Jan Jansen, Chaos Crafter + Haunted One + Retribution of the Ancients + Viscera Seer

Jan Jansen, Chaos Crafter

Haunted One

Retribution of the Ancients

Viscera Seer

How it works

1. Activate Jan Jansen's first ability by tapping it and sacrificing another artifact creature you control except the Gnome or Artificer.
2. Jan Jansen triggers, causing it and creatures you control that share a creature type with it to get +2/+0 and undying until end of turn.
3. Resolve the Jan Jansen ability, creating two Treasure tokens.
4. Activate Viscera Seer by sacrificing Jan Jansen.
5. When Jan Jansen dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
6. Resolve the Viscera Seer ability, causing you to scry 1.
7. Activate Jan Jansen's first ability by tapping it and sacrificing the Gnome or Artificer.
8. When the Gnome or Artificer dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
9. Resolve the Jan Jansen ability, creating two Treasure tokens.
10. Activate a Treasure by tapping and sacrificing it, adding .
11. Activate Retribution of the Ancients by paying and removing the +1/+1 counter from Jan Jansen and the other Gnome or Artificer, giving a creature -2/-2 until end of turn.
12. Repeat from step 4.

This clever loop uses Jan Jansen, Chaos Crafter as both your primary engine and your commander, leveraging Haunted One to grant your board undying the moment Jan Jansen becomes tapped to sacrifice an artifact creature. With Viscera Seer ready to sacrifice your creatures for a quick scry 1, you can intentionally send Jan Jansen and your other creatures to the graveyard to trigger their return with +1/+1 counters. Those generated Treasure tokens conveniently fund Retribution of the Ancients, allowing you to pay black mana and strip away those +1/+1 counters to shrink opposing creatures down to nothing while keeping your infinite sacrifice and token loop fully fueled.
