2 quick Greatjon vs the Joust Keyword questions:
1. If you attack with Arya Stark (TftH) and force the opponent to declare no more than 1 defender due to Arya's Joust Keyword, can you kneel Greatjon to participate along side Arya in the following player action?
2. If you are defending against an opponent's solo-attack with a Joust Keyword Character, can Greatjon kneel to join the challenge in addition to your "1 declared defender?"
