I would say the two Legions it benefits most are DG and AL. You hit the nail on the head for DG; toss the Poxwalker on the Dark Apostle and use it each turn to get even tougher cultists. With AL, I'd consider buying more than the minimum number of Cultist squads; if you run this in the Insurgency Force detachment the cultists will come back on a 3+. Mix that with Infiltrating to start with and you have a ton of cheap, small, harassing units to tie things up with throughout the game while your marines grab objectives or eliminate targets.

Those are the ways that I've run it and had success in both. You might also go with NL and then the Dark Apostle will give the squad he joins Stealth ... but that doesn't seem as good as the other two, in my opinion.

As far as I know, they lose access to Shooting attacks and Running, so the only things worth buying are more dudes. Makes the base cost 305 or 325 with the Poxwalker Hive.

I believe if you take Typhus in one CAD, and the Alpha legion in another, you can infiltrate all the cultists AND they are all zombies because his ability is Armywide not restricted to his CAD.

That being said, I usually stay away from cultists because I play renagades

You certainly could. I mean, you have to figure over the course of a game that you won't be able to Pox every squad most times anyways. So, if you left 2-3 with just more dudes, then you could feasibly buy autoguns/flamers/stubbers on the fourth squad. I just wouldn't. Cultists aren't known for offense for a reason; I'd either buy more dudes to make squads harder to get rid of or spend the points elsewhere in the army where a gun upgrade goes further. (Extra, left over points are terrible to spend on a few Cultist upgrades, however.)
