Bone Tower

The Bone Tower is one of the currently existing towers of the undead faction.

It's ability is to suck the enemies toward him and damaging them. The Bone Tower's pull also makes the enemies unable to attack too meaning that it would be useful against high damage low HP enemies. Sometimes against heroes such as the Old One when you use the ability he moves through your army but doesn't attack until pull has ended. The Bone Tower can also stun heroes like Fallout meaning its not bad to use it against him.
