The Dread Elves often use a mixed arms approach. That means a mixture of short and long range shooting with different combat elements and magic support. They can also focus on a main infantry unit, supporting it with several smaller units to make sure it gets the combat it wants. A completely different approach is to play a mixture of minimum sized units of elite infantry, or monsters, or hard hitting cavalry and chariots. A lot of mobile shooting can also be used to "dance" around the Opponent while Shooting their units.
