Dragon sight says " If if is Summer,when you declare a challenge type,your opponent must declare defenders before you declare attackers. The opportunity for your opponent to declare defenders after you declare attackers is lost."
When I declare a challenge type, my opponenet must declare defenders. My question is that if he has to kneel those characters at the same time, or just to declare and do not kneel before I kneel my characters as attackers?
The other question is what about a character with naval enhancement controlled by defender? Can he declare that character as defender via the naval enhancement after I declare attackers?
