Case of the Crimson Pulse

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]."

If you have no cards in hand as Case of the Crimson Pulse's first ability resolves, you won't discard a card, but you will still draw two cards. Similarly, if you have no cards in hand when Case of the Crimson Pulse's last ability resolves, you won't discard any cards, but you'll still draw two cards.

"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 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]."

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