A Smash crew with a wide variety of character mains
Generally speaking, most of the Smash crews are originally formed solely for the purpose of competing in tournaments together as well as crew battles. These crews also travel all over to compete, often having to rely on each other for housing, food, and other expenses. Also, winning a tournament while in a crew generally makes the entire crew look good, effectively increasing the entire group's popularity in the Smash community, regardless of the gap between individual player's skills. Another reason playing competitively in a crew rather than by oneself is beneficial is that it's possible to make combo videos for an entire crew, which can be useful in creating multiple videos without a large amount of footage per individual players.
