I had this scenario pop up a while back in a game just forgot to get clarification on the ruling of it.
The scenario is opponent makes a RA I block with King Rehoboam (Di) to cause a hero in opponents territory to fight Hero King Saul with King Saul's Spear on him. In regards to characters, can King Saul's spear only be used to withdraw a Character in that side battle or can I affect the hero that initiated the RA as well? Basically it comes down to how to how an opposing character in this scenario is viewed.
King Saul's spear SA
You may discard this card to withdraw an opposing Character or negate and discard an artifact.
