With a taming/Mohsar pairing you are going to struggle into any match up with guns. Particularly Cygnar and Ret, but also potentially skorne.
I recommend dropping one of them for Baldur1, who can play very strong into a gunline.
Mohsar is super strong in this format, especially in Bones, because he has a versatile toolkit in that theme.
Thanks to crevasse and geomamcy you can play into infantry builds and be very safe in avoiding List chicken. With pillars, curse, the feat, and Sunhammer, you can also play strong into Jack/beast bricks. Pillars shut down any army with a lack of decent boostable shooting.
The key is to avoid guns like the plague, they are Moh’s greatest weakness.
That’s why you have baldur1, who can also be built in a well rounded fashioned. Either using earth spikes to control infantry or High Def targets, or using Stone strength and the feat to punch it out with Tanky armies.
Be very aware of grymkin. They destroy in this format. If you see dreamer in a beast build, try Mohsar, she has no good ways to ignore or remove pillars, and your fear can really shut her down. Mohsar is also really good at scalpling Grymlin swarms with crevasse.
She will probably pick the spell denial arcana, you want to burn that very early on as it can lose you the game in the mid to late game. All fall down will be really bad for Mohsar so be very careful with positioning him. Luckily all the wolds but the warden are immune to that arcana
I think Baldur1 + Mohsar is a strong combo in this format, but Baldur 1 And Tanith might work, I just think Tanith takes a lot of work to optimize.
