I have been running a pre-boomsday control warlock in place of this deck. No skull involved. I can safely say that as of the last few days, it has proven to get the job done. If you haven’t yet crafted the skull and still want to play control, you can run something like this list. https://www.hearthstonetopdecks.com/decks/rin-condition/
I couldn’t find the original list I was basing mine on, so I just copied my list to topdecks
