A couple more things (I love throwing these out - w -)

For one, the Teams are not always boundaries for who you can expedition with. A person from Team Treasure, for example, can end up doing a mission with someone from Team Etc, and vice versa. For the record, we're using the new limit for number of Pokemon that can go on a mission. So, up to three Pokemon total can enter a dungeon, with the exception of escort missions, which will make the escorted Pokemon a fourth entrant.

There is an exception to this, and that is guild explorations! These range from those that the entire guild go on, and those that only two teams do. The former is usually handled by splitting up for different paths, but the latter acts like a regular dungeon but with two teams. Each team can bring two members, making a total of 4 for the "party". Because these missions will be the first mission for certain newly found areas, you are unable to do this and select an escort mission for it (so the maximum at times should always be 3 Pokemon, 4 in certain instances, and no more).
