11 rulings from Wizards of the Coast
- 2 February 2024Cases don't lose their other abilities when they become solved.
- 2 February 2024Once a Case becomes solved, it stays solved until it leaves the battlefield.
- 2 February 2024The "to solve" ability of Case of the Gorgon's Kiss looks at what type the cards are after they move to the graveyard to determine whether the ability should trigger, regardless of any types they may have had before they were in the graveyard. For example, a creature card that has become a noncreature permanent will count toward the ability's condition when it's put into a graveyard. By contrast, a noncreature card that has become a creature on the battlefield will not count toward the ability's condition when it's put into a graveyard.
- 2 February 2024"To solve" abilities will check for their condition twice: once when the ability would trigger, and once when it resolves. If the condition isn't true at the beginning of your end step, the ability won't trigger at all. If the condition isn't true when the ability resolves, the Case won't become solved.
- 2 February 2024Tokens are not cards and, as such, do not count toward Case of the Gorgon's Kiss "to solve" ability.
- 2 February 2024"To Solve — [condition]" means "At the beginning of your end step, if [condition] and this Case is not solved, it becomes solved."
- 2 February 2024"Solved — [static ability]" means "As long as this Case is solved, [static ability]." Static abilities are written as statements, such as "Creatures you control get +1/+1" or "Instant and sorcery spells you cast cost {1} less to cast."
- 2 February 2024The meaning of "solved" differs based on what type of ability follows it. "Solved — [activated ability]" means "[Activated ability]. Activate only if this Case is solved." Activated abilities contain a colon. They're generally written "[Cost]: [Effect]."
- 2 February 2024Being solved is not part of a permanent's copiable values. A permanent that becomes a copy of a solved Case is not solved. A solved Case that somehow becomes a copy of a different Case stays solved.
- 2 February 2024Each Case has two special keyword abilities: to solve and solved.
- 2 February 2024"Solved — [Triggered ability]" means "[Triggered ability]. This ability triggers only if this Case is solved." Triggered abilities use the word "when," "whenever," or "at." They're often written as "[Trigger condition], [effect]."
