Essentially. It looks a lot like the new Challenger deck they just announced, but does look slightly different

Idk...I feel like [[elvish mystic]] should be replaced by the clearly far superior [[llanowar elves]]

16 land is tight, I would ideally go up to 20, but if you're trying to keep it loaded consider 18.

Same mana cost, but the archetype not only does first strike at all times, but strips your opponents first strike, and it is an enchantment which meshes well with your commander

I like it, though I would replace the [[chieftain en-dal]] with an [[archetype of courage]]

1 more mana but also gives double strike

[[true conviction]] would be better than [[noble purpose]]

A Green deck that only plays lands on its turn? Genius.

Very nice, though Captive Audience might not actually fit all that well with the exceptionally high mana cost, though i'll admit it is a bomb. Consider [[ill-gotten inheritance]] as an every turn spectacle enabler.

I love it! Though I do have suggestions:

Drop the highland lakes and replace with basic land. And I would also replace all the izzet guildgates with [[sulfur falls]].

My reasons for the above: with the lakes and guildgates you have 8 sources of mana that enter tapped, which will slow you down in the early game and be a pain in the mid to late game. keeping the steamvents is solid, because if you don't need the extra mana that turn t'll enter tapped, but its there if you need it. With sulfur falls, most of the time you'll have mana enter the battlefield untapped and ready to use. This is especially important when you only roll with 18 lands.

Not a bad start. Obviously you'd want to cut it down to 60 cards first. Some ideas:

replace pacifism with [[arrest]]
replace 2 plains (or 2 seraph sanctuary) with [[emeria, the sky ruin]]
drop pristine talisman all together
drop the angelsongs
either cut seraph of the masses or at least cut copies to 1 or 2, you arent going to have so many creatures all the time that its worth it
requim angel is nice but I would only have 1 since spirits aren't angels
Herald of war is good, but you do not have really any auras or humans that benefit from it, I would cut
luminous angel I'd cut, goldnight redemeer as well

Yes absolutely [[sulfur falls]] is an excellent addition, I completely forgot about them.

I like it, but I feel like you have too much mana that comes into the battlefield tapped, which slows down your deck a lot. I would cut all the highland lakes and even the guildgates for basic lands, probably 5 mountains and 3 islands. The steam vents are worth keeping even though they enter tapped because if you're in need it can be worth it to pay the 2 life.

I don't think you need 4 flagstones of trokair. It is a good card, but you can only have 1 in play at a time, and it is not like you have any cards that have you sacrificing lands to utilize it. I am assuming you put it in as a defense against land destruction, which is fine, but 2 copies would be more than enough. I would replace with [[emeria, the sky ruin]] as it is not legendary and also has an amazing secondary ability that you can benefit from.

I would also main board Pearl Medallion and that card is amazing in mono colored, awesome enough that I would swap out the Beacon and Pariah

Thats fair, but there are a ton of good angels in that deck that you can pull from, as well as supports. Some of the bigger, higher mana cost creatures may not be up your ally, but there are enough cheaper ones to make something solid.

https://www.mtgvault.com/adkrull/decks/edh-angels/ This is an angel themed commander deck, I would recommend taking a look at it for inspiration. [[lyra dawnbringer]] is an absolute must. I also like [[resplendent angel]] provided you have a lot of life gain (which you totally should).

Would replace the pacifism with an [[arrest]] as shutting down activated abilities is worth the 1 extra mana

Mono white or multicolored?

Korlash....I love Korlash

I would add the artifact lands to this. [[darksteel citadel]] [[seat of the synod]] [[vault of whispers]] [[ancient den]]
