So beleive it or not, there really are not that many auto-includes, and lists will vary greatly depending on caster.
For example I have 3 different lists I have been toying with for vindictus alone:
List 1:
conflictchamber.com/#c2201b_-0E1l2222mek9m03p3p2_lXlX2j2j2j[Vindictus 1] Vice Scrutator Vindictus [+29]
- Reckoner [16]
- Reckoner [16]
- Hierophant [3]
Exemplar Warder Elias Gade [0(5)]
High Exemplar Gravus [8]
Knights Exemplar Seneschal [0(5)]
Knights Exemplar Seneschal [0(5)]
Choir of Menoth (min) [4]
Exemplar Bastions (max) [15]
Exemplar Bastions (max) [15]
Knights Exemplar [9]
Knights Exemplar [9]
Knights Exemplar [9]
I played this a couple times, bastions were underwhelming, but vinny delivers them better than any other caster currently, and the list hits like a train while threatening an impressive 13" with the bastions.
List 2:
conflictchamber.com/#c2201b_-0E1l2222mek93plM9x2m2m2j2j2j[Vindictus 1] Vice Scrutator Vindictus [+29]
- Reckoner [16]
- Reckoner [16]
- Hierophant [0(3)]
Exemplar Warder Elias Gade [0(5)]
Knights Exemplar Seneschal [5]
Scrutator Potentate Severius [0(6)]
- Repenter [8]
Exemplar Errants (max) [16]
Exemplar Errants (max) [16]
Knights Exemplar [9]
Knights Exemplar [9]
Knights Exemplar [9]
No gravus, because I do not actually need desperate pace. Feat and errants alone should help me enough. Errants threat 17" with their bows, and they threat 10.5 inches in melee which is plenty for a jamming screen. Sevvy helps the list crack arm and def skew. Mat 8 and Pow 12-14 Knights E are bananas.
List 3:
conflictchamber.com/#c2201b_-0E1l2222mek9lM9x3BlZlSlZlS2j2j2jProtectorate Army - 75 / 75 points

Exemplar Cinerators (max) [13]

Have not tested this yet, but it seems legit. Cinerators under Dward should be really tough to shift, and at Pow 12 with eye, they should hit plenty hard enough as a frontline. SPD is fixed thanks to true path and Minifeat. I really want to test this out. I think I am gonna like this build the most and it is next on my testing trip.
Now these lists are mostly similar because I have a a particular goal for this in my pairing. They are mean to crack arm, but also do well into non magic gun-lines. Vindictus has the best delivery tech in faction, hands down. His feat is basically a time-walk and True path is the perfect spell for our exemplar. He can struggle into lists like Ossrum with all the jacks, but into most heavy skews or gunlines he will wreck face. (With a few exceptions like circle and minions who have lots of random tech that ignores the defensive tech vinny has) Even with this one caster, there is plenty diversity in unit choices, solo choices, and BG choices that you should have plenty of options.
As for other casters, keep in mind the toolkit and list, each has its own style of play. High reclaimer likes a combined arms approach, he also delivers the army fairly well into guns as long as they don't ignore clouds. Testament likes dudespam so probably want to stay away from bastions, though cinerators could work. Thyra can run a nasty brick breaker in EI, and likes tougher exemplar (see cinerators) and her army gets shot to pieces, but if you have a good gunline drop, she can wreck whatever the other list is. Even durst runs a nasty double cinerators build. Its slow as a dead cow, but there are ways to mitigate that. Arm 23 cincerators are pretty tough into guns.
What caster did you have in mind? FOr guns I think Durst, High reclaimer, and Vindictus are your best bets.
