Narrative/art brief: Poseidon hurls one immense limestone island fragment downward; a tiny giant silhouette below establishes scale. Open sea and a spare storm sky. No crowd of combatants.

## Inspected references and roles

1. Approved edit target and art/set-style reference: `output/cards/custom/poseidon/P01-nisyros-falls.png`. Inspected before editing. Its previous rules have no authority over the revised source.
2. Real modern frame/layout reference only: `output/cards/custom-v2.1/batch-c/refs/urban-evolution-c19.png`. [Printing](https://scryfall.com/card/c19/205/urban-evolution?utm_source=api); provenance and original image URL in adjacent JSON. Inspected before use. No reference card data, illustration, watermark, credits or set symbol copied.

## Exact actual generation prompt

```text
Use case: product-mockup. Asset type: revised complete custom Magic card.
Image 1 is the APPROVED EDIT TARGET, Nisyros Falls. Image 2 is a REAL FRAME/LAYOUT REFERENCE ONLY (urban-evolution-c19); it provides modern M15 geometry and color treatment, never card data, art, credits, watermark or set symbol.
Change the green frame to conventional gold green-blue frame matching image 2 and the mana cost to {3}{G}{U}. Preserve the current painting of Poseidon moving a limestone island fragment and tiny Polybotes silhouette; it still depicts the approved myth. Replace ALL rules with the new complete text below.
Preserve flat approximately 5:7 portrait with complete black outer border, modern type and rules typography, landscape art window and pale rules panel. Use ordinary modern gold green-blue sorcery frame, with NO legendary crown. No Nyx texture. No legendary crown.
CURRENT IMMUTABLE CARD DATA (render verbatim except mana tokens become proper Magic glyphs):
Name: Nisyros Falls
Mana cost: {3}{G}{U}
Type: Sorcery
Rules, preserving paragraph breaks and bullets:
Create a token that's a copy of target land you control, except it's an 8/8 Elemental creature with trample in addition to its other types.
Return up to one target nonland permanent to its owner's hand.
Exile Nisyros Falls.
No power/toughness badge.
Rarity: mythic; small orange-red lightning-bolt set mark.
Footer: P01 and CLASH • CUSTOM • PLAYTEST; preserve centered bottom oval.
No flavor text, reminder text, artist credit, guild watermark or other new text. Do not print field labels or source braces. Preserve all restrictions, target words, timing and numbers. Keep all text legible and clear of symbols and stats. Art unchanged, no new background detail or characters. No perspective, tabletop, sleeves, lighting glare or drop shadow.
```

## Observed visual QA

Passed: exact 3/G/U mana glyphs, gold green-blue ordinary sorcery frame, all three revised paragraphs including target land you control, 8/8 Elemental with trample, in addition to its other types, up to one target nonland permanent, and self-exile. Mythic orange-red lightning, P01/footer, no P/T or crown. Original island-hurling scene preserved coherently.

All card lines, symbols, complete border and frame were read against the current source in the actual generated image. Typographic apostrophes are a cosmetic treatment. No unresolved rule, art or frame defect observed.
