Strategies
With
While having below average stats for a 5 zombie, Foot Soldier Zombie's ability to hurt any plant or your opponent and possibly finishing them off is a very handy thing to have. Using this ability against plants that activate their abilities on zombies on their lanes, such as Potato Mine and Guacodile, can render them useless if there is no zombie currently occupying their lane. 3 damage is also enough to eliminate threats such as Sportacus, Mayflower, and Black-Eyed Pea.
However, Foot Soldier Zombie's ability only activates when they are played on a heights lane. Therefore, their usefulness varies on the number of heights lanes on the field; the more, the better.
Against
Foot Soldier Zombie can easily be destroyed using Whack-a-Zombie or any plant with 4 or more. You can lower their stats if you think you can handle them. If they get boosted, you can use Squash or Shamrocket to destroy them.
Since Foot Soldier Zombie's ability activates when they are played on the heights lane, try playing a powerful plant on the heights lane so the zombie hero is discouraged to play them there and activate their ability. Also, make sure they have at least 4 health to make an exchange at the very least. Another good idea is to use Sweet Potato, Hot Date, or Whipvine to move a zombie onto the heights lane, preventing Foot Soldier Zombie from being able to activate their ability.
