Because you mentioned card advantage, have you considered the following?

Smuggler's Share:Anytime an opponent draws an extra card is often. Plus, the random treasure every now and then.

Well of Lost Dreams: You have Dawn of Hope and the well is similiar but has a much higher ceiling. Big beater and mana open can easily net 4+ cards.

Court of Grace: On theme and keeping the monarch is easier with a bunch of fliers. Will at least replace itself and give evasive chump blockers.

An unrelated card to card advantage would also be Reconnaissance. It's purely for combat but allows you to swing with impunity with every creature every turn. Unfavorable block? Untap and back out. It also grants pseudo vigilance since you can untap and remove from combat after damage with zero downside.

Like the deck. Honestly looks good as is but alas, we are never finished tinkering.

RiotRunner789, you are 100% correct - the quest for perfection is never complete.

I just feel a certain way about some cards for no apparent reason, and Smuggler's Share is one of those cards I just feel iffy on. I don't really have a good reason as to why - I just don't really like it for whatever reason.

I thought about Well of Lost Dreams. Honestly I kind of like it more than Dawn of Hope as you could potentially pay 1:1 instead of 2:1. However it comes with the downside of being two more mana. Honestly though thinking about it I may end up swapping the two. You might've convinced me.

As for Court of Grace, I just don't vibe with the Monarch mechanic. I don't really have a good reason as to why, I just don't. I could consider it as you're right - protecting the Monarch title is easier with a bunch of fat flying angels. I'll consider it.

As for Reconnaissance, you might've just convinced me to put it into another deck I run, Adeline, Resplendent Cathar. I had been considering it for some time, but I completely forgot about the cleanup step after damage is dealt. I didn't even consider using it then, haha. Unsure about it for Giada, but definitely for Adeline.

You cant use cards like Flooded Strand and Angel of Jubilation together. You are paying life to activate the effect of the land.

abstractfive Thank you for your comment!

I'm very well aware of that. The fetchlands are too good not to run and Angel of Jubilation is the only card in the deck that turns them off. The odds of them interfering with one another in an actual game environment is low. It's a bit of a non-bo but I'm still willing to run them.

Heyo, love the deck and theme. Quick additions from a fellow Angel Beats player: Sigarda's Aid will help out with all of your awesome Equipment. Serra's Emissary can protect your Platinum Angel from Instants and you from Creatures. And I would suggest running Helm of the Host or Blade of Selves for multiples of Giada and for fun! Also, I would run Reprieve in the deck as well, since you have Approach of the Second Sun to really lock in that win! Have fun and I hope to see more!!!!

JackNavi Thank you for your comment!

I had no idea Reprieve worked like that. That's nifty! I'll definitely consider it!. As for the other suggestions, I'm not wanting to be too in-depth in the equipment subtheme. I do run a few because I do want to be swinging, but I'm not really sure Helm of the Host or Blade of Selves is the direction I want to take the deck.

As for Serra's Emissary, it just makes me wish Iona, Shield of Emeria was legal >_<

Allow me to begin by thanking you. I've taken a lot of inspiration from this deck in crafting my own Angel deck.

I wanted to ask: Regarding Traveler's Amulet, is this manner of Artefact worth it in mono-colour deck? It seems like we wouldn't really be gaining much value from it, or am I missing something?

Anatak thank you for your comment! I'm glad you've been inspired to make your own Angel deck!

As for Traveler's Amulet, I like it as we can tutor for a basic and help to thin the deck. It isn't absolutely necessary, as you could probably get away with something like Extraplanar Lens if you really wanted to. Plus, it can be recurred with Serra Paragon so we can get more value out of it.

Land Tax would be the best addition. You could also consider Deep Gnome Terramancer since he can potentially get you multiple lands per turn cycle (or potentially nothing but same if you have the most lands for a ton of white cards).

You could consider swapping out Marble Diamond with any other 2 cost rock that doesn't enter tapped. There's Arcane Signet and Fellwar Stone for white or Everflowing Chalice if you end up having more than 2 mana you can spend.

RiotRunner789 you are 100% in the right and I am an idiot for completely forgetting about Arcane Signet over Marble Diamond, haha. This is why I get other people to look at the deck for me; so they can see things I've missed!

I'm a big fan of the Marble Diamond cycle but with power creep/more efficient options, they are in almost none of my decks.
