Pylon Mine is the first ability for Pylon Mech. When used, it will drop a small Pylon Mine that explodes upon contact with a plant. The Pylon Mech can store up to four Pylon Mines at once.
The Pylon Mine is great for Gnome Bomb and Suburbination. It's a good idea to put Pylon Mines near the Graveyard to potentially blow up the Plant with the Gnome Bomb. And it's effective to place them near a capture point and is even more effective if placed near a capture point near the middle
