14/25
