Welcome to Librarium Online!
I'd quite like to paint up this list in the future, just using things I think are coo, l but does it suck?
I have only ever seen carnifex lists, either shooty ones or combat ones and never seem to see Hormagaunts.
10 Ymarl Genestealers
20 Genestealers w/ BroodLord
29 Hormagaunts w/ whatever gives them furious charge
2 Basic Carnifex
No, it's not weak, but it's also not a very strong list. It'll be better if you spit some of the squads into smaller squads like this:
10x Genestealers w/BL
15x Hormagants w/adrenal glands
14x Hormagants w/adrenal glands
But basically the model count is the same.
The main issue with it is the lack of any ranged AT. Your opponents can just play the keep-away game and keep on shooting. You should consider some hive guards or zoanthropes or putting some guns on your carnifex or tyrant.
