The monkey PD is can one of the few that defeat a Black Hawk attack with only an investment of 1 gold.

The problem that most people have is that they don't realize that the monkeys get the best summons in the game. If you put a bunch of Gandarvas on the field with a good regen and maybe an Earth bless backed up by some of the Protection buffing spells you get(Wooden Warriors, Iron Warriors, Legions of Steel) and the MR buffs, and even the crazy buffs(ones that grant Luck, Etherealsness, or other powers), and you are unstoppable.

Combine basic magic with wicked troops, and you get armies that don't take losses from fights with armies. Only mages are to be feared, and even they don't do much.
