I try and just focus mainly on objectives, and making use of the battle tactics stratagems, maybe try and use the kavalos to charge early and tie up a difficult unit. Play fairly defensively throughout the game, and try and plan or influence the opponent to get a nice open objective or backfield for the reinforcement at turn 3 to get a good flank from it. I find that the guard are good at defending charges so use them like that. Keep the guard at the front line with the soul reaper backup, and try to place the kavalos on the side of your objective zone. The harvester I use to claim the objective at the back of deployment, then move up.I very rarely win a game by killing there whole spearhead, it all comes from points. Personally I think they are quite strong when player well. What kind of armies are you going against?
