Wand of Illusion
This item is very useful. You can use it to create Illusions of dangerous units (like Mountain Giants) to make the enemy think you have more than you have. You can create Illusions of weak Heroes that the enemy might be after such as the Archmage. You can use Illusions to trick the enemy into chasing the Illusion rather than your real army. You can use an Illusion to attack an enemy town and maybe they will Teleport back to fight it not realizing it is a fake. You can also cast Illusions on allied units.

Wand of Illusion Counters
Dispel them. Usually if you think the enemy is doing something really stupid with their Hero or a unit, it's an Illusion. When the Illusion attacks something, select it and see if it's taking any damage. If it is not then you know it's a fake. Read more counters.
