Archaeomancer's Mapcard_advantage$8.33Helps generate extra value from your graveyard and keeps cards flowing, though it does so through land advantage rather than spell recursion. It fits in the same blue value-oriented shell as a recurring engine piece.
Mystic Sanctuaryutility$4.05Rewards spell-heavy decks by turning graveyard interaction into more spell access, functioning as a recursive blue value land. It is a slower, land-based analogue to graveyard spell value.
Mission Briefingcard_advantageBudget$0.31Directly works with spells in the graveyard by surveilling and then giving a flashback-style effect. It is a close functional cousin for decks that want repeated spell use from the graveyard.
Snapcaster Magecard_advantage$17.19Turns a graveyard spell into a second cast and often generates card parity or advantage through tempo. It is one of the most efficient versions of the same graveyard-spell role.
Haughty Djinnutility$0.75Grows from instants and sorceries in the graveyard and helps keep a spell-based deck moving, though it is more of a payoff than a draw engine. It overlaps with graveyard-centric blue spell decks.
Teferi, Master of Timecard_advantage$7.82Provides repeatable graveyard setup through looting and supports spell recursion plans by smoothing draws. While not a direct replacement, it plays a similar value-game role in blue graveyard decks.
Lier, Disciple of the Drownedutility$2.80Lets you reuse spells from the graveyard and turns discarded cards into resources, which is the same broad game plan as Secrets of the Dead. It is a more powerful but more restrictive graveyard-spell engine.
Underworld Breachutility$13.17Enables casting spells from the graveyard repeatedly, which can trigger graveyard-cast payoffs and create explosive value. It is one of the strongest functional upgrades for graveyard spell decks, though in red rather than blue.
