The link pokken posted addresses exactly this, from a member of the CAG. "Many RC and CAG members, myself included, sympathize with the concerns of the cEDH community in regards to Flash, Oracle, and its metagame issues in general. We have heard your concerns and have been in conversation with luminaries of the cEDH community almost continuously in the past few months. We understand the nature of the problem, but we have our own concerns about how making a ban solely for the benefit of cEDH players would be perceived by the broader community and if it would actually serve to "fix" that end of the format. We worry that it would just be a bandaid over a deeper wound and that we would all end up in the same position again in six months or a year.Airi wrote: ↑4 years agoThere's a weird amount of non-cEDH players in this thread that seem to think that their personal dislike of cEDH justifies not only ignoring the cEDH crowd but actively shutting down their involvement in the format.
You don't need to agree with the way that someone enjoys this format, nor do you necessarily need to agree with their stance on a ban, but I think it would go a long way for a lot of our community at large, not just on Nexus, to have some empathy for the situation.
Additionally, while Flash may not see much casual play, there is nothing to say that recent printing of cards such as Arena Rector or Nyxbloom Ancient won't lead to it seeing wider adoption in the community. While I'm personally of the opinion that Flash should be banned, that opinion isn't universal among the RC and CAG, and many wish to be more cautious about making such a change. What if the next card to break cEDH is something like Sol Ring or Cyclonic Rift? Should such broadly played cards be banned for the sake of the competitive edge of the format? These are the questions we have been considering."
Most casual players don't have it out for cEDH players blindly. I know no true cEDH scotsman is supposed to pubstomp, but it does happen and with more regularity the more popular cEDH becomes. I assume that's where some of the bitterness comes from. But what I really don't like is this attempt to commandeer a format that was designed for casual play, with a banlist that serves that goal. It seems disrepectful and at worst, entitled. When the banlist announcement happened a few days ago, there were more than a few angry cEDH players promising to pubstomp EDH players with flash hulk until they get what they want.
I personally don't want to start down the slippery slope of competitive minded bans. It won't stop at flash, especially as new and more powerful cards are printed. cEDH is singleton vintage, the banlist would need to be extensive for true competitive balance.
