Preconditions​

  • P1 Main Phase

  • P1 has deployed The Erinyes (#026) — it is now on the field at lane 0

  • P1's familiar_deck contains "026_1" (Alecto), "026_2" (Megaera),

  • "026_3" (Tisiphone)

Action​

  • fire DEMON_DEPLOYED with source=The Erinyes
result = fire_event(state, event)

        # Erinyes must be removed from the field
        erinyes_on_field = [d for d in result.demons if d.unit_id == "026"]

Expected Postconditions​

  • The Erinyes (#026): REMOVED from field (it never truly enters play)

  • Alecto (026_1): deployed on field (lane 0)

  • Megaera (026_2): deployed on field (lane 1)

  • Tisiphone (026_3): deployed on field (lane 2)

  • "026_1", "026_2", "026_3" removed from P1's familiar_deck

  • "026" added to P1's graveyard
