Art inside the landscape art window: Poseidon the Earth-Shaker looms above a storm-tossed Aegean coastline, tearing a vast rocky promontory away from the island with one powerful hand. His other hand holds a clear three-pronged bronze trident. The raw newly broken coast rises from the churning turquoise sea, suggesting his mythic tearing of Kos to bury Polybotes beneath Nisyros. A distant small ancient Greek sailing ship is driven backward by waves, emphasizing the god's immense scale and obstructed voyages. Poseidon has a powerful mature human form, long wet silver-dark beard, stern face, Greek draped cloth, subtle gold-bronze details. Painterly fantasy realism, dark storm clouds, sea-green depths, silver spray, warm light along the shattered stone. Coherent anatomy, readable trident silhouette and divine command. Keep all painting within the art window; no text or frame ornament inside painting.

Rules, preserve these paragraphs and three bullets:
You may play an additional land on each of your turns.

Fit the title on one line to the left of the mana cost. Italicize only the ability word Landfall, not the rest of the ability. Left-aligned legible black rules. Preserve every word including "hasn't been chosen this turn", "nonland", "an opponent", "owner's", and "additional". Do not insert ward, indestructible, devotion, reminder text, extra abilities or flavor. Readable conventional rules text size, with all three modes distinctly bulleted. No cropped borders or stat/footer collisions, no excessive ornate scrollwork, no art under the rules text.
