What's in a name? Unicorns are also known as Paladins. Fergus Duniho is strongly in favor of Paladin for the B+N compound, often called a Cardinal. My 2004-08-31 comment to the Piececlopedia page for this piece mentions the commercial game 'Cardinal Super Chess', where the Cardinal moves like a non-leaping Camel.
If you remove ranks 1 and 10 from this variant, you get the same setup as in Daniel Brown's 10x8 variant J-Chess, where the Camels are called Jesters. My TenCubed Chess uses Wizards (Camel+Ferz) and Champions along with the B+N and R+N compounds. I added a comment there giving a mate in four that works even if Wizards are replaced by Camels.
