  "myth_source": "https://www.theoi.com/Ther/KuonKerberos.html",
  "myth_connection": "Hesiod, Theogony 767ff., describes the hound receiving arrivals while preventing unauthorized departure. Milling receives new inhabitants; returning one card to hand represents a chosen guest admitted back into reach under the host's authority. This second action is an explicit game adaptation, not an assertion that Cerberus freely resurrects the dead. Menace lets the host's permitted company advance behind the hound.",
  "narrative_beat": "The hound receives the growing host and accompanies a permitted company back toward the living.",
  "design_note": "Five mana immediately supplies six cards of graveyard fuel, recovers a creature to hand if available, and leaves a 5/5 menace body. Attacking repeats that finite-library value and grants the finality army evasion. Returning to hand spends mana to redeploy and does not reset any living creature's finality; there is no corpse-exile competition or incidental counter minigame.",
  "signature_demo": null,
  "counterplay": "Remove Cerberus before attackers are declared, answer the graveyard before its trigger resolves, or present two blockers. Removing Cerberus after its trigger has triggered does not stop milling or recovery. No target is chosen, so the trigger can recover a newly milled creature, but no player gets priority between milling and selection. The deck contains no sacrifice outlet that can loop Cerberus.",
  "art_brief": "Cerberus stands beside one arriving shade in the underworld entrance, one head watching the path outward. A large, clear three-headed hound; no army or elaborate architecture.",
  "tokens": []

## Actual prompt

```text
Use case: product-mockup / text-localization.
Image1 is APPROVED EDIT TARGET: complete custom Magic card Cerberus. Preserve the excellent coherent three-headed hound painting, crop and stone doorway, the monoblack conventional legendary frame and crown, exact title Cerberus, cost {3}{B}{B} as three ordered mana glyphs, type Legendary Creature — Dog, gold rare lightning mark, P/T 5/5, oval and H10 / CLASH • CUSTOM • PLAYTEST footer. No Nyx stars. Full upright5:7 card, entire border visible.
Replace the rules panel with EXACT three paragraphs:
Menace

Creatures you control with finality counters on them have menace.

Whenever Cerberus enters or attacks, mill six cards. Then you may return a creature card from your graveyard to your hand.
Exact replacement is important: enters OR attacks, SIX, MAY return, YOUR graveyard to YOUR HAND. No target, no exiling, no +1/+1 counters. Keep every other card element and art invariant. Plantin-style upright rules serif; readable complete rules, clear of5/5 badge and footer. No flavor, no finality or menace reminder, no extra text.
```

## Observed visual QA

Passed exact Cerberus, 3BB, Legendary Creature — Dog, 5/5. Menace; controlled finality creatures have menace; enters or attacks mills six then may return a creature card from your graveyard to hand. No target, exile or counter clause. Complete three paragraphs clear of badge. Black legendary frame, gold rare bolt, H10/footer. Existing coherent three-headed guardian art preserved.
