Mountain Climber is a zombie which behaves similarly like Drum Major that exchanges placement flexibility for the Bullseye trait. While the sacrifice is certainly considerable, Mountain Climber's lack of the dancing tribe makes her a strictly worse choice in Professor Brainstorm's dancing decks, as she does not benefit from the abilities of Aerobics Instructor and Flamenco Zombie unlike Drum Major does. Mountain Climber also does not work in a science deck.
However, unlike Drum Major, if you do play her on the heights lane, having 4 strength with Bullseye is usually better as she does 20% of the plant hero's health and prevents the plant hero from blocking. Additionally, it moves Mountain Climber out of range from Template:PvZHLink and Template:PvZHLink, making her very hard to remove. Combined with other dangerous zombies, you can stress the plant hero.
Still, because she is a sports zombie, she retains her usefulness in Rustbolt decks, and is able to be boosted by zombies such as Team Mascot and Zombie Coach like Drum Major can. Due to her trait, you may give her Lurch for Lunch to make her deal extra damage to the plant hero without filling the Block Meter.
Against
Mountain Climber will most likely be played on the heights lane, so prepare a plant to destroy this. Using tricks help with destroying this zombie. Beware of this zombie's Bullseye trait, as she will not fill the plant hero's Super-Block Meter. A quick counter to Mountain Climber is Skyshooter (assuming it was played on the heights lane), though it will die in the process, so try and use this with The Podfather so it can live. Also beware of Team Mascot, as he can boost Mountain Climber, and Zombie Coach, as Mountain Climber will then be immune to damage. If those don't work, using Template:PvZHLink or Template:PvZHLink also works, but beware that the latter can destroy your stronger defense.
