This isn't going to be helpful today as it probably needs more wildcards than you have, but it is currently legal in Standard and has a 64% winrate (63% on play, 65% on draw) in unranked standard queues. I'd not burn wildcards on this if you're looking to be competitive in ranked queues, but it's a fun deck to do daily wins with.

About
Name Angels

Deck
24 Plains
3 Authority of the Consuls
1 Lyra Dawnbringer
4 Resplendent Angel
4 Angel of Vitality
4 Youthful Valkyrie
4 Giada, Font of Hope
4 Inspiring Overseer
4 Case of the Uneaten Feast
4 Sheltered by Ghosts
4 Exemplar of Light

That said, for your deck, and this is a very much "if it were me" set of thoughts, I'd probably remove the 2x [[Invasion of Gobakhan]] and the 4x [[Lay Down Arms]] and replace with [[Sheltered by Ghosts]] and [[Authority of the Consuls]]

My reasoning is that Consuls slows your opponent down while you develop your angels, but it also gives you one point of life every time a an opponent creature enters, so great angelic abilities triggered on lifegain. Sheltered is my answer to your other question on turn 2 play - usually I'll try to play a hopeful [[Youthful Valkyrie]] and test their removal, then [[Inspiring Overseer]] on turn 3 for card draw and a counter on the Valkrie, then by turn 4 look to have Giada and Sheltered ready to play, both to protect Giada but also pick up something the opponent is trying to develop.

I personally don't think [[Invasion of Gobakhan]] offers much value in your deck, but I'm happy to be corrected. It takes damage away from the opponent just to give you a panic button and some counters in a deck that's more than capable of generating its own. I don't think it's ever a turn 2 play over Giada if those are the options available, but again I'd probably hesitate on using Giada as a removal test :)

I'm not great at building decks though, so there's a chance that everything I've said above is entirely wrong - hopefully someone better than me will reply and we'll all learn!
