Mox Amber card art
Mox Amber is zero-mana acceleration that comes online the moment your commander hits the table — in the right deck, that's a free mana rock on turn one. The catch is hard: it produces nothing without a legendary creature or planeswalker already in play, so commanders like Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept (zero-mana to cast) or Teferi, Time Raveler make it immediately live, while slower or legendless builds should leave it on the shelf.

Commanders with the highest synergy

01
Rograkh, Son of RohgahhSilas Renn, Seeker Adept

Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept

93.3% of decks · synergy 0.88

Rograkh, Son of Rohgahh // Silas Renn, Seeker Adept costs zero mana, meaning Mox Amber is active before you spend a single land drop — that's the cleanest possible activation condition in the format, which is exactly why 93% of these decks run it.

02
Thrasios, Triton HeroYoshimaru, Ever Faithful

Thrasios, Triton Hero // Yoshimaru, Ever Faithful

86.5% of decks · synergy 0.83

Mox Amber slots into Thrasios, Triton Hero // Yoshimaru, Ever Faithful as part of the fast-mana package that powers turn-two or turn-three Thrasios activations, and Yoshimaru's one-mana cost means Amber is live in your opening hand.

03
Dargo, the ShipwreckerTymna the Weaver

Dargo, the Shipwrecker // Tymna the Weaver

70.8% of decks · synergy 0.67

Dargo, the Shipwrecker // Tymna the Weaver lists lean on artifacts and cheap permanents to reduce Dargo's cost, and Mox Amber does double duty — it's a free artifact that also taps for red or white the moment either commander is down.

04
Tevesh Szat, Doom of FoolsThrasios, Triton Hero

Tevesh Szat, Doom of Fools // Thrasios, Triton Hero

66.1% of decks · synergy 0.63

Tevesh Szat, Doom of Fools // Thrasios, Triton Hero is a cEDH staple running four colors, and Mox Amber provides free colored mana that would otherwise require a fetch or dual — with either commander in play it covers black or blue on demand.

05
Kinnan, Bonder Prodigy

Kinnan, Bonder Prodigy

67.0% of decks · synergy 0.61

Kinnan, Bonder Prodigy doubles the output of nonland mana sources, so Mox Amber goes from producing one mana to two the moment Kinnan is in play — a zero-cost rock that taps for two is exactly the kind of redundancy this deck wants.

In Commander, Mox Amber ranges from a staple to a blank depending entirely on your commander's cost — zero- and one-mana legendary commanders make it one of the best rocks in the format, while anything that costs three or more makes it a liability in your opening hand. Modern and Pioneer see it in niche legendary-creature shells, but the payoff is harder to assemble consistently without a command zone guarantee, so it shows up mainly in dedicated combo builds rather than fair decks. Legacy and Vintage have access to the full Mox cycle, which mostly pushes Mox Amber out of those formats except in builds specifically valuing colored mana off a legendary permanent. Oathbreaker is a natural home for the same reason as Commander — your planeswalker signature means Amber is always activatable — and that format's faster game speed makes free mana even more impactful.

Mox Amber doesn't have a current price in the data, so check Scryfall or your preferred retailer for the live number before buying. Historically it has tracked the demand from cEDH players and premium Commander builders, so expect it to carry a meaningful premium over a typical rare mana rock.
