Not bad at all. You may want some mana rocks, since they can be ramp early game and creatures late game. Here's a few I found:

Mind Stone, Thought Vessel, Worn Powerstone, Cloud Key, Semblance Anvil, Darksteel Ingot, Dreamstone Hedron, Thran Dynamo, Hedron Archive.

8bitmadness: Mystic Decree has too high of a mana cost :(

FlabbyGabby: Spirit Mantle seems fun enough, but several of my cards revolve around opponents choosing which creature to block Zur with! This is why I have cards like Hyena Umbra, Blessing of Leeches, and Charisma!

WithengarUnbound: I totally thought about those because I considered them strongly for my dragon deck. Here's my take on them, particularly for this deck: Notice how Semblance Anvil only comes into effect when the thing I'm casting is a spell! When Zur attacks, I throw the enchantment directly onto the field, completely bypassing the spell casting step. This is why, even with cards like Diplomatic Immunity affecting Zur, I can still put enchantments onto him via his ability.

Furthermore, for a card like Cloud Key to be effective in my deck, I would want it to reduce the cost of enchantments across the board, affecting the cards in my deck before they even see play. This is unfortunately not the case because of the keywords "Spells you play" T.T

Out --> In (+/- CMC): Reason

Urza's Incubator --> Cloud Key (+0): Urza's Incubator is not worth $20 to me; then again is CK worth $8 for this deck?

Teferi's Protection --> Ghostway (+0): TP is another $25 card that I'm not interested in adding here at that price. Ghostway only wrath-protects creatures, so that will have to do.

Hindering Light --> Grafted Exoskeleton (+2) I'll go slightly more in on the infect backup plan. HL is underwhelming more often than not.

Plains --> Scavenger Grounds (+0) This deck needs some way to interact with the Graveyard.

Stroke of Genius --> Tezzeret's Gambit (+0) Nudging higher on infect plan B.

It's a bit clunky at times, but generally the engines you need for storm are a cost reducer like Herald of Kozilek, Etherium Sculptor or Cloud Key plus a draw engine such as Vedalken Archmage , Null Profusion, Future Sight or Necropotence, or a recursion engine like Salvaging Station

This usually allows me to storm out by spamming 1cmc artifacts for 0 and drawing a card for each artifact i play, then playing more free artifacts until I draw into a Tendrils of Agony, Aetherflux Reservoir or Reckless Fireweaver and play enough artifacts for lethal damage

Also, theres a sneaky infinite combo here with Saheeli Rai's -2 and Mycosynth Lattice, where i can make infinite copies of saheeli which is infinite damage with fireweaver and/or Disciple of the Vault :)

But in order to set all of these up, I simply cast a cantrip on turn 1 such as Sensei's Divining Top Ghoulcaller's Bell, Codex Shredder, Shadowblood Egg or Chromatic Star and use the cantrip to draw into more cantrips or a wincon/any of the engines i mentioned

Salvaging Station is actually a beast for card draw here, since it allows me to reanimate any of said cantrips once per turn and potentially many more times (creature death, untapping it)

Urza's Incubator. I think it'll do more of what you want than Cloud Key. Insurrection is hard to beat as win-cons go. Herald’s Horn is respectable with your 18 angels, and same for Heirloom Blade. Your biggest weakness is card advantage. Might wanna get Alms Collector too, c17 was kind to boros tribals. You might consider wheels. could do worse than Staff of Nin, and Sword of Fire and Ice if you want a second mortgage.

I dislike Divine Deflection, I don't think it's enough to turn the tides when you're in trouble, and you won't always have enough mana to make the difference.

I don't love Oketra's Monument for you, the only real synergy is with your general, and I don't think it deserves a slot...focus on fatties or tokens, but probs not both. Same reason I don't love Hero of Bladehold or Odric, Lunarch Marshal.

Aetherflux on its own is not enough even with Hurk recal and chain of vapor. You pretty much need to include scepter and reversal at minimum. 15 mana rocks is more than enough for that combo tho. Tendrils of agony is a terrible win condition that will more often than not lose you the game when you cast it instead of winning. If you want to go full storm then maybe include a Future Sight Sensei's Divining Top Cloud Key combo or a Sensei's Divining Top Basalt Monolith Rings of Brighthearth combo both are great for using Aetherflux Reservoir. I would going all in on reservoir is bad though. You could include a Tainted Pact lab man win in there if you wanted.

Cloud Key, Herald of War, Herald’s Horn, Oketra's Monument, Pearl Medallion, Semblance Anvil,

My wife's deck is blue white so she can run Warden of Evos Isle, Council of the Absolute, and Grand Arbiter Augustin IV

I like the Herald theme of the ramp.
