Bind Arch Devil + Phoenix Pyre = fun

If you're looking for _funny_ devastating comboes, then the absolute funniest has to be -

(now guess, which combo could annihilate a ~400-strong invading army, half of them hoplites and hypaspists, the rest being mainly Vine Men/Ogres and Claymen, with some flagellants, shortbows and 2 elephants thrown in - when you only have 1 Lamia Queen, 9 Black Dryads, less than a dozen harpies and even less Manikins to defend your province? And I really mean annihilate: I have more fingers than I need to count the enemies who survived that battle)
