Converting artifact creatures into dual Treasure tokens and noncreature artifacts into Construct tokens establishes one of the most flexible artifact-sacrifice engines in the Commander format. On Moxfield’s high-power charts, Jan Jansen, Chaos Crafter from Commander Legends: Battle for Baldur’s Gate stands as a premier Mardu combo engine that seamlessly converts token generation into infinite untap loops and lethal ping damage.
As a 3/3 Gnome Artificer legend costing three mana (), Jan Jansen tap-activates to sacrifice an artifact creature and create two Treasure tokens, or sacrifice a noncreature artifact to create a 1/1 colorless Construct token. Paired with tap/untap synergy pieces like Clock of Omens, Thornbite Staff, or Dross Scorpion, Jan Jansen loops token creation infinitely to produce unbounded Treasures, infinite Construct armies, and immediate ping kills.
Here is the strategic operational blueprint of Moxfield’s premier Jan Jansen list, detailing how to abuse tap/untap triggers, cycle artifact tokens, and execute deterministic combos.
1. Core Mechanics & Strategic Phases
Succeeding with Jan Jansen requires fast Mardu mana acceleration, early artifact dorks, continuous untap enablers, and artifact ping payoff pieces.
-
Early Game (Turns 1–2): Deploy fast artifact mana like Sol Ring, Arcane Signet, and cheap artifact creatures like Ornithopter of Paradise. Cast Jan Jansen on turn 2 or 3.
-
Mid Game (Turns 3–4): Activate Jan Jansen to convert noncreature artifacts into Constructs or sacrifice Constructs for dual Treasures. Assemble untap engines like Clock of Omens or Liquimetal Torque.
-
Late Game (Turns 4+): Loop Jan Jansen using Clock of Omens or Thornbite Staff to create infinite Treasures and Constructs, draining the table instantly via Marionette Master or Disciple of the Vault.
2. Moxfield Highlights: Mardu Artifact Synergies & Untap Engines
The highest-rated community lists on Moxfield optimize Jan Jansen by fusing artifact token converters with tap-reduction mechanics and death-trigger pingers.
Clock of Omens / Liquimetal Torque
Infinite untap combo engine. Turning Jan Jansen into an artifact via Liquimetal Torque (or equipping specialized untap artifacts) allows Clock of Omens to repeatedly tap newly created Treasures and Constructs to untap Jan Jansen infinitely.
Marionette Master / Disciple of the Vault
Artifact death-trigger pingers. Sacrificing Treasures and artifact creatures triggers massive life loss across all opponents, weaponizing Jan Jansen’s token engine into direct damage.
Goblin Welder / Goblin Engineer
Graveyard artifact recursion. Allows you to tutor key untap combo pieces like Thornbite Staff or recover destroyed pieces directly to the battlefield.
Deflecting Swat / Silence
Mardu spell protection. Locks opponents out of casting interaction or redirects removal spells during your winning combo turn.
