What are the best units to turn into Prophets?

[Ewierl]

In Dom2, there were some Abysian units that changed identity when prophetized; the Anathemant Dragon just got a cooler sprite IIRC, but the Warlord definitely changed to a version with better weapons.

One of the Ctissian clerics changes as a prophet... I can't remember if it's the lizard king or the high priest. The new version has a purple robe, but I don't know if it has any real advantages.
