Reposting the modified plan from before:
DG1: Move forward to within 1" of the Executioners so they cannot wheel past. Move out of Executioner front arc, position for a flank/rear charge against Executioners next turn.
Steam Tank: Rumble 2 steam points towards the Spearmen Dark Riders and blast them with the steam gun.
ICK: Move forward, staying 14 15" away from the Spearmen bus. Rearrange characters in the unit so that the Lord cannot be in base contact with either Huss or the BSB. If Lord is in the center of the Spearmen, move Huss and BSB to the edges of ICK. If he is on one side or the other, move Huss and BSB to the opposite side of ICK.
Reiksguard: Charge Shades, redirect into Hydra if (when) they flee.
DG2: Charge Hydra.
Kn2: Charge Harpies, redirect to shades (if visible) Charge (now visible) fleeing shades, redirect into harpies.
Other considerations:
Magic: key spells are 5+ ward on the ICK, flaming attacks on the Reiksguard, and Iceshard the Spearmen.
Shooting: Steam gun on Spearmen, HBVG on the Dark Riders Spearmen to wipe them out.
