If I cast more than one Flight of Doves on the same holding, will the additional honor stack? Silly question i'm sure, but, I just wondered if there were any rules about multiple effects of the same card not stacking on the same target.
i.e I cast Flight of Dove on Acrobat Troup. Then I cast a second Flight of Doves on the same Acrobat Troup. Will I now get 4 honor when I bow the AT for honor?

Yes.

Only that a card can only a keyword once. If five effects give a Personality "Tactician," it's functionally the same as if the Personality had the "Tactician" keyword once.
