Orange king is a must with gomer in the mix. And i personally would take out broken cisterns for gibeonite trickery. Zeresh is great too because of her low numbers, she is persian, female characters are usually harder to get rid of because some enhancements say target "male character", and when haman and zeresh band you get the awesome effect and their numbers arent that high so in some cases you will have initiative to go into your haman plot or gibeonite trickery.
