Starlord-2814

Looking for some advice. I'm playing in a two list event at the end of August and have decided on anvil strike as my primary list. I'm having trouble with my secondary list. I feel like anvil strike is weak into ghoul spam and skaven but I am also worried into thricefold befoulment. I have done well with it into deepkin and slaanesh so I'm not worried about those match ups with anvil strike. I have considered running cleansing phalanx but have not been able to practice into those lists so it's just theory crafting at this point. Any advice is greatly appreciated.
