Jan Jansen, Chaos Crafter

Haunted One

Retribution of the Ancients

Bartolomé del Presidio

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 Bartolomé del Presidio 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 Bartolomé del Presidio ability, putting a +1/+1 counter on it.
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 cunning loop turns Jan Jansen, Chaos Crafter into a self-sacrificing engine fueled by Haunted One, which grants your commanders the undying ability whenever they tap. By cycling Jan Jansen in and out of the graveyard, you continuously generate Treasure tokens and death triggers. Bartolomé del Presidio provides a reliable sac outlet to bin Jan Jansen while growing itself with +1/+1 counters. Finally, Retribution of the Ancients uses the mana from the Treasures and the accumulated +1/+1 counters to clear away opposing creatures, letting the entire operation repeat indefinitely.
