Brood Brothers are always a thing as well. Cheap good screens (and deaths for Unquestioning Loyalty.)
Minimum 5 man Acolytes are good coming out of reserve, our cheapest troop choice, can clean up a similar enemy unit, and is small enough to hide.
As you stated, Neophytes with Mining Lasers are viable. The Acolyte Hand Flamer bomb and Rock saw units with Icons are both competitve units that see play.
Really it is hard to go wrong with our troops (and units in general.)
