Rulings
10 official rulings, in the order Wizards published them.
- 2024-02-02
Each Case has two special keyword abilities: to solve and solved.
- 2024-02-02
Being 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.
- 2024-02-02
"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."
- 2024-02-02
"To Solve — [condition]" means "At the beginning of your end step, if [condition] and this Case is not solved, it becomes solved."
- 2024-02-02
The effect of Case of the Locked Hothouse that allows you to play an additional land is cumulative with similar effects. For example, if you control two Case of the Locked Hothouses, you'll be able to play three lands during each of your turns.
- 2024-02-02
The 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]."
- 2024-02-02
"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.
- 2024-02-02
Cases don't lose their other abilities when they become solved.
- 2024-02-02
"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]."
- 2024-02-02
Once a Case becomes solved, it stays solved until it leaves the battlefield.
