719. Case Cards

In short

Case enchantments (Murders at Karlov Manor): have a "to solve" condition — at the beginning of the end step the game checks whether it's met, then the Case counts as "solved" and the solved ability becomes active. Once solved, stays solved.

Informal summary — the official English text below is authoritative.

719.1.Each Case card’s illustration is vertically oriented on the left side of the card, and its type line is along the bottom of the card.

719.2.The Case frame has no additional rules meaning.

719.3.Case cards have two special keyword abilities that appear before a long dash and represent a triggered ability and an ability that may be static, triggered, or activated.

719.3a“To solve — [Condition]” means “At the beginning of your end step, if [condition] and this Case is not solved, this Case becomes solved.”

719.3bSolved is a designation a permanent can have. It has no rules meaning other than to act as a marker that spells and abilities can identify. Once a permanent becomes solved, it stays solved until it leaves the battlefield. The solved designation is neither an ability nor part of the permanent’s copiable values.

719.3cIf a Case has the solved designation, “Solved — [Ability text]” is an ability that may affect the game if it’s a static ability, it may trigger if it’s a triggered ability, and it can be activated if it’s an activated ability. See rule 702.169, “Solved.”
