Timestream Navigator card art
Timestream Navigator hands you an extra turn for five mana — but only if you have ten or more lands in play and can bounce it back to your hand, conditions that make Riptide Laboratory nearly mandatory as a pairing. River Song and other Pirate-heavy builds hit those land counts naturally and recur the Navigator repeatedly, making this a legitimate late-game engine rather than a one-shot effect.

Best Commanders

Commanders with the highest synergy

01
River Song

River Song

63.4% of decks · synergy 0.62

River Song appears in over 63% of decks running Timestream Navigator because she draws extra cards off every opponent's spell, accelerating toward the ten-land threshold while the Navigator delivers the extra turns needed to close out games she's already pulling ahead in.

02
Admiral Brass, Unsinkable

Admiral Brass, Unsinkable

60.0% of decks · synergy 0.57

Admiral Brass, Unsinkable runs Timestream Navigator as the payoff for a wide Pirate board — Brass generates the board presence and incremental value that makes reaching ten lands realistic, and the Navigator converts that late-game mana advantage into additional combat steps.

03
Francisco, Fowl MarauderMalcolm, Keen-Eyed Navigator

Francisco, Fowl Marauder // Malcolm, Keen-Eyed Navigator

49.1% of decks · synergy 0.49

Francisco, Fowl Marauder // Malcolm, Keen-Eyed Navigator generates Treasure through combat, and Timestream Navigator turns each extra turn into another attack trigger, creating a self-reinforcing loop of mana production and additional combat phases.

04
Admiral Beckett Brass

Admiral Beckett Brass

34.9% of decks · synergy 0.31

Admiral Beckett Brass rewards repeated attacks with stolen permanents, and Timestream Navigator ensures those attack triggers keep coming — extra turns mean more stolen cards and more pressure before opponents can stabilize.

05
Inalla, Archmage Ritualist

Inalla, Archmage Ritualist

32.9% of decks · synergy 0.29

Inalla, Archmage Ritualist can eminence-copy Timestream Navigator on entry, creating a temporary token that activates alongside the original and doubles the extra-turn output before the copy disappears at end of turn.

Format Analysis

FormatVerdict
commander legal
legacy legal

standard not legal
vintage legal
pauper not legal
oathbreaker legal

Timestream Navigator is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but Commander is the only format where it sees meaningful play. In 60-card formats, reaching ten lands is a fantasy in most game states, and five mana for a conditional extra turn that requires bouncing the creature simply can't compete with faster, unconditional options. Commander's longer games, higher land counts, and Pirate-tribal synergies are exactly the conditions the Navigator is built for — it's a card designed by and for that format.

Price Context

Current price

$0.30 bulk tier

At $0.30, Timestream Navigator sits firmly in bulk territory despite its combo potential in Pirate decks, largely because its restrictive activation keeps it out of non-tribal lists. The price reflects real demand from dedicated Pirate builds, so don't expect it to drop further, but don't expect significant appreciation either.
