Best Legion of Steel casters and Jack set up?

Fill the minimum jack points with jack and then use the rest to take as many iron fang as you can, so juggy and maraudeur are your friends. Don't waste your time with Torch with Strakhov, it's not worth it. Don't cut solos to bring more jacks, the list is already so much faster than the jacks that you're jack won't be doing much before turn 3 or 4, so don't worry about them. My current jack loadout with Strakhov2 is kodiak & juggernaut, but that will probably change when Sofya hits the table for chrismas.

I'm curious, why conquest with Irusk2, it doesn't benefit from energizer, so it will be lagging behind the rest of the army, I'd suggest taking double destroyers or one destroyer and one decimator and then with these points, go grab markov. Two tactician bubble is great and Markov with countercharge is really good.

I believe there are 2 best setups:

One is to have a Colossal on one flank and up to 3 units of fangs/uhlans with Markov (all your infantry stuff) on the other. Casters like Z1 or I1 are good with it. You get all fang synergy concenrated on crushing one flank (and it's easy to protect them all with clouds/diff terrain) while Colossal holds down other one (and you have a great upkeep for him in form of watcher/superiority).

Other is to have 2 fang units+Kovnik on one flank and Uhlans+Bears+Markov+Kovnik on the other and take 2 supporting jacks like Destroyer/Devastator/Kodiak/Demolisher/Decimator. Uhlans protected by countercharges are very hard to deal with. I2 is very good at this because he can have his own tactician bubble for those 2 fang units so Markov doesn't have to run around like crazy giving orders. Also Strakhov2 and Vlad2 because they can buff Uhlans enough to crush a flank.

Melee jacks are generally to be avoided, none of those casters like to use their focus for fueling and speeding up melee jacks. They want either to pour it into infantry like I1/I2/V2/S2 or sling spells like Z1.
Primary use for jacks should be shooting support away or making power attacks to set up targets for fang charges. Clams can trample/run for backline and start blowing up support.

Example lists would be:
(Irusk 1) Kommandant Irusk [+27]
- Conquest [37]
Iron Fang Kovnik [0(4)]
Uhlan Kovnik Markov [7]
Great Bears of the Gallowswood [9]
Iron Fang Pikemen (max) [15]
- Iron Fang Pikemen Officer & Standard [0(4)]
Iron Fang Pikemen (max) [15]
- Iron Fang Pikemen Officer & Standard [0(4)]
Iron Fang Pikemen (max) [15]
- Iron Fang Pikemen Officer & Standard [4]

Can drop Bears to switch fangs for  Black dragons or Uhlans or take mechanics, etc.

(Irusk 2) Supreme Kommandant Irusk [+27]
- Demolisher [16]
- Demolisher [16]
Iron Fang Kovnik [0(4)]
Iron Fang Kovnik [0(4)]
Uhlan Kovnik Markov [7]
Great Bears of the Gallowswood [9]
Iron Fang Pikemen (max) [15]
- Iron Fang Pikemen Officer & Standard [0(4)]
Iron Fang Pikemen (max) [15]
- Iron Fang Pikemen Officer & Standard [4]
Iron Fang Uhlans (max) [20]

Fangs are interchangeable with Black Dragons or even with more Uhlans with some solo/jack switching around.

Yup I know that, but how many target will the conquest really have when it's a spd 4 model in a melee army composed of spd 8 models, and spd 6 models with advance move. In my strakhov2 list I don't seem to have unengaged targets for long since the army is all melee and wants to go as deep as they can to get most work done.

I've never actually tryed the conquest in legion of steel so I might be overanalysing the theory here.

I'd need to try LoS with Irusk2 to test it, I've been runing it with Strakhov2 so far, and the jacks have been mostly useless so far. I was running with Kodiak Juggy, but they might get downgraded when Sofya comes out, if I downgrade the jacks and switch one of the black dragon unit for a regular unit I'm pretty sure I can get sofya without losing any of the countercharging solo that make the list what it is.

We have a Vlad3?
