i found this strat to work quite well, this is only good for a 3v3 & 4v4... Mass necs with 5 grave yards in ur base and place grave yards just a lil ways away from ur opponents base. Mass up some necros and when in battle you will be by your grave yards for skellies, also have some obsidian statues to heal the necros mana. and Voila u have infinite skellies and towns are owned.:sly
