```text
Creatures you control have trample.
Whenever Triton, Poseidon's Herald attacks, you may tap up to three untapped lands you control. For each land tapped this way, create a tapped and attacking 4/4 blue Kraken creature token. Sacrifice those tokens at end of combat.
```

Art brief: Triton blows a single pale conch above the water. One broad crest behind him suggests a host taking shape, with a clean horizon.

Image 1 is FRAME/LAYOUT REFERENCE ONLY (aesi-cmr): match conventional modern M15 geometry, conventional gold with green and blue accents frame. Use the integrated legendary title crown. NO Nyx stars (not an enchantment creature). Replace every reference card datum, art, rules, set identity and credits. Image 2 is approved Clash support card P01: SET CONSISTENCY REFERENCE ONLY, painterly fantasy realism, type/rules typography and small lightning-bolt set mark; do not copy its art, card data, or green color where inapplicable.
Art only in the landscape art window: Triton blows a single pale conch above the water. One broad crest behind him suggests a host taking shape, with a clean horizon. Painterly fantasy realism, one clear narrative focal moment. The source's deliberate simple composition matters: no additional crowds, armies, architecture, particles, or needless detail. No text inside art.
Use Beleren-style title/type and Plantin-style rules serif. Pale quiet rules panel; literal left-aligned rules with natural line wrapping, enough room for all words.

## Observed visual QA

Passed. Exact name (typographic apostrophe), 2/G/U cost, Legendary Creature — Merfolk, 4/5. Both complete rule paragraphs checked word for word, especially may tap up to three untapped lands you control, for each land, tapped and attacking 4/4 blue Kraken creature token, sacrifice those tokens at end of combat. Gold green-blue legendary crown without Nyx, orange-red mythic bolt, oval, P10/footer. Clear single conch-blowing Triton and one broad wave crest.

Reviewed actual generated pixels, including each rule line and symbolic glyphs; no unresolved game-data or layout defects. Modest typographic apostrophe styling and sub-percent aspect-ratio variance are cosmetic.
