Pretty good, from what I can tell. you can use the stealth on the druids (since you have Kaya and the Overseer) and the shifting stones can help you teleport (if I remember how they work right).
I'll have a few different options for mine, but currently I have
Kreugar the Stormlord
Lord of the Feast
Gnarlhorn Satyr
2 Argus
Feral Warpwolf
Woldwatcher
And if I win two auctions on eBay, I'll have, in addition to above:
Woldwarden
6x Tharn Ravagers and 1x Shaman
I've been thinking of using Kreugar with the Woldwatcher and Woldwarden (both excel used with him), along with the Ravagers (if I win them of course). Whatever I do, I'll definitely be using the Lord of the Feast, as I really like his powers.
Anyhow, back to your list, definitely looks like a fun list!
