Whenever you cast your third spell each turn, this creature becomes prepared. (While it's prepared, you may cast a copy of its spell. Doing so unprepares it.)
Reports become test cases the matcher is graded against before an update ships.
Delvefall isn't a chatbot guessing, it compares the printed rules text of every card with plain math,
and examples like yours decide which differences should count.
