Visualize a vibrant and whimsical birthday greeting card featuring a flat vector style, with a color palette that harmonizes vibrant reds, blues, and metallic silvers, creating a striking contrast against a soft pastel background.

**Central Scene:**

At the heart of the card, a robust war hammer stands prominently. The war hammer is intricately designed, with a handle adorned in spiraling geometric patterns, combining hues of deep blue and metallic silver. The head of the hammer glistens with a polished silver finish, adorned with stylized etchings reminiscent of ancient runes.

**Foreground Elements:**

A playful, tiered birthday cake sits prominently beside the war hammer, its surface smooth and matte, colored in soft pastel blues and pinks. Each tier is decorated with flat, vector-style candles emitting small, flickering flames. Across the top tier, the name "Paul" is crisply inscribed in bold, blocky letters, mimicking the angular design of the war hammer's etchings.

**Background Elements:**

The background is a soft pastel gradient, transitioning from a serene sky blue at the top to a gentle pink near the bottom, creating a warm, inviting atmosphere. Stylized clouds, crafted from flat, overlapping shapes, float lightly across the top of the card, each outlined with crisp, bold lines.

**Additional Details:**

A scattered arrangement of confetti-like elements in the form of small, flat stars and diamond shapes, in colors of red, blue, and silver, cascades across the scene, adding a celebratory feel. In the lower corner, a small banner unfurls, its surface appearing as if crafted from folded paper, carrying the simple message, "Happy Birthday," in sleek, vector-style text.

**Overall Composition:**

The design maintains a harmonious balance of whimsical and bold elements, using crisp lines and flat shapes to create a modern, clean aesthetic that captures the playful spirit of a birthday celebration infused with the epic grandeur of a war hammer theme.
