High production is a given if you want to use the strategy I have outlined.

As for Ghoul Guardians, you buy them all the time, marching them up to your front fortresses to tie up the enemy while he attacks you as he sees you as an harmless turtle. At the same time you slowly grind away at him with your own army of summons and faster troops, building fortresses as you go along, stuffing them with those cheap defence troops. And if he attacks your main army you just fall back to your fortresses while you attack on another spot. Mobility and defence combined.
