Case of the Shifting Visage

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

“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.

If the spell that’s copied has an X whose value was determined as it was cast, the copy has the same value of X.

You can’t choose to pay any additional costs for a copied spell. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.

If a permanent spell is copied, it’s put onto the battlefield as a token as the spell resolves rather than putting the copy of the spell onto the battlefield. The rules that apply to a permanent spell becoming a permanent apply to a copy of a spell becoming a token.

“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.”

The copy is created on the stack, so it’s not “cast.” Creating the copy won’t cause abilities that trigger when a player casts a spell to trigger.

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].”

Each Case has two special keyword abilities: to solve and solved.

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.

The triggered ability Case of the Shifting Visage has when it’s solved and the copy it creates will resolve before the spell that caused the ability to trigger.

Cases don’t lose their other abilities when they become solved.

“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].”

Any choices made when the spell resolves won’t have been made yet when it’s copied. Any such choices will be made separately when the copy resolves.

The token that a resolving copy of a permanent spell becomes isn’t “created” and won’t interact with abilities that care about tokens being created, such as that of Case of the Pilfered Proof.

Once a Case becomes solved, it stays solved until it leaves the battlefield.
