Imagine a vibrant and dynamic birthday card design that seamlessly combines the themes requested, with a style reminiscent of the bold and clean vector art seen in the works of artists like Malika Favre and Patrick Seymour.

**Background**:

A lively stadium backdrop sets the stage, its stands filled with stylized, colorful flat shapes to represent a cheering crowd. A clear, blue sky stretches above with a few flat, geometric clouds drifting lazily. In the center of the sky, subtly embedded within a cloud, the name "Mikael" is crisply etched in an elegant sans-serif font, providing a personal touch.

**Foreground**:

1. **Soccer Element**: A stylized representation of the Liverpool FC logo is subtly woven into the design on a large, flat-shaped banner unfurling from a soccer ball. The ball is situated at the bottom left, rendered in crisp black and white panels.

2. **Beer**: A large, gleaming vector-style beer mug with frothy foam overflowing sits prominently on the right side. The mug is a rich amber color with transparent layers to give it depth, casting a subtle shadow.

3. **Harness Racing & Betting**: In the mid-ground, a dynamic scene of harness racing is depicted with horses and drivers racing in silhouette, detailed with clean lines and vibrant shades of deep purple and electric blue. Nearby, a flat, bold depiction of a betting ticket floats in the air, colored in white with navy blue accents, suggesting the thrill of a wager.

4. **Small Dog**: A small, playful dog is portrayed in the lower center of the scene. It's a cheerful little caricature with flat shapes in shades of brown and beige, wearing a tiny red bandana around its neck, adding a touch of whimsy to the design.

5. **Birthday Cake & 50**: Dominating the center is an elegantly flat-rendered birthday cake, three-tiered, in hues of creamy whites and pastel pinks, adorned with geometric sprinkles. The top tier is adorned with the number "50" in bold, golden yellow, framed by minimalist flat candles in alternating colors of red and blue.

Each element is tied together with clean, sharp lines and flat colors, creating a cohesive and engaging scene that is rich with detail but uncluttered. The composition combines playful and elegant elements, with each component carefully balanced in the overall design.

Generated with these themes: Beer, Soccer, Liverpool FC, Harness racing, Betting, Small dog, Birthday cake, and 50.
