Depends Seraphim-Dragon has Light and Holy fire, but Phoenix-Dragon can control Esoteric Flame (which has Unholy Flames), and Magic Immunity. They both are immortal and immune to fire as well, but if the Phoenix has control over all types of flame then it might win. Then again it really depends how powerful they both are in their respective roles.
