Withdrawal deals

Do not forget, that those withdrawals HAVE to be played out. That means emptying the library, don' t losing blood or pool after the announcement of the withdrawal. Because in that gamestate ousting of the withdrawer is more than possible and oops! gamewin gone.
I do not like these deals, as they often enough punish players, who played good and managed to get their prey in ousting range and then some smarta** plays kingmaker for a VP.
But they seem to be covered by the rules.
