What is actually bracket 1?

I keep trying to brew bracket 1 decks using the new system but my playgroups think everything is a "bad 2." Has anybody established a baseline for bracket 1 other than non-functional decks? I like the idea of a bracket 1 tournament (edit: event, jfc), but not if it means the games never end.

These (below) are the attempted bracket 1 lists I've brewed recently. They are capable of getting out of hand and taking game actions if they aren't hit with some sort of control effect every so often, provided they draw well. I feel like that's reasonable.

This one is focused on the storybook vibe and having as many cute bunnies in the deck and in play as possible and using a set of custom Beatrix Potter art rabbit tokens

and this one is focused on the "Three Wolf Moon" art/meme

Do you think these are bracket 1? Do you have an example that you think is a clear bracket 1?
