which troops to kill Baal?

[Holywhippet]

I still lost a fair number of troops, but my army of knights, emerald dragons, alcehmists, veteran orcs and horsemen managed to outdo the enemy in a straight slugfest. I figured ranged troops aren't worthwhile since you start off surrounded. Cast bless and dragon slayer at maximum level to make your troops do a lot of damage. Use soul draining to eliminate the largest enemy stacks.
