Great build! I would make only one minor change that is more preference than anything.

I would take out tribal tattoos and add Smash Der Beards. 

Tribal tattoos costs 0 which is always good, but I think Smash Der Beards will give to the extra attack boost needed to get their zone burning faster. 

Grimgore, Wyverns, Ironclaws, Rivr Trolls...doesn't quite sound "rush". Good build none the less.

 night goblins effect is forced you are going to destroy your own choppa/tribal tatoos

take a look at clan moulder elite, would be a nice to chage ironclaws for it
