Brawl, or historic brawl, has become a completely broken format, unbalanced, unfair and straight out unplayable. Let me elaborate. Brawl has seen in recent years the inclusion of many cards to the format. Some very positive additions include fetch lands and the MH2 elementals just to name a few. I personally was really happy to see these cards added to Arena. On the other hand, there have been some very questionable additions like Chrome Mox and the pool of alchemy cards. At the same time, for completely unintelligible reasons, Wizards decided to extend the nerfs from Historic to Brawl. So cards like Guide of Souls, Ocelot Pride, DRC, Unholy heat, Teferi time raveler, etc. are nerfed in the format. The end result is a format where your opponent can have a turn 1 Chrome Mox, into dark ritual into Rusko Clockmaker, but you have to play with a nerfed guide of souls and cannot cast on turn 1 ocelot pride. To me, after many years of playing Brawl on Arena, this situation has made the format straight unplayable. Especially considering that most of the free counter spells are not yet added (or will they ever be?) to the format, i.e. FoN, FoW, Daze, and even force spike! (Which for also completely unintelligible reasons it is added as a draftable spell from a spell book but not as a standalone card).

I understand that Brawl is the format where players want to test 4-player commander cards, but in actuality, the format is most similar to duel commander, also called French Commander, or 1v1 commander. For obvious reasons, in duel commander, most of the cards that cause trouble in Brawl are banned, i.e. Chrome Mox, Ajani (as a commander), Ragavan, Mana Drain, Temporal Trespass, Treasure Cruise, Dig through time, just to name a few. You can find the complete ban list in here:

I play competitive duel commander, and I find this ban list equilibrates the format extremely well. Alchemy cards also contribute greatly to break the format. The now infamous Mythweaver Poq, Rusko, Oracle of the Alpha and their absurd alchemy-specific mechanics like seek, conjure and "perpetual", stablish a clear breach of power level for those of us who prefer not to play with Alchemy cards. I have already explained the Alchemy problem in Brawl in another feedback entry, you may find it here:

I feel many players share my opinion. I have a few suggestions for improving the format, that I hope could be implemented for a better play experience:

1 - Ideally, segregate Alchemy from Brawl. You can still have an Alchemy Brawl format for those who wish to play with this card pool.
2 - Remove historic nerfs in Brawl. If cards like Teferi, time Raveler are a problem in the command zone, just ban it as a commander only (or even better, do not allow planeswalkers in the command zone, which is the root cause of the problem, and a terrible idea overall).
3 - Get more in line with the Duel Commander ban list. There is also no reason to ban cards such as Drannith Magistrate or Medling Mage. I get it, people want to cast their commanders, but these are cards that are part of a game of Commander, and you do not need to infantilize your Arena players.
4 - We are still missing an incredibly large card pool in Brawl, even from very recent sets. Some examples include Pyrogoyf, Broadside Bombardiers, etc, etc. While I understand that including all new cards is a big effort, you are at the same time producing new Alchemy cards 95% of your community hates. Why not devoting that effort to actually include cards you release in paper sets?

Somehow, I doubt Wizards will listen. But if you made it up to here, thank you for reading :) and I hope you give a thumbs up to this post! Cheers!
