To create your March Madness bracket with a mix of strong favorites, calculated upsets, and at least one dark horse team making a deep run, please follow these guidelines:

1. Strong Favorites: Select top-seeded teams that are expected to perform well throughout the tournament. For example, consider teams like Kansas, Duke, or Gonzaga.

2. Calculated Upsets: Identify lower-seeded teams that have the potential to upset higher-seeded teams based on recent performance or matchups. For instance, a 10-seed defeating a 7-seed.

3. Dark Horse Team: Choose a mid-tier seed (e.g., a 7, 8, or 9 seed) that has shown promise during the season and could make a surprising run to the later rounds. An example could be a team like Michigan State or Oregon.

4. Bracket Structure: Use a single-elimination format for the tournament, where each match eliminates one team until a champion is crowned.

5. Timeline: Ensure your bracket is set up to align with the tournament schedule, typically spanning over a few weeks in March and April.

By incorporating these elements, you can create a balanced and exciting March Madness bracket that reflects your preferences.
