Encroaching Mycosynth is the linchpin: it makes Treasures into artifact creatures, which means Skullclamp can kill them for two cards apiece and Dross Scorpion untaps Jan Jansen off every death. The loop feeds itself — Jan Jansen converts one Treasure into two Construct tokens, the Constructs die to Skullclamp, each death resets Jan Jansen, and the Treasure used to pay the equip cost is the only resource consumed per cycle.

Recipe

How it works

01

Prerequisites

You control an additional creature.

02

Steps

  1. Activate Jan Jansen's first ability by tapping it and sacrificing another artifact creature.
  2. When the creature dies, Dross Scorpion triggers, untapping Jan Jansen.
  3. Resolve the Jan Jansen ability, creating two Treasure artifact tokens.
  4. Activate Jan Jansen's second ability by tapping it and sacrificing a Treasure token, creating two 1/1 Construct artifact creature tokens.
  5. Activate a Treasure token by tapping and sacrificing it, adding {1}.
  6. Activate Skullclamp's equip ability by paying {1}, attaching it to a Construct token.
  7. The Construct dies as a state-based action due to having zero toughness.
  8. Skullclamp and Dross Scorpion trigger.
  9. Resolve the Skullclamp trigger, causing you to draw two cards.
  10. Resolve the Dross Scorpion trigger, untapping Jan Jansen.
  11. Repeat.

Result

Infinite card draw; Infinite draw triggers; Near-infinite death triggers; Near-infinite ETB; Near-infinite LTB

Variations

Cheaper, tighter, alternate lines

Blinkmoth Urn or a dense mana-rock base can replace the Treasure-as-mana step if the equip cost ever feels pinched. Any commander that runs Jan Jansen as the commander itself — typically a Breya, Etherium Shaper or Tymna the Weaver shell — wants Aetherflux Reservoir or Reckless Fireweaver as the closer once the library is empty, since infinite draw alone doesn't end the game.
