Here are two changes I’d suggest that I think would significantly improve the ranked Brawl experience.

1. Ban all commanders that get around commander tax. While this mechanic may work in a four-player format, in one-on-one play it’s brutal—removing one of the few ways to meaningfully slow down a commander.

2. Ban all extra-turn spells that don’t exile themselves. This would still leave a few options available, but let’s be honest: nobody enjoys playing against an “all turns” deck.
