>Bracket 1: Exhibition
>Winning is not the primary goal here, as it's more about showing off something unusual you've made. Villains yelling in the art? Everything has the number four? Oops, all Horses? Those are all fair game! The games here are likely to go long and end slowly.
You'll have WotC describing this, and then go on to say.
>Deck Building: No cards from the Game Changers list. No intentional two-card infinite combos, mass land denial, or extra-turn cards. Tutors should be sparse.
By the deck building guidelines, I could make an optimized 'bracket 1' deck, but it absolutely would not fit the dumb meme-pile slop they're presenting it as; 20% of the bracket system is dedicated to this confused identity, where Person A could go "Here's my hat tribal, where all cards feature a hat in the card art! It's Bracket 1", and Person B could go "Here's my gruul counters deck featuring 50$ cards like Bristly Bill! It's bracket 1 because it fits the deck building guidelines"
but this is further compounded when you look at Bracket 2, and it's described as being the 'AVERAGE PRECON LEVEL', which pigeonholes it into the expectation of a contemporary commander precon, but the only guideline difference from B1 is no 'chaining extra turns'. Like, the moment you start including shocks, and fetchlands, you're already beyond the cusp of an 'average precon', let alone once you start including expensive cards that manage to skirt the guidelines, but are still beyond reasonable for what to expect in a PRECON.
Every deck (outside of b1 joke-piles, and unironic b2 precon games) might as well be a 3 minimum ('Beyond the strength of an average precon deck'), if we're going by their descriptions that don't at ALL correlate with their deck building guidelines.
Bracket 5 forgoes any guidelines aside from banned cards, so it's effectively just ignoring the bracket system entirely, it exists outside of the ecosystem.
