Secrets of the Dead

The reward half of a flashback engine, built to make recursion pay double. On its own it does nothing; the price of having it in play is that your graveyard has to become the resource you most want to spend from. Pair it with cheap flashback spells and the math shifts: every spell you cast out of the bin replaces itself, so a yard full of recurrable cards turns a one-time dig into a self-fueling card-advantage loop. The trigger reads broadly. It cares about casting from the graveyard, not about flashback specifically, so anything that lets a spell be cast from there (escape, retrace, jump-start, disturb, and the like) feeds it just as well, which gives the card a longer shelf life than the keyword that birthed it. The tension is honest: the enchantment asks you to commit your deck to a graveyard-recursion plan before it earns anything, and it draws no card on resolution by itself. It sits inert until the bin fills, then snowballs the moment recursion comes online. Whether that asking price is worth paying depends less on the enchantment itself, which contributes no other relevant text, than on how many spells you can profitably replay around it.
