Scenario was the radial one where you have to control the flag on your right and contest the far zone near your opponent's deployment.
So never having played this scenario, I could see how I could maybe tow some jacks toward the flag I needed to control, but there was no way I was going to get something else across to his zone to contest. I felt like I pretty much had to camp the flag he had to target and make him come to the brick.

The other thing I had told myself I didn't want to do this tourney was put karchev in the brick. The issue was, I had no good answer to pEiryss, and I was concerned that if karchev was well behind the brick, there wasn't much to protect him from her shooting around the (relatively small, even with clouds on the corners) front line of jacks. Even with the amount of push-pull, I felt like I'd have a better chance trying to keep the brick together with him in it.
I took second for the extra distance, to make sure I made it to the flag by turn 2 without too much trouble. He moved up uneventfully.
Karchev towed up, swapped to sidearms, the other jacks ran in either for free (zerker) or with the help of the koldun lord. Here was my first screwup, I saw the linear obstacle and thought oh, it'd be good for karchev to have some cover as backup... except that now his jack cant end movement there to plug the gap in the brick. Thankfully he at least had a greylord cloud on him.
I didn't see much point in shieldwalling the group of STs near the mages, since they would just pull them out before rolling damage anyway, so they ran up ahead of the brick to get in the way; the other group shieldwalled towards the far flag (although in retrospect, the MHA ignore shieldwall too anyway, so they should have run too.
He didn't want to risk eiryss trying to shoot through the gap against def19 (we rolled for whether karchev would get the cover since I was pretty sloppy about getting him within an inch, and came up no) so he backed her up. Feated and killed as many of the STs with battlemages as he could, he said afterwards that they were too tempting all spread out like that, so maybe that's a good bait for me... I'd rather trade a handful of STs for most feats, honestly.
sorry about the rotated images, need to figure out why the thumbnailing software is doing that, but too tired at the moment. I wish I had taken pictures every turn, because looking at this eiryss might have been in tow-alpha-strike range depending on how far back up the hill he had moved her, and one of his jacks almost certainly was.
As it was, I moved, bricked, and headlocked amongst the brick. I knew he could TK to beat it but was hoping def 15 would be enough to miss at least one. The STs sacced movement to stand back up and shoot, they killed several sentinels and one of the MHAs, but would have been better off running to foul up TK placement as much as possible, ditto for the mechaniks.
Anyway, he ran the arc node up, boosted all 3 TKs (not sure in restrospect why it was 3 boosted, since rahn's 8 focus, need to ask if I'm misremembering that or if it was only 2 tks; i had 2 headlocks but thought he needed a third to start getting a pull angle from the mages). Anyway, the brick was broken. Whip snap from the magister moved eiryss up, karchev got disrupted and charged by some sentinels. They only did 9 dmg thanks to some poor dmg rolls, which the mechaniks would end up fully healing next turn.

I felt like this was going to be a really lackluster feat turn without being able to cast, but I needed my jacks turned around the right way and doing something useful. First off, the greylords sprayed most of the sentinels to death, including all but one of the ones engaging karchev. I killed the remaining engaging one with karchev and feated; my opponent said he expected me to spray eiryss, but I would have needed 11 to hit (9 if I was able to powerbooster a jack to push karchev into aiming range, but I don't recall if that would have been possible). Even so, that would have been a better chance to take, I think - have the zerker or something kill the last sentinel first to clear engagement.
Couple jacks got charges on the arc node, couldnt get any more thanks to the flag, one trampled towards eiryss but was well short (and as my opponent pointed out, engaging her doesn't help, since he'll just TK), the last I was really frustrated with the placement of, considered failing a charge towards a sentinel just to get him in the way but vengeance would have moved him around anyway, ended up just pointlessly moving him up. Would have been better to trample to plug a bit of a gap.
Because I had charge issues due to not being able to end on the flag, I had stopped thinking about it as incorporeal, and misread the situation on that side. The phoenix was able to walk out of engagement with the juggernaut through the flag and into range of karchev, while only taking 1 free strike. He had rolled a 6 for field healing, and the free strike didn't crit, so no systems out and he took a big chunk off of karchev. TKed forward manticore finished the job; that one I flat didn't see and would have at least made a little more troublesome if I had done something useful with my last jack.
All in all, this is kinda what I wanted to get out of this tourney - one of the better players in the area, with a list thats a bad matchup for karchev, playing a scenario that's bad for him. Its one thing to know in the abstract that these are bad matchups, but I'm the kind of person that generally needs to play things out at least once to realize how bad they are.
At the time, I thought afterwards that I need to change up the list specifically to deal with eiryss (and pEiryss is MUCH worse for karchev than eEiryss), but in retrospect I'm not so sure. His tow threat range is comparable to hers, and there was at least one (probably two) times I could have taken a crack at her in this game.
