Captain
A captain is a player who can choose their team composition. In a Captain Battle they are also the team's royalty.
Assigning Captains
A captain can be anyone that will be playing in the next battlegame. No leadership skill, strategic ability, or veterancy is necessary; the teammates they choose can provide these things. However, a veteran who can gauge fighters' skill may as a captain compose a more balanced team to make the battle more fun, interesting, and productive.
Official Postitions
A realm or practice may have several designated, unchanging captains. It's easier to ensure this way that the ideal candidates, such as veterans, fill the captain role.
There may be a heirarchy of captains, such that the 1st and 2nd Captains normally pick teams but the 3rd Captain may pick a team if one of the other two aren't participating. Acting Captains can also be chosen by captains or marahals, if there aren't enough captains participating, to temporarily become captains.
Captains' Cutthroat
Captains can be determined with a quick Free For All before the battlegames. The last people standing can each either choose to be captain or choose another combatant to be captain. A captain's priority depends on how close they were to being the last person standing. Even if good fighters are more likely to win, there aren't any guarantees with this assignment method, which results in more variety in captains.
If there are official captains, they can fight amongst themselves to claim priority.
Random Pick
A marshal can just pick captains on a whim. It's hardly any less fair than letting captains pick teams on their whims. Marshals should try to give everyone a chance at being a captain to avoid jealousy.
Choosing Up Sides
Before picking teammates, the captains stand next to each other while facing one way, and the rest of the fighters stand in front of and facing them. At least one marshal or veteran should stand in front of and facing the captains, to show where fighters should stand. Captains should have enough room beside and behind themselves for their teams to gather near. The captains pick teams until all fighters are on a team.
First Pick or Second Two
This method is for choosing two teams. The fighters being picked stand next to each other in a line. The primary captain gets to decide whether to pick the first fighter and let the secondary captain pick the next two, or vice verse. The two captains then switch off, picking one fighter each time.
Cycle Pick
The fighters being picked stand next to each other in a line. Captains pick fighters in order of the captains' priority, starting with the highest priority. Once the lowest-priority captain picks, the order cycles back to the highest-priority captain.
Queue Pick
The fighters stand behind each other in one or more queues. As in the Cycle Pick, captains make choices in order of priority. The captains choose to "pick" or "pass" the group of fighters at the immediate front of the queues. For small teams, use only one queue.
On a pass, the queues do not change. On a pick, the front group leaves the queues and joins the captain's team. If all captains but one consecutively pass on the front group, the group joins that one captain's team before the captain chooses to pick or pass, and that choice is made on the following group of fighters.
Balancing between Battles
If the marshals are using a method of team balance that asks for judgement from a combatant on behalf of their team, they can approach the team captain. For example, a marshal can approach the captain of a team that lost the previous battle to decide whether the teams will Stand as they are or what opponent will be Delivered unto their team.
