This is a new hired sword that was inspired when playing WoL with the goblin herder.
Basicaly is a kind of goblin hunter with a wolf pet. It's a greenskins' exclusive hired sword, and the rules I wrote (in Spanish!) may be found here: http://frikidiario.blogspot.com/2011/07/espada-de-alquiler-montaraz-goblin.html
As you can see the wolf is a really old OOP Citadel mini.
