OK, here's my hot take on Commander Brackets after two weeks, since I'm not a content creator, and don't have a public platform to otherwise say anything. (Thats the only way to be heard right?) I've attended three LGS game nights, and played both against friends and strangers. A total of 12ish games maybe?
1.) Bracket 1 and Bracket 5 decks are rare. So rare, I'd say they don't exist for practical discussion.
A, The cEDH crowd doesn't need to search for me at my LGS to find a game. They already know who their opponents are.
B, The ultra-casual exhibition players already knows they're not being competitive before they sit down. If they only selected pods based on congruous Brackets, they would be sitting out waiting much of the time.
So that really just leaves Brackets 2-4 to
consider, which is defined basically by the amount of game changers (0, some, or 3+)
2.) To my knowledge, no one intentionally ADDED game changers to their deck to raise their bracket number and make it better. No one told me in any pregame conversation, "Hey my casual deck just isn't getting it done, so I'm putting in an
Expropriate to make it better because WotC said it would help me win more often". Nope, that wasn't said. Folks with existing decks played them as-is, because the deck was already designed. Being locked into a game at Level 3/4 because of a few game changer cards just didn't seem to sway them anymore than before.
3.) To my knowledge, no one intentionally REMOVED game changers from their deck to slide into a lower tier. Those decks were already made, with cards they already bought and owned. I didn't hear anyone say, "hey i feel bad playing '
Trouble in Pairs' against you because it came in that precon I bought last month". I think people use the good cards they own because they own them, regardless of what Bracket it lands in. Is WotC saying don't use the cards you paid money for? Hardly.
I will acknowledge after the first week of sarcastic jocularity, week 2 had a more legitimate conversation. But I really don't think its going to change the way matchmaking is accomplished at my LGS in any notable way. To me, having the different bracket tiers is tedious; i really just want to play Commander, not Commander2, Commander3, or Commander4. This format became the most popular format on its own, with out a structured bracketing system telling us mathematically how powerful our deck my be.
Outside of the RC making a surprise ban on a few cards last year, would this have ever happened on its own?
