Temporal Manipulationextra_turn$10.76A clean extra-turn spell in blue with the same core payoff: taking an extra turn. It is more expensive overall, but it skips the setup of requiring a permanent on-board engine.Time Warpextra_turn$14.53Classic blue extra-turn effect that directly mirrors the reward Timestream Navigator is trying to access. It is a spell instead of a repeatable creature source, but the functional role is the same.Capture of Jingzhouextra_turn$11.19Another direct extra-turn effect in blue, serving the same high-end turn-advantage role. It is a strict premium option compared to the creature-based engine.Walk the Aeonsextra_turn$1.36Provides extra turns in blue and can be bought back, giving repeated access like a reusable Timestream Navigator. The cost structure is different, but it fills the same role of recurring turn advantage.Nexus of Fateextra_turn$6.36A blue extra-turn spell that can recur itself, making it one of the closest functional replacements for repeated turn chaining. It is more expensive, but it offers inevitability without needing a creature to survive.Savor the Momentextra_turn$8.84Still grants an extra turn in blue, but with a drawback that can be mitigated in the right deck. It matches the same strategic goal of accelerating into more turns.Time Stretchextra_turn$2.86A much larger extra-turn payoff that serves the same ultimate game plan of chaining turns. It is not close on mana cost, but it is a direct upgrade in raw turn advantage.Beacon of Tomorrowsextra_turn$2.67A blue extra-turn spell that can shuffle back into the library, giving repeated access over a long game. It resembles Navigator’s reusable turn-doubling role, though at a much higher mana cost.
