Wait- why salamangreat sanctuary is in Gore deck?
I farm him using Gravekeepers. The cheap version only using 1 necrovalley but you also need commandant to search it asap. Fusion summon supernaturalist using the effect of spiritualist. Search hidden temple asap with it so he won't be able to summon link monster or activate the 1st effect of gouki suprex. Summon GK shaman to stop gouki GY effects to add other gouki monster from deck as well.
