## Immutable card specification

```json
{
  "id": "H03",
  "name": "Do Not Look Back",
  "mana_cost": "{W}{B}",
  "colors": [
    "W",
    "B"
  ],
  "type_line": "Instant",
  "rules_text": "Until your next turn, creatures you control with finality counters on them gain hexproof, indestructible, and “This creature can't block.”\nDraw a card.",
  "power": null,
  "toughness": null,
  "rarity": "rare",
  "replaces": "Anguished Unmaking",
  "primary_role": "answer",
  "signature": false,
  "myth_source": "https://www.theoi.com/Text/Apollodorus1.html",
  "myth_connection": "Apollodorus, Library 1.3.2, makes the return depend on Orpheus not turning around during the journey. Protection paired with inability to block is an explicit game metaphor: the returned may continue forward under protection, but may not turn back to defend home. The old attacker-exile clause is removed: the myth contains no invented pursuing monster.",
  "narrative_beat": "Protect a return by committing to the forward journey, accepting a vulnerable home front.",
  "design_note": "This is always an untargeted protection spell, and draws a card even if there are no marked creatures. The longer duration carries the protected company through a turn cycle, but prohibits blocking. This is useful before attacking and protects surviving returned engines through opponents' turns; it does not protect an unmarked Hades. The restriction does not remove an already-blocking creature from combat.",
  "signature_demo": null,
  "counterplay": "There are no targets: removing a marked creature cannot cause an all-targets-illegal failure. Opponents can attack around the protected company, use sacrifice or toughness reduction, or remove unmarked supporting creatures. The effect covers the creatures present with finality when it resolves, not later arrivals.",
  "art_brief": "Orpheus walks toward a small wedge of daylight with his face resolutely forward; Eurydice follows one step behind. Two figures and the light are the whole composition.",
  "tokens": []
}

## Actual prompt

```text
Use case: product-mockup / text-localization. Image1 is approved EDIT TARGET. Revise only the rules panel of this full Magic card. Preserve Orpheus facing resolutely toward daylight and Eurydice behind him, entire art/crop/ordinary WB gold frame, exact title Do Not Look Back, mana cost {W}{B} as sun/skull glyphs, Instant type, gold rare lightning bolt, oval, H03 and CLASH • CUSTOM • PLAYTEST footer. No crown, Nyx or P/T. High-resolution upright5:7 full visible borders. Replace ALL old rules with exactly these two paragraphs:
Until your next turn, creatures you control with finality counters on them gain hexproof, indestructible, and “This creature can't block.”

Draw a card.
The quotation marks around This creature can't block. are actual printed rules punctuation and must be included, with the period INSIDE the closing quote. No extra surrounding quotes. Keep upright Plantin-style serif and readable text with natural wrapping; no flavor, finality reminder, added words or rules. No target and no exile clause. This is one complete revised card face, not an isolated textbox.
```

## Observed visual QA

Passed exact WB, Instant and both rules paragraphs. Until your next turn; controlled creatures with finality counters gain hexproof, indestructible, and quoted This creature can't block ability; period inside closing quote; separate Draw a card. No target/exile clause. Gold ordinary nonlegendary WB frame, rare mark, no P/T/Nyx/crown. Orpheus looks forward while Eurydice follows. Footer H03 correct.

Dimensions: 1061 × 1482 pixels.
