Archaeomancer's Mapcard_draw$8.33Provides ongoing card advantage and resource smoothing in blue decks, especially when you keep recasting spells and leveraging the graveyard as a second hand. It is not a direct draw trigger, but it fills a similar value-engine role.
Mnemonic Delugecard_draw$5.17Rewards graveyard casting by letting you reuse spells from the graveyard for a huge burst of value. It is much more expensive, but it strongly overlaps with the recursive-spell game plan.
Underworld Breachutility$13.17While it is red, it is one of the closest functional cousins to Secrets of the Dead because it turns the graveyard into a casting zone. It enables repeated spell casting for massive value, albeit without the draw trigger.
Mission BriefingutilityBudget$0.31A cheap way to cast a spell from your graveyard while also improving card quality with surveil. It directly supports the same graveyard-casting gameplay and often effectively replaces a draw engine in spells decks.
Snapcaster Mageutility$17.19One of the best blue graveyard-recursion cards, giving flashback to a spell in your graveyard for immediate reuse. It is not an enchantment, but it plays the same role of converting graveyard spells into value.
Lier, Disciple of the Drownedutility$2.80A powerful blue payoff for graveyard casting that gives your instants and sorceries flashback. It is much more expensive, but it is among the strongest upgrades for spell-recursion shells.
Mystic RetrievalutilityBudget$0.32Straightforward spell recursion that lets you recast an instant or sorcery from the graveyard. It matches the same core game plan of turning the graveyard into extra cards and spells.
Sphinx's Tutelagecard_draw$6.23Another blue enchantment that provides repeated card-advantage style pressure in slower spell-heavy decks. It does not recur spells, but it occupies a similar enchantment-based blue engine slot.
