Here's the situation:
My opponent has one character, and declares a military challenge with him. I have two characters in play, one with a military icon, and one with an intrigue icon. I also have A Game of Cyvasse (Challenges: Each player must choose and kneel a character with an Intrigue icon he or she controls, if able. Then, the player who knelt the character with the highest STR may choose and return a character to its owner's hand.) and A Gentle Prison (Challenges: Kneel 2 influence to stand a participating character and remove it from the current challenge. That character cannot be killed this phase) in my hand.
I want to win the challenge, but my military character has less strength. Do I win the challenge if:
1) Before declaring defenders, I play A Game of Cyvasse to remove his character from the challenge, giving him 0 str?
2) After declaring a defender, I play A Game of Cyvasse to remove his character from the challenge, giving him 0 str?
3) Does the result change if I instead play A Gentle Prison, removing the character from the challenge but not from the table?
