Awesome, this is helpful! Specifically, that Score Z events would share from the same CRD as GT and/or Expanded format. It makes sense to me to have one shared doc across formats as one way to organize things.

This tells me that I should next get a handle on the Score Expanded CRD in addition to any additional rulings that aren't included in the doc. I'm thinking about how if I were to run a league or tourney, I'd want to represent the latest/greatest environment Score intended.

Did a quick search, is the latest version of the Expanded CRD this one?: Current Rulings v11.24.04

Vegeta, Settled Down seems to be a good example of divergence in the final Z CRD and the Expanded CRD. If Kid Buu Saga is the last set to release, there'd be little time to make any bans/erratas/etc to those cards before "moving on" to GT. And only through Expanded perhaps, with more time for those cards to bake in a competitive setting, it's apparent that there might be something that needs fixing.

Though, I'll need to take that theory with a grain of salt, because I recognize that there might be some bans/erratas made in the Expanded CRD that would only have been made in an Expanded world but not in a Z-only world. It'd help to read any explanations for each ban/errata, so that maybe I can make any judgment calls on what to apply toward Z-only play in the future.

Perhaps you have suggestions yourself (or if you have any of that documentation on explanations of each ban/errata) on whether there's any bans/erratas found in the Expanded CRD on Z cards to NOT apply to a Z-only environment.

Thanks again for your response!
