Here's an idea if you need more signups or want to mix things up. Have anyone sign up until we get 26. Have a 3rd party who's familiar with the players draft his ideal villager team in one 13er and ideal wolf team in the other. The people who get snubbed have a chance to redeem themselves by winning.
Think of it like the NBA draft, rigged to give the top picks to a team of the commissioner's choosing.
