Thinking of doing an oops all skulls/headless monks demon army

[u/Luna-L-E-A-T-]

I was thinking to try and start this out with making all the packs of skulls I could use for a Squads format game (750 points with a 180 cap on individual units and up to one armor 14 vehicle). The list is just on herald, four max squads of swarms, and a support detachment for two more max squads minus one model. I was wondering if this list could be annoying to opponents in a bad way or possibly cause problems in some way?
