A rookie can add new life to a team. That's what all the Guilds in Guild Ball are hoping to achieve with the Free Cities Draft that happened. The first of those rookies are available, but the second wave is not far behind. If you're looking to pick up Kami, Nomad, Chap, or Flea (bass not included), you can get your name on the list to get them now.
From the announcement:
Kami, Nomad, Flea and Champ are now available to pre-order on the SFG Webstore
