Magnet-shroom

Overview
The Magnet-shroom steals anything metallic (like ladders, mining picks, jack-in-the-boxes, and buckets) from zombies, though it needs to recharge after doing so before it can steal anything else. Although it doesn't cause any damage,it will render some of the most difficult zombies nearly useless. It can take metal objects from about three plants away and from nearby lanes.

Strategy
Magnet-shrooms are great against small amounts of armor and tool wielding zombies. They do need to be close to the front row behind defenses to be in range of zombies, but remember that the Magnet-shroom is not the counter to every zombie, just zombies with metal objects. In addition, the pole-vaulting pole, zambonis, catapults, and clubs/road signs are not magnetic.
