Short update after the game:
I was able to stop the gremlin machine in turn 2. The snipers were indeed well worth their stones, as was Yin. I did not get much use out of Yamaziko, but that was not her fault but the War Pig's ;-). As she was my bodyguard model, I lost three points there, should have stuck it on Yin. The opponent had Bishop who caused a bit of mayhem as was expected.
In the end I lost 8:4, but next time I'll know what is waiting for me. Thanks again all around for the help. Greatly appreciated
