Synchro and Xyz need to pair with someone to start having their rating go up and down. Inherently, if nobody did pair up, they'd remain stagnant. However, teachers make sure to encourage people to team up with them as neither dorm is particularly weak and can help a lot with the ranking shifts.

How does this pairing work exactly? Does this mean they can only take part in tag duels? I'm not getting how this works.

Does this also mean that challenging a member of these dorms won't affect your own ranking?
