Outside of these two heroes, however, you might be inclined to replace him with other zombies, as Drum Major is, at best, a mediocre fighter without support from allies, like Vanilla.
Against[]
Try to use powerful plants or stall with weak plants to destroy this zombie. Using tricks will also aid the plant hero in destroying this zombie. If your opponent is Rustbolt, beware the combination of Drum Major and Team Mascot.
If this happens, get rid of Team Mascot immediately, or try to go after Drum Major. This also includes when you are going against Professor Brainstorm, as he can use Aerobics Instructor and Flamenco Zombie to let Drum Major do severe damage.
