@Skabnoze Yes Teef Rukk is for extra artefact (I don't want to get rid of Mask, but wanted to try the Rockjaw) and extra command point. I never tried the ability, but seing some list at 6 Nation I saw a lot of monster, so hopefully the ability could trigger from time to time.
it's basicly the list I had in Vegas Open and that I had good success (and it's already painted), but i cannot fit the Gore Grunta anymore (cause the Arrowboys are now more expensive).
I'm hoping that the list will benefit from the Wyvern Waaagh ability and look out sir! to protect the small wizard will make up for the loss of extra wounds/body. The new command rule should help as well to protect Arrowboys/Big stabba reactively, meaning it should be easier to user Wurgog command ability.
I think the shakle fit really well in that list, specially agains High move army.
