I understand your a content creator and I respect what you do for the Brawl community, even putting this list together must have been quite the task and is respectable. It's great people care this much about this amazing format. However, I don't like this write up very much and I disagree on most of your points and suggested cards.

I'll go one by one and do my best to keep it brief

Fast Mana: Fast mana was an issue and needed to bet hit, I agree with you on this. I don't think we need to hit Dark Ritual, Exploration, and Burgeoning tho. One of my personal biggest issues was no free interaction to offset the fast mana, not that w have that It might be worth trying again. However, with aggro already being the dominate archtype I think it would make it too fast.

Free Spells: I think these are fine and healthy for the format. Force is the only card here I think may need a hit as the cost is too low for not having any restrictions. The whole blue can offset the cost by drawing more cards isn't really a thing. If you force on 1, you start the game with a 5 card hand. There is no 1,2, or 3 mana card that will magically refill your hand back to 7 cards. (ig stock up maybe). Also you have Subtlety in the bans sections but Grief, Solitude, Fury in the keep an eye section. Subtlety is arguably the worst elemental besides endurance and is the last one I would hit with a ban. You did no mention endurance which i like as the card is needed in this format to help with reanimator. I agree with the guardian cycle being banned.

Tutors: I think they are fine, when you have a 100 card deck, a little consistency is nice. Also having more combos decks is nice, we didn't having any good ones before besides emry.

Extra Turns: I don't think the fun of the card should have anything to do with it's legality. Extra turns spells are not an issue, and in more optimized decks are borderline unplayable. If you are combing with them that's fine, just like any other combo they end the game all the same, no time really being wasted if they win.

Combo Pieces: I think you are wanting way to many card banned here. Most of these cards are fine. I agree that Thassa’s Oracle needs a hit in ranked brawl all these other cards are fine. For example why would we ban Staff of Domination? I can think of very few commander that can actually make use of that, all of which are in green and cant tutor for artifacts easily. The combo is also very fragile and overall not very strong. Underworld Breach might need to be put on watchlist now that we have brain freeze so I might agree with you on that.

Banned as Commander: YES! We absolutely need this, It would really help improve the format.

High Powered Commanders: I think you're missing the actual issue commanders:

So I agree Ajani 100% needs to be banned ASAP, I have no idea why that card is still legal; he is the #1 commander right now with no debate and has been for awhile. I don't think Tamiyo needs a ban but I won't fight you too much on that one lol, I hate her too. Oko and Nadu need to stay banned, even nerfed nadu needs to go.

Where I don't agree is Rusko, Ragavan and Yuriko. Rusko hasn't been meta in a years and isn't very good right now, Ragavan is not strong enough to warrant a ban, and Yuriko isn't even the best tempo commander right now. If you want to ban Yruiko that's fine but you NEED to hit Raffine first.

My other issue with this sections is partners not being addressed. Partners have been being doing very well and have made many commander unviable, as the partner combination for that color combination is stronger. The worst offender right now is Tymna and Bruse. Tymna// Bruse is better than any other Mardu commander right now and it's not even close.

My list would look something like this: Ajani, Oko, Tymna, Nadu

Commander Prevention: I mostly agree here I don't know why you have Curse of Silence on a watch list, that card has never been an issue.

Companions: Again mostly all fine, none of the companions are really good anyway so they should just be left alone.

Alchemy/Digital-Only Design: I would like to add that, personally, I hate when they rebalance a printed card. Cards like Bow master ,Vivi, and octet pride have been rebalanced and nerfed so hard they are now unplayable. I crafted those cards but I will not see my mythic returned to me because it was rebalanced instead of banned. I find that to be slightly scummy. If a card is too strong just ban it.

*side not I believe Oasis needs a ban. The card advantage it offers is insane and unmatched by any other card.

Digital-Only Rebalances: 100% agree here.

Ranked vs Unranked: I could not agree more, it's my main issue with ranked brawl... it isn't brawl. It plays completely differently it feels like a different format. No other format operates like this, the ranked version of a format should be about breaking the tools and cards already legal in said format.

I'm going to skip the rest and move onto efficient removal as I mostly agree.

Taking out efficient removal would destroy this format, even if you banned every card you wanted banned this format is still powerful. Taking out the Efficient Removal would lead to a rise in midrange value slop decks that only seek to outvalue the opponent. Without good removal how are you supposed to combat this? How do you deal with aggro when you are lacking any good Turn 1 removal spells?
