New Blood and DFCs

Does [[New Blood]] change the instances of a creature type on both sides of a DFC? The exact interaction that came up for me was casting New Blood on [[Kuja, Genome Sorcerer]], changing Wizard to Vampire. He flipped on my end step to [[Trance Kuja, Fate Defied]]. Does Trance Kuja double all damage that my vampires do?

Thanks in advance!
