What is the best chaotic card?

For my top six, I would say, Lord Bon Blout, Maxxor, Chaor, Cromax, Maxxor Protector of Parim, and Chaor The Firce

There are many good Chaotic Cards, it all depends on your personal preference. Obviously the leaders of all four tribes will be the best. However there are exceptions. Lord Von Bloot, and Heptadd are not leaders but are still very good. Maxxor Protector of Perim and Chaor the Fierce aren't necessarily good.
