Tactics for playing against Wizards.

Yes, this is a debatable issue. If there are many archers and they are protected, they can inflict significant damage. However, if it's an "Orc" unit, a couple of spells, and with the help of a "Wizard" hero, they can also destroy a good portion of the army. It's quite a debatable question, as it all depends on the hero, the artifacts, and the map.
