I made a rescue attempt with Abiathar, my opponent blocks with King Omri and searches for a Samaria site while Gates of Samaria is in play. Am I allowed to play Zeal for the Lord to discard Omri, while simultaneously discarding an Assyrian in my territory, allowing me to negate and discard Gates? I recognize that a regular interrupt the battle isn't acceptable, but I am technically negating Gates with the enhancement, it's just through a couple proxies.
King Omri 6/7 - Search your draw pile for one Samaria Site and put in play. Land Purchase cannot be negated.
Gate of Samaria - Protect evil Kings of Israel in your territory from opponents. When you play a Samaria Site, increase your evil King of Israel 6/6 to decrease a character 6/6.
Zeal for the Lord - Interrupt the battle and discard two Evil Characters of different brigades. Cannot be negated if used by Phinehas, son of Eleazar.
Protection of Jerusalem - Place in your territory: Protect your good O.T. Fortresses from opponents. When you discard an evil Assyrian from play, you may negate and discard an evil card.
