20 Neophytes with a Primus, given "a Chink in their Armor" enhancement is one of the hardest hitting combos in the entire roster. You start 20 man + primus in the reserves, wait for your opponent to come out of deployment then hit it hard.

It's so good. Mining lasers are too swingy for they hit on a 5+ but if you do hit, you get a bonus hit and you can always rerolls. If you're playing host of ascension the unit is a must.
A unit of 10 neophytes are also pretty good by themselves, you can sticky your home objective, spread them around if your opponent has any deepstrike to prevent them from taking your home objective etc.
You also get to make some epic gamer moves with your cult icon. Say you have a few dead models in your unit and you're barely outside of the range of an objective. You can revive the dead models in the range of the objective at the start of your command phase, and since scoring occurs at the end of the command phase, you can both bypass the battleshock step and score points. I've won a few games with this trick.
