Mox Jasper drops a free mana rock that taps for green, which in dragon-heavy shells like The Ur-Dragon means your five-color curve gets a zero-cost head start every game. The cost is a deck slot — but zero-mana ramp that never enters tapped earns it.
Best Commanders
Commanders with the highest synergy
The Ur-Dragon
The Ur-Dragon's nine-mana commander tax makes every free mana source matter, and Mox Jasper shows up in nearly 40% of lists precisely because shaving even one turn off that clock is meaningful. It enters on turn one without disrupting any other play, which is exactly what a greedy five-color dragon pile needs.
Lathliss, Dragon Queen
Lathliss, Dragon Queen wants to hit five mana as early as possible and then chain dragons to trigger her token generation, making Mox Jasper's free green pip a clean accelerant toward that gameplan. Every zero-cost rock brings the first dragon down a turn sooner.
Sivitri, Dragon Master
Sivitri, Dragon Master runs a tighter blue-black shell, but Mox Jasper still slots in as a no-cost artifact that speeds up the turn-three Sivitri and keeps her search trigger flowing ahead of schedule.
Ureni of the Unwritten
Ureni of the Unwritten churns through large creatures and wants as much mana available as early as possible to replay whatever she cheats onto the battlefield, so Mox Jasper's free entry and green pip slot naturally into that engine.
Miirym, Sentinel Wyrm
Miirym, Sentinel Wyrm rewards casting dragons early and often, and Mox Jasper accelerates toward the first dragon trigger without spending a turn on ramp — in a deck that doubles every nontoken dragon ETB, getting Miirym down a turn sooner compounds quickly.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | legal |
| standard | legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Mox Jasper is legal across Commander, Legacy, Modern, Pioneer, Standard, Vintage, and Oathbreaker, but Commander is where it actually sees play. In sixty-card formats, a zero-mana artifact that produces only one color of mana is too slow and too narrow to compete with the free spells those formats demand, and Vintage already has the Power Nine. Commander is the home because the format's singleton structure, higher average mana costs, and dragon-tribal density give Mox Jasper a context where free acceleration at any point in the game carries real weight. If you're not in a dragon deck or a shell that cares about artifacts, there are better rocks — but inside that archetype, it overperforms its zero mana cost.

unknown tier
Pricing data for Mox Jasper isn't currently available in the system, so check Scryfall or your preferred vendor for the live number. Given its near-40% inclusion rate in The Ur-Dragon lists and comparable penetration in other top dragon commanders, demand is consistent — if the price looks reasonable against other zero-mana rocks, it's worth picking up.
