Hands down, I'd have to agree with everyone who has already stated that Neverborn are a tough matchup. I primarily play Kirai, but have had success with all the Resser masters.
My suggestions would include:
1. Fun list full of random models. With the largest pool of models to select from, you can make some zany crews that not only make things more interesting for you, but can also confuse your opponent.
2. Killjoy and or Jack daw automatically make things interesting for both sides. I've had a lot of success with both, and I've also had them cause me trouble, but fun all around.
3. against Collodi, I like Nicodem and a bunch of Punk Zombies because his blast damage and the punks abilities and resilience can lead to a lot of dead puppets.
4. GAKI are insatiable!!! Never underestimate the power of a bunch of low cost models in large group especially with a feeding frenzy trigger and a friendly kirai within 6"... Toss a couple corpse counters in and you have a recipe for invincible Gaki.
5. Crooked men in combination with Belles can be a nasty combo with the shafted markers and lure.
Hope these help/ add some fun to your games.
When you do get the chance, I highly suggest playing some neverborn to get experience. I've played almost every master in the game and I can tell you first hand that you learn so much about how to beat them by playing them.
Also the biggest lesson I've learned about ressers is that sinking points into big models isn't always the best idea. given 20ss i'd rather take 4 punks rather than Kill joy and Jack daw... but that applies to playing against any faction IMHO
