I meant no cards in deck as in no cards anywhere -- so no cards in hand, Duration cards, Prince, Horse Traders, etc. Guess that wasn't clear. And oh, solutions I was thinking of (there are 2) have been mentioned:
Alms or coin tokens
EDIT:
I guess Borrow / Poor House also works.
EDIT2:
Would debt cards work? (I still don't know the rules regarding Debt.)
