My friend and I mostly play 25 pt games since we dont have that many models yet and very limited time, as such I was trying to come up with a 25 pt list with eSorscha to battle his Circle forces. He usually brings Kromac with accompanying beasts or morghana with loads of infantry, mostly bloodtrackers. Anyway here is what I am thinking.
Max Winter Guard Infantry with UA and 2 rockets (10)
Great Bears (5)
Aiyana and Holt (4)
Kovnik Joe (2)
Changes I am thinking about making includes dropping a rocket to get Beast 09 instead of the spriggan, or replacing A&H with something else entirely, although I kind of like the idea of putting real dents in the circle beasts with the WGI. In any case the basic plan is to use the WGI as a screen for both A&H and the bears in order to bring them somewhat safely across the board, in case of mass infantry the sprays will come in handy and the spriggan can help with some of the stealth stuff with the flares. If the berserk stalker seems to be a big problem I can always call tough with Joe and take my chances on non-boosted shots with the WGI, probably paired up for the reroll from sorscha. All in all I think the list is pretty solid, but I would like it if someone could point out any flaws Im sure to have missed.
