  3. Resolve the Jan Jansen ability, creating two Treasure tokens.
  4. Activate Yahenni 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 Yahenni ability.
  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 {B}.
  11. Activate Retribution of the Ancients by paying {B} and removing the +1/+1 counter from Jan Jansen and the other Gnome or Artificer, giving a creature -2/-2 until end of turn.
