[They're in agreement, although Jester's concerns about being played would be well....laughed at. Chiron's too earnest a horseman to actually do something like that.]

Is there a limit on how many cards one can swap out? For example, could I exchange my entire hand, or am I required to hang onto a certain number of cards?

[The question is genuinely seeking clarification, rather than trying to pull a fast one.]
