If an opponent controls Ravenbloom Student and casts spells that trigger its might increase but doesn't announce the triggers, can they declare the increased might later when it becomes relevant (e.g., when targeted by removal)?

Ruling: Yes, the opponent has not missed the trigger until it has a visible effect on the game. They can declare the might increase when it becomes relevant, such as during combat damage or when targeted by removal.

Sequence:

• Ravenbloom Student triggers do not need to be announced immediately when spells are cast
• The trigger only needs to be demonstrated when it has a visible effect on the game state
• Visible effects include: taking lethal damage, dealing combat damage, or when the might value is otherwise required
• If the trigger is not announced by the time it would affect combat damage calculations or similar visible effects, then it is missed

Nuances:

• Players should ask their opponent about the unit's might before targeting it if they want clarity
• Attempting to catch an opponent in a missed trigger when you know they should have gained might is considered rule sharking
• Both players are responsible for maintaining proper game state
• Best practice is to announce all triggers as they happen for clarity, even though it's not required until they have visible impact
