My opponent attacks with Jacob, plays Reuben's Torn Clothes, ignores brown. Can I block with my kings of Judah/Israel if I have Gates of Samaria and Jerusalem in territory? They are protected from opponent's cards, so they can't be targeted by my opponent. The way I see it, they can't be ignored (since they can't be targeted) until they are already in the field of battle.
Gates of Jerusalem (P)
Type: Fortress • Brigade: None • Ability: None • Class: None • Special Ability: Protect evil Kings and Queens of Judah in your territory from opponents’ cards. If one blocks, its special ability cannot be negated and you may draw a card.
Gates of Samaria (RA2)
Type: Fortress • Brigade: Multicolor • Ability: None • Class: None • Special Ability: 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.
