For real fun, try recruiting the Free Agents Kiyuki, Kyou, Durren, and Vilucha. You can have your Fayth Blitzball team, including the Fayth of (respectively) Sandy, Yojimbo, Ifrit, and Cindy. Somehow the idea of playing Blitzball with Fayth seems eerily appropriate.

For the record, the only unique Fayth are Bahamut's and Anima's.
