The way to beat CoT5: use Healing Wave, Freeze trap, Athena, Protection, Phoenix strike. Mermaid, succubus, goblins, centaurs, frozen giant, magic cannons. Use your Hero to kill of the Goblins, and then use all your SPELLS on the invis. Goblin, and protect on your own units, so he can't instant kill them. Keep it alive, it works...(Keeping alive DOES NOT mean SPAM it!)
A wonderful game, altrough (and I hate to say this) it is NOT at all like the Epic War 1 and 2, and i think you can improve it with a mode in which you might be able to use an archer in your tower (as in EW1,2).
