I have a ton of suggestions, so bear with me.

Odric, Lunarch Marshal (pseudo zada for keywords)

Masako the Humorless (pseudo vigilance to prevent crackback)

Runaway Steam-Kin (Makes red instants sustainable for.next turn)

Monastery Swiftspear (prowess with haste for R)

Seeker of the Way (cheap prowess with lifelink)

Tethmos High Priest (reversion of key creatures below 2 mana)

Akroan Crusader (creates soldiers with haste)

Arena Athlete (prevents blockers)

Anax and Cymede (anthems when you target it)

Labyrinth Champion (throws 2 damage anywhere when you target it)

Rogue's Passage (you'll want unblockable, trust me)

I agree with WriteToLive, I would add a few more creatures, and maybe some Swiftfoot Boots.

Also, replace Star of Extinction with Hour of Devastation as it removes indestructible and allows gods to die that turn to damage.

And, one that I happened to forget, there is an enchantment that does the same as Odric, but spreads protection from. Concerted Effort

Minor improvements, your rocks make a lot of colorless mana. Most of your spells are one or two mana, and don't use much or any colorless mana. Replace them with Marble Diamond or Fire Diamond or something similar because I am sure you will find Thran Dynamo will not be as useful as you want.

Akroan Conscriptor with Cloudshift will cause permastealing creatures as a nice combo.

You included some odd choices for protection. Apostle's Blessing >> Faith's Shield or Blessed Breath unless you really think protection from artifacts will be relevant.( Bathe in Light is also good in it's own way)

Niveous Wisps and Crimson Wisps is another solid option from card draw. Guided Strike is decent too.

Magnetic Theft + Sunforger is a nice tutor combo. To be fair you can also steal equipment from other players as well with this without Sunforger

Vanguard of Brimaz and Akroan Crusader can be useful for better blocking and adds more creatures.

For win cons you can think about Aetherflux Reservoir , Sphinx-Bone Wand , and even Sentinel Tower .(even if that one only works on your turn) You can also add Guttersnipe to end games as well.

A Fun add is Intimidation Bolt . Hit you own creature and you can't be attacked for the rest of your game as long as you have 3xplayers mana. (oh look Feather, the Redeemed is a 3/4, and will live from that ;) )
