King Omri - Search your deck for one Samaria Site and put it in play.
My opponent attacks with any random hero with toughness 6 or less and I have GoS in play. I block with King Omri, putting a Sam site in play and targeting their hero with GoS. Since GoS is outside of battle, and King Omri is not directly removing the hero from battle, does the opponent get SI to negate or interrupt Omri?
