Two Questions...
1. When you initiate a Challenge, do you have to first declare attacker(s) that are in play first and then use Hidden Vale Pass to add Clansman attacker(s) to the challenge OR Can you initiate a challenge and then use Hidden Vale Pass to add your attacker(s) to the challenge?
2. And when you initiate a Challenge..lets say an Intrigue challenge, can you use Hidden Vale Pass to add Clansman attacker(s) that don't share the same Challenge Icon or do they have to share the same Challenge Icon?
