For a total of 995 points and 4 commands points. The plan is to push for ward whit the army a screen all the characters whit the flocks. I plan to kill something squish first or second turn whit the solitaire for summoning the yncarne early in the battle and give FNP and fearless to my flocks. The farseer will cast doom on key unit for helping my poor S2. Whit that 80% of my army will be able to re-roll tohit and to wound. I am waiting for yours idea and sorry for the poor quality of my English this is not my native language.
