Everyone says that defending against Orcs is difficult, but I disagree. In reality, "War Cry" – "Wrath of the Horde" – is much better than any destructive spell. Especially if you have a large army of Goblins! Also, when defending, you should place Goblins between some upgraded Cyclops and Sky Maidens. One group throws Goblins at the enemy, and the other, sacrificing them, attacks with a chain of lightning. Moreover, Orcs have Chieftains, and they can significantly speed up the movement of allies with their ability.
