Case of the Crimson Pulse

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

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."

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.

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

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