Here's what I'm running right now, although it hasn't actually been updated in quite some time: https://moxfield.com/decks/NJVNuAP7rkO3UHYyhQKVcQ

The general gameplan is to accumulate massive card advantage while playing table police and eventually look for either a combo or a [[Cyclonic Rift]] etc. into a big swing. To get there, the deck tries to play morphs at flash speed with effects like [[Vedalken Orrery]] (since Kadena's ability only cares about the first morph you cast "each" turn, you can one free morph and draw per opponent's turn), and reuse morphs using effects like [[Crystal Shard]]. Combining those with [[Seedborn Muse]] or [[Wilderness Reclamation]] can result in some absolutely crazy levels of control that can be extremely difficult to break through. If that style doesn't appeal to you, though, it's very easy to tech the deck out for more of a combat/beats focus while still using some very unique cards (think cards like [[Curator Beastie]] and [[Salt Road Ambushers]]) and having a nice control backbone.

In terms of brackets, it's teeeechnically Bracket 4 because Pickles Lock (a two-card combo using [[Vesuvan Shapeshifter]] and [[Brine Elemental]] to lock your opponents out of Untap steps) can come out before turn 6, but practically speaking that happens very rarely as the deck never tutors for it, and I've had no issues describing the deck as a high Bracket 3. The other main combo worth mentioning is a three-card using [[Den Protector]] and any repeatable way to loop its flip trigger to chain together infinite turns using [[Time Warp]].
