Engineer
The engineer makes torrent's that attack plants that it can find but is easily killed but when there's about 3 then the plants usually dies. The engineer can build a teleporter that teleport zombies closer to the garden so they don't have to walk so far and the engineer gets 10 coins every times a zombie uses it. The engineer uses a jackhammer and moves faster and jumps higher to get close to enemies or get away from enemies, the engineer can deploy a drone that shoots plants and uses a cone attack. The engineer can throw a microphone that knocks out any nearby plants that are near where it hits and then the engineer can shoot them but they can't shoot back.
