Riddles in the Dark

Instant selection plus graveyard fuel is credible in blue midrange/control; it is less reliable than Stock Up but gains instant speed and concealment.

Could be wrong if If the face-down pile consistently lets opponents deny the useful cards, three mana is too slow for its modest card advantage.

A testable value spell for blue graveyard decks, but it is slower and less controlled than efficient selection; Accumulate Wisdom's 35 is a cautionary baseline.

Could be wrong if Pioneer graveyard and control decks may require cheaper, deterministic selection or direct discard outlets.

It can stock a graveyard while refilling, but Faithful Mending at two mana is a more direct graveyard setup tool and Modern punishes this tempo loss.

Could be wrong if A concealed-pile split could prove substantially stronger than expected in graveyard shells, enabling broader adoption.

Two cards plus milling at instant speed has a narrow graveyard-spell home, but it is far behind Legacy's one-mana Brainstorm, Ponder, and Consider rate.

Could be wrong if If its pile game reliably turns three mana into favorable selection and graveyard setup, Phoenix or control could retain it.

A reasonable instant-speed draw-and-mill spell for blue graveyard decks, though opponents choose and optimized Commander has stronger engines than this Fact or Fiction variant.

Could be wrong if Multiplayer politics and face-down information may make the choice more favorable than assumed, increasing its niche adoption.

At minimum it can split 2/2 to draw two at instant speed while filling the graveyard; strong card flow, though it does not affect the board.

Could be wrong if Unknown set speed and graveyard payoffs may make spending turn three without battlefield impact much worse than expected.
