Very creative and well-curated deck! I don’t really have any suggestions that you probably haven’t already considered or that would meaningfully improve the deck, but I’ll still leave a few that came to mind and might eventually make sense: Relic of Progenitus, Lantern of the Lost, Dauthi Voidwalker, Leyline of the Void, Lithoform Engine…

Nadier's Nightblade, Mirkwood Bats, Sting, the Glinting Dagger, The Fire Nation Drill, Night Market Lookout, Costly Plunder, Cranial Plating, Agent of the Iron Throne.

theNeroTurtle, I agree with clayperce. It seems to me that the changes you’ve been making already show the direction you’re heading in. What needs to keep being done is continuing to filter the Angels and solidify the manabase. The focus should be, above all, on that and on card draw.

Some other options to keep in mind going forward, considering what I mentioned and also the possibility of exploring different approaches (+1/+1 counters, tokens, and so on): Herald's Horn, Vanquisher's Banner, Conjurer's Mantle, Patchwork Banner, Stoneforge Masterwork, Warrior's Resolve, Cathars' Crusade, Court of Grace, Teleportation Circle (with Inspiring Overseer or Karmic Guide), Together Forever, Cut a Deal, Split Up (just because it’s better than Guan Yu's 1,000-Li March), Sword of the Animist, Door of Destinies…

Going 100% Angel tribal is clearly a challenge, not only because of the high average CMC, but also due to the strategic limitations. A broader card pool would allow you, among other things, to streamline the deck and make it faster and more consistent (Bishop of Wings, Esper Sentinel, Mother of Runes, Selfless Spirit, Starnheim Aspirant, etc.). That said, there are a few other (not many) options worth considering, such as Lightstall Inquisitor or Inspiring Overseer, just to name a couple.

Pariah seems like a good idea to me, although I personally prefer Mithril Coat, as it’s more solid and less restrictive, to accompany it. If Pariah is staying, then Metropolis Reformer should definitely be taken into account.

I believe the creature count should be significantly reduced and replaced with more cheap interaction and possibly some assorted stax pieces (Aura of Silence, Ghostly Prison, Rest in Peace, among others — white has no shortage of options). This would slow down faster decks (which is almost all of them) and help you manage the game until you can either set up board wipes or reach the point where your Angels are established and fully online on the battlefield.

On top of that, Folk Hero would fit here like a glove. The same goes for Archaeomancer's Map, Akroma's Will, The Seriema (even if it strays a bit from the theme), and Throne of Eldraine.

Feel free to check out my Giada's deck as well if you'd like on my profile's page.

Go for it — cheers!
