Best level 6 unit.

The Knights of Horror are awesome! No one can match them. Except maybe the Naga. It's cheaper than the Naga, has MUCH more attack and defense, and is also faster, with 10 more hit points. The only downside is the damage. The Dark Knight deals 15-30 damage, while the Naga deals exactly 30. In terms of abilities: the Naga only has the ability to retaliate, while the Knight of Horror has: curse, unholy, and double strike (which is amazing with luck!). The choice is obvious...
