What about this?
Death leaper assassins brood 380
- death leaper
- 5x 1 lictor
Flyrant 240
3x Mulcolids 45
20x hormagaunts 100 (use however 2 small squads one big one?)
Malanthrope 85
Zoanthrope w/ neurothrope 225
3x Mawlocs 420
This list would be good against infantry with light to medium armour the only unit here really capable of dealing with heavy armour would be the zoanthropes. The mawlocs would cause huge issues if the deep strike is a direct hit causing potentially 6 blasts which can then burrow next turn if they didn't mishap
malanthrope gives shrouded and synapse to gaunts while moving up the zoans are good for warp lance and leach life from the neurothrope
