I finally got a test game in against some Plague Marines / Nurgle Deamons.
I took a list very similar to this, but some key changes. I dropped the Bomber and just decided to go with the Grot Bomb. I already have the models and it can be a fun unit. The unit tends to be underwhelming vs. his Plague Army as he generally runs at least three characters that can boost their weapons to insta kill them. I don't ever list craft so I just tried to use them as well as I could. The fact that I couldn't spam my venoms, raiders (i mention this a lot, but it makes me sad) made for a pretty interesting game, though.
The main difference was an Archon with WWP with the trueborn DS'ing with the raider, the Grot Bomb, and some gear stuff.
He took something along the lines of a huge unit of Chaos Beasts (the unit I hate the most), Sorcerer, Typhus, Another Hero with an insta kill weapon that allowed armor saves, Unit of Marines, flying thing with a battle canon, a few of the big Flies, a Maulerfiend, unit of six nurgle swarm bases, and probs some other stuff in there that I'm not remembering.
The only real plan I had was to try and be aggressive, hold his units up or give them incentive to not advance too far. If I let him, he can hop from cover to cover and push my units back easily enough while taking a lot of map control. I started with just the Talos, a Venom, and a unit of ten warriors with a DL in my deployment zone, everything else in reserves. Talos in the center, venom near them and the warriors in some rocks that I had.
The plan seemed to have worked, this time. The Talos / Venom on the middle - right side just kind of kept advancing, shooting each phase. As my reserves came in, I dropped my blasterborn near my opponents left flank, melting marines and weakening Typhus' unit. the WS came in and applied fire throughout the game on any right side unit (I was able to catch his swam bases out of cover one turn and pop most of them with the S6 guns). The Talos eventually charged the beast unit, insta killing a couple, finishing off a third with other wounds and contesting an objective the the last turn.
The Reavers came in eventually, helping to screen the unit I had holding the relic and causing some issues. The Grot Bomb just kind of got stuck in combat and eventually died out. He made the mistake of charging them with his flies and his Maulerfiend in one turn. The Mauler did well but I was able to kill off the flies with attacks to them. Eventually the bomb died after I killed the flies, and did a couple hull points to the fiend with haywire grenades. That was probably his biggest mistake, charging the flies in.
Eventually, at the end I was able to pull some typical DE shenanigans and hop on a bunch of objectives and pull out a minor win. The Spiders got quit lucky, dealing a Wound to Typhus on the last turn in combat (bringing him to one) and then he rolled a one to hit and killed himself...
