"He is no fool who gives what he cannot keep, to gain what he cannot lose."
Does Bacchanalia (add one card to your Clientele, etc.) have to obey the card number limits set by the Influence (on the size of the Clientele and of the Vault)? i.e., can one for instance add a card to the Clientele even if the Clientele already contains its "normal" maximum number of Clients?
You must still abide by the vault and clientele limits, yes.
