Case File Auditor {2}{W}
Creature — Human Detective
When this creature enters and whenever you solve a Case, look at the top six cards of your library. You may reveal an enchantment card from among them and put it into your hand. Put the rest on the bottom of your library in a random order.
You may spend mana as though it were mana of any color to cast Case spells.

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.
