I encourage everyone interested in practicing their Codex to sign up for the ongoing PBF tournaments. It’s a great way to get in some reps in a play-to-win environment.
I’m currently running two ongoing series:
RACE (Now taking signups for RACE #3), which is a more casual series that allows for lots of round-robin play, with a Top 4 for bragging rights.
CASS, which is a seasonal series of swiss tournaments, more seriously minded, and possibly leading to some sort of qualifier for FSX. The next in this series, CAWS (Codex Asynchronous Winter Swiss) will start on the first day of Winter: Wednesday December 21. These are a lesser time commitment, running one match per week.
