By giving each faction a prefix and a suffix like word we can create an easy to follow naming conventions to make it more obvious to tell what a dual deck is at a glance. This is helpful for those of us with like 30 decks. Here are some suggestions
Descendents of- -Dragon
Also, you can replace one of these words with a character name. My Dark Dawn deck has a Pras, Traitor of Dawn as a commander so I named the deck Traitor Dawn. I also have a Demonic cult I might rename Gluttony Cult given that the Gluttony Demon is the main commander. This point here is just to make looking over your decks easier.
