Marshal is the Fighting type elite 4 member in the games Black, White, Black 2 & White 2. Where his team consists of Throh, Sawk, Conkeldurr & Mienshao in both Black & White, as well as Black 2 & White 2. So overall, if you have a strong Flying type or Psychic type, you should be able to defeat his team pretty easily, just be wary as his team does carry some good coverage for Flying types, so Psychic type is best route to go, but even then still have to be wary a bit as some of his team have either bug type moves or dark type moves, definitely not an easy fight at all. However, Marshal is probably the Unova elite 4 member with the less memorable character design, and idk Marshal just isn't one I care much about, so that's ultimately why I chose to rank him out here.
