Input image 1 is REAL PRINTING FRAME/GEOMETRY REFERENCE ONLY: match conventional modern M15 gold multicolor geometry with R-W color accents, ordinary title bar, NO legendary crown and NO P/T badge. Replace all reference text, art, mana, watermarks and credits. No Nyx/starry treatment. Pale quiet rules panel, no watermark.
Input image 2 (approved Z08) is SET CONSISTENCY REFERENCE ONLY: match crisp typography, gold lightning rarity mark, footer, painterly fantasy realism. Its card data and palm artwork are irrelevant; do not copy them.
Typography: Beleren-style title/type and Plantin-style rules serif, precise black lettering, natural paragraph spacing. Title must fit in one line left of the ordered cost; entire type line must fit left of set mark. Keep all rules readable in conventional lower rules panel.
Art: Styx extending her hand in pledge toward Zeus over still black water, with a restrained silver reflection. The oath gesture carries the scene. Painterly fantasy realism. One focal narrative moment; coherent anatomy and objects. Only supporting details that serve the action. Confine painting to the landscape window. No lettering in painting.
