Riflemen + Mountain Giants + Basher. (Sometimes I add in the footman trainer, cata, healer, hawks)
Riflemen damage, and while units are targeting mountain giants are getting bashed.
Tauren + Healer + Riflemen + Hawk (Maybe abomination also)
Tauren and a healer are quite good but not OP. Reason being when they are healed, they last longer and have a more chance of reincarnation. Hawks are for picking off enemy damage dealers against the Tauren. Riflemen help out the front.
Ghoul + Necromancer + Corpse Wagon thing.
