Haku could have been a deadly spellcaster. [Almost] No one else could form seals with just one hand. Aside from that, he had three elements at his disposal - wind, water, and unbreakable ice. Imagine him double-casting two spells (using one hand each). Probably a wind tunnel to immobilize the enemy, rapidly followed by a water dragon. Then a frigid damsel as the water dragon makes contact with the foe, encasing him in an ice dragon. A shattering spell could come next; as the icy shards fly in the air, a wind vortex would create a renamon-esque diamond storm.
