My opponent has Self-Control on a hero in territory. He attacks with that hero and I block with Sadducees. My initiative, I play Seek and Destroy and discard a hero in his territory. Still my initiative, I play High Priest's Plot. Can I discard a good card from opponent's hand?
Self Control - Place on your clay or teal Hero: Protect your hand and deck from opponents' cards.
Seek and Destroy - If only one Hero is in battle, evil discard abilities gain regardless of protection. If used by a N.T. Evil Character, discard a Hero. Cannot be prevented.
High Priest's Plot - If used by a Sadducee, look at one opponent’s hand. Discard one good card in that hand. Cannot be negated if Judas Iscariot is in play.
