Time to start setting up a trap for the Greatsword bus.
Charges:
Chariot charges the Outriders. If they flee, redirect into the knights.
BSB into the archers, redirect to wizard bunker.
Let the Chimera try to chase down the fleeing Outriders. If he catches them, reform to face towards the steam tank.
Movement:
I don't like the strategy of pivot-blocking the steam tank, but it's part of the rules, so go for it. He'll blow them away next turn anyway.
Depending on how the Chariot fares in the charge phase, either move WH1 up to block the knights or to divert the Halberds from flank charging our chariot.
Move the Warriors and Knights forward together, out of the steam tank's forward movement.
Get the Daemon Prince out of the forward line of the tank, to the other side of the snow drift.
Chase down the archers with the eastern war hounds and move the Chariot around the tower to support the center.
In hind sight, you could have charged the archers with the hounds, then redirected into the steam tank. He would have had to spend points to grind and we would have everything out of his forward arc, so no cannon shot. Same effect without pivot blocking. Then charge the archers with the BSB, possibly forcing them off the board, before redirecting into the bunker.
