Jan Jansen, Chaos Crafter + Haunted One + Retribution of the Ancients + Phyrexian Altar

Jan Jansen, Chaos Crafter

Haunted One

Retribution of the Ancients

Phyrexian Altar

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 Phyrexian Altar by sacrificing Jan Jansen, adding .
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. Activate Jan Jansen's first ability by tapping it and sacrificing the Gnome or Artificer.
7. 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.
8. Resolve the Jan Jansen ability, creating two Treasure tokens.
9. 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.
10. Repeat from step 4.

This cunning loop transforms Jan Jansen, Chaos Crafter into a self-sustaining engine of creation and recursion, fueled entirely by the mana and sacrifice outlet provided by Phyrexian Altar. Whenever Jan Jansen taps to sacrifice an artifact creature, Haunted One triggers to generously grant undying and a power boost to your shared creature types, ensuring that tossing Jan Jansen or your Gnomes and Artificers into the Altar only brings them right back to the battlefield. Because those returning creatures arrive burdened with +1/+1 counters, Retribution of the Ancients steps in to neatly strip them away for a single black mana, resetting their undying potential while shrinking opposing creatures out of existence.
